Great tutorial -- Used NB 6.0.1 and deployed into Glassfish V2 aok

Thank you

Tutorial is ok but quite shallow information. Besides, it does not run with cfx-2.0.4 and spring-2.5.2 (known issue in cxf, solved in 2.0.5 snapshots).

Thank you.

Thanks for the feedback guys, and @Cristian, thanks for the heads-up about Spring 2.5.2.

Awesome tutorial, had it working and debugging with Eclipse3.3, CXF2.0.5,Spring 2.5.2 with Tomcat5.5

Thank you

This is great stuff/Good article.
Thank You

The attribute default-autowire="byName" caused this example to fail for me.

Hi!

Note: I am a beginner for CXF and Spring.

What I would like to know how one should start the webservice?

If using just CXF, there is a class with main method (e. g. here: http://svn.apache.org/repos/asf/incubator/cxf/trunk/distribution/src/main/release/samples/java_first_jaxws/src/demo/hw/server/Server.java)

What is the case here?
What choices do I have?

thanks

Hi Willie,
this is my first web service application example in Java & I like the way you have put the tutorial in simple terms so that a beginner like me can understand it clearly as well.

I have a doubt though, can I pass parameters to postMessage method & if so how?
Please provide me the way to pass parameters in the URL.
Thanks
Cheers

Hi Willie,
I also noticed the use of @overide annotation.
What is the purpose of it?.Is it a typo?
I also got a warning from Eclipse & I couldnt access the getMessages method when @override annotation was used when I deployed the application on JBoss AS 4.2.2GA.
I removed the annoation & the application is working fine now.


Thanks
prasanna

@Makarand and Rajesh: Thanks!

@Richard: Not sure why that is happening for you. If you provide more information I might be able to help. At any rate the autowiring part is optional. If you are having problems with that you can always manually wire the beans.

@Gergely: In my article, the web service is just part of a web application, so you would start it in your web container (e.g. Tomcat). As to the example you reference, that uses the JAX-WS Endpoint API to publish the web service. The idea is that it starts up a lightweight web server to host your web service. Here is a link for you:

http://weblogs.java.net/blog/jitu/archive/2006/01/web_service_end.html

@Prasannarupan: Glad you found the tutorial useful. As far as passing parameters to postMessage(), I'm not sure I'm following your meaning. We are in fact passing an argument to postMessage--namely, the Message object itself. The client doesn't know that ContactUsService is backed by a web service and in particular it doesn't know that HTTP parameters are involved at all (if that's what you're asking). Can you describe more generally what you are trying to do?

As far as @Override goes, it wasn't a typo, but you are right to remove it. @Override tells the compiler that the method is supposed to override a method in an interface or a base class. (So if the compiler doesn't find the overridden method, it complains. This helps avoid cases where you think you overrode a method but you really didn't, like if you implement hashcode() instead of hashCode(), etc.) In Java 5 you can't use @Override when the method in question is an interface method; it works only for methods defined in a base class. In Java 6 you can use @Override in either situation. I am using Java 6 in the article and I neglected to say anything about that. Thanks for highlighting this.

Hi Willie!

Thanks for the quick reply.

Ok, the article shows how to do a web server, but spring is still not involved...
Since it may take up just a few lines of code, is it possible to complete the tutorial to a fully working example, or I'm just the only one who needs this extra.

Hi Gergely. The tutorial's example should be a fully working example :-) though the downloads are in my other Spring/CXF article (the second in the series) at

http://wheelersoftware.com/articles/spring-cxf-consuming-web-services-4.html

One of the links under Resources is the web service (i.e. the example in this article) and the other is the client code. You'll need to grab the dependencies yourself but those are listed in the article itself. Let me know if you aren't able to get the example to run.

By the way, Gergely, I may be misunderstanding you when you say "spring is still not involved", but in my article, Spring is very much involved. We're using Spring to wire up the beans and (importantly) to abstract the service implementation, among other things. Then we're taking the resulting web app (well, web services in this case, but bundled in a WAR) and dropping that into Tomcat or whatever servlet container you like.

The nice thing about Spring + CXF here is that as far as your application is concerned, it's just working with service beans. It has no knowledge that the service beans are actually web service proxies. You can very easily replace web service remoting with some other remoting mechanism (e.g. RMI, Hessian, Burlap, HttpInvoker) and you don't have to change the app at all--just the Spring config.

The app doesn't even know that the service beans are making remote calls, so you can replace the web service proxies with the actual web service implementation bean and the app doesn't know. In fact I did exactly that when I wrote the code for the comment service on this very web site. Originally I was making web service calls to a CommentService I wrote, and then I decided that there was no point and simply replaced the web service calls with a local service bean. Worked perfectly. :-)

Hi!

Well, the problem for me is (maybe just for me...): who will know web.xml must be read and parsed, and where is this piece of information in the code?

ui: I said I'm a beginner in this area.

By the way, with using a Server.java, which is here:
[http://pastebin.com/m5204fe28]

The output of the program looks like this (exception at startup):
[http://pastebin.com/m6366ff96]

Hi Gergely. It looks like you are trying to use the approach at

http://cwiki.apache.org/CXF20DOC/a-simple-jax-ws-service.html

which does not involve Spring or even a WAR. (So there is no web.xml involved with that.) That approach is not directly related to my article.

You might take a look at

http://cwiki.apache.org/CXF20DOC/writing-a-service-with-spring.html

instead, which is one of the other CXF 2.0 howtos (and it happens the one on which my article is based).

Hi,

it seems very usefull tutorial but when i try to do what you did, i got following exception

14:16:30.292 INFO [main] org.apache.cxf.aegis.type.XMLTypeCreator.<clinit>(XMLTypeCreator.java:125) >46> Parser doesn't support setSchema. Not validating.
java.lang.UnsupportedOperationException: This parser does not support specification "null" version "null"
at javax.xml.parsers.DocumentBuilderFactory.setSchema(DocumentBuilderFactory.java:489)

i could not get rid of this problem.

When using Spring 2.4, Tomcat 6 and CXF 2.1 you need to add jaxen library to you classpath ortherwise AegisDatabinding bean won't be created.

Man you saved my life... at least my work life. I've been working with CXF for a month without getting any test running well but simple services which return basic data types. When I've read your post I've realized about the JAXB problem with complex types and then I've took all necessary beans and Aegis configurations from your tutorial and my little service has worked!
Thanks a lot. Greetings from Argentina

PS: sorry about my english, it's quite poor yet ;)

@Federico: Really happy to hear that the article helped you. And your English is fine. A lot better than my Spanish. :-D

Thanks for putting this tutorial together. Was very helpful.

I was just reading through the article and the bottom of page 3 mentions a validation annoyance in Eclipse. I checked to see whether the CXF team had yet posted the core and jaxws schemas to the specified schema locations and the answer is yes. So the validation annoyance I mentioned should not be a problem anymore. (Maybe it will still come up if you aren't on the Internet but other than that...)

Willie, although CXF have posted those schemas to the sites, it still causes an issue if the machine that CXF + Spring 2.5 is behind a proxy with no access to the outside world. I do have a solution that I have used for Spring 2.5 in the past for other Schemas, and once I have tested that it works with this, I will post the answer here and on my blog.

I am using netbeans 6.0.1 added the jar files in the libraray and also using glassfish V2 server , and got the following errors while running the application .

nice doc .. thanks ..
running into a problem after deploying app on tomcat.

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'cxf:bus'

The declarations inside my spring-beans.xml are 100% correct.

Error occurs on both, the ctx suffix as well as the jaxw suffix.

Using spring 2.5.5 and cxf 2.1 (tried older versions as well).
Manually added jdom 1.0 to maven build.

Was wondering if anyone stepped into same problems before .. thanks

Hi Willie,
Can you provide a specific example of the following?:

[path to CXFServlet]/contactus/postMessage?message=... - postMessage operation

@Alex: The specific examples are listed at the top of page 4. Basically you just need to include the URL up to and including the servlet name, so that would include your servlet context and the servlet name just like with any servlet.

I am unable to get it working :( Can you please help?

My war is named cxfwheeler.war

So I access: http://localhost:8080/cxfwheeler/contactus?wsdl

I get a HTTP 404 error, requested resource not found :( :(

I now understand that my context wasn't being loaded due to Tomcat listenerStart error.

I get Tomcat listenerStart while deploying my webapp. Moreover, this deployment error is not predictable, in the sense that I do not get it every time I start Tomcat, may be 50-50 chances of getting the error or not.

INFO: Deploying web application archive insuranceApp.war
Sep 8, 2008 10:09:23 AM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Sep 8, 2008 10:09:23 AM org.apache.catalina.core.StandardContext start
SEVERE: Context [/insuranceApp] startup failed due to previous errors

I am using Tomcat 6.0.14 with Spring 2.5.

What can be the reason? I saw there were 2 other threads in the Spring forum related to the exact same error, but they were being answered by newbies alike trying to guess the reason and thus not much useful.

As a workaround, I am now using the ContextLoaderServlet and commented out ContextLoaderListener. But I would still like to know the reason why.

<!-- <listener>
<listener-class>
org.springframework.web.context.ContextLoaderListe ner
</listener-class>
</listener> -->

<servlet>
<servlet-name>context</servlet-name>
<servlet-class>org.springframework.web.context.ContextLoade rServlet</servlet-class>
</servlet>

I am now able to hit my context correctly, but I do not get any services listed.

Rather I get the following message at the url - http://localhost:8080/cxfwheeler/contactus?wsdl :
"No service was found."

I am sorry for bothering you so much.

Hi Kasturi. No need to apologize; it's no bother at all. :-)

The "No service was found" message comes from the CXFServlet, so at least your request is finding its way to the servlet itself. But somehow the contactus service isn't being registered.

Can you take a look at your appContext.xml file and make sure your <jaxws:endpoint .../> definition matches the one on page 3 of my article? In particular you will need to make sure it says address="/contactus". (Check the case as well.)

That's just a guess, but again the request is hitting the servlet, so it's probably something in your appContext.xml. You might try just downloading the sample code if you haven't already done so.

Let me know if you remain stuck.

Great tutorial Willie - thanks much!

I also had the "No service was found." issue that Kasturi as well. It seemed to be fixed after I got rid of the implementorClass attribute in the jaxws endpoint, as just the implementor reference to the service bean was sufficient.

Thanks again!

I am using CXF to test getMessages and it almost work expect for following namespace issue:

Here is getMessagesResponse SOAP message sent from Jboss to the CXF client:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns1:getMessagesResponse xmlns:ns1="http:// service.texas.mycompany.com /"><return><ns2:Message xmlns:ns2="http:// service.texas.mycompany.com "><ns2:email>willie.wheeler@xyz.com</ns2:email><ns2:firstName>Willie</ns2:firstName><ns2:lastName>Wheeler</ns2:lastName><ns2:text>Great job</ns2:text></ns2:Message><ns2:Message xmlns:ns2="http:// service.texas.mycompany.com "><ns2:email>dardy.chen@xyz.com</ns2:email><ns2:firstName>Dardy</ns2:firstName><ns2:lastName>Chen</ns2:lastName><ns2:text>I want my money back</ns2:text></ns2:Message></return></ns1:getMessagesResponse></soap:Body></soap:Envelope>

Here is and warning on client side:

Sep 16, 2008 6:08:10 PM org.apache.cxf.aegis.type.TypeUtil getReadType

WARNING: xsi:type absent, and no type available for {http://service. texas. mycompany.com}firstName

It seems like problem is in the fact that it is :
xmlns:ns2="http:// service.texas.mycompany.com

My wsdl is available on the ip: http://localhost:8080/root/webservices/contactus?wsdl

How to fix this xmlns:ns2="http:// service.texas.mycompany.com properly?

Great tutorial !!
I implemented it and its working.

Thanks for everything

I used cxf.2.0.8 jar and it worked

hello,

I found this article to be very helpful, many thanks.

I am using latest CXF 2.1.2 and Spring 2.5.4 and the WS works just fine.

The issue I have with running the JUnit, I get the following error:

I have jaxen-1.1.jar in my classpath on Tomcat 6, but I am still getting the following:
Oct 11, 2008 12:45:36 PM org.apache.cxf.aegis.type.XMLTypeCreator <clinit>
INFO: Parser doesn't support setSchema. Not validating.
java.lang.UnsupportedOperationException: This parser does not support specification "null" version "null"

What should I do ?

@len: Yeah, alperen above said the same thing (May 6). I'm not sure what it is. If you're adventurous, you might try cracking open the XMLTypeCreator (line 125) and DocumentBuilderFactory (line 489) source.

It's hard to tell from the limited error message but my best guess would be that you either haven't specified a default namespace or else you haven't specified a schema location for that namespace. Can you post the namespace declarations you're using here? (Don't need the whole config file; just the namespace declarations at the top.)

Willie,

I used the code you have provided. I did not change anything in it, except the web application name under which I deployed the services.

The possible clue may be is it that I used CXF 2.1 ( instead of your example referring to 2.0.4) nad CXF web site states that there are significant changes regarding the use of Aeges 2.1 ( which is currently used by CXF 2.1).

But I would not like to go over source code.

May be you already know,what should be done in case of using CXF 2.1 and Aeges 2.1 ?

Thanks.

Hi Len. I didn't already know, as I haven't used CXF 2.1 yet, but I wouldn't be surprised if that were the issue. Thanks for writing back and letting us know about this.

Awesome tutorial, had it working and debugging with Eclipse Ganymede, CXF 2.1.3, Spring 2.5.5 with Tomcat5.5

Attention:
CXF 2.1.3 with Java 6 requires jaxb-api-2.1.jar (you will need to download it since it doesn't come with CXF 2.1.3 distribuition)

Thank you

First off, great tutorial. I almost have my web services setup. I am running into a mapping/binding snag.

The service methods that take as a parameter or return a java.util.Set are having an issue. I attempted to reconfigure to Aegis as this tutorial suggests. I still encountered the issue. Below is a partial stacktrace when configured to use Aegis. Any suggestions greatly appreciated!

The service interface for IBusinessUnitQuery.findBusinessUnitsByCompany looks like this...

public Set findBusinessUnitsByCompany(Integer companyNumber);

I am using Spring 2.0.7 and have tried cxf 2.0.6 & 2.1.2.

Thanks

I resolved my previous post/question by adding generics to the interface and implementation class.

So, my interface now looks like this...

public Set<BusinessUnitDO> findBusinessUnitsByCompany(@WebParam(name="companyNumber") Integer companyNumber);

I've also had the same problem @len and @alperen reported

java.lang.UnsupportedOperationException: This parser does not support specification "null" version "null"

and fixed it by making the application use Xerces-2.9.1's DocumentBuilderFactory implementation.

A pretty useful article for beginners!

Thank you !

I tried your example and it worked. Good job. I cam accross one issue when I attempted to validate the out going and incoming SOAP messages. I added the following piece to the appContext.xml file:

<jaxws:endpoint id="contactUsService" ......

<jaxws:properties>
<entry key="schema-validation-enabled" value="true" />
</jaxws:properties>
................
</jaxws:endpoint>

and I put the following annotations on the Message class method getFirstName.

@org.apache.cxf.aegis.type.java5.XmlType.XmlElement(nillable=false,minOccurs="1")
public String getFirstName() {
.....
}

Now when I call the postMessage method on the ContactUsService endpoint and didn't pass the first name value in the Message, nothing happened. Its completely ignored.
Another thing if I remove the aegis binding from the appContext.xml file and changed the annotations to @javax.xml.bind.annotation.XmlElement(required=true) on the getFirstName field it validates the soap message correctly and sent back the following SoapFault message:

javax.xml.ws.soap.SOAPFaultException: Unmarshalling Error: cvc-complex-type.2.4.a: Invalid content was found starting with element 'ns2:email'. One of '{email, firstName, lastName, text}' is expected.

Any idea how can I do the soap message validation using Aegis? Or is there any other way I can do this validation using aegis?
I would really appreciate any help in this regards.

To correct my last comment, when I removed the aegis binding from the appContext.xml file it still didnt validate the Soap Messages correctly, I am keep on getting the following soap fault message:
javax.xml.ws.soap.SOAPFaultException: Unmarshalling Error: cvc-complex-type.2.4.a: Invalid content was found starting with element 'ns2:email'. One of '{email, firstName, lastName, text}' is expected.
Any help?

Hi Willie,
The class and interface on a different package to generate wsdl incomplete data

@fanjinchang: eh?

The class and interfaces written in a different package to generate wsdl, only "Wsdl: binding", not (wsdl: message, wsdl: types, wsdl: portType),is not my configuration problems?

Hi Willie,
The class and interfaces written in a different package to generate wsdl, only "Wsdl: binding", not (wsdl: message, wsdl: types, wsdl: portType),is not my configuration problems?
E-mail to tell me I made the case to your mailbox, please help me to see?
Thankyou!

Hi Willie,
I tried your example and it worked. Good job.
After that I attempted to validate the SOAP Message. In order to do this I changed Message class and added the following aegis annotation on the getFirstName() method.

@org.apache.cxf.aegis.type.java5.XmlType.XmlElement(nillable=false,minOccurs="1")
public String getFirstName() {
.....
}

Also I added the following piece to the appContext.xml file:

<jaxws:endpoint id="contactUsService" ......

<jaxws:properties>
<entry key="schema-validation-enabled" value="true" />
</jaxws:properties>
................
</jaxws:endpoint>


Now when I call the postMessage method on the ContactUsService endpoint and didn't pass the first name value in the Message, nothing happened. Its completely ignored.

Another thing if I remove the aegis binding from the appContext.xml file and removed the aegis annotation from the getFirstName() method and replaced the annotations to @javax.xml.bind.annotation.XmlElement(required=true) on the getFirstName field it validates the soap message correctly and sent back the following SoapFault message:

javax.xml.ws.soap.SOAPFaultException: Unmarshalling Error: cvc-complex-type.2.4.a: Invalid content was found starting with element 'ns2:email'. One of '{email, firstName, lastName, text}' is expected.

Any idea how can I do the soap message validation using Aegis? Or is there any other way I can do this validation using aegis?
I would appreciate if anyone can tell me the way to validate SOAP message using aegis.

Hi,

Great article! Hoping you can answer a question for me. Someone in our group is trying to deploy a client web service within JBoss 4.2.3. They are getting a NoSuchMethodException somewhere in the JAXB Data binding jar/implementation. This sounds like a classloader issue to me and I pointed them in that direction but I am wondering if you encountered anything like this and how you would approach it?

Thanks!

@Mike: Haven't run into it, but to me it sounds like a JAR incompatibility issue, or else using an old JRE possibly. Can you post the stacktrace along with the JAR versions and JRE version?

Hi , I want to replace the axis web services with CFX . Currently my application which using Axis and spring frame work is deployed in tomcat 6.0 .

Can some body please tell me what are the configurations files i need to modify/create? . also to migrate from axis to CFX is there any regression issue ? I dont want to change any java code . Please suggest and let me know what are changes i need to do .?

Thanks in Advance . Best Regards, amitava

Hi Willie,

Thanks for the wonderful example. Im new to this CFX+Spring Webservice and so please forgive my ignorance. I was trying to deploy your example and Im getting the below error which Im not able to resolve it.

ERROR [STDERR] Feb 6, 2009 11:19:42 AM org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass INFO: Creating Service {http://contactus/}ContactUsServiceService from class contactus.ContactUsService 2009-02-06 11:19:43,706 ERROR [STDERR] Feb 6, 2009 11:19:43 AM org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass INFO: {http://contactus/}return part element name {http://contactus/}return references element {http://contactus/}return {http://contactus/}message part element name {http://contactus/}message references element {http://contactus/}message

Please help in solving this.

Im trying to deploy the service in jboss 4.3.0.. Please suggest me the method of deploying the service in jboss.

Hi Willie Tried your example and it works fine thanks. But I need to use restful webservices instead of SOAP. Somebody tell me what are the changes that needs to be done for restful..

Thanks in advance.

with respect to the question on postMessage; would you give a specific example to of what to put on the command line to pass in a Message? how to pass an instance of Message in detail.

Hi Willie I write a service following ur example and it ran successfully, then I tried to write a client to access this service, for this when I inspect the wsdl it has missing portType element and hence the XXXXport class is not generating, I am using clientgen of weblogic 9.

Hi Willie, When I am deploying an application as the same like the one in the tutorial but returning a simple java object which is binded using default JAXB I am getting a response with a return tag in it. How to avoid or remove the return tag in the response.

I am trying to create a simple application using RAD 7.5 (WAS 6.1 test server, Servlet 2.4) with CXF 2.2.3 and Spring 2.5.

I have placed all the jar files that come from CXF 2.2.3 download in the web-inf/lib directory.

I am using your example as is for learning purposes.

When I start the WebSphere test server 6.1 (that comes bundled with RAD 7.5), the server starts, but shows the following errors:

 [9/18/09 10:58:07:668 EDT] 00000030 WorkSpaceMast E   WKSP0012E: Exception while extracting cells/TSD-108078Node01Cell/applications/IBMUTC.ear/deployments/IBMUTC/deployment.xml from ConfigRepository--com.ibm.websphere.management.exception.DocumentNotFoundException: cells/TSD-108078Node01Cell/applications/IBMUTC.ear/deployments/IBMUTC/deployment.xml

My web.xml looks like:

   
 MyCxfWebService
 and the rest is code from this web site 

appContext.xml is the same as yours. Java class files are also the same as yours with the same package structure. I only commented out @override annotation.

The 2.2.3 download of CXF does not have jaxws-api-2.0.jar in it. I added it with not result.

I also get the following error as:

 Publishing failed

    Deployment from com.ibm.ast.ws.jaxws.deployer.JAXWSDeployer had errors:  

      Tools for WebSphere V6.1 must be installed in order to generate WebSphere V6.1 compliant code. 

Any suggestion will be appreciated.

Hitting the CXF url http://localhost:8080/security/ws/ says 'No services have been found.'

There were some discussions about this problem in the earlier comments but i didn't find any solution. Can you please help me debug this issue?

FYI I am using spring-3.0.0.M3 jars.

Found out the problem. I was initially using DispatcherServlet in my web.xml and when I replaced it with the CXF servlet I didn't add the myApp-servlet.xml file to the contextConfigLocation(DispatcherServlet loads it automatically). My bad

RE: validation annoyance in Eclipse

This is a strange error. I get this error on Eclipse Gallileo using the Spring beans validator and found that it can be eliminated by turning the validation off, hitting OK and then turning it back on. This appears to work fine but is still unsettling. - Trip

Good simple tutorial, I followed it to build something similar.

However I'm getting an error when my WS tries to return its response object.

The object contains a Set (using a TreeSet implementation) of HistorySummary (a custom POJO class) objects.

When the service implementation class tries to add HistorySummary instances to the Set (which will then be inserted into the response object). I get the following error:

org.apache.cxf.interceptor.Fault: Couldn't instantiate class. com.artifact software.portal.history.messages.retrieve.HistorySummary. Nested exception is java.lang.InstantiationException: com.artifactsoftware.portal.history.messages.retrieve.HistorySummary (I'll spare you the full stacktrace).

Oddly enough, if I instantiate the HistorySummary object but never add it to the TreeSet the error doesn't occur, although then of course, I have an empty Set.

Any ideas what might be causing this?

great article, thanks...

Hi, I tired the sample project given here. It's not working completely. I could access the webservice through the url http://localhost:9083/CXF/contactus/getMessages and get the soap response back.
