2010-03-17T09:12:26.758+05:30

Service classes can be packaged in a jar under WEB-INF/lib or put them inside WEB-INF/classes directory. sun-jaxws.xml should go under WEB-INF and WSDL will be generated at runtime. For accessing web service from other applications you need to generate web service client using 'wsimport' goal of 'jaxws-maven-plugin' plugin.

Thanks Vinod. Sweet. That really helped.

If I were to package these service classes and resources under jar file....
Where should the resources like wsdl files and sun-jaxws should be placed. Should they go under META-INF folder?
And, Since jar file does not have a context, how will I be able to reference the wsdl from my clients or web apps.

Thanks.

2010-03-16T21:26:07.492+05:30

This seems to be class collision issue. Some jars available in your application's WEB-INF/lib diretory may be present in JBoss' classpath as well, which is not the case with Tomcat. Try to findout such jars and remove them from your application.

@kara.cuma

The error message org.xml.sax.SAXParseException: Anonymous types form an infinite cycle gives an impression that the WSDL has some incorrect relationship among various objects leading to cyclic dependency. A deeper look at the WSDL may reveal the exact cause of this error.

2009-11-07T18:52:39.813+05:30

Hello, I'm adding to my previous post.
First of all Serializer.jar, Xalan.jar and xercesImpl.jar have always been in the endorsed directory. To run JBoss on java 6 you have to add jboss-jaxrpc.jar jboss-jaxws.jar jboss-saaj.jar to the endorsed directory as well. See http://www.redhat.com/docs/en-US/JBoss_Enterprise_Application_Platform/4.3.0.cp06/html-single/JDK6_Compatibility_Notes/index.html.
A good starting point for Spring and JEE integration can be found on the Spring website http://static.springsource.org/spring/docs/2.5.x/reference/remoting.html chapter 17.5.5. Exposing servlet-based web services using JAX-WS.
Some JEE application servers have features that make Spring integration a little easier, Apache Geronimo's CXF is actually Spring based and Glassfishes Metro has RI see https://jax-ws-commons.dev.java.net/spring/.
You can use both of these web service stacks with JBoss, but you can only do this using the JBoss distributions of the web service stacks. For more information on this see http://www.jboss.org/jbossws.

2009-11-06T22:43:34.694+05:30

Helle, are you aware that this is totally unsupported.
The reason why Serializer.jar, Xalan.jar and xercesImpl.jar are in the jboss-4.2.3.GA\lib\endorsed directory is because java 6 breaks the webservices stack that is already part of JBoss. You cannot mix two implementations of JAX-WS in the same application server.
You basically have two options. Remove JAX-WS from your application and start using the JAX-WS stack that is part of JBoss. There is some documentation on how to do spring websevices with weblogic on the the Oracle web site.
Or stop using a JEE server and use Tomcat or some Tomcat derivative like Spring DM Server or JBossWeb to deploy your application.

2009-10-30T14:25:43.810+05:30

@Uday,

java.lang.Object is not allowed to be exposed as web service input/output. See the list of java data types allowed to use in web service interface here http://java.sun.com/javaee/5/docs/tutorial/doc/bnazq.html

See if this post AnyType object over webservice and Hibernate helps you in any way.

Yes, endorsed directory mechanism is just a workaround. This was required in earlier updates of Java 6, which were packaging older versions of JAX-WS. With recent updates of Java 6, this is no longer required.

2009-05-14T01:25:00.000+05:30

By the way, I tried that with my own web project so that's probably why I had this HttpServlet error. You probably won't have this error with your sample project.

Also, I forgot to mention to take of the listener class in the web.xml file.
