JBossTS + WS-TX on JBoss 4.0.3SP1

[ruthbd]

I am trying to get a simple test with JBossTS and WS-TX running in my local JBoss environment. I am certain I have not understood all the relevant documentation, but I am not getting any further.

I have a simple "echo" web service using the jbossws4ee stack (4.0.3SP1 default) - my webservices.xml looks like this:

<webservices
 xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://www.ibm.com/webservices/xsd/j2ee_web_services_1_1.xsd"
 version="1.1">

 <webservice-description>
 <webservice-description-name>HelloWorldServiceJSE</webservice-description-name>
 <wsdl-file>WEB-INF/wsdl/HelloWorld.wsdl</wsdl-file>
 <jaxrpc-mapping-file>WEB-INF/jaxrpc-mapping.xml</jaxrpc-mapping-file>
 <port-component>
 <port-component-name>PortComponent</port-component-name>
 <wsdl-port>HelloWorldInterfacePort</wsdl-port>
 <service-endpoint-interface>org.jboss.samples.HelloWorldInterface</service-endpoint-interface>
 <service-impl-bean>
 <servlet-link>HelloWorldService</servlet-link>
 </service-impl-bean>
 <handler>
 <handler-name>WSTContextProcessor</handler-name>
 <handler-class>com.arjuna.mw.wst.service.JaxRPCHeaderContextProcessor</handler-class>
 </handler>
 </port-component>
 </webservice-description>
</webservices>

This seems to deploy fine, but when I invoke the service, I get a ClassCastException thrown from org.jboss.webservice.handler.HandlerChainBaseImpl#addHandlersToChain (line 88). Taking the node out of webservices.xml deploys & invokes fine.

Here's the "root" exception (the full trace is huge):

Caused by: java.lang.ClassCastException: com.arjuna.mw.wst.service.JaxRPCHeaderContextProcessor
at org.jboss.webservice.handler.HandlerChainBaseImpl.addHandlersToChain(HandlerChainBaseImpl.java:88)

Any ideas? I wish I could jump to JBoss 4.0.5GA, but my hands are tied at the moment.

Cheers,
Brice

That line attempts to cast the JaxRPCHeaderContextProcessor to the Handler interface.

Given that this class implements the interface it would suggest that you have more than one copy of the interface being loaded.

So, different copies/versions of the jaxrpc .jar files?

So, for the server stubs, I believe I need the jaxrpc-*.jar (api, impl, spi) - but, a search through JBOSS_HOME yields jboss-jaxrpc.jar ... so, what do I need/not need?

Yes, that would be my guess. You can compile against external jaxrpc jars but should not include them in the deployment.

Ah, OK - I'll take the jaxrpc-*.jar files out of WEB-INF/lib.

Sweet, that did it. All I have in WEB-INF/lib now is wstx.jar - seems to work (i.e. no exceptions).
