Hi There,
I have been struggling to deploy a web-application which implements two JAX-WS endpoints,
one of which uses the provider API and the other using the POJO method.
My environment:
jbossws-metro-3.3.1
Java Version: 1.6.0.20
JBoss Version: 5.1.0.GA
OS: Ubuntu 10.04 LTS Desktop
What I do:
Implement a web-application that implements two web-service endpoints, one using the
JAX-WS provider API and the other using the POJO approach with relevant @WebService
annotation. Example code snippets:
AddNumbersImpl.java:
@ServiceMode(value=Service.Mode.PAYLOAD)
@WebServiceProvider(portName="AddNumbersPort",
serviceName="AddNumbersService",
targetNamespace=" http://duke.example.org http://duke.example.org";,
wsdlLocation="WEB-INF/wsdl/AddNumbers.wsdl")
public class AddNumbersImpl implements Provider<Source> {
.... body of class here
}
SubtractNumbersImpl.java
@WebService( serviceName = "SubtractNumbersService",
portName = "SubtractNumbersPort",
endpointInterface = "provider.server.SubtractNumbersPortType" )
public class SubtractNumbersImpl {
.... body of class here
}
I have setup web.xml with all of the relevant servlets and mappings and corresponding wsdl
files.
The SubtractNumbersImpl class has a single method called subtractNumbers which throws a
single exception.
When I deploy my web-application, I get the following stack trace:
12:35:16,621 ERROR [AbstractKernelController] Error installing to Real:

If I modify the SubtractNumbers service so that no exception is thrown then the
application deploys without any problems.
What I Expect:
The web-application should deploy without any exceptions being thrown.
Detailed Replication Steps:
Attached to this post is a zip file containing the test case I am using to replicate this
error.
Detailed steps to reproduce the problem:
Pre-requisites:
JBoss 5.1.0.GA
Sun Java 6 JDK
JAX-WS RI 2.1.7
jbossws-metro-3.3.1
1. Download the attached zip file.
2. Extract to a directory somewhere.
3. Open a terminal and move into the directory where the files were extracted.
3. Set JAXWS_HOME to the JAX-WS home.
export JAXWS_HOME=/home/jfitzpatrick/Downloads/jaxws-ri-20090416-2.1.7/
4. Build the server side code.
ant build-server-wsdl
5. Create the war file.
ant create-war
6. Copy the war file to the jboss deployment directory.
cp build/war/jaxws-provider.war /opt/jboss/jboss-5.1.0.GA/server/web/deploy
7. Start JBoss.
/opt/jboss/jboss-5.1.0.GA/bin/run.sh -c web -b 0.0.0.0
8. Observe the exception described above.
If the above steps are repeated after modifying the SubtractNumbers service so that no
exceptions are thrown, the application deploys without any errors.
To see this, simply comment out anything related to the fault/exception in the
SubtractNumbers.wsdl file and modify SubtractNumbersImpl.java so that the exception is no
longer thrown.
After doing an "ant clean" and repeating the steps above, you should observe
that the exception is no longer thrown.
My questions:
Has anyone else observed this behaviour?
Am I doing something wrong in regards to the configuration of the application?
Is it possible to deploy JAX-WS with different endpoints using different programming
models?
If anyone has any hints, ideas, or anything at all that may help it would be greatly
appreciated.
Thank you,
John Fitzpatrick
