JMS Web Services in latest OC4J 9.0.3

Question

Just trying out the JMS Web services in OC4J 9.0.3 just released today. Using Ant 1.5 and updated the build.xml file as directed. Using JDK 1.3.02.
Trying the JMS Web Service demo #2 based on JMS on top of Oracle AQ. Everything works fine - queues set up fine, OC4J configured nicely, and the following steps of the build work fine: clean, setup, compile, mdbjar ...
But when I get to the assemble step it crashes with the following error:
assemble:
[echo] assembling Web Services EAR. ..
[java] Please wait ...

What is interesting is the WSDL and proxy appear to have been generated successfully. Even the jmsws2.ear and mdb_service2.jar files appear generated ok. But the web.xml is missing so perhaps this is where it died. Any clues as to what might be wrong ... are changes required in the config.xml file driving the WebServicesAssembly tool?
Thanks for any help.

Answer 1

Went a little further ... given the assembly error seemed to occur on the last step creating the proxy.jar file, I simply skipped over it and did the deployment (changed the build.xml to continue assembly upon failure). This seemed reasonable as all the ear and war files where there; the only missing piece appeared to be the proxy.jar.
The deployment of the service was successful and I downloaded the proxy.jar file from the OC4J instance which in turn allowed me to compile the Web service client. Things were looking up here.
However, when I ran the service I got an error indicating the wrong number of arguments to the underlying queues. Given it got through to the database, I assume my configuration is set up correctly but it is a little hard to debug from here. Here is the error I got (note tried on 9.0.1 and 9.0.2 database):

The two oc4j configuration files requiring editing datasources.xml and application.xml are included below. Datasources was straightforward; I wasn't quite clear about the <resource-provider> entry in application.xml as it wasn't clear if this is a top level element or what. See the very end of this post to see where I put it.

Any suggestions? Wait for production?
