JAX-RPC WebService not generating java array in WSDL

Question

I am currently try to generate JAX-RPC webservices from java source using the Emitter class (the same as the Java2WSDL tool) provided in Websphere. I am currently using WAS6.1 and WAS7.0 for testing. The issue is when I attempt to generate the WSDL for 'FooRequest' the ComplexType 'Foo' is missing the Bar[] from it's definition in the wsdl. When I change 'FooRequest' to return Bar[] the wsdl is generated correctly and everything is fine.

Why aren't the arrays being generated in the wsdl correctly?
Is there something which I am doing wrong?
What is the correctly way to generate the wsdl with the arrays?

Answer 1

I found a solution in case anyone finds this question in the future.

The issue was that I had previously obtained jars from an installation of old websphere 6.1:

• bootstrap.jar
• classloader.jar
• emf.jar
• ffdc.jar
• j2ee.jar
• ras.jar
• wccm_base.jar
• webserverices.jar
• wsdl4j.jar
• wsexception.jar

These jars had been passed to me via unknown other other, with no version numbers or metadata of any form. I have no idea if they are real releases of intact, but they work. Initially I was using them with the provided websphere 6.1 JRE (java 1.5), but as I was now deploying to websphere 7.0 I changed my software to use the websphere 7.0 (java 1.6). What I wasn't aware of is that the jar's and the java 1.5 release were specific to each other, so when using the java 1.6 JRE the Emitter class wouldn't fail, simply generate an incorrect wsdl.

To fix this, I just changed the software back to use the java 1.5 JRE until I have the time to correct the jar's.
