Generating WSDL results in 'Bad version number in .class file'

Hi,

I've built a small project that I would like to use as a prototype to test WSAS and more precisely the Java2WSDL tool.

Within Eclipse I'm using JDK1.5.0_06 to generate a JAR file. When uploading this JAR file in the online Java2WSDL service, I'm receiving the following error message: 'Bad version number in .class file'.

When trying the Java2WSDL tool with a locally deployed WSAS that runs with the same JDK1.5.0_06, I'm receiving the same error message.

Any help with this issue will be highly appreciated.
