IncompatibleClassChangeError using JRun/Axis/Castor

[Matthew Menefee <mm...@nationsholding.com>]

I have been trying to set up a sample webservice from IBM and I am
getting an IncompatibleClassChangeError.

 

Here is the link to the sample:

 

http://www-128.ibm.com/developerworks/webservices/library/ws-castor/

 

They are on WebSphere and I am using JRun4/Eclipse.  I have my client
setup using the same methods that they did at the bottom of the example.
I have seen a few posts where they say this error is thrown because my
classpath is wrong.  I looked at my java.class.path system variables and
notice that they are different for the client and the server.  This may
be the problem, but when I changed the java.class.path variable to point
to the correct JAR files, it did not help.

 

Here is the complete trace of the error:

Does anyone have experience with this combination of products, or this
example webservice?

 

Thank you.
