Something is wrong with Xerces. You can do one of the followings:
- add "-nv" option to the invocation of XJC. (<arg value='-nv'/>) In
this way, XJC won't use Xerces so there won't be a problem.
- if you can, overwrite xercesImpl.jar in your ant with the one in JWSDP.
- try to add xercesImpl.jar in the classpath of <taskdef>, or if it's
already in, see if excluding it will solve the problem.
