Ant task wsimport fails with Java EE SDK b33d (using JDK 1.6) with NoClassDefFoundError (6527842)

Description

You may encounter a problem when running the JAX—WS tests with the JDK 1.6 included with the Java EE SDK b33d. The tests immediately abort with the following message:

[wsimport] Exception in thread "main" java.lang.NoClassDefFoundError: \
com/sun/tools/ws/WsImport

This error occurs even though the webservices-tools.jar does contain com/sun/tools/ws/WsImport.class, com/sun/tools/ws/ant/WsImport.class, and com/sun/tools/ws/ant/WsImport2.class. Moreover, the same test workspace works without problem using the 1.5.0-10 JDK.

Solution

Copy the webservices-api.jar to $JAVA_HOME/jre/lib/endorsed before running the JAX-WS tests.
