I don't think JDK 1.6.0_04 is the reason for this problem. JDK 1.6.0_04
already has JAXB 2.1 API and if your standalone JAXB impl is in the
classpath, you don't need to use endorsed mechansim with JDK 6u4.
Standalone JAXB RI is tested to work with latest JDK 6 update releases.
How are you defining your wsimport ant task in your project? Are you
using fork option for wsimport?
thanks,
