Hello,

WebSphere Application Server comes with its own JAX-WS and JAXB implementations. It seems you are using a 3rd party web service library that assumes that the JAXB implementation is the JAXB RI and unconditionally casts to its implementation class.

Assuming that you have the JAXB RI bundled with your application, setting the following system property may resolve your issue:
System.setProperty("javax.xml.bind.JAXBContext", "com.sun.xml.bind.v2.ContextFactory");

This should override the JAXB implementation loaded with the JAXB RI. Alternatively you may want to consider using the JAX-WS engine included with WebSphere.
