Subject RE: ClassCastException: com.ibm.xml.xlxp2.jaxb.JAXBContextImpl incompatible with com.sun.xml.bind.api.JAXBRIContext
Date Fri, 10 Oct 2014 14:50:31 GMT
Hi Robert,

There is no correction as such. The WebSphere configuration has be 
removed and not corrected.
Try setting the the classloader settings in WebSphere to parent-last. 
That should work with 0.9.0 and 0.10.0.
I would recommend upgrading to 0.12.0 because of other improvements.
