Hello,
Out system uses a custom class-loader but, because of the
stack-trace (below) we receive in some circumstances, I suspect that CXF
does not use our ClassLoader which should be the default by the time we
initialize CXF. We have a *CxfWebServiceServlet* which extends the
*CXFNonSpringServlet* for deploying JaxWS websevices and looking at the
source it uses the BUS to get a ClassLoader derived from the BusExtensions.
How can I ensure that our ClassLoader is always used? Can I push
our ClassLoader into the BUS before we start initializing the servlet?
Do I need to configure/create a BusExtension for this and if so, how? Do
you have any examples or can you point me at some useful documentation?
Here is the exception:
