Thanks, Robert.
After setting the ServiceTCCL parameter to "service", I ran into the
following error in the following call during AxisServlet.doPost()
AbstractMessageReceiver.getTheImplementationObject.
The DependencyManager.initServiceClass call in it throw
this exception:
Jan 31, 2007 2:05:22 PM
org.apache.axis2.transport.http.AxisServlet doPost
SEVERE: java.lang.ExceptionInInitializerError
I noticed the following:
1. The serviceimpl class was loaded ok but initialization failed. The class
loader is DeploymentClassLoader. Is this correct?
2. From eclipse debugging, I was not able to step into
DependencyManager.initServiceClass() call. The thread stays
in "stepping" status w/o call stack, not the "suspended" status. Any idea
what this "stepping" state indicate?
Any suggestion on what I else I can try?
Thanks,
-Bo
