RE: Exception after upgrading to Axis2 1.7.3

Use apache-cxf. It is more widely used and has better and legitimate documentation.
AXIS2 says you can use XmlBeans for databinding. When you goto the XmlBeans website they say the project is retired!

Subject: Exception after upgrading to Axis2 1.7.3

I was tasked out with upgrading our legacy Axis2 implemtation from 1.5.6  to 1.7.3.

I have worked through all the various library and compilation changes and it seems to be compiling and packaging as expected.

However, when I attempt to start the app, I receive the following:

I'm at a loss at to what is causing this problem.

Can anyone point me to a likely cause of this error?


Thanks,
