What version of axis2 are you using? You don't seem to be using the
latest stable version 1.3, as line 58 is:
58 if (servletConfigParam == null) {
Furthermore, have you read this?
http://ws.apache.org/axis2/1_3/app_server.html
Your problem seems like its classloader related, ie, its possible by
following the instructions in the above link you can solve the
problem. While its been a while since I've used weblogic, some simple
googling show people have been running spring / axis2 / weblogic
successfully.
If all else fails, while I'm hesitant to patch axis2 for specific app
servers and would probably verify the problem myself first that
there's absolutely no other way - the first step would be getting your
code to compile with svn or a nightly:
http://people.apache.org/dist/axis2/nightly/
http://ws.apache.org/axis2/svn.html
HTH,
