I had added the Axis2_Codegen_Wizard_1.3.0,Axis2_Service_Archiver_1.3.0 to eclipse plugin. On clicking finish button, after I go through all the steps which include specifying wsdl file path and output path, I a pop up with following error.

An error occurred while completing the process

java.lang.reflect.invocationtargetexception

Any idea ?

Here is an update. I used the 'eclipse - console' from my command prompt and the error it shows is
java.lang.noclassdeffounderror: edu\emory\mathcs\backport\java\util\concurrent\ConcurrentHashMap

I am using the backport-util-concurrent-3.1-osgi. jar,backport-util-concurrent-3.1. jar in the library. Even then am getting this error. When I searched through the path given above(in the above mentioned jars), the ConcurrentHashMap.class does exist.

No idea why the error is caused.

Well, the problem was solved on upgrading to Eclipse IDE 3.6.
