java.lang.NullPointerException while invoking a service deployed in weblogic 9.2

[jijisv <ji...@gmail.com>]

I deployed small webservice into weblogic9.2 using axis2 1.4.1 (latest
release) in war form. When i invoke the service i am getting the following
error

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

But the same war file is working perfectly in tomcat.

the war file is organized as
HelloWorld.war
   -WEB-INF
       -lib 
            (contains all the axis2 libraries)
       -services
           -HelloWorldService.aar
           -services.list

Any idea why I am getting this error?? The below link says this issue is
already fixed.
