Error 'Failed while installing Axis2 Web Services Core 1.1' , while setting Axis2 Web Services Facet

I am trying to implement web services using axis2, in Eclipse. (I had downloaded axis2-1.5 runtime and created environment variable for it.) I had created a dynamic web project and set the axis2 runtime successfully in Axis2 preferences.

After creating the project, I tried setting the project facet, but end up getting the following error: Failed while installing Axis2 Web Services Core 1.1

Stack shows only:NullPointerException(which is not helping me much in understanding the problem). Wat could be the problem? Without this, it's difficult to test web services using axis2.

(P.S: While creating the dynamic project, I didnt get any option to set the project facet, thus, I had to try setting the project facet, after creati开发者_StackOverflow社区ng the project. I was following the tutorial given at --> Web Services using axis2 tutorial)

Thanks

I tried to set up using Eclipse 3.6 and the error dint show up.
