Arun,

This (again) looks like an error in your plugin code. Please use a debugger and provide more information if you want help.

Besides, it looks releated to https://community.jboss.org/message/809317#809317 which you just posted. We already asked you to stop duplicate posting.

Hi Thomas,

    It is happended due to my lack of knowledge in RHQ. I though these are different problems.

Besides, it looks releated to https://community.jboss.org/message/809317#809317 which you just posted. We already asked you to stop duplicate posting.

And of course, The above link is not at all related to this post. This post is for my another plugin. I am learning to write plugin for RHQ. That is why I am creating many plugins each day in different dimensions for coding practise.

Can you share me where i am commiting mistake in plugin.

And Very Sorry If you still feeling that I am duplicating. I swear that I will not do it anymore.

Hi All,

   Fixed this error.

   It is based on the dataType mismatch in plugin descriptor and my java code.
