Please help me to solve my problem.

Thanks,

You should check that the xml you are parsing is well formed. Also double check that the file path that you have given is correct and that the jsp can acually find that file.

I have checked the path, its fine it is detecting, but i can't understand the well formed xml, can you explain some more in detail.
But still, i am facing the same problem.

if any example on JSTL-XML, please forward me.

By well formed I mean, check that there is no blank line between the start of the file and the tag that opens with this <?xml version="1.0" . Check that you have a root element. The best idea actually is to run your xml through a validator such as this one - Xml Validator.

You say that after deployment it fails. Do you mean that you are deploying to a server? Does your code work on your local development machine and not on the server or does your code not work on your local machine either?
