please help me to resolve this issue

Welcome to the JavaRanch, Nihil!

There's nothing about JSF in what you listed, so I'm moving your question over to where the XML experts live. They're more likely to give you a useful answer.

Incidentally, there's a "Code" button in the Ranch message editor GUI. You can use that to generate tags to wrap your java code and XML samples and it will make them more readable.
