Welcome to the Ranch.

First, a few administrative points:

1) Please take the time to choose the correct forum for your posts. This forum is for questions on JSP. This post has been moved to a more appropriate forum.

2) Please refrain from using words such as "urgent!" when posting. Your question is no more and no less important than anyone else's. In fact, by using the such terms, you you can delay or prevent useful response to your question. Please read this to find out why.
