In every JSP files, you could put some information in the request to tell the servlet which JSP sent it. A request parameter for example.

I don't think there is such standard way to do this (like API methods)
I've also heard of using HTTP header called "Referer", but it is not reliable.

Actually it is available.
Look at the interface HttpServletRequest
Method getRequestURI should give you the JSP page requested by the user, though you might have to parse it from the actual servername

getRequestURI() won't tell FROM which JSP the request is coming, but TO which location it is going (the servlet itself in this case)

hi virag,
i think satou is right.....
getRequestURI()does not give the jsp page from where the request is coming....

There is nothing in the API that will tell you what JSP generated the request.
Requests don't have to be from JSPs. They could be from static HTML pages, custom, clients, other servlets, etc...

If you need to know this then the advice from Satou is your best bet.
Just add a parameter to the query string or HTML form with an identifier.

"B.Jyothi"

Please adjust your display name to have a space netween the B. and the Jyothi in order to comply with the JavaRanch naming policy.

I thought Referer is the best choice here. Can u tell me why it isn't reliable.

Web browsers tend to set the Referer header the way they want.

This would be a good technique if it was always set properly, which is not the case.

Thanks for your quick response Satou kurinosuke. I will go through it after lunch and get back to you if there is any issue.

Satou,
You are right. I misread the question as a servlet being called from within a JSP

If I want to include a link to a particular page of a website from my site but I don't want them to know about my site file path. Is there a way to suppress the referer fields. Is there any option in browsers(FireFox esp)

There was an extension called "Adaptive Referer Remover", but it is not supported by Firefox's latest version.
