Display Error Page in JSP

I want to display an Error Page, whenever a runtime exception occurs in the JSP.
I dont want to use -
<% page language="java" errorPage="URL"%>
But it should be done in the catch block. Something like response.sendRedirect(URL) used in servlets.
So how can it be done, if it is possible.

You don't explain why you'd rather not use the standard mechanism (highly recommened), but if you want to "roll your own" I'd:
1) Wrap the entire page in a try block
2) Create a catch clause that catches all exceptions
3) place the exception as an attribute in the request
4) forward (not redirect) to your error page
5) In your error page retrieve the exception from the request

You could also use the error page attributes in the deployment descriptor for your web app.

It is sorta covered in the JavaRanch Style Guide.
