Ahh - I reread the original.
Once chain.doFilter(request,response) is called - the response is committed
and you are probably seeing IllegalStateExceptions in your logs.
You'll want something like this:
if (someCheckForAuth) {
sendRedirect( ... )
} else {
chain.doFilter(request,response)
}

Thanks for the reply.
Sorry, I guess I didn't explain how I'm applying the filter well enough.
The filter is mapped to my JSP pages.
When a user goes to the URL for the JSP page of interest they get a form
to log in. The action of the form is j_security_check. When the filter
is executed it occurs before j_security_check has been called, because
they have tried to request a JSP page that is mapped to a filter and
j_security_check is a servlet from what I understand. Filters as far as
I know are a layer above servlets and the request goes through the
filter first. That's why I need to, in my filter, call
chain.doFilter(request, response). This makes sure that j_security_check
has done its job. Then I can perform my redirect after j_security_check
has done his job.
So that's why I was using the filter. If you have any other ideas I'd
really appreciate it.
Thanks for your time and help.

You can't run a filter against j_security_check

What I'm trying to do is once a user is authorized on my server, using
FORM based authorization, I want a different servlet (other than what
the user might have originally requested) to be called before any web
page is shown to the user. The servlet helps manage a user's account and
I need to let the servlet know as soon as the user has logged in.
How can I do this?
Here's what I've tried to do writing my own filter.
example of my filter:
public void doFilter(ServletRequest request,ServletResponse
response,FilterChain chain)
{
// get authorized by j_security_check
