Subject: Filter mapping question
Hi,
I have a servlet and a filter I want to be run when that servlet
is accessed. However, the servlet is never accessed directly via
the browser. Rather, it's embedded in a frameset and launched
using something like this:
a href=javascript:void(0);
onClick=thatframe.src='http://myhost/mycontext/myservlet'; return
true;
click here
/a
So in my web.xml, I have:
filter
filter-namemyFilter/filter-name
filter-classmyFilterClass/filter-class
/filter-name
filter-mapping
filter-namemyFilter/filter-name
servlet-namemyServlet/servlet-name
/filter-mapping
servlet
servlet-namemyServlet/servlet-name
servlet-classmyServletClass/servlet-class
/servlet
I assume you also have a servlet mapping, right? It would need to look
like this:
servlet-mapping
servlet-namemyServlet/servlet-name
url-pattern/myservlet/url-pattern
/servlet-mapping
The problem is, tomcat never calls doFilter() for my filter when that
servlet is called. The filter gets initialized appropriately (I have
logging comments on the filter's init(), doFilter(), destroy() methods).
If I go to http://myhost/mycontext/myservlet myself, the filter does
get called, so I know it has to do with the calling mechanism,
filter-mapping,
or something along these lines.
Thanks in advance, and sorry for the long post,
Tomcat has no way to know whether the request came from the location line
of the browser or via JavaScript -- so that's not the cause of the
problem. You can look at the access log (in the logs directory) to see
what URI is really being requested when you do it manually, and when the
Javascript function calls it, to ensure that they are really identical.
One other thing to check is that your servlet mapping is really for
/myservlet and not for /myServlet. URLs are case sensitive, so this
would cause a mismatch.
