Then, just do the following in your code to reference the resource. InputStream in = this.getClass().getClassLoader().getResourceAsStream(configfile); Where configfile is the complete classpath to your resource. This is nice. It works in exploded WARs, it works in WAR files, it works in JARs. No mucking about with CLASSPATH. No polluting other applications or Tomcat with spurious application - specific resources.

-Original Message- From: Christopher Schultz
(...)
Earlier somebody (I'm sorry, I already deleted the email)
suggested Tomcat returning a 308 or 309 or similar to the load
balancer to trigger a re-balance if the session is expired. I
think this is the best idea I've heard yet, solves the problem
elegantly and simply, and seems (relatively) easy to achieve
(this coming from someone who has no knowledge of the code used
by mod_jk/isapi_redirector).
I must admit that this sounds more elegant (and efficient) than my
suggested interceptor module.
Alternatively, if one wanted to avoid touching mod_jk for this,
maybe tomcat could return a 302 redirect to the starting page of
this application, if known ? (without jsessionid.jvmroute of
course).
That's definitely an idea worth pursuing: an expired session id could
return 302 *and* strip the jsessionid path parameter *and* send a
Set-Cookie JSESSIONID; expiration=0 header (which deletes the cookie).
The client would re-try and the balancer would re-balance.
Konstantin, what do you think? Obviously, this shouldn't be the
default operation of Tomcat, but perhaps a setting that could be
enabled on the session manager?
If anybody want to experiment with such a feature,
it is easy to write your own Filter or Valve that implements this.
Something like
if (request.getSession(false) == null
request.getRequestedSessionId() != null) {
response.sendRedirect(...);
return;
}
Things to be cautious
1. Different web applications may have different session ids. When a
browser sends us the session id cookie, there is no indication to what
web application it belongs.
2. I would check the value of request.getMethod().
3. I would do nothing if jvmRoute in requested session id belongs to a
different server.

The last point i.e $CATALINA_BASE is writable. I can manipulate/write files to this location. So now do you have anything more to add to your proposed solution as you suggested below 1. Please stop top-posting. 2. Put your resources in CATALINA_BASE/lib Another option is to use a VirtualClassLoader and add some random path (/etc/myawesomewebapps/) to it in all webapps. Honestly, I think there are better ways to load shared configuration than trying to share a .properties file on the disk. If the OP is able to edit files in CATALINA_BASE/lib, then editing catalina.properties and appending a fixed path to common.loader in each instance would also work. p - -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with undefined - http://www.enigmail.net/ iEYEAREIAAYFAlDEwocACgkQ9CaO5/Lv0PDc7gCfUvtH3K16UuRR/PlRzjfeMYin jbcAoMB15SHyQq/MDRnwr7Ws8CpWoY6h =E9GV -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
