As far as I know the threads from the connector are shared between webapps.
So how would Tomcat know which objects in the threadlocals are from which

Or should Tomcat destroy all threadlocals of webapp A if I reload webapp B?

You don't give much details about your problems. But I think you have some
long-living big datastructures which are hold in the session, so you can't
cluster your sessions.
You could redesign your application to make it more scalable. In the end that
is your problem, so it's the solution
2 Instances don't compete for locking between threads. So possibly your
application depends a lot on locking?

Hi,
I'm running a webapp which use jaf (java activation framework) for javamail. In
the past it was possible to deploy different versions of our webapp in

I use -Dsun.net.inetaddr.ttl=3600 and left the negative.ttl as default (10?).
Our network runs its own caching dns server. Never had any trouble with it.

Fix for step 3. Don't wait for Tomcat to detect changes. See
http://tomcat.apache.org/tomcat-6.0-doc/manager-howto.html or use
org.apache.catalina.ant.ReloadTask (which uses the manager). My compile command
automaticly calls this after a succesful compile.
Another tip: test business logic
Hi,
At the company I work we are doing this for a couple of years already with
Tomcat 4, 5 and now 6. Works very well. And makes threaddumps more easy to read.
A filter is very ease to make.
public class ThreadNameFilter implements javax.servlet.Filter {
public void doFilter(ServletRequest
As with the tips about usage of char in the switch you can also test using a
char in the if ... else.
if (myChr.length() != 1) {
throw new RuntimeException(invalid length);
}
char ch = myChr.charAt(0);
if (ch == 'c') {
p += 1;
} else if (ch == 'r') {
p += 2;
} ...
Should make a difference
client --- tomcatServer --- notificationServer
1. client sends request to tomcatServer
2. tomcatServer calls notificationServer.waitForEvent() (this can wait forever
if there is no event)
3. tomcatServer get event and send response to the client.

Hi,
Make sure you compile everything with Java 1.5 or javac -target 1.5. That wil
run in java 1.5 and 1.6.

Hi all,
I failed at searching for this, even though I know it's been answered:
Setting: Tomcat 6.0_20; Mac OS X 10.5.7;
You can create a filter or run on separate Tomcat instances.
NB: You are not solving the cause, but the effect. You don't have enough
threads or cpu-power to handle the total load.
