Can't find classes in jar files in WEB-INF (was: Recurring (looping?) error messages)
When I put my webapp.jar file in the WEB-INF directory, it doesn't find the app. When I exploded it into the classes directory, and associated subdirectories, they are found fine, but I get this problem (the one below). This, it turns out, is triggered by the fact I have the webapp.jar file in the lib directory and all the classes unpacked in the classes directory (both under WEB-INF, of course). Getting rid of the webapp.jar file in the lib directory solves the problem below, but now tomcat won't use that the jar file in the lib directory, even though when it's unpacked in the classes directory, he seems perfectly happy. Is there some magic I need for tomcat to use .jar files in the WEB-INF/lib directory, like an entry in web.xml or server.xml?

Re: Tomcat ssl/https: error 302 when accessing servlet with https
All, Well, the solutions was rather simple. Since I had to re-install Fedora Core 5, I neglected to open port 443 in the FC firewall. Once opened, all worked just fine. Sorry for spinning everyone's wheels, but I guess there's a lesson in here somewhere (probably something to do with Occam). Again, thanks to all who replied to my support request. Greg. Caldarale, Charles R wrote: From: Greg Brownell [mailto:[EMAIL PROTECTED] Subject: Re: Tomcat ssl/https: error 302 when accessing servlet with https As for auth-constraint, users never had to authenticate before accessing the servlet(s). Yes, you're right - I just verified that lack of any auth-constraint, as opposed to an auth-constraint with no roles, allows access to all. Reading the original question more closely, the 302 is not an error - it's just a redirect from the server supplying a different URL for the browser to try. This happens, for example, if you attempt access via HTTP, and the server redirects to HTTPS. Since this timeout appeared only after you changed certificates, have you tried going back to the prior one? - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: IOException writing to /usr/share/tomcat5/conf/tomcat-users.xml.new
if you're not writing within the $CATALINA_HOME folder you'll need to assign
write permissions for TOMCAT webapps to access the folder
e.g.
grant {
permission java.io.FilePermission /opt/jdk1.5.0_06/jre/lib/wsdl.properties,
read,write,execute;
}

Re: [OT] Weird Exception thrown on startup (how to resolve?)
a good practice would be to handle the IOException in code
//lets assume foo was initialised to a Foo class and supposedly serialised
earlier (possibly in an earlier (init()) method)
String result;
try
{
result = foo.getNewMethod()
}
catch(IOException ioe)
{
System.out.println(foo is corrupt will reconstruct..)
foo = new Foo();
result = foo.getNewMethod();
}

Re: Performance tuning parameters
Alan, Thanks for the definitions. This is good info! -j On 2/16/07, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: J. This is what I've learnt in the last couple of months: - maxThreads The maximum number of http worker threads that tomcat will create. This is the limit of the number of concurrent http requests that the server can be servicing at any given moment. If the thread is waiting for a database or webservice call , then the thread is just blocked but it is still part of the maxThreads count (750 in your example). Tomcat will create more threads to do the other stuff that needs to be done. - minSpareThreads The number of new threads that tomcat will start when the threadpool has become full.We have the number set down to 20 because it appears that the request that triggered the increase waits for all the threads to be created (i.e. the pool to get the new stock of threads), before the request is handed to one of those threads. - maxSpareThreads When the number of threads that have nothing to do in the threadpool gets to this number, tomcat will start removing threads from the threadpool, and killing them. - acceptCount This is the number of TCP connections that will be accepted even though there may not be a Thread immediately available to service them. This means that in your example you could have 850 incoming request at any momemt, Request number 851 will be refused (received a connection refused). We have the acceptCount set to half of the number of threads, so that there can be a big pile up of work, if our database suddenly gets a hickup.

I am sorry if this is a trivial questions, but I have worked with cases that people have no load balancer and connections are just killing them. Now, if you do not have a load balancer you might consider NetScaler, it might lower your number of connections considerably. Andrew Pliszka j r wrote: I am gleaning from your comments that MaxThreads is the only thing to tweak. Yes I do really have a connection issue. I have millions and millions of connection requests on a very small pool of servers. The app has been tuned constantly over years. I am either bound to buy more servers or tweak tomcat to get more throughput. In reality, I probably need to do both. On a large pageview day, we will overflow the 750 MaxThreads. This is noticed by the MaxThreads limit being exceeded error message. We have tweaked all pieces of the tomcat config. I was hoping a post here could get more explanation of the parameters. We have our experience to fall back on, but I was hoping for more. If MaxThreads is the main thing to tweak, we will continue doing so. There is a limit to this though. You should create the funnel for customer requests (webserver limits, mod_jk limits, and tomcat limits). Exploding MaxThreads to a large number just to be large does not seem to fit with having an acceptCount value or the funnel that should be created.

If you REALLY have an out of connection problem, increase Max Threads to 1, but I don't think that will really help you. The problem is usually that each individual request takes tooo long, which again, points back to your application - There isn't that much to tweak in tomcat. Once you have configured your application, then you can start looking at the kernel - but these only bring small % improvements.

I never said that it was serving slow. It hits connection limits which means that the app will not serve any more traffic until connections clear. If a box definitely has more capacity (dual core, dual procs), then my best guess is that tomcat is not tuned perfectly to allow the max amount of connections in. We have raised MaxThreads in the past to allow more connections in. This works, but surely other knobs are important to be tweaked. I am looking for good definitions and/or best practices on which knobs to tweak to allow the max connections in before exhausting the jvm native memory allocation or cpu on the box.
