Re: memory leaks (Tomcat 5.5.20 and JDK 1.6)
Do you monitor the memory usage over time? Is it steadily increasing? Or does it peak at one moment? Ronald.

Concurrent threads per session (limit = 3 ?)
Hi, if I am using the firefox browser to send requests to a tomcat servlet all new browser tabs belonging to the same session. I am running AJAX requests which block the servlet request thread 60 seconds waiting for a certain event. This leads to the uncomfortable behavior that the fourth request to the same session blocks until one of the other requests return/finishes. It seems to me that the tomcat (v 5.5) limits the number of threads per session to 3. I would like to increase this number to prevent blocking of further requests. How can I adjust this setting ?

Re: Concurrent threads per session (limit = 3 ?)
I doubt tomcat limits the number of Threads per session. To get the session id, tomcat need to parse the request, but this parsing occurs in the Http-Thread that handle that network connection. Having that HTTP-thread wait would be, for tomcat, wasting a Thread. On the other hand, it's common courtesy of browser to limit the number of connection per server to a reasonable amount (4 or 8 generally). AJAX request can't escape that limit :) Since you are using firefox, i suggest you take a look at about:config - filter=network.http You might find there useful configuration helps.

Re: Frequent SEVERE: Unable to receive message through TCP channel messages
You configured a 3 seconds timeout for your heartbeat. If a node doesn't receive a heartbeat packet for 3 seconds, it assumes the other node is dead and closes the incoming replication connection. If the other node is not really dead, it will try to use this replication connection which will not work any more. Why could this happen: one possible reason are GC pauses. If you've got longer GC pauses, than your membership heartbeat timeout, then you run into such problems. During normal operations you should not observe any memberDisappeared messages. They should only show up, ehen you stop a node or it crashes, or you've got serious network problems with impact on the multicast heartbeat packets. If you decide to increase the membership timeout (which sounds like a good idea), keep in mind, that you need to wait the given time between stopping and restarting a node.

undesirable session timeout behaviour
For reasons all my own, I want the timeout period to be quite short - essentially if a (human) user sits around doing nothing for more than 5 minutes, I want to timeout the session. I have configured tomcat to do this, and it works fine. Except. If the user initiates an activity (ok - I'll admit - it's a download) which takes longer than 5 minutes, the session gets timed out every time, since tomcat doesn't monitor activity in general for timeouts; tomcat just monitors user requests. I thought of setting the timeout to some large value at the start of a download, but that would require estimating bandwidth ahead of time (to estimate a good value for timeout). It would be more appealing to have download traffic reset the timeout clock, but I'm open to other insights. Has any body else had this problem, and (even better) created a solution?

NoSuchMethod shutdown error
I just upgraded from 5.5.9 to 5.5.23, and now, when I shut down tomcat, I get these errors. Any idea whats going on? Looks like I have an out of date jar file on the classpath - but as far as I know, these are tomcat only jar files...

Re: Proxy Server
The stock answer is to setup mod_proxy under Apache and use Apache to
front-end load all your requests (details located here)
http://tomcat.apache.org/tomcat-5.5-doc/proxy-howto.html
Note that If you have any appreciable amount of static content (watch your
jmeter perf nosedive) then you will want to look into implementing mod_jk
If you dont want to go thru the complexity of installing yet another system
then you can use the tried and true request.getHeader as in
String Referer_value = request.getHeader(HTTP_REFERER)
and redirect the request according to some criteria
if Referer_value == localhost (this request is for my server so process
normally)
else
{
String serverURL = request.getParameter(serverURL);
String deployuri = request.getParameter(deployuri);
String redirectURL = serverURL + deployuri;
response.sendRedirect(redirectURL);
}
If you've installed Tomcat the example code to retrieve headers is located
at
http://YourComputer:8080/servlets-examples/reqheaders.html

Subject: Proxy Server
Hi,
I am using a Tomcat 5.5.9 server (only for development) on my local pc,
within a company network that is using a proxy server. Problem: My
application does http requests to a server were a proxy is required, as
well as requests to an
IP adress were no proxy is required / allowed. I added these 2 lines to my
catalina.properties file:
http.proxyPort=MYPROXY_PORT
http.proxyHost= MYPROXY_URL
If I add these lines, the service that requires the proxy works, however
the other service does not work - and vice versa.
Is there a way to configure Tomcat so that I may use a proxy, but exlude
certain URLS, just like you can do in a browser?
Thanks in advance,
Marcus

multiple comet requests
How do you send multiple requests to the same comet servlet?
Sending multiple chunks of a single request is fine. My problem occurs
after the client ends the chunked transaction by sending 0CRLFCRLF to the
server. The comet servlet correctly registers the END event.
But then the client subsequently tries to initiate a new chunked request by
sending new http headers and a new chunk. The comet servlet receives a
BEGIN event, immediately followed by an END event. A READ event is never
generated for the new chunk. No ERROR events are registered either.
Sequence:
1st request
BEGIN
READ
END
2nd request
BEGIN
END - why an END event and not a READ?
Below are my test client and test comet servlet. Any thoughts on what I'm
doing wrong?
(I apologize in advance if this is a lack of understanding of http on my
part. I have looked at the specs and tried to follow the rules but am still
running into problems.)
Thanks,
Peter

Removing the port identifier
Is there a way to remove the port number from a https request where the original url looks something like this: https://host_name:8443/ The approach to change the server.xml file (where the connector port is changed from 8443 to 443) is not practical for us. When this is done, Tomcat requires the root user to run. We consider this a security risk. We have considered a port forwarder, but we are unclear whether to install this on the Tomcat server or router. In any event, we are not at all sure this is the best approach. Any advice will be appreciated. Our operating system is Mac OS X.

Re: multiple comet requests
turns out that if the request is comet, the recycling of the
input/output filter is not happening.
I have fixed this,
you can try the tomcat-coyote.jar from
http://people.apache.org/~fhanik/tomcat/tomcat-coyote.jar

My problem is this: One of my pages with an apostrophe was not displaying properly, so I added to my jsp: %@ page contentType=text/html; charset=UTF-8% When I did that my content displayed correctly, but on form submission it got corrupted. You can view the problem here: http://b.tupari.net/ One page displays correctly, but on submit the value gets mangled. The other page doesn't display correctly, but if you cut and paste into the form from the first page the apostrophe does come out correctly on submit. This happens in both firefox and konqueror. So who is to blame here? The web browsers? Tomcat?

Do I get the box, if I can write a servlet and describe a procedure by
which a Firefox user can produce the exception when calling my servlet?
I think that something like (haven't actually tried it myself, mostly
because I have servers with infinite timeouts):
protected void doGet(HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException {
response.setContentType(text/plain);
PrintWriter out = response.getWriter();
out.println(Hello World);
out.flush();
try {
Thread.sleep(timeout); // timeout is = the configured timeout
on Apache
} catch(InterruptedException iex) {
//ignore
}
}
should work. If anyone has a more interesting example, I'd love to see it
:).

Have you noticed if this affects IE users and Firefox users equally? I
ask because there's a known issue (that I've never seen an actual answer
to) where IE causes these exceptions frequently with no ill effect to
anything (other than the overhead of handling the exception in the VM on
the server). I'd bet a box of donuts that it only happens for IE users.
Yes, it should have no ill effects, since it is happening where Tomcat is
telling Apache that it is done with the request, so Apache can reuse it for
somebody else.

Re: NoSuchMethod shutdown error
also, I noticed that you have some Failed Shutdown of Apache Portable Runtime errors, if you want to make that message go away grab the APR native library for your platform and drop it into %JAVA_HOME%/bin symptoms: on startup something like the following gets printed out: INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path and on shutdown- INFO: Failed shutdown of Apache Portable Runtime Basically, tomcat looks for a native library that lets it do funky stuff related to performance. In development we don't usually care about performance, but if you want to get rid of those messages, then the easiest way is to drop the tomcat native dll onto the system path, the best place being %JAVA_HOME%/bin read about the APR: http://tomcat.apache.org/tomcat-5.5-doc/apr.html I downloaded it here: http://apr.apache.org/download.cgi -- * Matthew Kerle ** IT Consultant* ** * Canberra, Australia* Mobile: +61404 096 863 Email: mailto:[EMAIL PROTECTED] Matthew Kerle mailto:[EMAIL PROTECTED] Web: Matthew Kerle http://threebrightlights.blogspot.com/ Dan Armbrust wrote: When I was upgrading tomcat, I had a jar file hang around in source control that shouldn't have been there.

I have fixed this,
you can try the tomcat-coyote.jar from

Peter Warren wrote:
How do you send multiple requests to the same comet servlet?
Sending multiple chunks of a single request is fine. My problem occurs
after the client ends the chunked transaction by sending 0CRLFCRLF to the
server. The comet servlet correctly registers the END event.
But then the client subsequently tries to initiate a new chunked request by
sending new http headers and a new chunk. The comet servlet receives a
BEGIN event, immediately followed by an END event. A READ event is never
generated for the new chunk. No ERROR events are registered either.
Sequence:
1st request
BEGIN
READ
END
2nd request
BEGIN
END - why an END event and not a READ?
Below are my test client and test comet servlet. Any thoughts on what I'm
doing wrong?
(I apologize in advance if this is a lack of understanding of http on my
part. I have looked at the specs and tried to follow the rules but am still
running into problems.)
Thanks,

Re: Removing the port identifier
the only way to get rid of the port number is to have something listening on :443 (that's the way browsers are, sorry), and then hand requests over to tomcat, so to get what you want something will have to bind to :443 at some point, requiring root privs. What you want is something that will bind to the port as a privileged user and subsequently drop priv's to a limited user. the Apache web server is excellent for this kind of thing. The easiest way to do this would be with apache sitting in front of tomcat with either mod_jk2 or forwarding requests with mod_rewrite. It doesn't really matter where the port forwarder sits, but usually you want to align with existing IT infrastructure and use an existing internal/internet web server to redirect requests to your app. If your company already has apache then this is a cinch, otherwise you'll have to figure out how to reverse-proxy with the web server du jour...

Re: Removing the port identifier
well spotted, I apologise! the correct connector is mod_jk (1.2). As for running tomcat on low ports, it depends on deployment. if your app needs to sit within a larger site then it makes sense, but if it's standalone then using another method to run on a low port would be a better solution. If the application has a lot of static content then it makes good performance sense to put something in front of it, either apache or squid. but that's probably not an issue in this case...;-p ! -- * Matthew Kerle ** IT Consultant* ** * Canberra, Australia* Mobile: +61404 096 863 Email: mailto:[EMAIL PROTECTED] Matthew Kerle mailto:[EMAIL PROTECTED] Web: Matthew Kerle http://threebrightlights.blogspot.com/ Caldarale, Charles R wrote: From: Matthew Kerle [mailto:[EMAIL PROTECTED] Subject: Re: Removing the port identifier the Apache web server is excellent for this kind of thing.

Actually, that's not really true anymore. The current Tomcat without APR is almost as fast as httpd for delivering non-SSL static content, and with APR it's pretty much the same for both non-SSL and SSL traffic (since it's the same code). There are reasons to use httpd in front of Tomcat, but delivering static content isn't one of them. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
