It will, but the way the Windows installer is written at the moment, the installer requires a 64-bit JVM on 64-bit operating systems. This requirement isn't necessary and the installer could be improved to handle this better.

RE: Tomcat scalability setting - need help please
Dear Leon Let me answer your question by the number of the questions: 1. My threadpool settings: are you talking about the java threadpool or the tomcat server setting for the thread pool. If this is tomcat, I am sorry I think I set it to standard from installation. I did not change any tomcat standard settings except for the -xmx and -xms stuff. As for java, the DB thread pool is set for 200 connections at once. What I meant by slows down is that user clicks on a simple form view function that usually takes less dan a blink of an eye to open, now the application just not responding. The browser just keep loading and the load animation for IE keeps spinning, but does not return the appropriate response page and sometimes it just died (blank). When I check the tomcat logs nothing went wrong. This happens if a user run one of the heavy duty app and someone else run another app (even simple ones). Regarding multiple tomcat machine I am trying to avoid it because I would have to rewrite the entire software or get an QOS machine to disperse the weight. 2. For number 2, I did the warning for user to wait and not to close the browser before it is finished. But, a lot of them just don't even bother to read the warning and keep closing it. I was wondering if there is an API for monitoring dead users out there. Or I can always create a new API to monitor user activities by planting an applet on the user site that will keep pinging to the server and if the ping died, that means the user closed the browser. Is this wise? Or I can try to see The java Concurency thing that you mentioned below.

RE: Tomcat scalability setting - need help please
Hi Pid My task is a web-based ERP application. It uses database and the number of user connection to it is up to 200 users. I use MySQL for the database. I apply the -xmx1024m and -xms1024m because I once got a message about Java Heap Out Of Space, so I searched the web and some people suggested that settings and it worked... for a while. Now that the amount of data is increased and the user using the app increased as well, lagging has been happening. The settings above I set it in the Tomcat Service monitor. And yes, I also set tomcat as service. It's running 32 Bit windows 2003 only With 8GB Ram. The tomcat version is 6.0.14. I am not assuming either tomcat is the problem or my software. I am merely trying to find a way out and I have exhausted my resources to make the software as fast as possible. Tomcat setting is the only thing that I have not explore extensively since I am not as expert as you guys. Maybe I can learn a tip or two to make things better. By the way the number of data that is being processed by the heavy app is in millions of rows. I ran the SQL directly to the mysql server and it worked ok (within minutes and not freezing the server). Meanwhile, when the query is being run via tomcat, then it will freeze the server as well. It does not kill the server, just consume all the server resources, but eventually will come back to normal after two hours with the result.

Tomcat with NIO???

RE: Tomcat does not honor acceptCount configuration variable
From: Timir Hazarika [mailto:timir.hazar...@gmail.com] Subject: Tomcat does not honor acceptCount configuration variable What is the best way to limit connections in tomcat, if there is one ? Somewhat depends on what you think connection means. If you're actually referring to sessions, you'll have to limit that based on logic in your webapp, usually implemented in an HttpSessionListener (read the servlet spec for how to configure one). I have tried acceptCount The acceptCount is the value used by the platform's TCP/IP stack to limit the number of HTTP connection requests held in a queue. The number actually in the queue at any given time is invisible to Tomcat. maxThreads The maxThreads settings limits the number of requests that Tomcat will handle concurrently. For the JIO Connector, that's also the number of active HTTP connections using keep-alive, since there's a thread dedicated to each active connection. For the NIO and APR connectors, threads are not dedicated to HTTP connections, so it's purely the concurrent request limit. explicit executor This is simply a way of sharing a thread pool across multiple Connector elements, nothing more. So what exactly are you trying to limit? - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Junit and Tomcat
Dear All, I've been going round in circles for about two weeks now trying to work out how to use Junit with Tomcat effectively. Any help or advice about how to do this would be very much appreciated. The main problems are probably well known, but what does everyone else do about it? But the odd part is that there's very little about all this to be found on the internet. 1) I get my datasources from Tomcat, so I can't get to them from Junit 2) I get the path in the file system to my Tomcat folder from Tomcat, which is very convenient, but in consequence every path to a file in my code depends on this. For example I'm trying to test a method which uses a value from a property file, but I can't do it, because the Junit test can't find the property file path. Searching the web again and again has brought up very little except Cactus. Cactus on paper looks like a good idea, but Cactus has a very low profile in google searches, which possibly means it is not used much. But more important is the fact that it doesn't appear to be supported any more since it uses an old version of Junit without annotations, and I'm already used to the new version. I could probably code round the problem: but the recoding - just so that I can test things effectively - will be enormous. Thanks for any help with this. Regards, Malcolm Warren
Tomcat 6.0.24 requires me to log on twice
Hi, I am having a problem with Tomcat - if I log on to a page which contains a restricted resource, it shows me the page (and any unrestricted images, etc), but doesn't show the restricted resource (I believe tomcat thinks the user is not authenticated as sends the 403 page, judging by the 3478b size of the request). When I move on to another page (or reload the same page) I am sent to the logon screen again, after I logon from here everything works as it should. The protected resource is some javascript, it is dynamically created as it varies from user to user. This happens on Tomcat 6.0.24 and 6.0.26, but not 6.0.20, which makes me think it is related to change 45255 (Provide protection against session fixation by changing session ID automatically on authentication.), in the dev environment tomcat is running on windows XP. Session tracking is done by cookie, not URL rewriting. Below is a(n abridged) snapshot of the access log, the last field is the cookie sent by the browser dataservlet1, dataservlet2 and javascriptservlet are restricted to logged on users, nothing under /frontend has any security constraints. The sequence of events, from the browser end is (1) A request is made to dataservlet1 (2) The user logs in (and tomcat rewrites the cookie) (3) Is forwarded to the dataservlet1 page, frontend resources are displayed, but the javascriptservlet is not, as it has been requested with the old cookie (this happens on ie and firefox, so doesn't appear to be a browser issue), the apparent attempt to logon for the javascriptservlet also throws another cookie into the mix (4) Another page is requested (5) The user is sent to the login page (6) They log in again (getting a third cookie), and from this point everything is ok #Fields: c-dns x-H(remoteUser) date time x-H(protocol) cs-method cs-uri sc-status bytes x-H(requestedSessionId) #Version: 2.0 #Software: Apache Tomcat/6.0.26 (1) localhost - 2010-04-08 12:25:33 'HTTP/1.1' GET /dataservlet1?timestamp=1205168884309 200 3478 - localhost - 2010-04-08 12:25:33 'HTTP/1.1' GET /frontend/images/image1.gif 200 125 '6A193109AA' (2) localhost - 2010-04-08 12:25:42 'HTTP/1.1' POST /j_security_check 302 - '6A193109AA' localhost - 2010-04-08 12:25:42 'HTTP/1.1' POST /j_security_check 302 - '6A193109AA' (3) localhost 'user75' 2010-04-08 12:25:46 'HTTP/1.1' GET /dataservlet1?timestamp=1205168884309 200 22904 '949F3A1AED' localhost - 2010-04-08 12:25:46 'HTTP/1.1' GET /frontend/includes/functions.js 200 917 '6A193109AA' localhost - 2010-04-08 12:25:46 'HTTP/1.1' GET /javascriptservlet?request=common.js 200 3478 '6A193109AA' localhost - 2010-04-08 12:25:50 'HTTP/1.1' GET /frontend/images/global/logo.gif 200 2393 'DE52CCEEE3' (4) localhost - 2010-04-08 12:26:04 'HTTP/1.1' GET /dataservlet2?timestamp=1270729564199 200 3478 'DE52CCEEE3' localhost - 2010-04-08 12:26:04 'HTTP/1.1' GET /frontend/images/image2.gif 200 125 'DE52CCEEE3' (5) localhost - 2010-04-08 12:26:07 'HTTP/1.1' POST /j_security_check 302 - 'DE52CCEEE3' localhost - 2010-04-08 12:26:07 'HTTP/1.1' POST /j_security_check 302 - 'DE52CCEEE3' (6) localhost 'user75' 2010-04-08 12:26:09 'HTTP/1.1' GET /frontend/global.css 200 3032 'D2092750B2' localhost 'user75' 2010-04-08 12:26:09 'HTTP/1.1' GET /dataservlet2?timestamp=1270729564199 200 22921 'D2092750B2' localhost 'user75' 2010-04-08 12:26:09 'HTTP/1.1' GET /frontend/includes/functions.css 200 9707 'D2092750B2' localhost 'user75' 2010-04-08 12:26:09 'HTTP/1.1' GET /javascriptservlet?request=common.js 200 5237 'D2092750B2' Other than moving the dynamically generated javascript into the main body of the page, is there a way I can stop this from happening?

You probably get your DataSources from JNDI, not Tomcat (though Tomcat
does populate the JNDI context for you). There's a tool that I can't
seem to find right now that basically provides a simple JNDI context
that you can stuff full of data in your setUp method. In lieu of that,
try reading some of these pages:
http://www.coderanch.com/t/96030/Testing/Unit-testing-testing-JNDI-lookups

Maybe most useful:
http://commons.apache.org/dbcp/guide/jndi-howto.html
2) I get the path in the file system to my Tomcat folder from Tomcat,
which is very convenient, but in consequence every path to a file in my

Do you mean that you use ServletContext.getRealPath or something similar?
For example I'm trying to test a method which uses a value from a

How do you get the file path?

There's also HttpUnit if you want to test using HTTP calls.
But more important is the fact that it doesn't appear to be supported
any more since it uses an old version of Junit without annotations, and
I'm already used to the new version.
IIRC, JUnit is very backward-compatible with itself.
I could probably code round the problem: but the recoding - just so that
I can test things effectively - will be enormous.
We got around the problem by putting our DataSource acquisition into a
separate class, something like this:
public interface ConnectionFactory
{
public Connection getConnection() throws AppException;
}
public class JNDIConnectionFactory
{
public Connection getConnection()
{
InitialContext ctx = new InitialContext();
..
return ds.getConnection();
}
}
public class BaseService
{
public static void setConnectionFactory(ConnectionFactory cf) { ... }
public static ConnectionFactory getConnectionFactory() { ... }
public Connection getConnection()
{
return getConnectionFactory().getConnection();
}
}
public class MyActualService
extends BaseService
{
public ListFoo getFoos()
{
Connection conn = getConnection();
..
return foos;
}
}
This allows us to run tests like this:
public void setUp()
{
Connection conn = DriverManager.getConnection(...);
BaseService.setConnectionFactory(new SimpleConnectionFactory(conn));
}
or, if we want to skip the database altogether (which is usually the case):
public void setUp()
{
Connection conn = new FakeJDBCConnection();
BaseService.setConnectionFactory(new SimpleConnectionFactory(conn));
}
By moving all our JNDI code into the JNDIConnectionFactory class, we
avoid lots of JNDI code in other places, and also gain the flexibility
of being able to swap-in code that gets JDBC Connection objects in other
ways.
Still, I /swear/ that there's a simple standalone JNDI provider out
there somewhere...

Now that the amount of data is increased and the user using the app increased as well, lagging has been happening. You can use VisualVM and JConsole to examine the running JVM. Find out what is actually going on inside your application before you fiddle with settings again. Increasing the amount of memory can sometimes hide a memory leak, for example by not properly returning a database connection to a pool. The settings above I set it in the Tomcat Service monitor. And yes, I also set tomcat as service. So when you said, it didn't make any difference did you mean that the settings weren't applied, or that they were but things haven't improved? It's running 32 Bit windows 2003 only With 8GB Ram. The tomcat version is 6.0.14. The current version is 6.0.24. Upgrading is a good idea. I am not assuming either tomcat is the problem or my software. I am merely trying to find a way out and I have exhausted my resources to make the software as fast as possible. Tomcat setting is the only thing that I have not explore extensively since I am not as expert as you guys. Maybe I can learn a tip or two to make things better. I would say that 99% of the tweakable performance is related to your application and 1% is with Tomcat. You need to establish if there's a bottleneck, and if so, where it is. By the way the number of data that is being processed by the heavy app is in millions of rows. I ran the SQL directly to the mysql server and it worked ok (within minutes and not freezing the server). Meanwhile, when the query is being run via tomcat, then it will freeze the server as well. It does not kill the server, just consume all the server resources, but eventually will come back to normal after two hours with the result. So a single query is using up all the resources on the server? Is the database running on the same server as Tomcat? When you run the query in your application how are you doing it, e.g. by calling a stored procedure, or by executing exactly the same SQL statement?

What makes you think Tomcat and not your application is the source of your problem? If upgrading the server doesn't make a difference, perhaps this points to something that isn't affected by the processing power of the server as the source of the problem. Is there any way to improve tomcat's performance? It is possible to tune Tomcat, but in the vast majority of cases the application is the problem. Tomcat is used in many high-load situations with great success. Will there be any use of Java NIO Framework in tomcat? There is the NIO Connector. It's not guaranteed to make a difference as the usual source of the problem is in the application. I mean apache has Mina, why not combine with tomcat?

trying to test individual components via pure Java calls?
1) I get my datasources from Tomcat, so I can't get to them from Junit
You probably get your DataSources from JNDI, not Tomcat (though Tomcat
does populate the JNDI context for you). There's a tool that I can't
seem to find right now that basically provides a simple JNDI context
that you can stuff full of data in your setUp method. In lieu of that,
try reading some of these pages:
http://www.coderanch.com/t/96030/Testing/Unit-testing-testing-JNDI-lookups
http://ericholsinger.com/programming/java/junit-testing-jndi-datasources-thinking-outside-of-the-container/
Maybe most useful:
http://commons.apache.org/dbcp/guide/jndi-howto.html
2) I get the path in the file system to my Tomcat folder from Tomcat,
which is very convenient, but in consequence every path to a file in my
code depends on this.
Do you mean that you use ServletContext.getRealPath or something similar?
For example I'm trying to test a method which uses a value from a
property file, but I can't do it, because the Junit test can't find the
property file path.
How do you get the file path?
Searching the web again and again has brought up very little except Cactus.
Cactus on paper looks like a good idea, but Cactus has a very low
profile in google searches, which possibly means it is not used much.
There's also HttpUnit if you want to test using HTTP calls.
But more important is the fact that it doesn't appear to be supported
any more since it uses an old version of Junit without annotations, and
I'm already used to the new version.
IIRC, JUnit is very backward-compatible with itself.
I could probably code round the problem: but the recoding - just so that
I can test things effectively - will be enormous.
We got around the problem by putting our DataSource acquisition into a
separate class, something like this:
public interface ConnectionFactory
{
public Connection getConnection() throws AppException;
}
public class JNDIConnectionFactory
{
public Connection getConnection()
{
InitialContext ctx = new InitialContext();
..
return ds.getConnection();
}
}
public class BaseService
{
public static void setConnectionFactory(ConnectionFactory cf) { ... }
public static ConnectionFactory getConnectionFactory() { ... }
public Connection getConnection()
{
return getConnectionFactory().getConnection();
}
}
public class MyActualService
extends BaseService
{
public ListFoo getFoos()
{
Connection conn = getConnection();
..
return foos;
}
}
This allows us to run tests like this:
public void setUp()
{
Connection conn = DriverManager.getConnection(...);
BaseService.setConnectionFactory(new SimpleConnectionFactory(conn));
}
or, if we want to skip the database altogether (which is usually the case):
public void setUp()
{
Connection conn = new FakeJDBCConnection();
BaseService.setConnectionFactory(new SimpleConnectionFactory(conn));
}
By moving all our JNDI code into the JNDIConnectionFactory class, we
avoid lots of JNDI code in other places, and also gain the flexibility
of being able to swap-in code that gets JDBC Connection objects in other
ways.
Still, I /swear/ that there's a simple standalone JNDI provider out
there somewhere...

URLs with '../' and 404s
We use Wicket that periodically redirects to relative URLs starting with '../'. I realize that's against the RFC (which says redirects are supposed to be absolute), but I am not clear on why doesn't Tomcat collapse those URLs in Response.toAbsolute()? Specifically: -assume client is at http://localhost/app/home -app responds to a request with 302 '../home.0' -Response.toAbsolute() rewrites Location as http://localhost/app/home/ . . /home.0 (spaces added to avoid spam filter) But, if client then issues a GET with exactly that URL - and not http://localhost/app/home.0, Tomcat will issue a 404. In other words, toAbsolute() produces a URL that Tomcat cannot service. Why the asymmetry? In other words, why not collapse the '../' in toAbsolute() - and thus produce http://localhost/app/home.0? thanks -nikita
Re: Tomcat does not honor acceptCount configuration variable
Chuck, I would like tomcat to use a maximum of (say) 5 sockets on my system. Further connection requests should be dropped. How may I achieve that ? The acceptCount is the value used by the platform's TCP/IP stack to limit the number of HTTP connection requests held in a queue. The number actually in the queue at any given time is invisible to Tomcat. Which API is consumed by tomcat to relay the parameter to platform ? Timir
Apache Tomcat 5 does not work on port 80
Hi, I have tomcat 5.0 installed on a windows server 2008 machine. Tomcat is the only web server installed. When I change the port to anything other than port 80, for example 8080, I can successfully access the website, but it does not work for Port 80.

Re: Apache Tomcat 5 does not work on port 80
Check you don't already have IIS running on port 80. If you look in Tomcat's logs, there should be a bind exception if that's the case. Is there any reason you're using 5.0? It's very old, and is no longer supported. This means that, for example, it has known security holes and they will never be fixed. - Peter On 8 April 2010 16:33, Sulaiman Paperwalla s...@fiu.edu wrote: Hi, I have tomcat 5.0 installed on a windows server 2008 machine.

Avoiding random JMX port on tomcat
Hi I want to configure JMX on our servers, but I am having problems as JMX opens a second random port. In tomcat 5.5 there was a way to override that port. Is there anyway to do this on tomcat 6? From here: http://tomcat.apache.org/tomcat-6.0-doc/monitoring.html#Enabling%20JMX%20Remote Note:The JSR 160 JMX-Adaptor opens a second data channel on a random port.

RE: Apache Tomcat 5 does not work on port 80
Thanks! IIS is not running on this machine. I checked the logs and they are virtually blank. The logs I checked were jacarta_service_, stderr, and stdout log files. I am using tomcat 5 because the application I am using is not supporting a higher version yet. I am working with the vendor on this but it will take some time but for the time being I'm stuck with 5.0. Let me know if you have any other suggestions I can try.

RE: Tomcat scalability setting - need help please
Clearly instantiating millions of objects is not a strategy for scalability. You're going to have to re-structure your code to reduce the memory footprint of each session. Why is your result set returning a million rows? No human would want to see that much data. You need to restructure your queries and navigation design so that it doesn't do this.

Re: URLs with '../' and 404s
Actually it was pointed out to me that it is the container not the app/framework that is generating the Location header, and so isn't the below a bug in toAbsolute()?

Tomcat 6.0.26 startup scripts changed from 6.0.18
Hi, I am trying to upgrade to 6.0.26 and noticed that the startup scripts have changed slightly. One of the issues that I am having is that the new catalina.sh startup script now checks for the existance of the CATALINA_PID file prior to starting up, and if it exists, it aborts. My problem is that I am creating my pid file in my /var/run directory, which is, by default/design, root access only. However, I launch the catalina.sh startup script under a tomcat user that has very limited read/write access on the system. So what my init.d script currently does is pre-create an empty pid file in the /var/run directory, then changes ownership of it to tomcat so that tomcat can then update it with the actual pid of the tomcat process. Given that there is no way for the startup script to write to the /var/run directory, my options are fairly limited without modifying it. 1) Change the location of the pid file. 2) Make the /var/run directory tomcat writable by default (via acl or by mode permissions) Neither option particularly appeals to me. The fastest solution I have come up with is to modify the condition in the catalina.sh script to check for the existence of a non-empty PID file, instead of just the existence of it (ie: use -s instead of -f). ie: modify the following from: if [ ! -z $CATALINA_PID ]; then if [ -f $CATALINA_PID ]; then echo PID file ($CATALINA_PID) found. Is Tomcat still running? Start aborted. exit 1 fi fi to: if [ ! -z $CATALINA_PID ]; then if [ -s $CATALINA_PID ]; then echo PID file ($CATALINA_PID) found. Is Tomcat still running? Start aborted. exit 1 fi fi Is there a particular reason why this would be a bad implementation? Should I submit a patch request for catalina.sh with this change?

Which native library?
I'm currently using Tomcat 5.5.17 on Windows 2000 32-bit on some servers. (I know, both old, but trying to stretch. Can upgrade tomcat soon but not soon enough.) Java dll is Sun JDK 1.6.0_18 server. I tried loading both 1.1.19 and 1.1.20 versions of the native dll, but apparently Tomcat could not find them. I got unable to locate errors in catalina.log and errors that it couldn't locate the .keystore file (when it should have been using the defined OpenSSL files). I have seen the unable to locate library errors in 5.5.28 installs with 1.1.19 1.1.20, but at least the OpenSSL still worked. I won't be able to upgrade Tomcat to another release for a couple of more weeks (frankly I've been waiting on 5.5.29), but would really like to get the native DLL upgraded to as recent as possible. Does anyone know which is the latest DLL version that will work with 5.5.17? *** NOTICE * This message is intended for the use of the individual or entity to which it is addressed and may contain information that is privileged, confidential, and exempt from disclosure under applicable law.

Re: URLs with '../' and 404s
I strongly advocate server relative URLs which get rid of the whole problem. All that means is the URL becomes everything after the servername port in a full absolute URL. That way it just plain works and even minimizes the browser's understanding of how to compute an absolute URL from a relative one. It's even super easy to create them ... request.getContextPath() + '/app/rel/path/to/myresource.blah' It even takes into account if the app is deployed multiple times in multiple contexts. ie it's always the context in the current request. --David On 4/8/10 4:03 PM, Nikita Tovstoles wrote: Response.java in Tomcat src: http://kickjava.com/src/org/apache/catalina/connector/Response.java.htm On Thu, Apr 8, 2010 at 12:52 PM, Christopher Schultz ch...@christopherschultz.net wrote: Nikita, On 4/8/2010 11:14 AM, Nikita Tovstoles wrote: We use Wicket that periodically redirects to relative URLs starting with '../'.

Your webapp is doing much more with the results than simply listing them Let's examine those possibilities one at a time, shall we? First, if remoteness is incurring a penalty, it's generally because you're transmitting a lot of data. Are you transmitting millions of rows from the server to the client? Why? Is this something that can be done in a stored procedure on the server, or even on a separate, server-only process? IIRC Connector/J, in its default configuration, downloads the entire result set before returning control to your code. That means that if you are selecting millions of rows, you have to wait for them all to go from the server to your webapp, and they all take up a bunch of memory while you're working with them. Have you verified this is not happening to you? Second, have you dumped-out the query your webapp is building to make sure it's the one you think is running? Third, is your webapp doing anything else with these rows other than, say, performing a simple examination of them? I can't imagine why a web application would need to fetch millions of rows at once. I can understand fetching a small portion of millions of rows at once (e.g. SELECT a,b,c FROM huge_table LIMIT 1,100) and displaying them to the user, but never actually transferring that many rows. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAku+VB8ACgkQ9CaO5/Lv0PAxTQCeLdkcbe7sdKz4M3/8ScXCYmRl 4XAAnRbd5z3H4gl7b8Hhxj1n8eAW9G1H =pieL -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: URLs with '../' and 404s
Chuck, Without asserting that Wicket's is NOT breaking an RFC, I would appreciate a clarification on which RFC do you think the framework (or the app) is breaking? HttpServletResponse.sendRedirect allows relative URLs explicitly. From 1.4 EE Javadoc: Sends a temporary redirect response to the client using the specified redirect location URL. This method can accept relative URLs; the servlet container must convert the relative URL to an absolute URL before sending the response to the client. If the location is relative without a leading '/' the container interprets it as relative to the current request URI.

Re: Tomcat 6.0.24 requires me to log on twice

That sounds about right: if you have a page like this: /unrestricted/index.jsp: html img src=%= response.encodeURL(request.getContextPath() + /restricted/sample.gif) % / /html Then your /unrestricted/index.jsp will display and the image will be broken. Note that Tomcat, in response to the request for /restricted/sample.gif will store that request and respond with a login form. When I move on to another page (or reload the same page) I am sent to the logon screen again, after I logon from here everything works as it should. So, if you go to /unrestricted/index.jsp, then hit RELOAD you get a login form? That's weird. The protected resource is some javascript, it is dynamically created as it varies from user to user. What should the behavior be for this resource is the user is not logged-in? Can you simply make that particular resource non-restricted? That would seem to be the easiest solution. This happens on Tomcat 6.0.24 and 6.0.26, but not 6.0.20, which makes me think it is related to change 45255 (Provide protection against session fixation by changing session ID automatically on authentication.), in the dev environment tomcat is running on windows XP. Session tracking is done by cookie, not URL rewriting. I haven't read the actual patch that added this session-id switching but it's not clear if it's configurable. Mark said he'd likely make this an option that defaults to off. Below is a(n abridged) snapshot of the access log, the last field is the cookie sent by the browser dataservlet1, dataservlet2 and javascriptservlet are restricted to logged on users, nothing under /frontend has any security constraints. The sequence of events, from the browser end is (1) A request is made to dataservlet1 (2) The user logs in (and tomcat rewrites the cookie) (3) Is forwarded to the dataservlet1 page, frontend resources are displayed, but the javascriptservlet is not, as it has been requested with the old cookie (this happens on ie and firefox, so doesn't appear to be a browser issue), the apparent attempt to logon for the javascriptservlet also throws another cookie into the mix (4) Another page is requested (5) The user is sent to the login page (6) They log in again (getting a third cookie), and from this point everything is ok #Fields: c-dns x-H(remoteUser) date time x-H(protocol) cs-method cs-uri sc-status bytes x-H(requestedSessionId) #Version: 2.0 #Software: Apache Tomcat/6.0.26 (1) localhost - 2010-04-08 12:25:33 'HTTP/1.1' GET /dataservlet1?timestamp=1205168884309 200 3478 - That looks like it presented a login page (3478 bytes, right?). localhost - 2010-04-08 12:25:33 'HTTP/1.1' GET /frontend/images/image1.gif 200 125 '6A193109AA' (2) Given the timestamp, this was a request for a resource linked from the login page itself. localhost - 2010-04-08 12:25:42 'HTTP/1.1' POST /j_security_check 302 - '6A193109AA' Login attempt. localhost - 2010-04-08 12:25:42 'HTTP/1.1' POST /j_security_check 302 - '6A193109AA' (3) Second login attempt: note the cookie from the client is the same each time.

Re: Tomcat scalability setting - need help please
Hi Chris I stored the result bean in the http request object, NOT IN THE SESSION OBJECT, hoping that once the result is delivered, the beans will die with the request object since request object. I also called the necessary .close() methods and then set the conn, statement, rs, object itself to null. Do you have better way as how to transport this result to jsp? Please enlighten me. Fyi, I must process and send millions of data since my customers usually run analysis processes from 15 different tables with hundred of thousands of data from each table. It is an analysis of 6 or more months of manufacturing data combined with marketing, purchasing, inventory mutations, pricing, production monitoring etc. As what I meant by exhaustive, I went to the extent of building my own cache scheme and it worked, the process still long, but at least it does not kill the other user, but if two or more user doing the same huge process at the same time it will still consume the server.

Consider changing... everything. But I do remember to return the connection to the pool. Super! I also try to kill the statements, result sets, etc by setting them to null. It's better to call [whatever].close(). But I realize that java might wait for the memory to be cleared by the garbage collector. If you're storing all that stuff in beans in the session, you're toast. This goes back to my second problem. If the user closes the browser, the request object form the servlet would lost its way to return the result. And this will hog the tomcat performance for a while.

Fragmented delivery of servlet request
Thoughts welcomed on the following problem : Centos 5.4, http 2.2.3, tomcat5-5.5.23-0jpp.7.el5_3.2, java-1.6.0-openjdk-1.6.0.0-1.7.b09.el5 A large servlet request, POST'ed from client to apache, connected using proxy_ajp to ajp://localhost:8009. reassembled on server eth0 as 10766 bytes but only partially sent to tomcat. Th eth0 line trace to http ( port 80 ) was split over 19 packets of 536 bytes each. My initial thoughts were, that maxHttpHeaderSize=8192, was too low. Increasing to 16384 did not resolve the issue. So more wireshark line traces, ( one tcpdump across eth0 capturing the http POST and a 2nd tcpdump across loopback capturing ajp connector traffic ) revealed, that apache via connector ajp delivered each packet realtime time to tomcat, without waiting for all 10766 bytes to arrive, though the trace across loopback on port 8009, revealed that tomcat starting the reply before all 10766 bytes had arrived. tcpdump on eth0 confirmed, by reassembled tcp segment to contained the 10766 bytes from the browser client. ( Note : I have mangled URI SRV referer host headers ) Apache JServ Protocol v1.3 Magic: 1234 Length: 528 Code: (2) FORWARD REQUEST Method: (4) POST Version: HTTP/1.1 URI: //y RADDR: 192.168.252.68 RHOST: SRV: xxx PORT: 80 SSLP: 0 NHDR: 11 accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-powerpoint, application/vnd.ms-excel, application/msword, */* referer: http:// accept-language: en-us content-type: application/x-www-form-urlencoded UA-CPU: x86 accept-encoding: gzip, deflate user-agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1) host: xxx content-length: 10766 connection: Keep-Alive Cache-Control: no-cache My question is, why did tomcat start to send the RSP ( response ) after only receiving the first data packet from ajp connector, around 500 bytes, when the above states the content length is 10766 bytes. You can also see that subsequent REQ ( request body ) data packets are still transmitted to tomcat, though the response is already being returned. Another option I thought of, was to buffer the whole 10766 bytes up on the apache side, and then get the connector to pass the request across as one 'big' packet. Is this possible to configure ? If so, then maxHttpHeaderSize will come into play, though at the moment only many small packets are being sent across in the fragmented request. A stack dump in catalina.out can be seen below, where the input filter is balking on the POSTed parameters, most likely because only 550 bytes of the 10766, have turned up for the input filter to process.
