RE: Too many jars
Place your JARs in the WEB-INF/lib directory of your web app - or if they are shared in the /common/lib (5.x) location of Tomat. These locations are scanned and used automagically by Tomcat when doing classloading.

After deploying the webapp I am now getting a Jasper compilation error when viewing the JSPs for the first time: org.apache.jasper.JasperException: Unable to compile class for JSP This is apparently due to the fact that classpath parameter is too long for the Windows allowed command line length when the javac command is called. This can be fixed by shortening the names of the jars or moving CATALINA_HOME to be in a less verbose directory location (eg not ..\Program Files\Apache Group\Tomcat.. etc). Does anyone have a better solution for this?

RE: Tomcat 5.5.4 - classes in classpath not being "released"
Hi. Thanks - yes I realise. Wonderin why tihs has been done? Was the old classloader mechanisms in 5.0.x that broken? Not criticising, just trying to understand the reasoning here. Also I tried with the antiARLocking="true", but had some very strange behaviours - I could not delete a jar - in order to replace it. Also, when I used the ant JAR task - it replaced the contents of the JAR, however when I attemted to access my web app Exceptions were thrown regarding unexpected end of ZIP/JAR files etc - specifically when the class that was replaced was looked for by the classloader - after which a class not found exception was thrown! I checked the new JAR using different tools and it is fine!

I think this could be improved, but the penalty will stay significant. antiJARLocking prevents locking through usage of getResource on the classloader (where you get a URL to an entry in a JAR, and which would lock the JAR if you carelessly open it - Xerces with Struts does that) is more limited, but less expensive. -- x Rémy Maucherat Developer & Consultant JBoss Group (Europe) SàRL x - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: help with out of memory error
Greetings. I would suggest using the following switch in your startup - you can research and tweak as required: -Xss512k I have had the same problem you are having on a number of occassions - where the JVM mem usage is NOT high, and the machine apparently has enough RAM allocated. After extensive and mostly fruitless investigation I found that on Windows, each thread created in Java has a native thread created. Now apparently, the default thread stack size on the native side on Windows is 1MB per thread. Thus, I tried setting the thread stack size down (using the -Xss512k switch) to 512 kb per thread (thus in theory doubling my total native thread count maximum?). I must admit that this has helped a great deal! I have not seen that error for about two weeks now and the servers are as busy as they were before. I do not believe that this is a definitive answer to the question/problem - as I believe that this kind of memory problem is related to so many variable problems that there are a number of "tweaks" you need to work out and apply to solve it in your environment. I would suggest you try that switch - also look at other potential helpfuls in the VM option flags as well as potentially compiling with fork set to true... Hope that helps.

RE: Tomcat 5.5.4 - classes in classpath not being "released"
Agreed. Just nice to be aware of the penalties! If you undeploy and redeploy a site (using the core Catalina) classes etc, if this was NOT activated (the antiResourceLocking) would there be any effects? I am not talking about a redeployment via class changes, but a manual redeploy from within code (e.g. get the StandardHost and call remove on the service/engine and then recreate a StandardHost instance with all the relevant settings, then calling deploy and start on it...)

Tomcat 5.5.4 - classes in classpath not being "released"
Greetings. Having the following problem using Tomcat 5.5.4 under JDK 1.5: After running my webapp for a bit in a development environment, I want to copy new and replacement classes to the webapp classes location, but sometimes (about 50/50) I cannot overrite/delete some of the classes - as the VM has not let them go (file handles I assume)? I have to shut the JVM (Tomcat) down before I can deploy my new classes Is this something in the new JDK/JRE (5.0)? Or is this something in the Tomcat 5.5.4 classloaders? I cannot recall (and have not been able to replicate) the problem on 5.0.x under JDK 1.4.x. Any input would be appreciated. Thanks!

keystore manipulation
Greetings. I think I asked a similar question on this list a while ago - but did not get a response - so here goes one last time. I am importing/generating new certificates into the keystore that is set as the truststore for the JVM that runs Tomcat - via the javax.net.ssl.trustStore System property. On first load (when I initial a URL load of a HTTPS URI) all is fine. At this point it seems that the JVM caches the certificates stored in the specified (javax.net.ssl.trustStore) keystore. If, after the first access of the truststore, I import a certificate to the trustore, it is not picked up until a RESTART the JVM. This is problematic as I do NOT want to have to restart the JVM just to read a certificate! Does anyone know how I would refresh the certificate list from the keystore referenced by the SystemProperty: javax.net.ssl.trustStore I would appreciate any pointers! Thanks in advance.

RE: http request sent to https port
Hi. Your HTTP Connector will default to 443 as the redirectPort. You then also must have a HTTPS Conntector listening on 443 in the same engine/service as the HTTP connector (i.e. the host must be accessible on both). The redirectPort will be used if you have a specified in your webapps web.xml. The security contraint can be set to CONFIDENTIAL - do a search on and CONFIIDENTIAL - you should get a number of results back. Briefly a simple security constraint in the web.xml (at the end for my implementations): HTTP Login SLL Forwarding /login/* CONFIDENTIAL Note - you can have multiple of those. Hope that helps.

RE: Buffering and redirection to the errorPage
Greetings. Maybe I should rephrase my question. I do know how and why the behaviour is as it is... Rephrased question: In earlier versions of tomcat - if an exception was thrown and "bubbled" up before the response was committed, it was redirected to the error page. No problem. If the reponse had already flushed, then the tomcat internals would manually request the set error page, passing it the exception, and would append the output of the manual error page call to the reponse, then flush, then return. Is that correct? Is there a reason this is no longer being done? I will emulate it in my system (or at least investigate the viablility therof) if this was taken out for a particular reason.

I thought I posted a reply to this earlier, but I don't see it in my inbox, so maybe I should repost. In a nutshell, this topic makes a lot more sense if you understand what an HTTP request and an HTTP response really look like. My number one recommendation to folks doing web applications is to get a packet sniffer, or a logging proxy, and take a look at what the browser and server are actually sending back and forth. Each HTTP request and response look a lot like an ordinary email: a series of header lines, a blank line, and a message body. The header lines are all name: value. In an HTTP response the body is the HTML of the page, or the binary data of an image. In some cases there is no body at all (a client-side redirect, for example). Any logical operation is handled with a header - setting a cookie, redirecting the browser, etc. Once the blank line separating the header from the body has been sent, you can't go back and send another header line. So you _must_ do any sort of redirect before the server starts to flush output back to the client. If you try to set a header after the server has already sent the blank lnie separating the headers from the body, you'll get a java.lang.IllegalStateException. One way to make this easier to do is to set your buffer larger, so the server will wait longer before flushing output to the browser. Another way is to use an MVC architecture. Have the submit from the browser go to a servlet that does any logical processing you need, but doesn't send any output back to the user. Instead, the controller servlet sets request attributes and user session attributes containing the results of the logic, then redirects the request off to the right view page. The view page looks for the request attributes and user session attributes and generates HTML tags for the display. The controller doesn't muck with display stuff, the view page doesn't muck with the headers. -- Steven J.

Buffering and redirection to the errorPage
Greetings. I have a question with regards buffering of output and subsequent errorPage redirection. Maybe I am missing something. The default buffer size for a JSP page response is 8kb. If an exception is thrown AFTER 8kb has been written (and the initial chunks has been committed) then the redirection to the errorPage (if specified) does not occur. Does this sound right? I have solved this during debugging by increasing the buffer size to a larger kb amount on offending pages, then removing the setting once debugging has occurred. Is there anyway to enforce the redirection to the errorPage? Thanks. Carl - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Compression - problematic?
Greetings. I am trying out the compression feature on the HTTP Connector in Tomcat 5.0.27 and 5.0.28. I have simply set the connector attribute compression="on" - everything else like buffering, socketBuffer etc has been left as default. The default list of MIME types to compress I have also left as per the default. There are some strange things happening - pretty random at this stage. I even had some content from A DIFFERENT HOST (using the same connector) appearing in the output!!! Not sure if this HAS to do with the compression being turned on for the connect - but that is the only major thing that has changed on the server! Anyone have any thoughts/insights?

RE: OutOfMemoryError: unable to create new native thread
Hi Yoav. Thanks for the response. I believe I have found the issue. Apparently Windows NT/2000 defaults to a 1mb virtual thread stack size per thread unless otherwise stated. In addition a maximum of 2gb of thread stack space per process is allowed by Windows (not sure if this can be changed or not!). Thus the tomcat JVM could only have 2000 odd concurrent threads - and on a server that hosts 50 sites, of which 20 are fairly busy this could be a problem. Thus I reduced the thread stack size to 512k (via -Xss512k). In addition there were about 12 connectors in tomcat where the minSpareThreads were set too high - so set them back to default of 4 (from between 50 and 100). Hectic. Now we see how she bahaves!

OutOfMemoryError: unable to create new native thread
Greetings.

Your JVM is bigger than the max process size allowed - Other things I don't know Does anyone have any tips on how to track this sucker down? The OS is Windows 2000 Server Jdk1.4.2_01 Tomcat 5.0.27 How do you increase the max thread count at an OS level?

keystore manipulation
Greetings. Not sure if this is the right place to ask, but I reckon someone here will have some ideas! So here goes... I don't suppose anyone on the list knows of a way to dynamically (from code) reload a previously loaded keystore (e.g. one used with the system property: "javax.net.ssl.trustStore"). Problem I am having is that I programatically import/add a new cert to my keystore no worries. However, on first access of the keystore as specified in the "javax.net.ssl.trustStore" system property, the JVM parses the entire keystore and caches the all the entries. Theen, when I add a new cert, the entire JVM needs to be restarted before it will recognise the new cert entry! Thus, I need to be able to dynamically reload the keystore after adding a new cert to it - or clear the JVM level cache, forcing it to reload. Anyone have any ideas? Thanks.

Server and ServerFactory are in org.apache.catalina, so your code would need to import those classes and run in a classloader that sees them. The other way is using JMX.

RE: Memory settings and thread management

Carl -Original Message- From: Jim Van Fleet [mailto:[EMAIL PROTECTED] Sent: 15 July 2004 05:08 PM To: [EMAIL PROTECTED] Subject: Memory settings and thread management I'm in a little over my head with a task I've got brewing in production land. I'm a junior developer that was hired to be an entire team. Roughly ten times as many people are registered to use the project than I was told, so I purchased more RAM. That makes the machine stats these. Pentium IV 2.4Ghz 2GB DDR ECC RAM Debian Linux 2 stable Tomcat 4.1.30 A segment of the system is designed to send e-mail to everyone on a list. Each e-mail is sent by starting a thread that terminates when the sending is complete. The upper bound of emails in this list is about a thousand, but will rarely exceed five hundred. The system was running as expected (e.g. capable of sending multiple hundreds of messages) before at 512MB of RAM with the following options appended to JAVA_OPTS in catalina.sh -Xms 220M -Xmx 440M Now that the products have gotten the RAM upgrade, I changed these options to -Xms220m -Xmx1536m The result was a drop to about forty messages before I got an "Out of Memory- unable to start new native thread" error. As a result of looking around, particularly at the links like http://h21007.www2.hp.com/cmdspp/QuestionAnswer/1,1764,4AF428BF-32E1-4297-93 8A-0A1F93DE31B1,00.html and http://jboss.org/wiki/Wiki.jsp?page=OutOfMemoryExceptionWhenCannotCreateThre ad I changed the options to these -Xss1024K -Xms1536m -Xmx1536m but this only gets the boundary to about one hundred before thread creation fails. We're nowhere near the process limit for Linux, running at approximately 400 or so. Should I just keep tweaking the configuration settings hoping to find something that works? Give up a little bit more maximum heap size? The one similar post I've seen since March had the user going down to 16k stack size. Is that safe? I can't be blowing my stack on the production machine, that's worse than the problem I have now! I don't have any recursion going on, but I've seen some pretty deep stack traces. Is there something programmatically I could do, like having the call that starts the thread wait for awhile then try again if it fails? I've tried to do my homework, but I think I actually passed my limits on this project some time ago. :-) Thanks and good karma in advance for any and all help.

Actually, you can as far as I know. What is required is a dedicated IP per virtual host. In the tomcat configuration you would add a SSL per virtual host, on port 443 (for example) eah bound to a separate IP - each with its own keystore - containing the cert for the relevant virtual host.

Subject: how to check if a String is empty?
Hello,
maybe this is not the perfect group for my question, but as my problem
appears at the development of JSPs and tomcat is concerned with that, I
hope you can answer it.
I often see the condition
String test = req.getParameter("test");
if (test == null) {
/* string is empty */
} else {
/* string contains something */
}
But if test contains just blanks and other whitespaces, it's not null,
but doesn't contain usable data anyhow. How can I check if a string
contains whitespaces only? I though of something like
if (test == null || test.trim().equals("")) {
}
but there's no trim()-function, right? How do you solve this problem?
With whitespaces I mean blanks, tabs and newlines.
Regards
Marten

Tomcat Stand-alone
Greetings again all. Having a very irritating problem. I am trying to run Tomcat 5.0.25 standalone using 3 HTTP1.1 Coyote connectors - one for "behind the firwall access", one for standard HTTP requests to all hosts and contexts and 1 for 1 site running HTTPS (SSL) on a specific IP. Now, when the server starts all goes well up until near the end - where the following error is thrown in the tomcat logs: 2004/06/18 01:47:32 org.apache.coyote.tomcat5.MapperListener init WARNING: Error registering contexts java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:782) at java.util.HashMap$EntryIterator.next(HashMap.java:824) at java.util.HashMap.putAllForCreate(HashMap.java:424) at java.util.HashMap.clone(HashMap.java:656) at mx4j.server.DefaultMBeanRepository.clone(DefaultMBeanRepository.java:56) at mx4j.server.MBeanServerImpl.findMBeansByPattern(MBeanServerImpl.java:1603) at mx4j.server.MBeanServerImpl.queryObjectNames(MBeanServerImpl.java:1568) at mx4j.server.MBeanServerImpl.queryMBeans(MBeanServerImpl.java:1512) at org.apache.coyote.tomcat5.MapperListener.init(MapperListener.java:115) at org.apache.coyote.tomcat5.CoyoteConnector.start(CoyoteConnector.java:1510) at org.apache.catalina.core.StandardService.start(StandardService.java:485) at org.apache.catalina.core.StandardServer.start(StandardServer.java:2298) at org.apache.catalina.startup.Catalina.start(Catalina.java:556) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39 ) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl .java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:284) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:422) After this, all 3 the HTTP1.1 Coyote connectors are paused. This clearly does not help matters. I read a bugzilla report about a similar problem in Tomcat 4.1.30 - being fixed, and was wondering if this is related and would be fixed for TC 5? (http://issues.apache.org/bugzilla/show_bug.cgi?id=27315) The funny thing is have another server that is identically setup (same hardware, software, same TC, same sites/hosts/context) and this does NOT happen there?

mod_jk2 memory leak?
Greetings. Ok, I posted yesterday about the fork attribute - no response yet and stuff. Now I indicated that the fork setting of true *seemed* to have solved many of my problems RE the apparent memory leak on my server. I am now revising that statement in that the server now stayed up for 25 hours as opposed to the 12 or so it was before I set the fork init-param to true. So now I am where the OTHER memory leak is. I have run profilers on the server and cannot seem to find anything obvious in my code (in fact my code seems to garbage collect very well and properly)... I do recall certain posts on this list about a potential memory leak in mod_jk2 - I am running Apache 2.0.49 with mod_jk2 connecting to Tomcat behind. Does anyone know if this was ever proved to be the case? I will be attempting to run the server on Tomcat standalone - to see if the memory leak persists or not. Anyway, any pointers would be welcome! Regards, Carl Olivier - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Jasper2 fork
Greetings. Quick question re the jasper2 (org.apache.jasper.servlet.JspServlet) fork init param. The default of the fork setting is true, however the Tomcat 5 binary (and I think source) distribution ships with this init-param set to false. Now the reason I am curious about this shipping with this overridden to false is that I have innumerable memory problems - up until I was pointed in setting the fork init param to true. This *seems* to have solved pretty much all my problems! Is there some reason NOT to use this fork setting? Thanks a stack to those that assisted me! Very much appreciated!

RE: HOW-TO : Mail session and authentication password
Hi.
I extended an javax.mail.Authenticator to set username and password for SMTP
authentication:
private static class SMTPAuthenticator extends Authenticator
{
String username, password;
SMTPAuthenticator( String username, String password )
{
this.username = username;
this.password = password;
}
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication( username,
password );
}
}
You then set mail.smtp.auth property to true
When constructing the MimeMessage, use a javax.mail.Session object created
using a Properties instance (with your properties set) and the instance of
the Authenticator (as above) that has the username and password set.
Hope that helps
Carl

Apache and Tomcat - Apache.exe application error
Greetings. I am having a problem with Apache 2.0.49 causing an Application Error on Windows. I know this is the tomcat list - but the issue ony crops up when using mod_jk2 with Tomcat - so I am posting here in case anyone has any ideas?! I have also posted a bug report on the HTTPD bugzilla. I am using Apache 2.0.49 with (major non-standard mods): mod_ssl mod_jk2 with Tomcat 5.0.x being connected to via mod_jk2. I am running on Windows XP Professional, as well as Windows 2000 Server, Windows 2000 Advanced Server, Windows 2003 Server. In all cases I have installed the Apache2 service using the Apache.exe -k install mechanism. When restarting the service using: - net stop Apache2 - The ApacheMonitor interface - The services control panel in windows I invariably get the following dialog popping up: Apache.exe - Application Error The instruction at "0x77f51baa" referenced memory at "0x0010". The memory could not be "written". If you cick OK or Cancel, the popup dialog eternally pops straight back up. Apache DOES actually stop and start OK - but the popup cannot be minimized, closed or anything. It is VERY annoying. Could this have to do with the Tomcat mod_jk - specifcally the sharded memory file (SHM) that both Tomcat and Apache use for workers (if I am understanding that correctly)? This bug was definitely NOT around when I was using Apache 2.0.46 and mod_jk2.02/3, but since upgrading to Apache2.0.49 and mod_jk2.04/5dev it has started. Funny thing is it does NOT happen on all servers! Any assistance would be greatly appreciated!

Server Specs
Greetings. I am hoping someone can give me a helping hand with my query. I a webserver running: Windows 2000 Server Tomcat 5.0.25 Apache 2.0.49 Mod_jk2 J2SDK 1.4.2_01 The server hosts about 80 websites (via name based virtualhosts) with Apache in front of TC for the SSL and static serving. The machine is a quad Xeon (2.4Ghz) Dell PowerEdge with 1GB of RAM. Tomcat currently has 704MB assigned as the max heap size. The problem I am having is that the mahine runs out of memory every day or so, and Tomcat has to be restarted. This is clearly not a good thing! Now, the load on the server is average - nothing spectacular - although some of the sites do get 50 000+ hits per day. The sites use JDBC to a MS SQL 2000 server - the SQL Server is on a differnet machine (similar spec to the web server) on the same 100mb LAN. 40 of the sites are management sites - i.e. thet allow users to manage content (for the other 40 sites hosted) - the management functions include image uploading (using commons-fileupload) document uploading, image manipulation (very limited) etc etc. Each public site (40 in total) are also accessed once every 5 minutes (the index page currently) by a product called Servers Alive to ensure the site is up - if not SMS alerts etc. I am changing that so that SA will access a servlet whch returns plain text (thus less load). I have set the server to use the -XX:+UseParallelGC JVM setting. I have increased the number of maxThreads in both Apache and Tomcat to Apaches (1920) I have run 3 differnet profilers on the server - and cannot for the life of me find a memory leak anywhere. I have NOT tried to use the fork compile setting in Tomcat (read somewhere that this is not good in production?) Is my memory too low? I have just ordered additional RAM (upto 2GB and will assign 1.5GB to Tomcat). Are there other settings I am missing? Is the Garbage collector causing the trouble? I know that this is very subjective situation but I am going completely mad! I appreciate any feedback and suggestions!

RE: Apache/tomcat serving weird pages
I have had similar problems. What version of Tomcat are you using? It could be that your mod_jk2.so is not of the correct version. If you are using TC 5.0.19 you should be using jk2.04 Carl -Original Message- From: Mike DiChiappari [mailto:[EMAIL PROTECTED] Sent: 12 June 2004 01:02 AM To: [EMAIL PROTECTED] Subject: Apache/tomcat serving weird pages I am seeing some weird behavior with Apache and Tomcat. When I quickly refresh the page from the browser, sometimes the wrong page appears. We have two web sites on our server with virtual hosts. If I am reloading a page on web site A, sometimes a page from web site B appears. This seems to only occur with JSPs. I am using Apache 2.0, Tomcat 4.1.24, and I believe jk2. I didn't originally configure the server. But this is how it seems to be configured. The workers2.properties file contains two workers - one for each of the virtual web sites. The lines look like: worker=ajp13:localhost:8019. The line for the other site uses 8009 for the port. The jk2.properties file is very simple. It has the following two lines: handler.list = channerlSocket,request channelSocket.port = 8009 I am still looking into how to interpret these configuration files. Any ideas or pointers would be appreciated.

Sigh, Once again a reply to myself - but the contexts do NOT seem to always come online! Most bizzarre. Does anyone know what that error is? Has it got to do with the cert in the cert store? Please help - this is dodgy.

RE: registering Tomcat as service
Hi. On this subject - in the older Tomcat service executable (specifically jk_nt_service.exe for TC 3) the executable was pointed at a wrapper.properties file. This wrapper.properties provided the means to add new -X and -D properties to the executable without having to re-install the service as it was read in at start time. Is there any plan/chance that this could also be possible for the new tomcat5.exe? The main reason is if you wanted to change the -Xmx setting (as a good example) through code - it is a lot simpler to do this in a wrapper.properties and then simply restart the service - as opposed to removing the service and then re-installing it.

RE: mod_jk problems - Need help!
Greetings.
In the post below - I detail the error I was encountering prior to using
mod_jk2.04 with Tomcat 5.0.19.
After deploying mod_jk2.04 with TC 5.0.19 the problem did not appear again.
Unfortunately the problem is now back (see below for details). It
re-appeared after I upgraded to Tomcat 5.0.24 using mod_jk2.04. I then
rebuilt the mod_jk2.so using the source provided with the TC 5.0.24 source
bundle (which seems to be mod_jk2.05 dev. This did not sort the problem out
at all.
Does anyone have ANY ideas?
Thanks and regards,

Hey.
In reply to my own post:
I have now deployed the latest mod_jk2 buiild (2.04) that I compiled to the

Unfortunately there is one small problem though - which I detailed in a

Subject: mod_jk problems - Need help!
Greetings.
Having a problem with mod_jk2 in some instances. Am hoping someone has some
sort of feedback as to what could be causing it.
Right the scenario:
WinXP Pro
Apache 2.0.49 (with the WinSock2 API disabled - same even with it enabled)
Tomcat 5.0.19 mod_jk2/2.02
The JSP:
A JSP page with a large amount of processing and/or generating a large
amount of HTML to return to the client. The processing is mostly handled
with custom tags on the JSP page. the output uses tables for positioning of
the returning data - and in the offending JSP(s) there is a fair amount of
processing that occurs while builiding the output buffer (note that we are
buffering te output before sending it back to the client.
The problems that occur:
When running through Apache (mod_jk2) to the JSP page all works fine on a
number of JSP pages. At a certain point (always the JSP described above)
the output that is generated from the request is REALLY messed up! Below is
a chunk of the HTML that is returned from the request (sorry it is ugly!):
= BROKEN OUTPUT CHUNK ===
$
= END BROKEN OUTPUT CHUNK ===
In addition, the HTTP headers are also being written out to the content on
the above JSP (as follows) after another batch of similar to above. One
this that is interesting is if you look at the chunk below, you will see
that there are blocks being written to the HTML!! Also these
blocks are for OTHER sites runnin on the same server (same
Apache different Virtual Hosts, same Tomcat, differnet hosts). Note that
all the sites are using the same AJP Connector in the jk comms (the uri
mounts are done in the Apache VirtualHosts blocks using JkUriSet directives
within nested blocks. Anyway, the other messed output chunk:
= HTTP HEADER CHUNK =

The problem NEVER occurs when access the webapp directly via Tomcat (the HTTP1.1 connector) - it only occurs when accessing the webapp via Apache and AJP1.3 using mod_jk2.04. 2. The problem is more apprent if the webapp uses frames in its structure (with each frame containing a JSP that accesses the taglib) 3. If I manually classload the TEI classes in an Init servlet that the container loads at startup the errors do not seem to occur. Is there a difference between some classloader (WebAppClassLoader) initialisation routines if the access is via the Tomcat HTTP connector vs. the AJP JK Connector? Hope someone has some ideas!

Hi all
I'd like to ask you if there's a significant difference in performance
between:
PrintWriter out = response.getWriter();
String ret = "";
for (count = 0; rs.next(); count++)
ret += rs.getString("column_name"); // result of db query
out.print(ret);
out.close();
and:
PrintWriter out = response.getWriter();
for (count = 0; rs.next(); count++)
out.print(rs.getString("column_name"); // result of db query
out.close();
I know I have the extra string which is (theoretically) a slow-down but I
don't know anything about the way how tomcat handles with large strings (in
my
case about 1MB), if is there any limited buffering etc.
I know as well I can test it by myself very easilly but I hope someone's
gonna give me a bit of explanation along with 20 funny stories etc. :)

RE: mod_jk problems - Need help!
Hey.
In reply to my own post:
I have now deployed the latest mod_jk2 buiild (2.04) that I compiled to the
server mentioned below. The problem has now gone!
Unfortunately there is one small problem though - which I detailed in a
Bugzilla post:
http://issues.apache.org/bugzilla/show_bug.cgi?id=28758
Any input would still be appreciated!
Best regards,

Subject: mod_jk problems - Need help!
Greetings.
Having a problem with mod_jk2 in some instances. Am hoping someone has some
sort of feedback as to what could be causing it.
Right the scenario:
WinXP Pro
Apache 2.0.49 (with the WinSock2 API disabled - same even with it enabled)
Tomcat 5.0.19 mod_jk2/2.02
The JSP:
A JSP page with a large amount of processing and/or generating a large
amount of HTML to return to the client. The processing is mostly handled
with custom tags on the JSP page. the output uses tables for positioning of
the returning data - and in the offending JSP(s) there is a fair amount of
processing that occurs while builiding the output buffer (note that we are
buffering te output before sending it back to the client.
The problems that occur:
When running through Apache (mod_jk2) to the JSP page all works fine on a
number of JSP pages. At a certain point (always the JSP described above)
the output that is generated from the request is REALLY messed up! Below is
a chunk of the HTML that is returned from the request (sorry it is ugly!):
= BROKEN OUTPUT CHUNK ===
$
= END BROKEN OUTPUT CHUNK ===
In addition, the HTTP headers are also being written out to the content on
the above JSP (as follows) after another batch of similar to above. One
this that is interesting is if you look at the chunk below, you will see
that there are blocks being written to the HTML!! Also these
blocks are for OTHER sites runnin on the same server (same
Apache different Virtual Hosts, same Tomcat, differnet hosts). Note that
all the sites are using the same AJP Connector in the jk comms (the uri
mounts are done in the Apache VirtualHosts blocks using JkUriSet directives
within nested blocks. Anyway, the other messed output chunk:
= HTTP HEADER CHUNK =

Now the reason I believe that this is a mod_jk2 (or related) problem is
that, when I access the same JSP page(s) directly via Tomcat (http1.1
connector), this does not EVER happen (except once on Tomcat 4.1.30)! We do
need to run through Apache2 however for various reasons such as static
content serving, SSL certificate management (although this particular site
runs over HTTP).
In the Apache2 error.log file I see a number of these outputs:

There does not seem to be any error reports being generated by Tomcat (in
any of the logs) other than these:

It should also be noted that I have encountered the same (or VERY similar
issues) with mod_jk 1.2 using Apache 2.0.46 and Tomcat 3.2.x, 3.3.x and
4.x.x.
This problem could also be related the the CoyoteeConnector implementation
within Tomcat? I must admit to being at a rather large loss, and this
problem is starting to impact negatively on my business - hence the length
and almost desparate email!
I look forward to any assistance possible!

JK AJP Connectors
Greetings all. I would appreciate some advise on an issue I am experiencing. The problem is as follows: Firstly, lets set the stage: Server: Windows 2000 Server 1GB RAM Tomcat 5.0.19 Apache 2.0.46 mod_jk2 My configurations are: 40 VirtualHosts in Apache with the matching 40 Tomcat Hosts with 1 Context per Tomcat host. Each Apache VirtualHost uses the JkUriSet to map JSP and relevant servlets through to an AJP1.3 worker in Tomcat. Now, the problem is that periodically the sites stop responding due to the AJP Threadpool reaching its maximum limit. Now I could put the maxThread attribute up and still use one AJP connector accross all sites - but as additional sites (Hosts) get added to the server I would need to increase this (periodically). Now - the other option I have is to add a new AJP connector/worker for EACH site (host). This however could cause too many concurrent connections to be "allowed" and thus increase the memory requirement for the server (which is not a major problem). I am unsure (hence this post). Essentially I am trying to figure out a good balance for this problem. Can anyone tell me how JK2 works from a connection level. I know that it uses a pool - but how does this actually function. If I have 40 virtual hosts that use the same worker/connector when are the connections established, and how long do they stay open for? I did a netstat on my server and found over 167 established connections to port 8009 (the AJP Connector port). Do they close? Well, this does not seem to happening as they server does "fall over" when the maximum connection limit is reached. My AJP/1.3 connector looks as follows in my server.xml: Do the maxThreads and minSpareThreads and acceptCount work for the AJP/1.3 Connector? In the TC docs they are not included there? Maybe I am just confused. Any assistance here would be greatly appreciated! Best regards, Carl

RE: mod_jk2 - Win32 Alias problems

I tried to see if there were any other posts regarding this issue - could not find any! The first problem is thus: I have multiple virtual hosts configured in Apache2 and Tomcat5. Some of the hosts have multiple aliases. The confiugration option I am using specifies the ServerAlias entries in the Apache2 VirtualHost blocks where applicable. I have the matching entries in the TC5 blocks. Then for each VirtualHost I have the following JK directive set to ensure that JSP requests are passed to TC from Apache: JkUriSet worker ajp13:localhost:8009 This is the last thing before When using the latest mod_jk (which is now a .so even on Windows it seems - instead of a DLL) the ServerName (main server URL) works perfectly. All JSP posts happily get processed by TC as expected. Problem arises when you access the site using one of the ServerAliases - the index.jsp is processed fine by TC5 - however ALL OTHER JSP requests are being "processed" by Apache (i.e. shows the source as text or asks you to download the .jsp file when the JSP is a HREF link!). This definitely did not happen with earlier version of JK2! Another problem is that sometimes - when there is a highly processor intensive JSP page being processed by TC - or a JSP page that has a LOT of HTML commin back - JK seems to "lose it". The HTML is all messed up - or it does not finish loading - or it includes HTML from JSPs beikng hosted on the same server - but completely different Hosts!!

TEI Classloading
Hi. With regards the TEI classloading issue I mentioned in my previous mail (Issues on Tomcat5.0.19) - I *think* that the engine reports this error - but in previous versions of Tomcat the exception was not thrown (bubbled to the top) - blocking the running of ANY JSP page referencing the taglib in question. Maybe in Tomcat 5.0.19 this exception should be caught and logged but not thrown all the way to the top? Yoav: To replicate it is easy of course: Create a custom tag-lib - the tld file and some classes for the tags - however one or more of your tags MUST have a TEI class in the Tag definition in the TLD file - but the class file this TEI class entry reference must NOT exist in the classpath. This *should* cause ANY page that includes/reference the tag library to throw an exception about not being able to find the TEI class - running in Tomcat 5.0.19. With regards my reasoning - I deployed a site of ours to JBoss (embedding Tomcat 4.1.29) today - and noticed that the ENGINE component was reporting the exception about not finding certain TEI classes - however the webapp deployment worked fine. Now - I know this is not the error I reported in ym last mail - but it is related I think. In my mail I mentioned that on the first request to a site running on Tomcat 5.0.19 after a restart I SOMETIMES (I would say 30% of the time) get the same exception - except that the TEI class the exception was being reported on ACTUALLY DOES exist in the webapp's /WEB-INF/classes path. It seems that the classloader has not finished loading (is that possible?) at the time that tomcat tries to compile the JSP (which involves parsing any custom taglibs the page references). Unfortunately I have not got an EASY SMALL replication the the instance where the the class does exists and the exception is thrown - working on it! Any thoughts will be appreciated.

RE: Issues in tomcat 5.0.19
Hi David. Ok, well I am trying our stress testing out with a LOWER maxThread count and a higher acceptCount. Nice to have some confirmation about the theory! Thanks for your feedback. Yes - those 10 second pages need to be optimised - the problem is that those pages are dependant upon data retrieval - with the AMOUNT of data being variable. Also the implementation of our tag library by a web developer could be done in a number of different ways - so we will need to get the subroutines optimised as much as possible!

Maybe set the acceptCount > up.hmmm - thoughts? I think you've found the problem. If you have a page which takes 10s to process (and you say that it's CPU bound, not IO bound), once you have as many threads running as you have CPUs on your server, that 10s is goint to start taking a longer. You said your server was a single CPU machine, so if you're running 2 concurrent threads, now it will take 20s per request to process. There isn't much you can do. You need to limit the number of concurrent requests so that at maximum load, your slow page takes a reasonable time to complete. Once you hit that limit you either need to start queueing requests or rejecting them. If you don't, the server will just bog further and further down. Once you get more than 10 or so CPU hogging threads going at a time, performance will really start to degrade and requests will take longer than 10x to complete than usual due to context switching overhead. You can limit the number of concurrent requests at the connector level and then you might want increase the accept count as you suggested. The next thing you'll want to do is figure out how to turn those 10s page requests into 1s or less. ;-) -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Issues in tomcat 5.0.19
Oh, by the way - one thing: When we tested Tomcat standalone it was actually worse than when we run it through Apache and mod_jk. The reason is clearly that as Tomcat slows down, even the static content (none JSP/servlet) takes ages to come back - whereas through Apache, Apache would serve that quickly without sending to tomcat (thus taking some load off). An interesting thing we noted recently is that it seems to be the processing time more than anything else that causes trouble, not throughput (which is good). Could the problem be that too many high processor-requirement threads are being started, and as such each gets less time on the processor - thus taking longer to process..and thus, should we not set the AJP worker maxThreads DOWN thus allowing the processor to finish each processor intensive task quicker? Maybe set the acceptCount up.hmmm - thoughts? Thanks!

We have run a profiler on the SQL Server - and that definitely does not have a bottleneck - very quick indeed. 2. Memory: this used to be our biggest problem; however, increasing the heap and using the -XX:+UseParallelGC switch seemed to solve most of our memory problems.

The number of concurrent requests and the fact that pages and the >request reponse times are getting slow cause a major bottleneck in Tomcat - >which leads to the piling up of queued requests - until the acceptCount is >reached - and the server becomes totally unresponsive. Are the requests slow because your tags take a while (you mentioned they were "big" tags, which I assume means they do a lot of work)? Or are they slow because tomcat is churning? I
RE: Tomcat Java OutOfMemory Error
Hi. When using the jk_nt_service.exe you need to setup the wrapper.properties file. The very last line is where you set any additional VM parameters - use that. Thus you would change it from: wrapper.cmd_line=$(wrapper.javabin) -classpath $(wrapper.class_path) $(wrapper.startup_class) -config $(wrapper.server_xml) -home $(wrapper.tomcat_home) To: wrapper.cmd_line=$(wrapper.javabin) -Xms128m -Xmx512m -classpath $(wrapper.class_path) $(wrapper.startup_class) -config $(wrapper.server_xml) -home $(wrapper.tomcat_home) Hope that helps!

RE: Tomcat 5.X - Apache2.X - Mod-JK2
Hi. That is apprently when jk is trying to register the request with JMX. You can disable that (and hence stop the error message) by adding the following line at the end if your jk2.properties: request.registerRequests=false With regards problems and stability the most stable I have been able to get it is with: Apache 2.0.46 Tomcat 5.0.19 mod_jk2.03 - mod_jk2.04 J2SDK1.4.2_01 I would recommend that you compile mod_jk2 for your version of Apache (although I am not clear on how much of a difference this makes?)

InProcess Workers
Greetings. I havea Tomcat 3.2.3 running behind Apache 1.3.20. I use mod_jk to pass request from Apache to Tomcat. I have multiple virtual hosts set up, and each host uses its own worker. >From what I understand this means that each host has its own JVM of sorts? Is this correct? If so, is there any way to restart 1 worker without restarting the rest? Thanks in advance, Carl
