Tomcat 5.5 Running out of Threads
Using the manager app (/manager/status) I am seeing multiple threads in the 'Service' mode with times of well over 60 minutes! Here is an example: Stage TimeB Sent B Recv Client VHost Request S 5192947 ms 0 KB0 KB67.152.68.16dev1.mycompany.com GET / HTTP/1.1 I know that these connections came in during a period of particularly heavy load and the server couldn't respond to them right away. No response was ever sent back to the browser but the threads stay open and eat up a resource until the app server has to be restarted. Is there any setting that will cause such orphaned connections to be terminated and returned to the pool? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Tomcat 5.5 Running out of Threads
I have maxThreads set at 250. When a high percentage of that 250 are eaten up servicing essentially dead connections is when the server gets unresponsive. What I am interested in is how tomct can know that a thread is no longer viable -say if it has been in service mode for more than 5 minutes and hasn't sent anything. --- Bovy, Stephen J [EMAIL PROTECTED] wrote: MaxThreads Stephen Bovy Computer Associates 6100 Center Drive Suite 700 Los Angeles, CA 90045 Tel: (310) 957-3930 Fax: (310) 957-3917 e-mail: [EMAIL PROTECTED] -Original Message- From: August Detlefsen [mailto:[EMAIL PROTECTED] Sent: Friday, September 02, 2005 5:21 PM To: tomcat-user@jakarta.apache.org Subject: Tomcat 5.5 Running out of Threads Using the manager app (/manager/status) I am seeing multiple threads in the 'Service' mode with times of well over 60 minutes!

Tomcat not running(4.0.6/5.0.19)-urgent
Dear Sir/Madam, I have been using tomcat 4.x/5.0.x version for web developmen (JSP/Servlets)but i am finding difficulties in starting the server itself many times.I have set the JAVA_HOME environmental variable to the directory where i have installed the j2sdk1.4.2. e.g. E:\j2sdk1.4.2. and under that folder all other subfolders like bin, jre are there.When i am trying to start the tomcat server by double clicking on the startup.bat inside bin folder the tomcat console comes only for 3-4 seconds and then disappears.I also tried to solve it by changing the port no 8080 which is inside server.xml file to any other port (e.g. 9020,8090 etc.),but still it's not working. Also sometimes even though the server starts and runs fine and i am able to see the index.html page(featuring the cat) i get a 404 error of resource not found while trying to access my own webapplication which i create inside the webapps folder.though it is there already.For an example i create a folder named my_apps/WEB-INF/classes inside webapps but i get a 404 error (resource not found) when i type http://localhost:8080/my_apps These two problems are really making me annoyed.I am fade of these problems.Please tell me the solution to these problems.

Re: Tomcat not running(4.0.6/5.0.19)-urgent
It's tough to say what your problem is without more information. Did you check Tomcat's logs to see what the error is when starting up? Have you tried running tomcat from the console instead of from a batch file so that you can see the output of the server when it erors and quits? Give those a try and let us know what the output is and maybe some one can help.

Re: Tomcat not running(4.0.6/5.0.19)-urgent
Thanks for your instant reply.But i just checked whatever u had said.I tried to start it from the console by giving the command %CATALINA_HOME%\bin\startup.bat but same problem still persists.The tomcat console came only for 2-3 seconds and then dissapeared.So i could not read the error messages.I am using Windows 2000 server.some times it runs fine and gives me the desired output. Ok what about that resource not found(404 error).I have created my own folder called my_apps inside webapps and the whole directory structure WEB-INF/classes inside that.but when am typing http://localhost:8080/my_apps in the address bar of the browser am getting this error.Ya one clue is that in the tomcat console am getting org.xml.sax.SAXPARSEException. web-app should match with a ending /web-app.But i have checked my webapplication's web.xml file it is correct and there is no other user's application inside the webapps folder. Currently am doing a project and i need the solution very badly. First let me help in starting the server.What about that logs?

Re: Tomcat not running(4.0.6/5.0.19)-urgent
Try putting an html or jsp file in your my_apps folder. I'm not sure what Tomcat does when you navigate to the web app with nothing other than WEB-INF in the web app's folder. When I navigate to one of my web apps the way you're trying, I get a directory listing of the files and folders I have there, but I notice that that WEB-INF is not included in that listing, even though it is present. So a better test of your web app would be to try to hit an html or jsp page. As someone else pointed out, the log files should give you a good clue as to why Tomcat isn't starting up sometimes. -Mark ayaskant swain wrote: Dear Sir/Madam, I have been using tomcat 4.x/5.0.x version for web developmen (JSP/Servlets)but i am finding difficulties in starting the server itself many times.I have set the JAVA_HOME environmental variable to the directory where i have installed the j2sdk1.4.2. e.g. E:\j2sdk1.4.2. and under that folder all other subfolders like bin, jre are there.When i am trying to start the tomcat server by double clicking on the startup.bat inside bin folder the tomcat console comes only for 3-4 seconds and then disappears.I also tried to solve it by changing the port no 8080 which is inside server.xml file to any other port (e.g. 9020,8090 etc.),but still it's not working.

Re: Tomcat not running
Hello, i have already tested these things which you are telling.When i put some html or jsp files directly ubder my_apps folder i see the list of these files when i type http://localhost:8080/my_apps but my problem is that sometimes i am not able to see this also.it says /my_apps is not available.coming back to your point ya a client can't see the WEB-INF directory.It's kept secret from the client by the server itself.That's why when we run our servlets which we put inside classes folder under WEB-INF we generally call it through a url-pattern which we declare in the web.xml file.

Tomcat 5.0.28 running Windows 2003 Server CPU to 100%
Can anyone point me to a thread discussing the following configuration or something similar, where the discussion relates to the CPU running up to 100%? Windows 2003 Server Standard Edition running IIS 6.0 Tomcat 5.0.28 installed and running (as a service) SQL Server 2000 SP3 connected to Tomcat (and IIS), but running from another server. Our symptom is that after a few days the server CPU usagehits 100%, with Tomcat consuming most of it. Stopping and restarting each Tomcat virtual site, or stopping restarting the Apache service does not resolve the issue. Only a boxreboot will. I need some guidance as to where to suggest to the developers they should look, presuming this is caused by the code. I am the system admin of the environment and so do not develop the code myself, but I am seeing this symptom and now need to ask the developers to examine their code to find a root cause. I bet someone, somewhere, has run across this on a thread on this forum and can point me to it? I've been searching some but have not found much yet that is recent.

RE: Tomcat 5.0.28 running Windows 2003 Server CPU to 100%
Every so often in our development environment, we'll have a page that goes
off in an infinite loop. No problem, we'll just stop the browser, and fix
the page and click refresh. But meanwhile, that first page is still
spinning away, gobbling up CPU.
I once saw code on tomcat-user that allowed me to see what each thread was
doing. It's at the very bottom of this post:
http://marc.theaimsgroup.com/?l=tomcat-user
http://marc.theaimsgroup.com/?l=tomcat-userm=109455426721082w=2
m=109455426721082w=2
I must have found the 'second part' from somewhere else, probably
tomcat-user as well! It's a filter that renames the thread to be the JSP
page that the thread is processing:
public void doFilter(ServletRequest servletRequest, ServletResponse
servletResponse, FilterChain filterChain) throws IOException,
ServletException {
Thread t= Thread.currentThread();
String oldName = t.getName();
HttpServletRequest request = (HttpServletRequest) servletRequest;
try {
t.setName(oldName + - + request.getRequestURI());
filterChain.doFilter(servletRequest, servletResponse);
} finally {
t.setName(oldName);
}
}
combining those two, and you'll get what page is currently processing on
what thread. If you see the same page for more than (the time varies,
but let's say 10 seconds)... then perhaps that page is 'dead' and is
consuming your CPU.

Re: [tomcat] tomcat not running
I know nothing about Turbine and it is Tomcat list. You can better ask it at Turbine list. But on seeing the error message I can give you a checklist. What the application contains.

Re: Setup problem with Tomcat 5.0.25 running as a daemon under jsvc
Sorry for the delay. Was off line for a few days. Fat fingers and in a rush to get out the door. You are correct it is chown. You need to apply it to the tomcat home directory. I do not recommend the chmod 777. Opens things up to much. Okay for testing.

RE: Tomcat not running on Redhat 9 (SOMRAJ)
Hi, You have more than one error: at least two distinct ones. What jars are in your WEB-INF/lib directory? If there's a j2ee.jar there (or anywhere else in your tomcat server installation), remove it. Do you have Axis or Slide installed, thereby causing the log4j warning messages? If so, you need to configure log4j for them.

Re: tomcat 5.0.16 running out of resources
Sun's javac that comes with the 1.3 sdk leaks memory. This is a known issue. 1.4+ and jikes can fix it. To my mind the (much) better way is to precompile your JSPs. Check out: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jasper-howto.html This has the added benefit of avoiding that annoying stuttering when your application is first accessed.

Hi, also consider upgrading to 5.0.18 - there was a memory leak fixed in tomcat. You can search the archive of this conference to find more info.

Howdy,
You can also always add -DthisIsMyTomcat=true (or any other
distinguishing argument) to the java runtime options, so that you can
grep the ps output for this specific parameter if there are multiple
java processes.

Howdy, You have options that check slightly different things: - Ping tomcat's port: checks the server is up, accepting request on the port you check - Specify a CATALINA_PID file, have your standalone program check for presence of this file - Write out your own file from your webapp, have your standalone program check for presence of this file. - Use a tool like Nagios etc. etc. This is a basic operational question.

Re: Tomcat 4.1x running as NT Service Issue
I told you wrong about how to set the memory limits when running as a
service. You can set the memory options in the Windows registry using
regedit.
In regedit, open HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Apache
Tomcat 4.1\Parameters
Add a string value named: JVM Option Number 3 and set it's value to -Xms100m
Add a string value named: JVM Option Number 4 and set it's value to -Xmx100m
Change the JVM Option Count to 5 (was 3 at least on my machine. The value of
this field must match the number of JVM Option Number x values).
You can also write log statements to check allocated and available memory.
Following is an example thread that we used. I've cut out a few parts that
are specific to our application and the formatting is screwed up from
cutting and pasting it, but should be close enough to get you going.
public class MemoryMonitor implements Runnable {
private boolean done = false;
private Runtime rt = Runtime.getRuntime();
public MemoryMonitor() {
Thread theThread = new Thread(this);
theThread.setDaemon(true);
theThread.setPriority(Thread.MIN_PRIORITY);
theThread.start();
}
public void run() {
while (!done) {
try {
long freeMemory = rt.freeMemory()/1024;
long totalMemory = rt.totalMemory()/1024;
long memoryUsed = (totalMemory-freeMemory)/1024;
long allocatedMemory = (totalMemory/1024);
AppLog.info([Memory Monitor] -- +new
Timestamp(System.currentTimeMillis()).toString()+ --- Memory Allocated:
+(int)allocatedMemory+k);
AppLog.info([Memory Monitor] -- +new
Timestamp(System.currentTimeMillis()).toString()+ --- Memory Used:
+(int)memoryUsed+k);
rt.gc();
if(allocatedMemorytotalMemory){
}
Thread.sleep(
MemoryMonitorProperties.getInstance().getCheckMemoryInterval());
} catch (Exception ie) {
AppLog.error(AppError.getStackTraceAsString(ie));
}
}

I'm not sure that this is it, but you might try setting the JVM min and max
memory limits when starting Tomcat by adding the following to
$CATALINA_HOME\bin\catalina.bat:
set JAVA_OPS = -Xms100m -Xmx100m
Default for the JVM I believe should be 64mb, but who knows.
Why are you using jdk 1.3.1? Do you have existing code that is not
compatible with jdk 1.4? We are running Tomcat 4.1.24 as a service under

SP3 and SP4 Pro version. No JSP just servlets. The Tomcat instance is
hosting 2 servlets that talk to a local SQL Server 2000 database on the same
machine. A VB 6 client is talking to the servlets via http post etc, and
exchanging XML documents for requests and replies.
Running as a Service, with JDK 1.3.1 as the JVM the service will crash after
about 10 minutes of activity. Just prior to the crash, available memory will
decrease to 0 and the system will slow to a crawl with a lot of disk
activity, paging I imagine.
Running Tomcat in a window alleviates the problem entirely, so I am assuming
there are some parameters that are being passed via the Startup.bat file
that are not happening with the service. Or perhaps to the JVM, I am very
new to Tomcat so I am not sure how to accomplish this. However we really
want to have Tomcat running as a service since this is a laptop app being
deployed to hundreds of our users, and we don't want them mucking about with
the Window created by running Tomcat as a windowed service.
Plus, having it run as a service means it is one less thing to worry about
in our application
RE: Tomcat 4.1x running as NT Service Issue
I dont think the java versi0on is necessarily a problem however what you need to remeber is when you install the service, you fix the settings of the JVM. If you want to control memory settings, you need to do it in the tomcat.exe command which you run to install the service. My server is down at the moment so I cant give you an example but if you look in tomcat.exe help you can see how to add java options, and one of them will need to be somthing like what was suggested below (ie -Xmx128m). As an aside, I personally wouldnt do the -Xms128m as well because this will mean that that much memory is used up irrespective of requirements. Whilst this configuration is good in a server environment, in a client where memory is more of a premium, you should only default to what you expect it to use on a minimal or average basis. cheers Pete Kiss Technologies http://www.kisstechnologies.co.uk/ 4, Percy Street London W1T 1DF Phone numbers: Phone 020 7692 9922 Fax 020 7692 9923 Robert Porter [EMAIL PROTECTED] 03/08/2003 04:49 Please respond to Tomcat Users List To: 'Tomcat Users List' [EMAIL PROTECTED] cc: Subject:RE: Tomcat 4.1x running as NT Service Issue I am not sure why we are not running 1.4, but the image from corporate has 1.3.1 and we have been told to live with it.

RE: Tomcat 4.1x running as NT Service Issue
I agree with your view on memory usage on a client, but what I am not clear on is do those settings constitute a hard limit for Tomcat/JVM? And if so, what happens when the limit is exceeded, or it attempts to. What we see now is a gradual increase in memory usage over a 10 - 15 minute period, followed by an abend of the Tomcat service. If we run the Tomcat session in a window, using the stock Startup.bat file included with the binary distribution memory usage stays flat. This is what led me to wonder if some of these memory parameters to the JVM (during the install of the service) might be required. I am guessing that the stock install of the service does not set any limit on memory usage? Is this true? Thanks in advance!

RE: Tomcat 4.1x running as NT Service Issue
The settings are not controlled in the startup.bat - if you want to control them from the command line, you set the environment variable JAVA_OPTS with them. The default settings for a Sun JVM is to allow a max heap of 64m - if you try to exceed this, java.lang.OutOfMemoryException s will be thrown and by and large the whole thing will fall over. You can probably see these in the log file if you look. Again if you havent specified anything in the service setup, it will probably run with 64m of memory as well.

While memory usage is much better during the application execution, it still eventually begins a steep climb in terms of memory consumption, even with setting the various memory parameters on the JVM.

Tomcat 4.1x running as NT Service Issue
I have scanned all the archives, and have seen some issues that are similar but not quite the same so I am posting this request. We are running Tomcat 4.1.24 Binary release, as a Service on Windows 2000 SP3 and SP4 Pro version. No JSP just servlets. The Tomcat instance is hosting 2 servlets that talk to a local SQL Server 2000 database on the same machine. A VB 6 client is talking to the servlets via http post etc, and exchanging XML documents for requests and replies. Running as a Service, with JDK 1.3.1 as the JVM the service will crash after about 10 minutes of activity. Just prior to the crash, available memory will decrease to 0 and the system will slow to a crawl with a lot of disk activity, paging I imagine. Running Tomcat in a window alleviates the problem entirely, so I am assuming there are some parameters that are being passed via the Startup.bat file that are not happening with the service.

Re: Tomcat 4.1x running as NT Service Issue
I'm not sure that this is it, but you might try setting the JVM min and max memory limits when starting Tomcat by adding the following to $CATALINA_HOME\bin\catalina.bat: set JAVA_OPS = -Xms100m -Xmx100m Default for the JVM I believe should be 64mb, but who knows. Why are you using jdk 1.3.1? Do you have existing code that is not compatible with jdk 1.4? We are running Tomcat 4.1.24 as a service under Windows 2000 Server accessing an SQL Server database on the same machine with JDK 1.4.1_01 and it is working.

RE: Tomcat 4.1x running as NT Service Issue
I am not sure why we are not running 1.4, but the image from corporate has 1.3.1 and we have been told to live with it. We are running pretty much the same configuration from what you describe but with drastically different results. I am checking on JVM settings, and I will try what you suggest. The laptops are Dell and IBM late models with 256 MB of memory and large fast drives so I don't think it's the hardware. All running W2K Pro with SQL Server 2000 Std Ed. We are using an older JDBC driver, what JDBC driver are you using? -Original Message- From: Nathan Ward [mailto:[EMAIL PROTECTED] Sent: Saturday, August 02, 2003 10:27 PM To: Tomcat Users List Subject: Re: Tomcat 4.1x running as NT Service Issue I'm not sure that this is it, but you might try setting the JVM min and max memory limits when starting Tomcat by adding the following to $CATALINA_HOME\bin\catalina.bat: set JAVA_OPS = -Xms100m -Xmx100m Default for the JVM I believe should be 64mb, but who knows.

jsp:getProperty Bug in TomCat 4.1.18 (running log attached) - stop using tomcat
In TomCat 4.1.18, its impossible to get any bean content as bellow! The
TomCat's running process seems to be WRONG.Why? The code bellow is correct,
and runs fine in OC4J! Unfortunately, I am thinking in stop using TomCat
forever...

But, this bean property is well defined into my Javabeans!!!
Take a look at the log running process of Tomcat:
dica = (euc.Dica) pageContext.getAttribute(dica, PageContext.PAGE_SCOPE);
if (dica == null){
try {
dica = (euc.Dica)
java.beans.Beans.instantiate(this.getClass().getClassLoader(), euc.Dica);
} catch (ClassNotFoundException exc) {
throw new InstantiationException(exc.getMessage());
} catch (Exception exc) {
throw new ServletException(Cannot create bean of class +
euc.Dica, exc);
}
pageContext.setAttribute(dica, dica, PageContext.PAGE_SCOPE);

tomcat service running at 100% cpu ... formerly RE: -Xincgc, -Xms600, -Xmx600
Here's the situation : Tomcat 4.x installed as windows service running continuously at 100% cpu for no apparent reason. Apache forwarding requests to tomcat via jk. I have some thread dumps that look very interesting. It appears that there is a thread issue with jk. Open normal.txt and onehundred.txt in a comparison tool like xdiff and you will see what I am talking about. I attached 3 thread dumps : - normal.txt is the thread dump when tomcat is running as expected - onehundred.txt is the thread dump when tomcat is at 100% cpu. NOTE that no applications are running inside Tomcat. - moreinfo.txt is the thread dump after I logged into the admin page to check the debug options for the jk Connector. Interestingly enough, the Connector page didn't load when I clicked on it(exceptions logged) AND there are even more threads in a wait state. I am looking for suggestions on what to do next. Any thoughts/suggestions are welcome. TIA, Mark PS. Thanks to John Smith for the tip on this, http://www.mycgiserver.com/~tmitevski/adaptj/ , thread dump tool.

RE: tomcat service running at 100% cpu ... formerly RE: -Xincgc, -Xms600, -Xmx600
Howdy, Seems like a JK connector issue. I personally can't help much there ;( - onehundred.txt is the thread dump when tomcat is at 100% cpu. NOTE that no applications are running inside Tomcat. Umm, it does seem like there are all the standard apps (ROOT, admin, manager, examples, tomcat-docs, webdav), as well as two of your own: dependencies, axis. Does the behavior change if you really remove all webapps, i.e. have an empty webapps directory?

Tomcat not running
Hi, I have installed Tomcat 4.1 and under the services running I am able to see tomcat running but when I enter //localhost:8080/ it does not show me the index.jsp page. I had Tomcat running before I installed the Java Web Services Development Kit. Even after uninstall of JWSDK and reinstall of Tomcat the problem persists. I have even checked the registry for any left overs and there are none. I am using XP home. Kindly advise.

RE: Problem with Tomcat Apache running on Different IPs
I don't use JK2, so I cant answer #2 and #3. The answer to #1 is: No, it is not required to run Tomcat and Apache on the same IP address, as long as the relevant properties files for your chosen connector point to the IP address where Tomcat listens. Looking at your URL, it looks like the problems you are having in #1 are virtual host related. If you don't have an Apache VirtualHost for that IP address, and a corresponding connector config, and a corresponding Tomcat Host container, you will get an error. By default, Tomcat is only configured to listen for requests for http://localhost;. If you want anything different, you have to set it up.

Alternatively on *nix (including Cygwin) you can type the following: ps -ef | grep java Of course if you have other java procs running they will show up too. If you wanted to see if it was bind to a port you can check netstat -a for the port # (likely 8080 in default config), but in reality, hitting the port with a browser would be the easiest solution.

Re: how can i make sure tomcat is running?
This is conceptually very easy, but a little tricky because the process identification typically gets cut off for processes that are lengthy. Which is what happens with all the classpath addition, etc. Try this: ps auxw --width=1000 | grep org.apache.catalina.startup.Bootstrap start I tried that briefly and that seems to do it. You could put a line like that in your /etc/rc.d/init.d/tomcatd script and add this line for status. Then you can do this to get the info: service tomcatd status Oscar On Sun, 9 Feb 2003, Mark Liu wrote: I am not sure about linux, but why don't you just try http://localhost:8080 or http://localhost and see? --- Jianping Zhu [EMAIL PROTECTED] wrote: Thanks, can you give me more detailed instruction?

I played around with this a little bit more and this outputs a complete
list of all tomcat processes on a single line. It also avoids listing the
ps command as a found process.
ps ax --width=1000 | grep [o]rg.apache.catalina.startup.Bootstrap start

Re: how can i make sure tomcat is running?
I made a slight mistake. It's printf instead of print for getting it one
line.
ps ax --width=1000 | grep [o]rg.apache.catalina.startup.Bootstrap start | awk
'{printf $1 }'

I played around with this a little bit more and this outputs a complete

This is conceptually very easy, but a little tricky because the process
identification typically gets cut off for processes that are lengthy.
Which is what happens with all the classpath addition, etc.
Try this:
ps auxw --width=1000 | grep org.apache.catalina.startup.Bootstrap start
I tried that briefly and that seems to do it. You could put a line like
that in your /etc/rc.d/init.d/tomcatd script and add this line for status.
Then you can do this to get the info:
service tomcatd status

can't get w2k tomcat service running again
I installed 4.1.16 on a new server (with NT/2K start-as-service option) and did some tweaking (enabled SSL, uncommented servlet invoker, etc...). While I was tweaking I stopped the service because was easier to start/stop via the batch files for quick debugging). When I finished debugging, and tomcat was running normally, I shut down the server and attempted to start it again as a service, but it would not start. The error message was something like cannot start - service does not return an error. Anyone seen this before? I'm running 2000 Server. Any ideas?

How to see JSP error messages while tomcat is running
I recently upgraded from tomcat 3 to tomcat 4.1.12 and am having trouble debugging new jsp pages as I add them. Whereas tomcat 3 would send the error output of a jsp to the html page (making it easy to identify the problem, fix it, and test it again), tomcat 4 sends the output to the context's log file. This would not be so bad, but the log file is locked by my operating system (Windows 98 se) until tomcat is shutdown. The upshot is that for every error, I have to shut down tomcat to see what the error was. Is there any way to see the error output of a jsp page without shutting down tomcat either by a) having the output sent to the html stream; or b) having the log file accessible while tomcat is running; or c) . . . ?

Re: Windows Explorer Hangs when Tomcat is running
I haven't seen this. I start tomcat (4.0.4) manually, but I can run IE and WE just fine. David [EMAIL PROTECTED] wrote: Hi Folks, I am running Tomcat 4.0.1 version on my Windows NT box.

RE: Windows Explorer Hangs when Tomcat is running
Hi Sridhar, Whats your mem usage like? What sp of NT and what JDK? These all can play a role. You might try using a different JDK and see the effects. - Andrew -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 11, 2002 1:52 AM To: [EMAIL PROTECTED] Subject: Windows Explorer Hangs when Tomcat is running Hi Folks, I am running Tomcat 4.0.1 version on my Windows NT box.

Dynamically add jar file to classpath while tomcat is running
Hi all, I'm building a system that must be able to execute any java app that will be uploaded. In fact the server (a web app running under tomcat) just dispatches these applications to other pcs. The problem is that while the server serializes the application class files for dispatching I get a HTTP 500 error on the pcs that want to execute the code. I'm not getting this if I copy the app files (contained in a jar) in the WEB-INF/lib before starting tomcat. So I concluded that the reason for the error is that this jar file is not in the classpath of the web application class loader. First I want to ask if you agree with that. Second, if you do is there a way to add a jar file in the web application class loader classpath, while the application is running. Note that I modified the code so that the jar file is copied in WEB-INF/lib after uploading, but that didn't work.

The problem with the Jar file is that it must physically appear on the CLASSPATH of the ClassLoader for it to be considered, and I don't know of a way to dynamically update the CLASSPATH that would actually affect the ClassLoader. In theory you might be able to simply change the java.class.path System property, but I'd be very surprised if that worked.

One solution, though, is to reserve an actual directory that is on the CLASSPATH and then rather than simply copying the Jar files, actually explode them into that directory. Java's default ClassLoaders seem to pick up new classes within directories that already exist on the CLASSPATH. So, if a Jar was exploded into a directory already on the CLASSPATH (i.e. being monitored by the Java ClassLoaders), then, in theory, those classes would be dynamically loadable into a running JVM. Now, of course, you will have a problem RE loading those applications and classes without a restart, but that's a different topic. Finally, this is all designed to work around the existing ClassLoaders. The real solution is to write your own ClassLoader, and solve it that way. In the 3.2 Tomcat, there's a file org.apache.tomcat.loader.AdaptiveClassLoader (I don't have the 4.x source handy). That can serve as an inspiration.

Without knowing details of the stack trace that you get along with this, it is impossible to understand what is going on. I'm not getting this if I copy the app files (contained in a jar) in the WEB-INF/lib before starting tomcat. Why are you bothering to put this stuff inside the webapp? Wouldn't it be better to run these uploaded applications under a separate JVM, out of a separate directory, where you can configure its own class path totally separate than the one your webapp is running under?

In theory you might be able to simply change the java.class.path System property, but I'd be very surprised if that worked. I would think that the ClassLoader would only read that when it's instantiated and pretty much ignore it afterward. Technically, there is one and only one CLASSPATH environment variable, and one and only one corresponding java.class.path system property, for the entire container. That is obviously not useful in setting up individualized environments for each web application, so Tomcat basically ignores it. Instead, Tomcat builds a hierarchy of class loaders, and offers you places to put JAR files that you want to share across webapps. Online docs are at: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader-howto.html or http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html depending on your version. For example, any JAR file that you put in $CATALINA_HOME/common/lib will be visible to all web applications. One solution, though, is to reserve an actual directory that is on the CLASSPATH and then rather than simply copying the Jar files, actually explode them into that directory. Java's default ClassLoaders seem to pick up new classes within directories that already exist on the CLASSPATH. So, if a Jar was exploded into a directory already on the CLASSPATH (i.e. being monitored by the Java ClassLoaders), then, in theory, those classes would be dynamically loadable into a running JVM. As described above, you cannot use CLASSPATH in a container because it is global to the JVM. Of course, that is one of the reasons I suggested above that perhaps the uploaded apps should be run in their own JVMs. Now, of course, you will have a problem RE loading those applications and classes without a restart, but that's a different topic. That's why it is generally recommended to put JAR files inside your webapp -- then they can be reloaded with just that webapp instead of requiring a complete restart of the container. Finally, this is all designed to work around the existing ClassLoaders. The real solution is to write your own ClassLoader, and solve it that way. In the 3.2 Tomcat, there's a file org.apache.tomcat.loader.AdaptiveClassLoader (I don't have the 4.x source handy). That can serve as an inspiration. There is such a class loader, of course (org.apache.catalina.loader.WebappClassLoader), but let me give you a few words of caution based on my own experience implementing Tomcat 4 -- class loaders are black magic. Anyone who thinks this is going to be a minimal effort approach is going to be very rudely surprised by the complexity. And, even if you go to all of that work, you are most likely going to find something like this happenening to you: * You run your container under a security manager, and trying to create the new classloader throws a security exception * You do something that totally screws up class loading

How to detect whether Tomcat is running?
Hi all, I need to detect the Tomcat status on a production server. I was trying to run a detecting program on the development server. If Tomcat is down on the production sever, I would get an email. I wrote the following codes in my detecting program. I tried to connect the main.jsp page on the production server. But I always got the content length -1. Any good ideals to solve this program? URL url=new URL( http://production_server/prog/ http://production_server/prog/main.jsp); URLConnection con = url.openConnection(); con.connect(); int iLength = con.getContentLength(); Thanks, Jack Li
AW: How to detect whether Tomcat is running?
If you don't change it, the jsp engine always sends content length = -1, as it don't knows how long the output will get at the time it creates the header. So it is better to read the stream and parse the result for the status code. Note taht the content length may be -1 if an error happens because tomcat or the web server might reply with an error page. -Ursprüngliche Nachricht- Von: Jack Li [mailto:[EMAIL PROTECTED]] Gesendet: Montag, 8.

RE: How to detect whether Tomcat is running?
Right...a better method than checking the content length would be to create a JSP page that simply outputs a status string such as Application OK or whatever. Then look for that string in the content that comes back. Just checking for content to come back doesn't tell you that everything is OK, as Ralph pointed out. An error page will have a content lenght greater then -1 or greater than zero.
