I give up. MVC baby!

How can I programmatically load servlets and servlet mappings in 
Tomcat? I'm using Tomcat 5.0.28.


I'm trying to extend StandardContext to automatically map/assign a 
batch of servlets from a specified jar at startup. I'm having trouble. 
As I try to add these servlets programmatically as the StandardContext 
is starting up, I can't get them to register/load. The servlets loaded 
from the web.xml work fine, but the ones I'm trying to add 
programmatically return null ObjectNames when I query 
context.getServlets(). They are also ignored or not found when I get 
the URL.


Here's the code I'm trying... The most relevant code is in 
addServlet() below - which I'm calling after super.start().

super();
}

public synchronized void start() throws LifecycleException {

super.start();

this.loadServlets();

String[] asServlets = this.getServlets();
for (int i = 0; i < asServlets.length; i++) {
System.out.println("known servlet: " + asServlets[i]);
}
}

private void loadServlets() {

String sParameter = this.findParameter("servlets-jar");
String sBasePath = this.getBasePath();
System.out.println("sParameter: " + sParameter);
System.out.println("sBasePath: " + sBasePath);
if ((sParameter != null) && (sBasePath != null)) {
String sJarPath = sBasePath + sParameter;
System.out.println("servlet jar path: " + sJarPath);
ClassLoader classLoader = 
this.getLoader().getClassLoader();
			//HashMap hashMap = ServletUtility.buildServletMap(sJarPath, 
classLoader); // external lib

HashMap hashMap = new HashMap();
			for (Iterator iterator = hashMap.keySet().iterator(); 
iterator.hasNext();) {

String sPattern = (String)iterator.next();
String sClass = (String)hashMap.get(sPattern);
this.addServlet(sPattern, sClass);
}
}
}

private void addServlet(String sPattern, String sClass) {

		System.out.println("Trying to load servlet for url pattern: " + 
sPattern);


Wrapper wrapper = null;
try {
String sName = sClass;
wrapper = this.createWrapper();
wrapper.setName(sName);
wrapper.setServletClass(sClass);
this.addChild(wrapper);
this.addServletMapping(sPattern, sName);
if (wrapper instanceof Lifecycle) {
((Lifecycle)wrapper).start();
}
System.out.println("succeeded");

}

}

1. try to match the  part with the , maybe 
there's some unmatch item there
2. If U just migrate to tomcat 5, U shd also look the DTD item at the top of 
your web.xml file, which dtd is used by web.xml in tomcat 5

I guess that's all ?

I don't think its a good idea to post it here. The files got thousands
of lines.. perhaps there are specific parts that I should be look in
to?

Re: need help for deployment of unpack apps at Linux Tomcat 5.0

[Lintang JP]

Servlet mapping specifies an
unknown servlet name invoker

Maybe you try to map a servlet name that's not declared yet on web.xml ?
How about your web.xml file ?

Hi Jeffry, are you trying to deploy a .war file ? maybe U should use the 
tomcat manager, usually it's located at http://localhost:8080/manager/html, 
U can deploy your .war files from that tools.

This could be some SQL code in your web app. For instance, it could be a 
JSTL SQL tag or something like that. Something that is using logging 
facilities to print it's error messages.

Nix.

Yea, I accidently hit the send button on the last email before I was done

Thanks for the reply, I actually figured it a few hours later.  I was trying
to do 2/ in your list.  I added a PICS.xml and a DOCS.xml under the
${CATALINA_HOME}/conf/Catalina/localhost/ directory which gave me the PICS
and DOCS contexts.  ie:

[EMAIL PROTECTED] localhost]$ pwd

So, are you trying to
1/ have a Tomcat-run webapp serve content that exists outside of the
context path?

2/ setup the static content as its own webapp (context)?


For #1, the (portable, spec-friendly) way is to write a servlet or
filter to intercept requests for a given URI, open the matching file as
an InputStream, and push the data to the client via the Response
OutputStream.

For #2, I don't remember the exact syntax off the top of my head so I
won't waste your time with something that may not work. =) But it's
definitely possible for a webapp to not exist under the "webapps/"
directory.

Just make sure said webapp has a WEB-INF directory and a web.xml.  Even
a web.xml of just

should do.

RE: Need help exporting contexts not under webapps/

[Fritz Schneider]

Guru,

I got it! Forget about aegean.xml! The key us server.xml! I was able to move
my ROOT directory by adding the following to my  container in
server.xml:

 
  WEB-INF/web.xml 
 

Then all of my subdirectories under c:\www showed up on the server,
including aegean. Other contexts continue to be recognized as deployed apps.

Hello,

In your aegean.xml  try

and then stop and start tocmat. 
Go to the manager application and see if you can see the application

Guru,

Earl isn't the only one trying to do this. Here are the details for my
attempts which may or may not be similar to his:

 - Running TC 5.5.8, JVM 1.5.0_02-b09 under Win XP Pro SP2
 - I have a set of static pages (starting with index.htm) stored at
C:\www\aegean
 - C:\www\agean\WEB-INF\web.xml contains 
 - I wish to access them as http://www.peacham.com/aegean
 - aegean is just one of many such directories.
 - It works if I copy it to {TOMCAT_BASE}\webapps\aegean but that creates
maintenance headaches by coupling the TC directory structure to the web site
directory structure.
 - I have tried building a webapps/aegean directory with just WEB-INF and
adding aegean.xml to {TOMCAT-BASE}\conf\Catalina\localhost containing:



  WEB-INF/web.xml


but all I get is 404 errors and no hint of other errors in the logs. I have
tried a couple of variations with equally poor results.

Thanks for any help you can give

Hello,

I'm in the process of bringing an in-house application up under Tomcat.
Previously we were using Jetty as the servlet container, but for various
reason I'm trying to get said application running with Tomcat 5.5.9 and Java
1.5.0.

The problem I'm having is that there are two directories with a large amount
of static files (pictures, videos, documents, and other forms of media) that
are mounted outside of the webapps/ home.  Under Jetty, there is a
configuration directive that I can use to export these directories under a
URL path.  I'm trying to do that in Tomcat, and the documentation has been
somewhat confusing.

What I've gathered is that this type of configuration should be put under
${CATALINA_HOME}/conf/context.xml however I have been able to do this
successfully.  I've tried putting the following in context.xml but it gives
me errors:




So my question is, in short, given a directory structure of static files,

Share your code, and we can help point out bugs.

Better yet: what does the stack trace indicate is the source of the

I recall getRealPath() doesn't work quite well inside packed WAR files,
if that's how you're running.  

If you're streaming images, why not place them outside of the webapp?
That lets the images and the webapp vary independently.

RE: Need help for case insensitive deployment

[Willy Lin]

Hi Wendy:

Thanks for your tip.  That was it.  I had to use 
instead of .  I also had to play with the directory structure
somewhat to get everything to work.  Here is the final context that I had
for my application.



  

Here is a few things that I learned.

1.  I can't have a docBase in .  Tomcat is using the
docBase from  not matter what I do.

2.  The docBase in  is using the appBase in  as
its root directory.  In my case, it is "~tomcat/webapps/".  When the same
docBase is used by the , the root path is switched to
"~tomcat/".  This caused some problem.  I had to create an empty directory
of "~tomcat/BBS" in order for my application to deploy.  The actual files
for the application is still in "~tomcat/webapps/BBS".

3.  No longer able to use file resources from remote server.  In the
past I was able to set docBase to "//host1/dir1".

It is quirky, but it is working now.  May be things are better in
Tomcat 5.0.  Thank you for your help.

Hi,
Eclipse has a unified flat classloader at runtime.  That means one
log4j.jar.  Although Eclipse offers some nice versioning and reloading
features in this classloader, those don't help in your scenario.  Try
the eclipse user mailing lists or forums.

RE: Need help with Log4j and Tomcat5

[Bill Harrelson]

I have multiple applications, say app1 and app2.  I want separate 
logging for each application.  log4j creates a static repository 
associated with each classloader.  They suggest having separate 
jars in each appx/WEB-INF/lib directory so that log4j's static classes 
create separate repositories because each application uses a 
separate classloader.

This works great.  However, Eclipse doesn't seem to create 
separate classloaders, or something, as only one of my loggers 
works, and then only if I explicitly put /lib/log4j.jar in the classpath.  
There was a thread about this on a WebSphere list that said that 
one had to change WS's classloader default to "Parent-last" but I 
don't know whether this applies to Eclipse.

I'm hoping someone on this list has some experience with multiple 
applications in Tomcat, log4j and Eclipse.  I've been wrestling with 
this for a while and can't find anyone that has been able to help.

TIA

Bill

[Tonte Pouncil]

So you have different log4j jar files?  If so why, why not just use one?

This works fine for me under Tomcat, and works well for multiple 
applications (jars in each WEB-INF/lib, props files in each /class).  
However, when I try to do the same under Eclipse, I get 
classNotFound for log4j.jar unless I put the jars (in each WEB-
INF/lib) explicitly into the Eclipse run/debug classpath, in which case 
it only picks up the first jar and I only get one logger.

Has anybody else run into this?  Anybody have any idea what to do

RE: Need help with Log4j and Tomcat5

[Bill Harrelson]

This works fine for me under Tomcat, and works well for multiple 
applications (jars in each WEB-INF/lib, props files in each /class).  
However, when I try to do the same under Eclipse, I get 
classNotFound for log4j.jar unless I put the jars (in each WEB-
INF/lib) explicitly into the Eclipse run/debug classpath, in which case 
it only picks up the first jar and I only get one logger.

Has anybody else run into this?  Anybody have any idea what to do

RE: Need help - Data Source problem

Hi guys,

I'm pretty much a newbie when it comes to configuring Tomcat, and also with
building JSPs, although thanks to the useful examples and documentation,
I've been able to pick it up pretty quickly.

Anyways, I am interested in using the utilties provided in the
commons-fileupload-1.0.jar file. I downloaded it to the
$CATALINA_HOME/common/lib folder. When I tried to import
org.apache.commons.fileupload.*, I get an error stating that the package
doesn't exist. For the hell of it, I made a standalone java program with the
same import statement, and it worked fine.  Does anyone have any thoughts as
to what else I can do to troubleshoot this problem further?  I am running
Tomcat-4.1.27.

Thanks,
Arun

Supply more information.
What does your server.xml and web.xml look like? (don't post the whole
file, just relevant parts).
Where is your driver jar located? (it should be common/lib)
 
That class of error ("class '' for URL 'null') is fairly common, and
normally it's mis-configuration.

If sure looks that way, but without further information one can't be sure.
It would really help matters if you could post the relevant parts of 
your server.xml. Perhaps there's just a typo or something.

I think you can get the user name by getting the Principal object from

RE: need help adding classpath to Tomcat 5.0.18 NT Service

[Robert Ensinger]

I gave moving the jar a shot yesterday just to be sure but no dice. 

I'm not the developer of this app so I can't speak to why its necessary, but
the only way to get full functionality from this app is to explicitly add
the classpath to the server startup. 
This works successfully on Weblogic 8.1, SunOne, & JRun4. 

I can get the full app to work properly in Tomcat when started via the
startup.bat (classpath added to the setclasspath.bat); now the problem I
need to solve is how I duplicate this success when running Tomcat as an NT
Service.

I haven't found any documentation that specifically addresses adding the
classpath to the nt service startup, so I've tried the approaches listed
below.

Until I can confirm or deny I'm adding the classpath properly I don't know
if I have a bug here. 

I will check if anyone has added an enhancement request for better
documentation on the configure tomcat utility.

If you moved engine.jar from the shared/lib folder to the common/lib folder,
would that remove the need to explicitly set the classpath?

Hi folks.

I'm still unsuccessful at adding an explicit classpath to Tomcat when
running as a service via the -Djava.class.path= switch detailed below.

Can someone confirm or deny that this is the proper way to add an explicit

Subject: need help adding classpath to Tomcat 5.0.18 NT Service

Hi Folks,

I'm working with an app that needs a classpath "kickstart" to
run properly. The jar is deployed to %CATALINA_HOME%\shared\lib\.

 

When starting the server via the startup.bat, the app works properly when
the set classpath variable in the setclasspath.bat is defined as:

set
CLASSPATH=%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\shared\lib\engine.jar

 

Now I wish to see this app run when Tomcat is started as a service.

 

Under Java VM in the configuration utility I have added:

-Djava.class.path="%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\shared\lib\engi
ne.jar"

 

My Java Options box reads as follows:

-Dcatalina.home="C:\Program Files\Apache Software Foundation\Tomcat 5.0"

-Djava.endorsed.dirs="C:\Program Files\Apache Software Foundation\Tomcat
5.0\common\endorsed"

-Djava.class.path="%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\shared\lib\engi
ne.jar"

-Xrs 

 

This isn't working.

I've read the docs and How Tos, spelunked this list, googled, added this
classpath to the systems environmental variables, to the catalina.xml, and
even the catalina.proprties. None of this seems to work.

 

Where is the proper spot to add a classpath to Tomcat running as a service?
What is the proper syntax? (examples?)

 

My java version is 1.4.2. I have successfully setup this app in JRun4 &
Weblogic 8.1 running as services. Need a little help with the Tomcat.

 

Thanks!

RE: need help adding classpath to Tomcat 5.0.18 NT Service

[Filip Hanik \(lists\)]

why don't you just add the files to /common/endorsed/ that way they will get
automatically added to the tomcat classpath without you setting any
variables.

also, setting up tomcat in a file system with spaces in the paths, can be a
debug pain in the butt,
I would try to avoid doing that

If you're playing with a multiple virtual hosts configuration, you really
want to thoroughly understand this page:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/host.html as well as
the Automatic Application Deployment page linked from the above page.

Basically, you add autoDeploy="false" to your Host definition.  You then
have a  element for each of your web applications under each host
where you want them accessible.

If you're playing with a multiple virtual hosts configuration, you really want to 
thoroughly understand this page: 
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/host.html as well as the 
Automatic Application Deployment page linked from the above page.

Basically, you add autoDeploy="false" to your Host definition.  You then have a 
 element for each of your web applications under each host where you want 
them accessible.

Yoav,

Moving to Tomcat 5 is not an option right now.

Your alternative suggestion sounds interesting.
How does the autodeploy feature work?
If I turn it off, how do I specifically name directories (apps)?

Howdy,
So you want to disallow access based on local, rather than remote (the
request's), IP address?  

Remote address filtering is easy: see the Valve How-To page section on
RemoteAddressValve.

Local address filtering is also not very difficult, but requires you to
write some code.  Namely, you will need to write a filter that looks at the
request's local address (HttpServletRequest#getLocalAddr, a new method in
the Servlet Specification v2.4, so you need tomcat 5 for this) and rejects
requests based on your rules.

Alternatively, you can simply not define webapps inside those virtual hosts
where you don't want them available.  Turn autoDeploy off for the host,
explicitly define webapps where you want them.

It's a classic thread safety issue.  Dump your homebrew connection

Shouldn't the port for jk2 connector be 8009 instead of 8010?

Hi,


I'm beginning to think that I need to be a system
administrator to connect Apache 2.0 with Tomcat 5.0!
I've already spent 2 full days trying to get it to
work. I remember that for Tomcat 3.4 it took me about
5 minutes.

(I can't even tell whether there is too much
documentation or not enough. Under
/tomcat-4.1-doc/jk2/jk2/configtcex.html there are many
links and I don't know whether I need some of them or
all of them. I don't know whether 4.1 instruction
apply to 5.0. It is not clear how to modify Unix
instruction for Windows intructions. Ordinarily I'm a
Unix guy (I helped write the Gimp), but this is a
Windows project. How am I supposed to interpret the
sentence "There is no need to use the jkjni logic to
use normal socket, so that just for Fun." What's just
for Fun? jkjni or normal socket? Also, on the menu,
the headers are instiguishable from live links so the
whole structure of the document is unclear.)

Anyway, I think you guys produce amazing products,
I've always used them and will stick by them in the
future. I'm just a little frustrated and a little bit
jealous of my time so I'm hoping that someone will
provide instructions for Apache2 + Tomcat5 + Win32.

Thanks.

other problems I was having also went away. I agree that finding the solution to this 
one was like finding the proverbial needle in the haystack. 

-- Thanks!

Re: Need Help getting SSL to work with HttpsURLConnections

[Mike Kellstrand]

John,

I found a solution.
Add the line below to force it to use the correct libraries:
System.setProperty("java.protocol.handler.pkgs","javax.net.ssl");

This one falls into the inexplicable category of problems that lots
of people must have dealt with, yet Google shows up almost nothing,
and you never get a reply about it in the mail-group.

cranky this morning,
Mike

RE: Need Help getting SSL to work with HttpsURLConnections

[Trenton D. Adams]

I don't think this subject is really on topic for the tomcat list...


import javax.net.ssl.*;
import java.net.*;


public class HTTPTest
{
  public static void main (String args[])
  {
try
{
  URLConnection myConnection = 
(new URL("https://somesite.somedomain.com/";)).openConnection ();
  System.out.println (myConnection.getInputStream().available());
}
catch (Exception exception)
{
  System.out.println (exception.getMessage());
}
  }
} 

Try the following guys, and tell us what happens.

Maybe you might want to email me direct since this is a tomcat list, not a
java list.

Re: Need Help getting SSL to work with HttpsURLConnections

[Mike Kellstrand]

I just came across a similar problem today.

I have working code in a Swing app that uses  import javax.net.ssl.*;

I copied the ssl connection code over to another app
that happens to be a servlet, and I get the ClassCastException as seen
below,
at the line of code:
connection = (HttpsURLConnection) url.openConnection();

Anybody know what is going on?

Thanks,  Mike

Re: Need Help getting SSL to work with HttpsURLConnections

[John Kammer]

An update and a correction...

I was able to get the HttpsURLConnection to work by replacing:

   import javax.net.ssl.*;

with:
   
   import com.sun.net.ssl.*;

Contrary to what I had said below there is an java.lang.ClassCastException being 
thrown when making the call :
   HttpsURLConnection conn = (HttpsURLConnection) myurl.openConnection();

Now the compiler warns me that I'm using deprecated code, but it does work. 
Still, why would javax.net.ssl.* be having this problem ? 

Thanks again!

Re: need help

[Jean-Francois Arcand]

No that's not true. you *don't* need 1.4. Should work with 1.3.x

Open your catalina.bat file and add a line at the end of the script:

pause

Then start your script and post the exception you are seeing here.

Hello Gokul,
  It's helpful if we can see the exception, so you might want to
run the script file catalina.bat located in
 the bin directory.
Run it with:catalina run
This makes tomcat run in the current window and you will be able to see
the exceptions. I'm not really sure if jdk1.3 works
with Tomcat 5 (some one correct me quick) , so keep that in mind as
well. Cut the exceptions and send it back to the list
to have a look.

If you are running under Windows98, and you are trying to use a PIF - (like a 
shortcut), you must make sure the memory allocation is set to 4096 bytes. If 
you keep it set to "auto" the startup fails. Or at least it did years ago 
when I last tried using it under 98.

The problem is that the classpath and system variables set up by the startup 
scripts run out of space.

Hope this helps.

Re: need help

[Kwok Peng Tuck]

Hello Gokul,
  It's helpful if we can see the exception, so you might want to 
run the script file catalina.bat located in
 the bin directory.

Run it with:catalina run
This makes tomcat run in the current window and you will be able to see 
the exceptions. I'm not really sure if jdk1.3 works
with Tomcat 5 (some one correct me quick) , so keep that in mind as 
well. Cut the exceptions and send it back to the list
to have a look.

Re: Need help : how to shutdown & restart Tomcat, how to reload servlet

[Aurele Venet]

Hello Vincent,

fro problem 1:
you are using the correct procedure, but it looks like your server was 
never started in the first place.  The connection refused is due to the 
fact that it tries to connect to a port (for shutdown procedure) which 
is not open.  Alternatively, tomcat can some time get stuck and I notice 
that I cannot shut it but it is still running.  In this case you need to 
kill the java process associated with the tomcat server.

Normal procdure of start and stop should work fine.  Look at the end of 
the catalina.out file to see normal starting and shutting down procedure 
logging.

for problem 2:

I have recently installed tomcat 4.1.24 which has a good manager 
interface that allows to start/stop/remove/deploy applications without 
shutting down the server.  A remove/(re)deploy process running from an 
ants script takes me 4 secs to execute (I am on solaris sunblade ws).

Re: Need Help For Iplanet Tomcat Configuration

[Eric J. Pinnell]

Hi,

I'm not sure if cross posting like that was such a good idea...  But since
I just had to figure this out last week I will share what I learned.

I had to play with this a bit befor I was able to get it to work. I was
using Solaris so I can't help you with the correct version of the
redirector DLL.  I hope this will help.

The documentation isn't entirely correct here.  Put "servlet" in quotes.
Otherwise iPlanet doesn't see the object name and the assigment you made
in the default object section won't work (you will get that error once you
fix the stuff below). It also wouldn't hurt to put "text/plain" in quotes.

That's exactly what it is doing.  So you have to fool it.  In your iPlanet
docroot create the directory examples.  iPlanet will see it and think it's
there.  Then when it tries to serve it the changes in obj.conf will kick
in and send the request to tomcat.

In some cases you will find that you have to "touch" (create 0 length
files) in some cases to fool netsacpe into thinking it's there.  Usually
it's just index.jsp.

I also connect to the Coyote/JK2 AJP1.3 connector on the tomcat side and
not the older AJP 1.3 connector.

Constant memory usage as viewed by top or other host operating system
commands is normal. The sun 1.4.1 JVM doesn't seem to shrink it's memory
usage. If you've ever used that much memory, it won't be freed just
because you no longer use it all. 

I believe the memory limits are limits that apply to java objects, not
to the overhead of the VM, so the actual memory allocated from the
operating system is always more than what is available to your program
and can be more than the memory limit. I'm only guessing here though.

I would use a network packet sniffer and see if you can isloate what is
going on at the network level. Ethereal is my favourite.

ditto.

There is no sure fire way from the system aspect (CPU, run queue, etc)
that will tell you what's going on.  You need to peek inside the VM and
see what it's doing.

Re: Need help with performance issue - Tomcat 4.1.X

[Simon Pabst]

-verbose:gc may affect performance a bit (cpu/disk), but since your system 
doesn't run so well anyway, oh well :-)

Using a higher acceptCount doesn't hurt much (needs maybe 1k memory for 
each queue place i think)

On earlier Java Versions there is a switch to turn on incremental Garbage 
Collection (off by default), -Xincgc (may decrease performance)
which is kind of similar to Concurrent GC i think, so worth a try if 
nothing else helps

I created a hello.jsp, which is completely separate from our 
application.  Same
results.  It takes about 30 seconds to return.

In the hello.jsp, the results of the page return instantly to the browser, 
but
then it's as if tomcat just won't close the connection to the browser.  The
page is there, fully rendered, but just sits there waiting for the server to
tell it it is done.  Is there some way that the tomcat connections could be
failing to terminate properly?

Our current maxProcessors = 75
acceptCount = 10 (which is probably low but right now we have only a couple
users on the system).
We're not using 1.4 so those options are out.

RE: Need help with performance issue - Tomcat 4.1.X

[Lars Hellgren]

If your JVM runs out of heap space, you should get an
OutOfMemoryException thrown.  Same, if you don't have sufficient stack
space, you should get a StackOverFlowException.

I had a problem with a JSP that sometimes would take as much as 15
minutes to serve. It creates a table of sometimes a few hundred rows,
each containing a selection box and a submit button. I ended up
rewriting it as a Java class that first builds the outtput message in a
StringBuffer using append() and then writes the buffer to the output
stream in a single operation. That increased performance by more than
one order of magnitude. I suspect that there is an issue with the way
Jasper created servlets use the out.write()/out.print() methods.

Re: Need help with performance issue - Tomcat 4.1.X

[Simon Pabst]

Tomcat 4.1 processes need some extra memory besides the heap i believe,
so the total process memory will always be bigger than the maximum 
specified heap
(unless this isn't a bug or a misunderstanding of me of course :-)

Our Tomcat 4.1.24 on Redhat Linux with 1GB heapsize consumes about 1,25GB 
Memory at its maximum.

I created a hello.jsp, which is completely separate from our application. 
Same results.  It takes about 30 seconds to return.

In the hello.jsp, the results of the page return instantly to the 
browser, but then it's as if tomcat just won't close the connection to 
the browser.  The page is there, fully rendered, but just sits there 
waiting for the server to tell it it is done.  Is there some way that the 
tomcat connections could be failing to terminate properly?

Our current maxProcessors = 75
acceptCount = 10 (which is probably low but right now we have only a 
couple users on the system).

We're not using 1.4 so those options are out.

Could be a Memory Leak/Garbage Collection issue (we had a similar 
problem with a memory intensive app),
maybe your heap is too small and java is running many Full GC's.
Start java with -verbose:gc and look in tomcat/logs/catalina.out for 
Garbage Collections.
(set Environment Variables JAVA_OPTS or CATALINA_OPTS in bin/catalina.sh 
to do this in Tomcat)



Try using a bigger Heapsize (though if you've got a Memory Leak that 
will only delay your problem)
or set initial Heapsize to same as maximum, for example 128MB:
-Xmx128m -Xms128m



Modify the Connector you are using to access Tomcat (in 
tomcat/conf/server.xml) and
try using more Tomcat Processors (maxProcessors=XX) or a bigger accept 
queue length (acceptCount=XX)
(test value for acceptCount: at least > concurrent users x 3)



Try using another method of garbage collection,
if you're using JDK 1.4.1 i'd try either

ConcurrentGC with ParNewGC (ParNewGC on Multi-CPU machines):
-XX:+UseConcMarkSweepGC -XX:+UseParNewGC
or ParallelGC with AdaptiveSizePolicy (saves you the work of Java Heap 
usage analyzing :-) :
-XX:UseParallelGC -XX:+UseAdaptiveSizePolicy

A good article on GC can be found here:

Re: Need help with performance issue - Tomcat 4.1.X

[tomcat-question]

Yes, still running on the same tomcat, which is standalone BTW.

The problem occurs with both IE and mozilla, but a little differently.  Mozilla 
tends to render the results immediately, then sit there for 20 seconds.  IE 
will wait a bit, render the results, then sit there.

I'm assuming the difference is simply an artifact of when the browser chooses 
to render its cache on an open connection.

Neither browser is closing the connection to fast...  Opposite problem :-)

And no, I haven't tried any of your other recommended steps yet.  We're trying 
to do as much as we can without bringing down the system, since it's a 
production system (and we have yet to reproduce on a test system).

Re: Need help with performance issue - Tomcat 4.1.X

If your application is running on same Tomcat/JVM then blocking GC calls 
could still lead to that effect for hello.jsp too.

Are you using Apache/mod_jk/Tomcat or Tomcat standalone?
HTTPS Connections?
Does the Problem occur only with IE or with other Browsers (Mozilla) too?
I read once something about a problem of IE closing http connections too 
fast when it thinks the page transfer is finished.

But again, the mx is only setting the heap size, not the whole JVM.  The thread

I found this with a quick search:

"The -Xmx setting controls the maximum size of the Java heap.

I have no idea, but based on past experience, if you are using more RAM 
than you've allocated, then you have a swap situation.  If the max setting 
wasn't an actual max, and you could blow past it whenever you needed it, 
why on earth would you need it in the first place?

we're not using) be taking up the remaining 75MB?  We have about 40 
threads started right now.

Like I said, I don't know enough about java's memory allocation, but I 
didn't think that the -Xmx set the maximum allowable total memory for the 
JVM.  Am I mistaken?

Even if memory were a problem, which it may be, would that account for a 
20 second delay between serving a page and closing the connection?  
Remember that we currently have no load and only a couple users on the 
system.

I'm certainly no guru, but if you are setting a max of 256 and then your 
app is soaking up 327 with no load whatsoever, I'd say you have a 
problem.  Have you tried a max of 512?

Re: Need help with performance issue - Tomcat 4.1.X

[tomcat-question]

I definitely don't know enough about how the memory settings in java to be of 
much use on this part.  I do not know if we've tried 512.  We probably should. 

As for the 327, is that actually unreasonable?  The mx setting specfies the 
maximum heap size.  Can the thread stack (specified using -Xss, which we're not 
using) be taking up the remaining 75MB?  We have about 40 threads started right 
now.

Even if memory were a problem, which it may be, would that account for a 20

Could be a Memory Leak/Garbage Collection issue (we had a similar 
problem with a memory intensive app),
maybe your heap is too small and java is running many Full GC's.
Start java with -verbose:gc and look in tomcat/logs/catalina.out for 
Garbage Collections.
(set Environment Variables JAVA_OPTS or CATALINA_OPTS in bin/catalina.sh 
to do this in Tomcat)



Try using a bigger Heapsize (though if you've got a Memory Leak that 
will only delay your problem)
or set initial Heapsize to same as maximum, for example 128MB:
-Xmx128m -Xms128m



Modify the Connector you are using to access Tomcat (in 
tomcat/conf/server.xml) and
try using more Tomcat Processors (maxProcessors=XX) or a bigger accept 
queue length (acceptCount=XX)
(test value for acceptCount: at least > concurrent users x 3)



Try using another method of garbage collection,
if you're using JDK 1.4.1 i'd try either

ConcurrentGC with ParNewGC (ParNewGC on Multi-CPU machines):
-XX:+UseConcMarkSweepGC -XX:+UseParNewGC
or ParallelGC with AdaptiveSizePolicy (saves you the work of Java Heap

-XX:UseParallelGC -XX:+UseAdaptiveSizePolicy

Re: Need help with performance issue - Tomcat 4.1.X

[tomcat-question]

Another followup.  If we try to access the root context of the server, which is 
not available, the same thing happens.  I get back a 500 error immediately, but 
then the page doesn't finish "loading" (i.e. get all the response back from the 
server) for another 20 seconds or so.

This seems like a connection problem rather than a memory problem.  Thoughts?

Re: Need help with performance issue - Tomcat 4.1.X

[tomcat-question]

We are currently starting up with -Xmx256M.  Java is currently using about 
327MB and has been that way for hours.  I haven't really seen any fluxuations 
at all, which leans me away from the garbage collection issue.

I created a hello.jsp, which is completely separate from our application.  Same 
results.  It takes about 30 seconds to return.

In the hello.jsp, the results of the page return instantly to the browser, but 
then it's as if tomcat just won't close the connection to the browser.  The 
page is there, fully rendered, but just sits there waiting for the server to 
tell it it is done.  Is there some way that the tomcat connections could be 
failing to terminate properly?


Our current maxProcessors = 75
acceptCount = 10 (which is probably low but right now we have only a couple 
users on the system).

We're not using 1.4 so those options are out.

I don't believe that the host lookup or db connection is the issue.  The page 
we are serving up is the login page.  I will create a test "hello world" jsp to 
see if the problem still occurs with that page.

Could be a Memory Leak/Garbage Collection issue (we had a similar problem 
with a memory intensive app),
maybe your heap is too small and java is running many Full GC's.
Start java with -verbose:gc and look in tomcat/logs/catalina.out for 
Garbage Collections.
(set Environment Variables JAVA_OPTS or CATALINA_OPTS in bin/catalina.sh to 
do this in Tomcat)



Try using a bigger Heapsize (though if you've got a Memory Leak that will 
only delay your problem)
or set initial Heapsize to same as maximum, for example 128MB:
-Xmx128m -Xms128m



Modify the Connector you are using to access Tomcat (in 
tomcat/conf/server.xml) and
try using more Tomcat Processors (maxProcessors=XX) or a bigger accept 
queue length (acceptCount=XX)
(test value for acceptCount: at least > concurrent users x 3)



Try using another method of garbage collection,
if you're using JDK 1.4.1 i'd try either
ConcurrentGC with ParNewGC (ParNewGC on Multi-CPU machines):
-XX:+UseConcMarkSweepGC -XX:+UseParNewGC
or ParallelGC with AdaptiveSizePolicy (saves you the work of Java Heap 
usage analyzing :-) :
-XX:UseParallelGC -XX:+UseAdaptiveSizePolicy

A good article on GC can be found here:

With Tomcat 4.1.x

We've recently run into an issue where some of our pages either
a) take a really long time to come up (20+ seconds)   or
b) come up, but never really finish loading (the status bar in IE shows 
the the
response hasn't finished).

These are very simple pages (for example, a login page) and our server 
load is
minimal (maybe 10 concurrent users).  Then, mysteriously, the problem will go
away by itself.  It will also return.

Given the information above, I'm not expecting any solutions, but I could use
some help steering me in the right direction with things to check.  We're
hooking up monitoring on the systems (Linux) to examine memory and CPU
utilization during the slowdowns.
Any things in particular we should be examining to try to find the problem?
Any idea why the pages would never fully return from the server?
TIA

In a situation like that, the two things I check first are:

1) DNS lookup failing, especially a reverse lookup..do you have Tomcat 
trying to look up a hostname for access logging, perhaps?

2) database connection timing out

Also, I would look at garbage collection, but I doubt that's it.

Dual CPU, with both cpu's sitting at about 99% idle.  1 GB of RAM, and 
it's not even being all used.  Tomcat is using about 327MB of RAM with 
maybe 40(?) threads running.

When I submit my request to get the login page (not to process the login, 
just to serve the login page), I couple of the java threads will spin up 
and take maybe 3% of the cpu, but it still takes over 30 seconds to get 
the page.

Still stuggling for ideas.

Are these results occurring when tested on a local

I have had an issue like that, but it turned out to be
a networking issue..not tomcat.

do you have a proper WEB-INF

I mean, are all the letters uppercase?

Charles,

Try deploying it without the web.xml file.  

Can you maybe post the login.jsp file that you are trying to use?  I can
see if I can reproduce the problem on my machine.

Another thing that you may try doing is copying a directory in
\webapps\examples\jsp.  Just copy the directory right out into
\webapps\.  Then restart Tomcat.  If you get an error try putting
in a WEB-INF directory along with a web.xml file.

Subject: Need help on deploying application

I have installed Tomcat on my workstation and I'm able to access the
applications supplied with the distribution. I have two Tomcat books and
I'm trying to deploy an application from one of them as a tool to learn
Tomcat basics. I am unable to get to the application. Below is what I
believe to be the essential facts of my situation. I would appreciate
someone looking over this and telling me where I've gone wrong or
offering suggestions on other debugging techniques. Thanks.

Here is the information from the Tomcat Manager page:
Tomcat version: Apache Tomcat/4.1.24 
JVM version:
1.4.1_02-b06
JVM supplier:
Sun Microsystems Inc. 
OS:
Windows XP 
OS version:
5.1 
Processor architecture:
x86 

My CATALINA_HOME environment variable points to:
D:\Program Files\Apache Group\Tomcat 4.1

My application is at this path location:
D:\Program Files\Apache Group\Tomcat 4.1\webapps\apress

I have the files "login.jsp" and "welcome.jsp" in this directory.

I have this web.xml file in apress\WEB-INF:


http://java.sun.com/j2ee/dtds/web-app_2_3.dtd'>



  
login
chapter2.login
  

  
/apress
/WEB-INF/lib/taglib.tld
  



I have this context element in my server.xml file:


When I point my browser at "http://localhost:8080/apress/login.jsp";, I
get this error message:
"The requested resource (/apress/login.jsp) is not available."

When I use the Tomcat Manager application to start the "/apress"
application, I get this error message:
"FAIL - Application at context path /apress could not be started"

Can anyone point out where I've gone wrong? Thanks.
