Re: Tomcat has 2 webapps - confused which classes to load

The JVM *can* (and in this case, *does*) load classes with the same

the two different webapps).


The problem is with the Java debugging interface - it merely notifies 
the listener (Eclipse) that "a class named  has been loaded".


There is no other usable context to tell eclipse whether the  was 
loaded in package1 or package2, so it'll insert a breakpoint for each of 
them, and stop at each of them.


If *you* have a way of telling them apart, you can put that condition in 
the breakpoint, to only stop if that condition is true..

Tomcat has 2 webapps - confused which classes to load

[John MccLain]

I have 2 web applications underneath Tomcat/webapps. some of the classes,
such as the lifecycle listeners for both projects, have exactly the same
package/class names. I kick off Tomcat from eclipse, and put a breakpoint in
the lifecycle listener for project2. Project1 loads first, and eclipse
breaks  at the breakpoint I set for the lifecycle listener -BUT, it breaks
at that brekpoint in project1's listener, not project2 where I set it?!?
When I continue execution, and project2's context loads, it breaks at
project1's listener again?!? - it never breaks at the breakpoint I set in
project2, it only breaks at project1's
so my first question is why is the above happening?

OK...So, correct me if I am wrong, but is this because the JVM can't load 2
classes with the same package/class name? If this is so, then why does
Tomcat not add the application context name to the package name so there is
not a naming conflict?

so my second question is, is there a way to have a class called "aaa.bbb" in
WEB-INF/classes of both project1 and project2 unerneath Tomcat/webapps, and
have Tomcat (and Eclipse) recognize them as separate classes?

Thanks, you prompted me to give it a try :-)

The GNU Classpath implementation only supports Java 1.4 so you'll have
to stick with Tomcat 5.0.x for the time being.

The quick way to get going is to modify the _RUNJAVA variable in setclasspath.sh

_RUNJAVA="/usr/bin/gij "


If you want natively compiled classes you could try using the GCJ JIT
functionality described here (compiles the classes on the fly):

http://gcc.gnu.org/ml/java/2005-06/msg00045.html

Just extend your gij setting in setclasspath. If it works it will take
a _long_ time to start as it compiles all the classes (but they will
then be in your cache for the next restart). When doing this I got a
"too many root sets" error. YMMV

To natively compile the classes first and then run Tomcat use the
script from here -
http://developer.classpath.org/mediation/ClasspathShowcase#head-7d9a556e8485fc84fd5ce0e52be6104d85e24316
- and wait ;-)

Finally change you gij arguments in setclasspath to include
-Dgnu.gcj.precompiled.db.path

This worked for me (at least I assume it did!).

If you get it going and have any opinions on performance I'd love to hear.

Sure you can pawn off the processing to other
processes.  It's still going to use memory and the
processor regardless however.  This would at least
leave your main process memory for handling requests. 
You could also look at your long running memory
intensive operations and see if you can move this out
to some type of a stream operation or something and
move the data holding and manipulation to random
access files or a database.  Unless you are really
doing something that "really" requires heavy lifting
you should be able to refactor your code to handle the
load better (300+MB of RAM is a lot if this is per
thread/actionnot so much if you are talking about
the server process using more than 300 MB of RAM).  If
not then your processing requires resources and it's
time to up to a real multi-processor system and throw
gigs of ram on to it or cluster and make sure you have
enough RAM on each machine to handle the memory usage.
 No matter what software you're using the hardware has
to support the work load.

RE: Managing concurrent high memory processes

[Duan, Nick]

You may want to find out where the bottlenecks are before deciding on
clustering or lb tomcat.  For instance, if the bottleneck is your
backend database, clustering tomcat won't help at all.  One easy way to
find out the bottleneck is to turn on the debugging or just use the
operating system monitor to monitor the CPU utilization (assuming tomcat
and the backend database are on different machines).

We have a Struts application running on Tomcat where a few actions

several hours. The issue is how to make the application more scalable to

accommodate multiple concurrent 'high load' processes and also make

Would Tomcat clustering/load balancing be suited to this problem? Or is
it 
more geared to managing high volumes of requests rather than just
dealing 
with certain high load requests that need special attention?

We have also considered spawning a separate jvm instance (or retrieving
from

RE: Managing concurrent high memory processes

[Richard Mixon]

BB,

It sounds like you are talking about what used to be called "batch
processing". The workload is simply kicked off from a web request. Does it
(attempt) to return a request to the user? Are timeouts and issue?

As far as available RAM - the obvious solution here is to move to a 64-bit
OS. We've been using AMD Opterons and SuSE Linux for high-memory Tomcat (JVM
heap > 2GB) for a couple of years now. But I'm also running Windows XP _64
on my desktop and its JVM seems able to take more than 2GB also.  We have a
somewhat similar problem, in that we have to dynamically build an in-memory
"cube" of analytical data for charting and what-if exploration of
results.But our reponses typically come back in between 15 seconds and a
couple of minutes.

Depending on how large your session is, you may not really want to use
clustering - because your sessions are replicated across all or a subset of
machines. 

However simple load balancing with session affinity might help you scale
your solution - either with multiple Tomcat's on a single machine or on
separate machines.

But ultimately, I think you are going down the correct path to consider
spawning a separate JVM to handle this if it is a true "batch request". From
what I know (please correct me if I'm wrong here) Tomcat is definitely
optimized for handling larger numbers of "relatively" small requests. Its
also much easier to tune Tomcat if you have a larger numbers of similarly
sized workloads (requests). On mainframe transaction processing the analogy
was to an hour glass - if you mixed a few pebbles in with all of the grains
of sand, you ended up clogging up the works for everyone - not just
yourself.

This also lets you allocate CPU resources to these separate JVM as you wish
- if its all in Tomcat, you have much less control.

Also, if communication has to occur back to a Tomcat user, you might
consider using Java Messaging Service for this - at which point you should
look at Jboss or similar application server that has Tomcat and a JMS
bundled together.

Hope these thoughts are useful.

 - Richard

Re: Managing concurrent high memory processes

[Peter Lin]

sounds like you have a heafty reporting process, which loads a ton of data
and generates a large report. I definitely wouldn't recommend running these
processes within a single instance of Tomcat. You'll easily eat all the
available RAM and get OOME.

A better approach would be to off-load the process and use something like
JMS to route the message. If the process is generating a report, I would
recommend revisiting the design and implementation of that component. More
specifically, if you're running all sorts of multi-dimensional reports on a
large dataset that's 500K+ records, consider using an OLAP product. In many
cases, using MOLAP approach can reduce the processing time by 10x.

good luck

peter

Managing concurrent high memory processes

[BB Commish]

We have a Struts application running on Tomcat where a few actions within 
the app can invoke processing that consumes 300+ MB of RAM and can run for 
several hours. The issue is how to make the application more scalable to 
accommodate multiple concurrent 'high load' processes and also make better 
use of servers with available RAM beyond the jvm limits (we have used both 
Sun and JRockit jvms - typically on Win2k3 as per customer requirements).


Would Tomcat clustering/load balancing be suited to this problem? Or is it 
more geared to managing high volumes of requests rather than just dealing 
with certain high load requests that need special attention?


We have also considered spawning a separate jvm instance (or retrieving from 
a pool more likely) to handle each high load request with the 'normal' 
requests being handled within the jvm running Tomcat. Is this a feasible 
option?


I will appreciate any comments. Thanks.

How do I force getContextPath to return ""

[hv @ Fashion Content]

Is there a way have getContextPath return "" other than setting it up as 
ROOT context

I seem to remember  working, but it 
doesn't seem to have any effect in 5.5.9

I have that old problem of rewriting URLs to get rid of the pesky context

Security not on, so why do I get an AccessControlException?










It is my understanding that when you start Tomcat (version 5.0.28
customized for Liferay portal) from the command line (Windows XP Pro) via
the startup.bat with no parameters you do not have security turned on.  In
order to use catalina.policy I would have to run "startup -security"  Since
I'm not doing that I'm confused on why the following message is showing up:

This happens when I attempt to add a portlet that requires an EJB from
WebLogic.  I can add and run other portlets without causing the error.

I have tried running with security and received the same error.

Also tried to create a policy called wideopen.policy that contains the
following:

grant {
      // Allow everything for now
      permission java.security.AllPermission;
};

Then changed the catalina.bat to use wideopen.policy instead of
catalina.policy.  Still I end up with the same error.

Please help me understand what is happening

OK, the problem was exatly the reverse, the classes (jars) of shared/lib 
didn't find log4j and the ClassNotFoundExcepcion was caused by that.

Something strange happened to my tomcat yesterday:

I have two webApps which use some shared jars that i put in 
$TOMCAT_HOME/shared/lib


Yesterday i decided to remove the log4j.jar from shared/lib and put it on 
each webApp WEB-INF/lib dir.


Log4j works great now, and one of the WebApps also runs fine. But the 
other can not find any of the classes of the jars that remain in 
$TOMCAT_HOME/shared/lib


I had to put ALL the jars of shared/lib in this WebApp WEB-INF/lib/ dir to 
make it work.


Any suggestions to try to find why this is happening?

The conventional Java approach of using your domain name to ensure the
uniqueness of package names applies just as much in Tomcat as everywhere
else.  I've only needed to break that once, when I was hacking at some
Tomcat internals and needed access to some classes that only had package
access.

Tomcat and Lomboz: access to SQL drivers?

[Thomas Nybro Bolding]

I am building a project using eclipse and Lomboz for Tomcat 5.5 in which I 
need to access a SQL server.
In the project web.xml I have added resource-ref as I would on the Tomcat 
server. On Tomcat I would then modify the context xml file in 
conf/Catalina/localhost and add Context and Resource parameters. But where 
does this information go in Lomboz?
I have added the Tomcat server to my Lomboz project and thus have a 
directory containing a server, tomcat-users and web.xml files. From this 
directory I am able to launch my project locally but can not gain access 
to the SQL server as Tomcat reports "Cannot create JDBC driver of class '' for 
connect URL 'null'". I have tried to add the resource parameters to the context 
element in 
server.xml as well as add a global naming resource but in either case 
Tomcat refuses to start locally?

Any help is highly appreciated as I'm pretty noob when it comes 
Lomboz/Tomcat integration...

Best regards Thomas

jsp pages do not run in tomcat

[Aparna Ramakrishnan]

  Hello,
  I am running tomcat4. when i start Tomcat using /etc/init.d/tomcat4 start 
using JAVA_HOME=/usr/lib/kaffe, tomcat stops to run almost immediately but says 
the pid file still exists.
   
  Now if i export JAVA_HOME=/usr/j2sdk1.4.2_09, and start tomcat again, it runs 
comfortably.
   
  But when i run jsp pages, on the browser, i get the following error.
   
  type: Exception report

cross context failing on Tomcat 5.5.9

[irene_hall]

Cross context failing on moving from Tomcat 4.1.27 to 5.5.9
I have an application which consists of several application wars all within
the same virtual host. Each application is configured with the same servlet
filter which gets the context for the main part of the application.
I have crossContext="true" on all the context elements. The context
elements are each in a .xml where  is their app name and the
root context is in ROOT.xml. They are all under
Catalina_Home/conf/engine_name/host_name/*.xml
This application works fine on Tomcat 4.1.27 and fails on Tomcat 5.5.9. It
is failing at the point where the filter attempts, from within its own
servlet context to getContext(name) - that call returns null every time.

What am I doing wrong ? Am I missing some configuration element ?

Irene

Shared/WebApp ClassLoaders

[Andrés Glez .]

Something strange happened to my tomcat yesterday:

I have two webApps which use some shared jars that i put in 
$TOMCAT_HOME/shared/lib


Yesterday i decided to remove the log4j.jar from shared/lib and put it on 
each webApp WEB-INF/lib dir.


Log4j works great now, and one of the WebApps also runs fine. But the other 
can not find any of the classes of the jars that remain in 
$TOMCAT_HOME/shared/lib


I had to put ALL the jars of shared/lib in this WebApp WEB-INF/lib/ dir to 
make it work.


Any suggestions to try to find why this is happening?

OS: Debian 3.0
Tomcat: 5.0.28
JDK: 1.4.2_09

Thanks

RE: session replication errors

[Richard Mixon]

And does this have to do with "session replication errors"?

At least when hijacking a thread remember to change the Subject line. But
better still create an entirely new email and address it to the list. This
will make it easier on those of us that use threaded mail readers.

Concerning your question. Are you using the Sysdeo Tomcat plugin or WTP? If
using Sysdeo, I am using Eclipse 3.1 and Sysdeo and its works fine either
way.

Please also tell the operating system and version and Java version - it
might help.

HTH - Richard

Re: Tomcat 5.5 problem - container not serving up web content

[Michael Niemaz]

I have the same message when I try to deploy a war file that already exists.
I have to shutdown, remove the old war file and its deployed dir, copy 
the new war file and then re-start Linux Tomcat.

This probably has nothing to do with your problem but ... we never know ;-)

I believe this to be a config issue, but have had no success resolving it 
for the past two days, so any help would be greatly appreciated.


When I access a JSP page directly on my localhost, it loads properly with 
images and the stylesheet.
However, when I access the JSP (or any other JSP for that matter) using a 
filter, servlet or the struts action forward, the JSP content loads up, 
but anything else (images, linked CSS files) do not get served up. 

I've tried every single variation of the  and  tags (relative, 
hardcoded, with a /) but that didn't work. My guess is that there is some 
additional configuration that I haven't completed, yet I don't see if 
anywhere in the docs. I tried adding MIME mapping info to my web.xml, but 
that didn't help either.


The only possible relevant info that shows up related to errors/warnings 
is the following log:
   "Nov 17, 2005 1:50:23 PM org.apache.catalina.startup.ContextConfig 
applicationWebConfig
   INFO: Missing application web.xml, using defaults only 
StandardEngine[Catalina].StandardHost[localhost].StandardContext[]"
My web.xml is located in \Web Content\WEB-INF\web.xml, which sounds like 
it should be ok.



Using Tomcat 5.5 on jdk1.5.0_05 and developing on Eclipse 3.1 with the Web 
tools project 0.7 and no other plugins. 


Please help me out if you know what's up.

TIA!
JR

Did you set jvmRoute on both tomcats to distinct values? By default it is 
not specified on the Engine element in the server.xml.
