Re: Unable to run tomcat

This could mean that a previous startup is still busy, or that you
actually have another tomcat running on the same machine?

I would suggest rebooting, starting tomcat, and monitoring the logs very
closely.

Re: Tomcat5 installation problem

[Oguz Yarımtepe]

Changing the port solved my problem. Thanx.

2006/7/14, David Smith <[EMAIL PROTECTED]>:

Port 8005 which tomcat uses as a shutdown port is in use by another
process. You could change that in server.xml or shutdown the service on
8005 to fix it.

Tomcat is (very!) multi-threaded anyway.  If you want to run multiple
web applications (.war files), simply put all the .war files into
Tomcat's 'webapps' directory.  Tomcat will start and run all of them,
and will allocate its threads to whichever web applications need them at
the time.

Does this help?

And
netstat -ano -p TCP

Re: Patch to override request.getRemoteAddr if behind a reverse proxy

Hi

We needed to patch Tomcat for our site that has a Tomcat
behind Apache (mod_jk), that sits behind a reverse proxy load balancer.
The idea is basically to not use the TCP endpoint of Apache (which will
always point to the reverse proxy) to give the caller of
request.getRemoteAddr a valid IP, but rather retrieve it from a
configurable request header. In our case, we have hacked the Pound
loadbalancer to forward a request header called X-Pounded-For with each
request, and the value of this header is then used (if available) to
return the *real client IP to the caller of request.getRemoteAddr or
request.getRemoteHost.

Extract from server.xml:

In stead of patching Tomcat, you can also make a util class/method like this.

public final class ServletUtils {
   private static final String MY_TRUSTED_PROXY = "127.0.0.1";
   public static String getRemoteAddr(ServletRequest req) {
  String remoteIp = req.getRemoteAddr();
  if (remoteIp.equals(MY_TRUSTED_PROXY)) {
  String proxyIp = req.getHeader("X-Pounded-For");
  if (proxyip != null) {
 remoteIp = proxyip;
  }
  }
  return remoteIp;
   }
}


This makes your application know about your setup in stead of Tomcat. Much more 
flexible and much less problems when upgrading Tomcat.
You can also put this in a Filter which wraps the ServletRequest with your own 
version. This keeps your application clean and it just uses the standard 
Servlet extendabilties.

Re: Patch to override request.getRemoteAddr if behind a reverse proxy

[Johan van den Berg]

Except that I have 5 servers, each having 20 different apps, some of
which are 3'rd party, so I *really* don't want to modify the app (closed
source).

This is a server infrastructure and configuration issue, none of which
any developer should ever be worried about...

Hello,

Use the method ServletResponse.setCharacterEncoding("UTF-8") in a Servlet or 
contentType="text/html; charset=UTF-8" in a jsp page.
http://java.sun.com/products/jsp/syntax/1.2/syntaxref1210.html#15653

But charset issues are tricky because all you files need to use a known 
charset. And if you use a database it needs to have a supported charset also.
If your editor saves files in iso-8859-1 the problem is already there and the 
browser wil never see the right character. So you need to debug where the 
character is correct for the last time.

A Filter is really good to use in that case and if I remember correctly you can 
add it to conf/web.xml. Or you can create a Valve for Tomcat and put the code 
in there. Tomcat is already extendable without using patches.

Re: getting "?" instead of "¢"

This is not a matter of saving the jsp/html file on server with the good 
charset, this is a matter of using the correct entity reference (¢) 
which is supposed to be displayable by any html 2.0 compliant browser.

Re: Patch to override request.getRemoteAddr if behind a reverse proxy

[Johan van den Berg]

I'll accept as much, but understand that I just followed the same
approach that was taken with the proxyName and proxyPort parameters that
already solve a similar problem in Tomcat when sitting behind a reverse
proxy.

If that problem was solved with a Filter / Valve, I would have done the
same with my approach...

There are more possibilities for the same thing. In the original question there is 
no mention about where the character is coming from. If it is something an user 
submits in a form and is stored in the database and then displayed in another 
webpage you can not asume the user to type ¢.

Hello,

Use the method ServletResponse.setCharacterEncoding("UTF-8") in a Servlet or 
contentType="text/html; charset=UTF-8" in a jsp page.
http://java.sun.com/products/jsp/syntax/1.2/syntaxref1210.html#15653

But charset issues are tricky because all you files need to use a known 
charset. And if you use a database it needs to have a supported charset also.
If your editor saves files in iso-8859-1 the problem is already there and the 
browser wil never see the right character. So you need to debug where the 
character is correct for the last time.

Ronald.

It is.

Using an entity reference is just one way to get "special" characters 
transmitted to the client. But this will only work if this entity reference 
is defined/recocgnized/interpreted in the output format used - for example in 
HTML. For other output formats - for example plain text - this will obviously 
be useless.
Since - in my experience - modern clients on modern OSes can handle correctly 
encoded input just fine (if they are told how it's encoded), I see no general 
need to cope with entity references. It all boils down to the fact that the 
encoding declared in the HTTP header and the encoding actually used have to 
match.

So I'd also stick with Ronald's proposal and create correctly encoded output.

The following - if saved as UTF-8 - should work as expected:

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>




Display a cent


These are two cents: ¢ ¢



BTW: it isn't strictly neccessary to use UTF-8. Using a charset that contains 
all symbols used is enough. This mail for example should use ISO-8859-1 as 
charset and still contain the literal cent sign above correctly encoded.
Nevertheless I'd prefer UTF-8 on the web as a more universal approach.

Wrong. My mail client chose to encode it in UTF-8. But that doesn't change the 
fact that ISO-8859-1 contains the ¢ sign at position 162.

RE: Tomcat Not An App Server

[Mike Wannamaker]

I would love to just use JBoss, but there is a lot of political red-tape and
we even have our own App Server, which too is not J2EE compliant.  It was
probably developed before JBoss and the like.  We even had our own Web
Container, but I've recently replaced it with Tomcat.

What I've done is ripped out our core services from our internal app server
and provided an app server connector layer.  The idea is that we'll be able
to plug into any app server like container.  Our own internal, JBoss,
WebSphere, Tomcat???

That is the idea.  So we have customers that may have tomcat installed and
perhaps they would like to utilize that instead of installing another app
server.  So I would like to be able to somehow have Tomcat start our core
services, much the way that JBoss would, before loading any web apps.

Does anyone have any ideas on how that could be accomplished.

Sorry guys I didn't mean to offend anyone.  I know that Tomcat offers a lot
but what I meant is as you said, it's not a full J2EE App Server, like
JBoss, WebSphere ...

What I have is a large enterprise application that does have a web
application.  In fact it has many.  These web apps rely on our core
services
to be running.  Within JBoss etc I can install this as an EAR or SAR and
JBoss will start it.

I was wondering if there is anything in Tomcat like that, were my Core
Services could get loaded/started before the tomcat web container loads the
web apps.  Thus I wouldn't have to code anything into the web apps
themselves to try and start it.

Tomcat's not really an app server?  Geee really, I feel so inadequate

Seriously, I think I've seen this religious war around here somewhere
and it really depends on definition.  No, it's not a full J2EE
container, but it's definitely an app server in my opinion.

Have you read the servlet spec and thought about the
ServletContextListener for handling the start/shutdown of a component
within your app?

My guess (which should be taken with a grain of salt, as I'm  
relatively new at this myself) is you want to subclass StandardHost  
or StandardEngine, and have the start() method initialize your core  
services, and the stop() method shut them down.


If subclassing those is as easy as subclassing StandardContext was  
for me, it should be as simple as calling super.start() and super.stop

RE: Tomcat Not An App Server

Thanks Timothy,

I'm actually looking more for a way to do it with Tomcat out of the box.
Like if a customer has Tomcat installed, I would just want to put my jars
into some lib directory and then add this ??? entry into this ??? xml file
and it will call start() on your class?  

Would it be possible for me to have a Valve to do this?  Forgive me for my
ignorance, but I don't know the tomcat architecture that well yet, just what
little I've read.  As long as it starts before the web apps that is all I
need.

If I understand everything correctly, when Tomcat receives a
request it creates a new thread and runs the servlet in that
thread that matches the servlet or JSP requested.

Multiple requests can be processed concurrently, whether they are
requests for the same servlet or for different servlets.

Each thread will normally get its own stack for automatically
allocated variables and objects.  Depending upon how your program
is written however, it is possible for the threads to interfere
with each other if they use any static variables - so you must
use synchronization if it is required.

jsp compilation error in tomcat

[Suba Suresh]

If this is the wrong group to post this question let me know. I am new 
to jsp.


I am using Tomcat 5.5.17. I am using the jsp pages that came with 
lucene. When I am trying to access the results.jsp file on Tomcat I am 
getting the following error. I looked at the jsp code I am not able to 
find anything wrong. The code snippet is below the exception.


org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 120 in the jsp file: /results.jsp
Generated servlet error:
String literal is not properly closed by a double-quote



Document
Summary


<%
if ((startindex + maxpage) > hits.length()) {
thispage = hits.length() - startindex;  		 
  //set the max index to maxpage or last	  //actual 
search result whichever is less	

}
%>   

Any help or suggestion is appreciated.

thanks,

Re: multiple t hreads

[Alan Meyer]

> with tomcat if so how

This can be done in the normal way.  Your servlet can start
separate threads, each of which runs somewhat independently.

However, there is a problem with this if you are intending to run
a thread in the background while returning information to the
client in the primary thread.

When I tried to do that on older versions of Tomcat (4.x), all
output to the user was suspended until _all_ of the threads
completed.  So you can't use this technique to run a batch job on
behalf of the user.  In fact, running a long batch job will time
out the webserver and abort the job.

What I did to overcome that was to spawn a new Java virtual
machine that ran apart from Tomcat.  To do this, I used an open
source routine by Marty Hall.  You can exec "java classname" or
exec a shell script or batch file that starts the JVM.

See: http://www.apl.jhu.edu/~hall/java/Exec.html

Re: Tomcat on a server

[David Smith]

Yes, but  Tomcat also pools threads and keeps them around between 
requests, recycling as necessary.  The servlet's themselves should avoid 
class instance variables unless they are reset to some known state at 
the beggining or end of every request for this reason.

Each thread will normally get its own stack for automatically
allocated variables and objects.  Depending upon how your program
is written however, it is possible for the threads to interfere
with each other if they use any static variables - so you must
use synchronization if it is required.

Class instance variables must be synchronized to be completely safe, or kept
in ThreadLocal objects.  Unless you implement the SingleThreadModel
interface, in which case Tomcat will not run concurrent threads through your
servlet.  Otherwise, two threads can easily get in each other's way
accessing instance variables.

That is perfectly reasonable.

Here's a suggestion: create a new webapp that doesn't actually have any
servlets. Just create a ContextListener that responds to START and STOP
requests, and use the listener to startup your services.

web.xml in each webapp can specify the order of servlets coming into
service... I'd imagine that Tomcat can be configured to load this
"services" webapp before all other webapps are loaded, so that those
services are available.

Would this meet your needs?

This was probably due to mismanagement of the thread; a new thread will
run independently of your request handler thread, unless you call "join"
on that thread, which will block the current thread until the "joined"
thread completes.

You /can/ do a batch job on behalf of a user -- you just have to be
careful about it. For example, a user RELOADing the page many times will
spawn many threads on your server, which represents a potential DoS
risk. Resource management (such as threads) is usually best left to the
container unless you really know what you're doing.

This is arguably worse than spawning a new thread to do this kind of
thing: you are subverting Java's protections and essentially allowing a
user to create a new process on your server.

You are better off creating a thread pool and re-using threads to
complete long-running operations. You can have your long-running thread
write some status to somewhere convenient (such as the user's session)
so that subsequent requests can display some kind of status information
each time. There's no need to worry about request timeouts, etc.

If possible, a better solution would be to actually run the batch job
/as a batch job/ -- i.e. store the job in a database/file/whatever, and
have another process come along and process that request as necessary.

This is all academic, since I think the original question was something
along the lines of "Does Tomcat actually work like an app server should?
with threads and everything? Does it?!".

Your code snippet does not seem to contain the action error ("String
literal is not properly closed by a double-quote"). Try looking around
your code for a place where you tried to define a string, but forgot to
put a " at the end, like this:

String foo = "bar;

String foo = "bar";

RE: getting "?" instead of "¢"

why don't you manually write it to your page and then just have the variable

 There are more possibilities for the same thing. In the original question 
there is no mention about where the character is coming from. If it is 
something an user submits in a form and is stored in the database and then 
displayed in another webpage you can not asume the user to type ¢.

Look in the web.xml file. Perhaps within servlet mapping is what you're looking 
for?
At least it's that way in Tomcat 4 series.

How to log and debug Realm Authentication in 5.5.17?

[David Erickson]

Hi I am running two hosts under an engine in Tomcat 5.5.17, I have one
webapp on each host and am having some problems with authentication on both.
Each has a jdbc realm being deployed by a context.xml file in the META-INF
directory of the webapp.  

My question is, how can I log and debug the deployment of each realm and its
properties, and subsequent login attempts/rejections, and their JDBC SQL
queries etc?

RE: NEW : Tomcat Performance Monitoring

[Sharma, Siddharth]

Pls look at the man pages and decide what you want.
You should probably pipe the output of these commands to a log file, so it
is running all the time and logging to a file and then whoever needs to see
this info, simply tails the log rather than running another sar or vmstat
session.

Ex. Vmstat gives you a bunch of information such as CPU idle % time, system
and user CPU utilization, paging, I/O Wait etc. You can pick and choose.

You can use sar or vmstat
They give you system level health.
If you need inside the jvm health you can run the jvm in hprof mode. It 
adds
plenty of overhead so beware.

I am using Tomcat 4.0.6 in a Vignette content management application.
I need to monitor Tomcats performance real time.
Could someone suggest any answers?
Up till now, the only sure way was to do a kill -3 JVM-PID and get a

which gives ample information but it is post-incident.
Are there any tools I can download and use or any commands someone can

RE: Tomcat Not An App Server

[Mike Wannamaker]

I believe you and Martin are saying the same thing.  I could do that however
I would need my jar file to be in $TOMCAT_HOME/shared/lib probably.  I can't
have each different web app starting new instances of the services.
Services are only started once be Tomcat Server.

I thought maybe it was possible to add something to server.xml to get a
component to startup.  Perhaps I'd have it implement a Tomcat Interface but
I could do that and then have it only start once per Tomcat Instance.

Either way I need my jar in $TOMCAT_HOME/shared/lib.  That is the one I put
it in right?  Not $TOMCAT_HOME/common/lib?

That is perfectly reasonable.

Here's a suggestion: create a new webapp that doesn't actually have any
servlets. Just create a ContextListener that responds to START and STOP
requests, and use the listener to startup your services.

web.xml in each webapp can specify the order of servlets coming into
service... I'd imagine that Tomcat can be configured to load this
"services" webapp before all other webapps are loaded, so that those
services are available.

Would this meet your needs?

No, in fact it's better if you /don't/ have your JAR file in
TOMCAT_HOME/shared/lib: you want a completely separate webapp. You can
even put it into a WAR file and drop it into the auto-deploy directory
if you have Tomcat to auto-deploy WAR files.

In this way, you have a completely portable webapp that simply does not
have any servlets running within it. The only trick is to get Tomcat to
load that webapp /before/ any other webapps start.

One option is to startup a separate instance of Tomcat for the purposes
of only hosting this services webapp, and run your other webapps however
you wish. You simply have to start the services instance of Tomcat
before starting any other instances. This strategy also allows you to
bring your services up and down (possibly for an upgrade) without
disturbing the dependent webapps.

Don't let the term "webapp" get in the way... your services (JMS or
something like it?) will be available just as you are accustomed to
having them. You are only adding a thin layer (the ContextListener) to
get them started within Tomcat -- because it does not have some of the
features aforementioned app servers.

If you want something to start before all the other webapps, my

If you are willing to modify server.xml, then you can probably write

might be able to do the same with a Valve: I'm not sure as I've never  
worked with Valves.


Either way, it should, indeed, just be a jar you drop into common/lib  
and an attribute you add/change in server.xml.

The desired outcome is to have something that can start up as soon as  
Tomcat is started, rather than on the first client request, and not  
be attached to any particular webapp.  At least, that's how I see it.

Shared code but different pages on different virtual hosts?

[Harris, Thomas]

I have been trying to determine how to configure Tomcat 5.5.17 to have a
shared appBase on multiple webapps, but have a different set of JSPs for
each web app. I've followed the Wiki's CreateVirtualHosts page to
configure multiple webapps that use exactly the same WAR file. But, I
would like to share the Java, but supply a different docBase for each
site. Is this possible?

Reference:

Re: How to log and debug Realm Authentication in 5.5.17?

[Martin Gainty]

Looks like you'll have to implement a customised JDBCSecurityRealm such as what 
you see here

http://www.trifork.com/package/eos/external/static/T4/doc-4.1/documentation/userdoc/html/ch32.html
overriding the important access points such as all access(es) by implementing 
your own override of JDBCSecurityRealm
to (possibly your own base class) underlying principal javax.security.Principal

so when your own JDBCSecurityRealm authenticates the supplied username/password 
via the method
public Principal authenticate(String userName, String password)
throws LoginException {

your catch clause for 'LoginException' would write to Log4j..

Re: multiple t hreads

Chris,

Thank you for the excellent advice and suggestions.

I take it you've actually tried this and it worked for you.
Which version of Tomcat were you using?

I'm positive that I didn't call join to wait for completion of
the threads that I started.  Is it possible that earlier versions
of Tomcat did that beneath the covers, or perhaps that this was
configurable and our systems administrators (I wasn't
administering Tomcat myself) forced this to happen?

I agree that my technique was worse than spawning a thread.  I
didn't want the overhead of running two JVMs.  But, try as I
might (and I tried mightily hard), I wasn't able to make it work
on the installation of Tomcat that I was using.

I only allowed one batch job to run at a time, for just the
reasons you mentioned.  I wasn't worried about a malicious denial
of service attack since our server was running on an intranet for
vetted users, and I wasn't concerned about starting arbitrary
jobs since the users could only pick from my menu of jobs to run.
But I was worried about a user starting a long running job, not
seeing results right away, and starting it again and again.

> You are better off creating a thread pool and re-using threads
> to complete long-running operations.

Is this just to limit the number of threads that can run?

I wouldn't be much worried about the overhead of starting a new
thread since I already know I'm running a batch job which is
going to take a long time.  Starting a new thread is in the
noise, performance wise.

That's a very neat idea!  I never thought of anything like that.

Another excellent idea.  I thought of it and have used it on
other projects but, alas, the sys admins hated the idea of
running another daemon and I didn't want to fight with them.

> This is all academic, since I think the original question was
> something along the lines of "Does Tomcat actually work like an

Well, the original poster may not have learned anything from
this, but I certainly did.

Thanks again.

I can't recall what we were using on some of our development servers
(probably 4.1.something), but we were running Weblogic in production. We
used our own simple thread pool and it worked great. Our "batch job", as
it were, was actually opening an FTP connection, pushing a handful of
files through it, and notifying us of its progress during the whole thing.

The previous implementation was synchronous, and (as someone pointed
out) the request can time out if it takes too long. We modified this
process to use a background thread and an auto-refreshing page that
refreshed every couple of seconds. It actually made for a relatively
good looking progress bar.

I think that it was unlikely that Tomcat did anything like that; Tomcat
doesn't manage /all/ threads in the system... only the request handling
threads. Perhaps something else was happening. Were you writing to the
response in that thread that you created? That could cause some odd
things to happen...

That's too bad. I don't recall having too much trouble when we did ours.
I argued with the engineers that we couldn't write a decent thread pool
fast enough and ought to get something off-the-open-source-shelf. I lost
the argument and we wrote our own simple one.

That was probably a good move. We were dealing with several dozen users
on each machine, across 6 production app servers. Our peak load was
about 100 users/box every morning, so we weren't really excited about
/potentially/ starting 100 (or more, in case we mismanaged RELOADs) new
threads to handle these FTP transactions. At least those operations were
relatively infrequent.

>> You are better off creating a thread pool and re-using threads

> Is this just to limit the number of threads that can run?

Yes. In fact, some thread pools are written to act like batch processors
(I think that .NET comes with one such implementation): you create a
Runnable object and basically queue it into the batch processor. The
batch processor then attaches a thread whenever one is available. That
Runnable object could still report status information to the session, etc.

So, if you only had a single thread in your thread pool (a "shallow"
pool, if you will), and high demand for batch jobs to be run, most
clients would sit around refreshing their pages simply saying "waiting",
since the job hadn't started. One lucky job would get done, and then the
rest would follow.

Refreshing pages aren't too much load, as long as you don't have a ton
of work to do in order to display them. For example, if you keep all the
information in the user's session (and the updated status information in
there, too), then you do very little work to spit out a status page each
time.

Agreed -- as long as you are managing those resources and not letting
many threads get started. You mentioned that you already protected
against that.

Subject: Re: Increase Heapsize


Hello.
I am using Tomcat 4.0.6 on the server.
I need to increase the heapsize.
Questions:
I've been receiving java OutOfMemory errors several times when a user 
attempts to upload files.
Is this enough to increase the heapsize as a 1st step?
Also how to go about doing it?
Do I simply increase the value after 'Xmx' in the JAVA_OPTS variable in 
catalina.sh file?
Or is there a export function?
Do I simply restart tomcat for the increase to take affect?
How can I monitor the application after the increase has been made?


Thanks,
Ibrahim

problems getting jkstatus to work in mod_jk

[Bob Jaques]

I am using apache to load balance apache/tomcat servers

I am trying to add jkstatus. It works fine until I enable the line in 
workers.properties enabling jkstatus then I get
"The server encountered an internal error or misconfiguration and was unable to 
complete your request."
When I access http://mywebsite.com/status/ but http://mywebsite.com/trader-web/ 
works fine. I cannot 
Find my errors also is there a way to eliminate the last / on trader-web to not 
be required

Thanks

RE: Increase Heapsize

[Ibrahim . Siddiqui]

I've increased the heapsize in my development enviroment.
And I don't knowhow to confirm the change has been made to the effect the 
whole system is affected.
So I'd like to know how to go about confirming this, possibly thru some 
monitoring measure.

Before I move to production I'd like to be certain that a simply edit of 
one line from one file and restart of tomcat would do the job.

I thought maybe it was done in the startup.bat file by changing the 
properties and the initial environment space (defaulted usually to Auto ot 

4096).
Is this not correct? 
You might try right-clicking startup.bat, and under the Memory tab try 
changing the expanded memory or extended memory values if they're 
defaulted to a certain value?

symbolic links usage

[Phill O'Flynn]

  I have a web app that needs to access
directories outside of the context using symlinks. However these files are not
visible to the servlet. I have looked at all the FAQ's and made the recommended
changes but it still doen't work. I am using Tomcat 5.0.XX

i have a
context.xml file setup in the webapps META-INF directory as recommended for 
tomcat 5
on the web site. This is my context.xml 




 

this is the
error I get

org.apache.jasper.JasperException: /dwgList.jsp(12,0) File
"/downloads/info.jsp" not found

("downloads" is a
symbolic link and is a sub directory of the project directory)

and this
is the calling code

<[EMAIL PROTECTED] file='/downloads/info.jsp'%>

Tomcat 5.5/Axis 1.4 java.lang.reflect.InvocationTargetException

[Luis Rivera]

Hi Tomcat users,

I have a web service which will JNI to access the application, which
according to the documentation should be placed in the shared/classes
directory. I did so and I got a dreaded
java.lang.reflect.InvocationTargetException, which I believe is a class
loader problem. However, I have tried to solve this placing it in the
common/classes, server/classes and I get the same result.

I have searched the web for solutions, some people say that it is a
classpath problem, but nobody seems to let you know where exactly you set
this so that the correct class loader finds the class (assuming I am right
and it is a classloader problem).

Anyone here can help me? If have had a similar setup/problem and have a
solution at hand?

Thanks in advance,
--Luis R.

RE: Tomcat 5.5/Axis 1.4 java.lang.reflect.InvocationTargetException

[Tim Lucia]

Please post a full stack trace.  TargetInvocationException should have an
underlying cause associated with it, like NullPointerException or
ClassNotFoundException.

[Luis Rivera]

  Thanks for the reply Tim,

Here is the stack trace, it does not look to me like it gives enough
information. Of course I am just starting with Tomcat and have some blanks
in my brain. I know is the classes are being found, either under commons or
shared classes directory, because if I just delete the classes then what I
get is a ClassNotFound exception, while if I place them under any of those
directories, I get the following exception:

Share context classes: Possible?

[Foo Shyn]

Hi guys,

This may sound dumb. Just wanna double check whether Tomcat provide sharing 
function where an application under a context could use a class that sit inside 
another context. I understand that for classes that need to be use by all 
application i'll need to jar it and put inside common\lib, but i'm wondering 
whether i could share out the classes in one of the context as a general 
application.

Thanx.

FooShyn

No, this isn't right: the properties you are talking about are for the
batch process itself (on a win32 machine). When startup.bat calls
"java", those values are not inherited by the VM.

This ought to work for you.

Although it is not unheard of to legitimately run out of memory (i.e.
get OutOfMemoryErrors), you ought to think about whether or not
increasing your heap size is actually going to fix your problem: often,
you have a memory leak and it's better to test your app with a small
heap because you can find it more quickly (i.e. less memory to burn
through before you run out).

I strongly advise you to critically examine your code to determine if
the OutOfMemoryErrors are being caused by you, or if you really do just
need more memory allocated to the JVM.

You can always call Runtime.getRuntime().totalMemory() to find out the
amount of heap space that has been allocated to the JVM. I have
incorporated this piece of information into a page that allows the
current user to "snoop" their session (only enabled in development, of
course).

Using -verbose:gc will also help in finding out the heap size
