Re: Image Scaling Code

[Ben Kim]

Sorry, a correction to my post. I checked my server and found that Xvfb is
actually running on display 1.0. These are the processes.

Xvfb :1

bash -c export DISPLAY=:1.0; . /opt//tomcat.sh 

I'll have to dig up for the details of tweaking, but googling of "tomcat
xvfb" turned up a few like this.

This may or may not be the case with you.

I had a similar error (X11, DISPLAY) with an earlier version of tomcat
included in a 3rd party package, on linux. 

After I installed Xvfb (x virtual frame buffer) server rpm, the error went
away. (http://www.xfree86.org/4.0.1/Xvfb.1.html) I think there was a clue
in the error log.

If you're on Fedora, you can just do yum install xorg-x11-Xvfb or do
yum search Xvfb. I don't think I had to "run" it actually. 

Don't know if it will help you, but just in case.

Re: java.lang.VerifyError Wrong return type in function

[Ole Chr Langfjæran]

Found the problem/solution. The error occurs because Tomcat uses java
5.0 while the servlet has been compiled with java 1.4. Compiling the
servlet with 5.0 resulted in a much nicer log!

Where are input output files located?

[Per Arve]

Newbie running Tomcat 5.0.28 on OSX.

Hi, I am starting tomcat by running a script that runs the  
catalina.sh script. I have experienced that files that my jsp-app  
produces end up at different places depending on how tomcat is  
started. Possibly I could understand this if I knew a little about  
unix-commandfiles, but right now I'm lost. Running as a demon should  
be more robust, but I worry about where the files might end up then.  
Can I use the recipee for unix system on osx, ie.


cd $CATALINA_HOME
./bin/jsvc -Djava.endorsed.dirs=./common/endorsed -cp ./bin/ 
bootstrap.jar \

-outfile ./logs/catalina.out -errfile ./logs/catalina.err \
org.apache.catalina.startup.Bootstrap

to start tomcat as demon?

Re: PreparedStatement w/ Connection Pooling

[Khawaja Shams]

I am guessing the main attribute to change is the following:
  poolPreparedStatements="true"

Suppose that this is set to true, how do I access these pooled statement? My
setup is exactly as you described, so this modification seems minor, but I
would appreciate guidance on how to get a hold of these pooled prepared
statement.  Thanks for your help.

Re: Image Scaling Code

[Dakota Jack]

You need to set a java command option so that your code won't search for a
display.  Apparently you are using this with a server that has no monitor?
I forget the option but look them up under the java command and it will be
obviously.  It ends in "less" as I recall.

Good luck to you.

Thanks Everyone,
 
 Your many responses were correct.  I'm on my way.  Closer anyway, I get a 
different error now, but I think I can track it down.  I'll let you know if I 
need any more help.

This looks like a variation of the 'headless' problem.  (Are you
running X11 on the server?)

Try running Tomcat with:
   CATALINA_OPTS="-Djava.awt.headless=true"

Re: rebuild-jar-repository error

[Bob Hartung]

Ghislain,
  I downloaded the sun tarball, the tomcat5 tarball and had both 
installed in less than 5 minutes.  Tomcat5 tested fine with $JAVA_HOME 
defined in /etc/profile.
 I was the able to install the MIRC storage service in an additional 5 
minutes.


 Now, I may have upgrade problems but after days of fruitless attemtps 
at making this work with the rpms from jpackage and home build rpms 
following expert advice, I am just glad to see that the case repository 
service actually works and I can start to learn it.  As this is a test 
setup, i will continue try and get it going on a different machine with 
rpms but at a much slower pace.

It's Tomcat's admin webapp (which is struts-based).  It looks like it's 
broken in the 5.0 branch.

No, it's actually because it's including a welcome-page.  TC 5.5.x handles

Tomcat5 and supporting files

[Bob Hartung]

Hi all,
  I need direction to an information repository that will explain what 
I need to do to get java-1.5.0 and tomcat5 installed and running and 
then allow installation of MIRC software, that requires tomcat5 on 
jvm-1.5.0 for the newer version.


  I have spent nearly two weeks of off ours (read evenings and 
weekends) .  I still have a huge number of issues.  In the latest 
attempt, I have done the following:


1.  reinstalled FC4 as a clean install wiping all HD.
2.  updated FC4 with a simple yum update
3.  downloaded java-1.5.0-sun and rebuilt the rpms per Peter Horwarths 
articles.

4.  installed the java-1.5.0 rpms with yum installlocal *.rpm while in
/home/localuser/rpmbuild/RPMS/i586/...
5.  Installed tomcat5 with yum --enablerepo=jpackage* install tomcat5
6.  I was then able to go to http://localhost:8080 and get the tomcat page
7.  I then installed the MIRC software - which seemed to go okay,
but refused connections then I tried to go to http://localhost:8080.

I am not a Java programmer and am new to Tomcat.  Is there a concise 
information sheet on how to set this up with rpms, especially with yum 
or should I just shuck it and go with the tar.gz, which I have 
successfully used before but which are harder to upgrade?  I am about to 
wipe this computer and reinstall again so i have a clean starting field, 
but do not wish to invest any more time in dead-end goose chases.


Thanks

Bob

RE: PreparedStatement w/ Connection Pooling

[Marc Richards]

If you're already using pooling then I imagine you
already have a resource defined for the pool in either
server.xml or in the context xml file.  To pool
prepared statements, which is desireable, you should
configure it to look something like this in Tomcat
5.5:




Note that in this example I'm using an IBM iSeries DB2
database driver, not my sql, but the rest of the
config should be close to the same with the exception
that on a production machine you'll want to have your
initialSize, maxIdle and minIdle set much higher
depending on the number of concurrent connections that
you expect to make.  
Also note the url parameter - DB2's jdbc driver and
database support dynamic package support with prepared
statements, which can sometimes offer huge sql
performance gains due to the system's ability to offer
better optimization for prepared statements and cache
the optimization so that the SQL optimizer need not be
initialized for every subsequent statement.  I don't
know if my sql supports this or not, but you would
definitely want to look into it.
Lastly, note that this configuration is only
applicable to Tomcat 5.5 and possibly later versions. 
Tomcat 5.0 and previous require a different syntax,
using a more structured xml format, which can be
reviewed here: 
http://tomcat.apache.org/tomcat-5.0-doc/jndi-datasource-examples-howto.html
The best possible database configuration is as
described above - using connection pooling with
prepared statements and SQL package support - in cases
where stored procedures are more difficult to manage. 
Stored procedures work great when you have several
queries that are required to run in sequence (and
usually offer better performance in such cases), but
may end up a tad overkill from a maintenance
perspective when you have a few isolated queries here
and there.

server.xml
 

The problem is this, I have a jsp page with will result in about 14KB worth
of HTML..

with compression off .. this page doesnt not load, i keep getting a could
not load page .. if i create a html file representing the output of the jsp
... this is what i get when using wget ..

For the JSP file it keeps looping ..

I have set no-cache for the jsp page and the page buffer is 32 kb ...

Any ideas on what could be going wrong .. like i said .. it works fine with

I can't tell which webapp it is, but one of the struts-config files is broken.

It looks like someone has used the the  tag in a
Struts 1.0 config file.  Look for a struts-config file (usually named
struts-config.xml) that has this at the top:

http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd";>

and also has a  tag in it.  Most likely, you're
really using a newer version of Struts, so fix the DOCTYPE and the
error should go away. :)

Re: Tomcat start but many errors in catalina.out

[Khawaja Shams]

This may not be very helpful, but it is definitely something regarding a
missing parameter on your struts configuration. double check your
struts-config.xml for errors.

Re: Tomcat 5.5 system requirements

[Khawaja Shams]

I believe all you should need is java 5.0 and the ability to listen on a few
ports >1024.  perhaps, admin rights to install the software if you are using
the installer.  I am sure others can give you a much more concrete list, but
this is a start.

You've got to be kidding.  Copy by hand!?  Why?  Just build the jar
file to some predefined location, and have the build process for each app
copy it from there.  There's no need to copy it by hand, have ant, or whatever
you're using to build, do it for you.
That seems much simpler than playing with custom class loaders, or
startup classpath dependencies, or loose class files.
e.g. say you've got 4 different api's.  When you build those, a jar file
gets created in (e.g.) /myjars:
/myjars/api1.jar
/myjars/api2.jar
/myjars/api3.jar
/myjars/api4.jar

Let's say app1 uses api's 1, 3 and 4, so it has something like this 
somewhere in its build.xml:  (assuming you're using ant)



and app2 uses 2 and 4, so it instead has:


etc...

of course, if you don't want a global location for the api jar files,
you can always use a relative path.  This is what I do in my app.  I've
got a directory structure that looks like this:
   mycode/
  myapi/
build.xml   (builds the java files and creates myapi.jar)
build/myapi.jar
  myapp/
build.xml   (copies ../myapi/build/myapi.jar to build/WEB-INF/lib e.g.:

build/WEB-INF/lib/myapi.jar

Re: how to change the APR protocol for may use keytool self-signed certificate

[Dhaval Patel]

Hi,

  I hope you have read my post a while ago (in which I explained about 
configuring SSL with APR in
Tomcat 5.5.12). If you haven't,
http://www.mail-archive.com/users%40tomcat.apache.org/msg02500.html

  If you read that post fully, you will understand basics of SSL with Tomcat. 
If you want to learn
more about it, just browse the mail-archive for Nov 2005 and Dec 2005 threads. 
There was a nice
discussion on SSL with APR on Tomcat 5.5.12. One update. It does not work for 
Verisign/Thwate
certificates (search the thread and you will find solution) but it does work 
for self-signed
certificate.

  Based upon my knowledge, APR does not work while using keytool. keytool is 
part of JSSE and APR
is designed to run with OpenSSL. OpenSSL is more standard in industry 
environment. (Tomcat gurus
please correct this if I am wrong).

  One more thing. If you search the mail-archives, before posting message, it 
would be good for
you. You will find solution by yourself which is nice. And many questions are 
answered in this
forum. You just need time and patience to find right thing.

Regards,
D

RE: PreparedStatement w/ Connection Pooling

[George Sexton]

Generally speaking, if you were using most SQL databases the approach would
be to use a stored procedure. The stored procedure compilation saves the
various query plans as part of the data of the stored procedure. I doubt
MySQL does it, but you could ask on their development list.

PreparedStatement w/ Connection Pooling

[Khawaja Shams]

Hello all,
I am working on a web application that will manage
assignments/students/classes for the teachers at a school.  Most of my pages
in the application need to access our mysql database very frequently.  For
this and for other security reason, I would like to use preparedStatements.
However, from what I understand, preparedStatement are prepared on top of a
connection.  If I am using connection pooling, this seems to be useless for
performance as I would be preparing a statement each time I get a
connection.  Is there any way to get around this? Is there such thing as a
preparedStatement pool? Would you recommend implementing this on my own?
Thanks for your time and help.

connection pooling mysql (Pool Exhausted exception)

[Khawaja Shams]

Hello,
   I am consistently getting exceptions about my connection pool being
exhausted in my application.  I am curious where I can configure the number
of connections tomcat should maintain in the connection pool.  Lastly, am I
right in assuming that the only thing I need to do in order to return a
connection to the pool is to return to close the connection? Do I have to do
anything about the statements I have created using that connection? Thanks
in advance.  for your help.

The session is tracked by the servlet container, and

D'oh!  Now *THAT* rings a bell :)

Here is my code:


package com.everybuddystree;

import java.awt.image.*;
import java.io.*;
import javax.imageio.*;

public class ImageScaler {

public ImageScaler() {
}

public boolean scaleImageByWidth(String fileName, int newWidth) {

  int height = workingBufferedImage.getHeight();
  Image workingImage = workingBufferedImage;
  workingImage = (Image)workingImage.getScaledInstance(newWidth,-1,1);
  BufferedImage finalImage = (BufferedImage)workingImage;
  ImageIO.write(finalImage, "jpg", originalImage);

  return true;

 } catch (IOException ex){

  return false;

 }

}

}

When I run the pass an image to the class using a jsp I get the
following errors from Tomcat:

Re: Problems Using Context Loader

[Michel Costa]

The major problem is not about putting hibernate in the context's lib folder, 
but as you may know, hibernate does some mapping stuff, which means it reads a 
bunch of .hbm.xml files into memory, connects and validate these mappings 
everytime the context gets reloaded, and depending on how much mappings you 
use, a bigger problem you have, about the loading time... It takes about 30 
seconds for each reload and a maximum of 4 reloads.

The difficult part of it is to make my custom ClassLoader access the webapp's 
classloader... because it must be placed in the server folder and because of 
this, it is not in the webapp's classloader hiearchy.
Mine implementation speed is a little slow, i am just trying to load the 
classes primarly, with no errors, and then is time to think about reloading... 
I think it would be much easier if I could monitorate these files directly from 
the WebApp's classloader, but this means modify tomcat's distribution.

This is all I have done so far:

public class DeployerClassLoader extends WebappClassLoader {
private static Hashtable classes = new Hashtable();
private String rootFolder;

public DeployerClassLoader(ClassLoader parent) {
super(parent);
init();
showTree(this, "");
}

private String showTree(ClassLoader cls, String pre) {
if (cls.getParent() != null) {
pre = showTree(cls.getParent(), pre);
}
System.out.println(pre + " - " + cls.getClass().toString());
return pre + " ";
}

private void init() {
System.out.println("!!!calling init!!!");
rootFolder = "/opt/tomcat/webapps/AppRoot/WEB-INF/classes/";
}

private byte[] findInPath(String name) {
String path = name.replaceAll("\\.", "/");
File fClass = new File(rootFolder + path + ".class");
if (fClass.exists()) {
try {
FileInputStream fStream = new 
FileInputStream(fClass);
byte[] all = new byte[(int) fClass.length()];
fStream.read(all);
return all;
} catch (FileNotFoundException e) {
return null;
} catch (IOException e) {
return null;
}
}
return null;
}

return classes.get(name);
}
return super.findLoadedClass0(name);
}

synchronized (this) {
Class c = defineClass(name, data, 0, data.length);
classes.put(name, c);
return c;
}
}
throw new ClassNotFoundException(name);
}

public Class findClass(String name) throws ClassNotFoundException {

if (!started) throw new ClassNotFoundException(name);

// (1) Permission to define this class when using a SecurityManager
if (securityManager != null) {
int i = name.lastIndexOf('.');
if (i >= 0) {
try {
securityManager.checkPackageDefinition(name.substring(0,i));
} catch (Exception se) {

Re: Image Scaling Code

You need to have:

-Djava.awt.headless=true

in your java start up args, this will prevent it from trying to talk to an X 
server.  Obviously some image related stuff has to talk to an X server, but 
just ImageIO stuff is fine.

This looks like a variation of the 'headless' problem.  (Are you
running X11 on the server?)

Try running Tomcat with:
   CATALINA_OPTS="-Djava.awt.headless=true"

Re: Image Scaling Code

[Frank W. Zammetti]

I don't quite see how this is Tomcat-related, but...

Your code can't connect to your X server, which is necessary for many 
Java graphics-related functions to work on a *nix system.  I dealt with 
this at one point when getting DataVision working on Linux, and I recall 
the solution being something to do with an environment variable, but the 
exact answer eludes me.


Actually, it looks like you *have* defined the environment variable 
(DISPLAY in the stack trace rings a bell).  Is X running?  I believe it 
has to be for this to work.

Thanks. I didn't use your implementation for the reason noted in the 
comment I attached to the issue, but you pointed me in the right 
direction.

I solved the problem by also implementing a web app class loader and 
attached the source to the above issue. 

Thanks again :-)

You shouldn't do that.  Read the servlet spec, and put the servlet
classes where they belong:

webapps//WEB-INF/classes

ROOT is for the default application.

Unnecessary, non-portable, and unreliable, as you have now discovered.
You should be using something like this:

Thread.currentThread().getContextClassLoader().getResource()

By "No, that is not a Tomcat problem...", I believe you're saying that
there's no problem related to startup etc.

Ack. So you're placing hibernate in the Context's WEB-INF/lib folder ?
I haven't used Hibernate yet, but will do so to understand this issue.

Is this what you want ?
a) Hibernate etc are loaded just once.
b) Your apps' classes are monitored and when ever they change, a fresh
classloader is instantiated.
c) At this time, Hibernate etc are not to be reloaded.
d) Hibernate and Struts and anyone else should continue to to have
access to the latest classes.

I see a problem with Hibernate having a reference to the older classes
(perhaps in objects that are cached, etc. I don't know for sure, I'm
just speculating here). This would be an interesting problem to solve.

If you don't get this right, then let me know, I'd like to help. I'm
interesting in solving this classloader requirement as well - it'll be
a good exercise for the mind :)

Best of luck :)

Correct. It was just something I put together late at night. I'm
considering adding stuff like monitoring for changes in the classes
mentioned in these paths, etc. I'll look into this. Let me know if
you'd like to see some feature.

The simplist way is to rename your app to ROOT. If read about creating a

Hm, sorry, my fault. I never think about small tomcat webapps. I've got 
experience only with big clustered applications, so I always think about this 
trio:
- tomcat

Re: Tomcat integegrated with Apache

[Marco Rossi]

In the pastI used a lot of proxy architectures and I lliked it. 
Despite this the statefull firewall mania brings to my atttention lots of 
people that use iptables for nearly all type of redirection. 

It's fast, it works well in linux you can change on the fly, my only objections 
are it's not an application aware solution and tracking back sources ip is not 
as easy as it seems (you can play with loggin options but after you have to 
parse iptables log files)

One view: Why go through another user-level process when you can simply
redirect the socket connections via iptables for fewer CPU cycles and
less RAM?

Another view: squid may be faster at serving static content, so
interposing it could be useful if you suspect that is a bottleneck.
Recent Tomcats are faster than older Tomcats at serving static content.

My view: It depends on your mix of content and your webapp.  In general,
it's not possible to know which is more efficient *in your environment*
without benchmarking it.

You appear to be attempting to import (last step) the certificate

create self signed cert to import, if you dont need users to trust your

If I can avoid using Apache, then I run tomcat on a non-privileged port and
use IPTables to re-direct from port 80 to the non-privileged port.

Changing default web apps

[Marco Rossi]

Hi all,

I'm trying to deploy a single web app to serve a whole web site on port 80. I'm 
able (finally:-) to use jsv to redirect port 80 to 8080, but I'm wish to 
chanche the default application that listen on port 8080. 

I noticed that the files to be server are coming from webapps/ROOT, how can I 
set as default webappas/MyApp/index.jsp in tomcat 5.5.12 ?

Thanks

Re: tomcat and javac (UNCLASSIFIED)

[Zorro3692]

Hi Chuck,
 
   Thanks for your reply.
Can you please help me with the following question I posted earlier.
 
 
 
Hi,
 
I recently downloaded and  installed Tomcat 5.5.12. I read the 
documentation on class loading. However, my  webapp does not work on Tomcat 
5.5.12 
when I put my servlet classes in  common\classes.
 
My webapp consists of .properties files, .class files ( servlets) and  jsp's.
 
In the last version of Tomcat 3.0X that I used, the class files would go  
into webapps\ROOT\WEB-INF\classes.
 
The properties files would be in ROOT\WEB-INF and all the jsp files in  
webapps\ROOT.
My servlet class files would contain the path to the properties files  in 
ROOT\WEB-INF.
 
Everything worked just fine.
 
Now it's totally confusing. I have recompiled my servlets to reflect the  new 
path for the properties files in webapps\ROOT\WEB-INF of the Tomcat 5.5.12  
installation. But nothing works. The error I get is that the servlet resources  
are not available.
 
I am a student and this is my former homework project.
 
Any help would be highly appreciated.
 
Regards,
 
Jimmy Wadia

There  are three jasper-*.jar files in common/lib.  The actual Java
compiler  appears to be in jasper-compiler-jdt.jar; I have not attempted
to use it  outside of Tomcat in any way.

running tomcat 5.0 as windows service - how do I get it to use the security manager and catalina.policy?

[Stracchino, Peri]

hi guys
 
I am trying to get tomcat 5.0 to use the security manager and
catalina.policy when running as a windows service. This works fine when
I run it from startup.bat using the normal "set CMD_LINE_ARGS=
-security" method. However I cant find any documentation - either on the
tomcat site or on the web - on how to tell it to use the security
manager when starting it up as a windows service.
 
So far I'v experimented with the following, using the  'Configure Tomcat
UI' which I assume is the correct place to start when running as a
service.

*   If I add "-security" after 'start' in the arguments field on the
startup tab, I get a message telling me the service started and then
stopped.
*   If I try adding "-security" to the java options tab on the
'Configure Tomcat UI, I get a message telling me simply that tomcat will
not start.
*   If I try adding the line "-Djava.security.manager
-Djava.security.policy=C:\Program Files\Apache Software
Foundation\Tomcat 5.0\conf\catalina.policy" to the java options tab then
tomcat starts, but a bit of experimentation with the permissions in
catalina.policy suggests that it isnt actually using it - even if I
remove essential permissions the application can still access the
relevant files.

Can anyone tell me the correct procedure for ensuring the security
manager is used and catalina.policy referred to when running as a
service in 5.0? It is running on both  XP and Windows 2000 platforms
 
Cheers

No limit, other than the max number of threads configured for the
connector.  See:

for details.

Sessions don't access servlets, threads do.  Multiple threads may be
processing requests under the same session simultaneously, so
synchronization is required where appropriate.

Does Tomcat now have caching of LDAP authentication (i.e. for basic

Does Tomcat allow a single web app (and URL therein) to be authenticated 
against multiple LDAPs (i.e. where part of the user community is defined 
by each)?


Is there a SiteMinder plug-in for Tomcat?

These sorts of things also currently drive folk to use Apache currently.

RE: Tomcat integegrated with Apache

[Gary Blomquist]

Thanks.

As I mentioned we are considering buying a hardware load balancer.  I
just wondered what problems I might encounter if we did choose to load
balance with Apache.  Our volume is relatively low.  We want the load
balancer so we can have hitless upgrades.

Our app. uses frames.  Could that cause a problem with load balancing
and non-sticky sessions?

RE: Tomcat integegrated with Apache

I can give a reason. Its called Connector de-jour. The "preferred"
connector, changes every 6 months and they're bloody impossible to configure
and keep straight. Building a connector is impossible unless you are a
REALLY highly skill UNIX sysadmin.

My advice is this:

Set up your machine running tomcat. Download Jmeter, and test it. I'm
betting that tomcat can service enough data to more than adequately meet
your needs. In my App, running really complex servlets with database
interaction, I was hitting 6Mb/second throughput. Pages that didn't involve
the database, just complex servlet logic were coming out at something like
24Mb/s. This was a commodity grade P4.

Re: Problems Using Context Loader

[Michel Costa]

No, that is not a Tomcat problem... it's a specific application problem... I 
saw some people complaining about the same things in applications similar to 
mine.

The big whole problem with my application is the framework usage: Hibernate and 
Struts...
My guess is that hibernate is not finalizing normally (i done some tests 
restarting the context using only struts and garbage collecting and checking 
the amount of free memory)... cause when I restart the context about 4 times 
using hibernate and struts there is no more free memory neither memory to 
allocate. It ends with a Heap space error.

Every time a new class is compiled during development the context must be 
restarted to update the class reference, so now we have a problem.

My way out is to make a classloader to monitor these classes in classes folder 
and auto-update the reference...
Wish me luck ;-)

I will take a look at your idea... but seems you are not trying to reload the 
classes references.

You place your class at CATALINA_HOME/server/classes. See the bug

RE: Using Tomcat 5.5 as a standalone web server

Security is not a key issue for us, over and beyond observing good
general site security principles. Given that there is far from a
consensus opinion on this question, I am going to stick with Apache
2.0.46 / Tomcat 5.5.7 as an integrated solution, but do some testing on
Tomcat standalone as well to see how it performs.  I would love to go to
pure Tomcat, but I can't risk it on this particular site ... For now! I
have noted the caching solutions people have suggested - they may form
part of a future non-Apache solution if traffic continues to rise.

There is quite an easy sollution. 

Run squid as you main webserver and as a web accelator in front of your
tomcat. From the squid config you can decide what your want cached and
what now. I don't understand why this is not done more often since its
A) a very easy sollution
B) does not loose any of the funtionality tomcat can offer you
C) allow to fine grain the load of tomcat completely

Only downsite, the squid cache in core memory gives of course the best
performance so as much memory as possible will help. On the other hand.
The HTML of much sites fits easily in 500MB core memory.

mention above, on Tomcat alone? I want to avoid the web server
integration if Tomcat is up to it, but I would love to hear if anyone
else has been successful with Tomcat standalone before I do?
 
Many thanks!
 
Adam

RE: how to suppor 30000 concurrent users

[Peter Crowther]

Depends very largely on your webapp.  How efficient is it?  How many
operations per minute is each user making?  Does it require session
state, or can you get away without it?  Can it be clustered?

I strongly suspect that you'll make much more of a difference by careful
construction of your application than you will with Tomcat's overhead.
That said, http://www.theserverside.com/news/thread.tss?thread_id=38377
may be relevant - no doubt others will come up with better links!

RE: Problem with servlets from upgrade

[Francesca Jovanovic]

Thanks so much for replying.
My URL's are mapped, below is an example. 
I had this working on my old PC for the past 2 years with no problems then I 
got a new pc and installed the latest tomcat, set the environment vars and 
copied everything over to the relevant folders but things are going horribly 
wrong.
I'll read through that doc and see if anything I've missed comes to light.

I am not sure I follow you here. There is a session object you can get
from the request that makes it possible tostore data through several
request in the same session. request.getSession().setAttribute("akey",
anObject) to set session attributes.
request.getSession().getAttribute("akey") to get attributes. If you have
users that log in and out you probably should set some user identifying
info in the session and a filter to makes sure that the user is logged
in for certain requests.

Re: problem of setting up ssl in tomcat 5.5.9

[Siddhartha Mehta]

I am not sure if anyone has replied to you on this..
   
  At least from what I understand, the error below means is that the 
certificate file server.pem is not found as specified in the server.xml 
(configuration file) entry.
   
  You will find the server.xml file in the conf folder (under tomcat installed 
directory) and search for server.pem. Then verify if the path that is specified 
in server.xml to server.pem is valid or not. See if it helps.

Tomcat error???

[Junem Albert REpollo]

  hi.
   
  i have this _javascript which writes a file into a specified directory. it 
works well outside the tomcat 5.x server. (Put the code in a htmll file, view 
it with IE then the code works). however, if i transfer the code to the tomcat 
server, i get an error "server doesnt support automation of object" what error 
is this??? how can i fix it??? here's my code:
   
  
function CreateFile(path,text){
  var fso;
  var tf;
  fso = new ActiveXObject(Scripting.FileSystemObject);
  tf = fso.CreateTextFile(path,true)
  tf.WriteLine("Scheundt");
  }
  
   
  hope i can find some solution...
   
  thanks
   
  salamat

Hi
i have some doubt in tomcat deployment, can some one clear that

I have one web appliation that i deployed in the tomcat and running fine. it 
uses login, and all the valid users will login and use the site. it contains 10 
servlets each will do one kind of job based on the user request.

No my question is how many user can login and open session in tomcat at a given 
point of time. is there any restriction for that? if yes can we configure that 
and where?. second one is at a given point of time how many sessions can access 
one servlet. I belive if a user asks servlet to process request it will create 
a thread for that reuest. so how many session can conact a servlet at a time to 
process the same request.

Kindly help me get clear in this.

thanks and regs,
bangs
