Error Message Explanation

[Hari Venkatesan]

Any idea what this error means?
 
1) org.apache.jk.server.JkCoyoteHandler  - Error in action code 
java.net.SocketException: Connection reset by peer: socket write
error
 
2) WARN - Server has closed connection
470508266 [Thread-6] WARN org.apache.jk.common.ChannelSocket  -
Server has closed connection
 
I am using Connection Pools and my timeout is set to 15 seconds. Is the
above error because the server is closing connections upon timeout?

RE: Driver for connecting to a AS/400

[Hari Venkatesan]

You have to JT400.jar file to make DB connections to the 400. The Driver
Class name you can use is com.ibm.as400.access.AS400JDBCDriver. Remember
that this driver is type 4 driver. 

You need not make any changes to the as400. You can connect to the
database with your username and password.

What is the driver that i have to use to connect to a AS400, for make
consults to a database DB2 that is in the AS400.
from a Tomcat 4.1 configured for default, running in a Mandrake linux
8.2.
I have the jt400.jar in $CATALINA_HOME=/common/lib/jt400.jar, some guys
toll us that this is the drivers that i have to use to make a
connection.
and what i have to write in the Class.forname, if i have the correct
driver, I have to make any changes in the as400 or with the username and
password its just fine.


Thanks a lot.

RE: Tomcat 4.1 ignoring -Xmx params

[Hari Venkatesan]

How did you find out it is ignoring -Xmx parameter. Initially when you
start up tomcat, it would allocate only the minimum heap that you set in
-Xms.

Hello all.

I'm new to the entire concept of Tomcat and I have a question which I
have not found a clear explanation for.

Does Tomcat have to be installed on the webserver?  In other words, can
I not just install the redirect filter (and not Tomcat, per se) on the
webserver and have it connect (using ajpv13) to a back-end Tomcat
server?  I only want to install the redirect filter on the webserver.
Does a working JVM need to be in place for the filter to work properly?

Howdy,
A few things.  First, you original question:

>Have anybody got to see GC output in catalina.out log? ?

Yes.  Every single time I've followed the above instructions, I see
verbose gc in my catalina.out file.  If I use JDK 1.4 with the
loggc: option, it goes to that file.  If I omit that option and
enable swallowOutput for the Logger in server.xml, the verbose gc
information goes there.  I've had no problems with this at all.  In fact
I've tested this functionality on every point release from 4.0.1 to now.

All my attempts are on linux and Solaris platforms.  I wouldn't run
anything serious on a Windows box any time soon.  It may be that some of
the above doesn't work on windows, or when running tomcat on windows as
a service, which you mentioned is your deployment setup.

>There are a lot of people out

Assuming you mean deployed instead of implemented, I agree.  But I think
the above number is far exceeded by the number of people who believe
there are magic garbage collection tuning settings that'll make all the
GC problems go away.

>Off late there have been many  queries about memory management and the

Not just of late.  For a long long time now.  And not just on the tomcat
lists either.  It's a difficult topic that many people struggle with.

>now, still without any right answers even after searching the archives.

See above: the right answer is one only you can find for your own
particular app.  There's no magic GC combination that'll perfectly tune
your JVM.  What worked for others may not work for you.

>Different JVM's do memory management in its own way and that is even
>more confusing.

It may be confusing.  But in fact, as someone who's written a JVM,
memory management and efficient collection are distinguishing factors.
It's a key value added if you can do it well: hence JRockit and others.

>You start tomcat with -verbose:gc, you can see GC kicks in even as it

Yup.  All the time.  This is normal and expected.  They're usually
incremental or young generation GCs.

>starts. From what I learnt from java.sun.com, a full GC kicks in only
>after it reaches its max heap. But you can see Full GC's in the verbose

No, that's not true at all.  A full GC may kick in long before max heap
is allocated.  In fact, the JVM will usually try to never even get
close.  By default the minimum percentage of the heap it'll try to keep
free is 40%.  You can tune this with XX:MaxHeapFreeRatio= and 
-XX:MinHeapFreeRation=

>By the way I have gone through the entire archive about this topic and
>none of them give a final answer.

Again, what's a final answer?  What sort of answer would you have liked
to see that wasn't in the archives?  It may be that the only "final"
answer is:
- Come up with performance goals
- Come up with performance tests
- Run tests, record results
- If goals are met, stop, else
- Modify one GC parameter
- Run tests, records results
- Repeat until goals are met.

RE: Memory Mgmt Tomcat

[Hari Venkatesan]

When you start tomcat4.1.12 on Win2k as a service with verbose:gc, i do
not see the GC output in Catalina.out. I tried and tried and finally
settled down to start tomcat from command line for testing purpose. 

"To collect data on how long garbage collection is taking add the
-verbose:gc argument to your CATALINA_OPTS environment variable when
starting Tomcat.When verbose gc is enabled your
$CATALINA_BASE/logs/catalina.out log file will include data for every
garbage collection including how long it took."

Have anybody got to see GC output in catalina.out log? ?

Hi!
   Well I am also getting the same out of memory errors, FI: I am using
Oracle database.
   I found some info that talks about setting time-out for DB Con
Poolng.
   Will start with this info and see how it helps. Pasting the info
below
for any further analysis and comments by the grp:

"Tomcat runs within a JVM. The JVM periodically performs garbage
collection
(GC) to remove java objects which are no longer being used. When the JVM
performs GC execution of code within Tomcat freezes. If the maximum time
configured for establishment of a dB connection is less than the amount
of
time garbage collection took you can get a db conneciton failure. To
collect
data on how long garbage collection is taking add the -verbose:gc
argument
to your CATALINA_OPTS environment variable when starting Tomcat.When
verbose
gc is enabled your $CATALINA_BASE/logs/catalina.out log file will
include
data for every garbage collection including how long it took.When your
JVM
is tuned correctly 99% of the time a GC will take less than one second.
The
remainder will only take a few seconds. Rarely, if ever should a GC take
more than 10 seconds.Make sure that the db connection timeout is set to
10-15 seconds. For the DBCP you set this using the parameter maxWait."

Thanks,

I don't think the question is ridiculous. There are a lot of people out

like this.

Off late there have been many  queries about memory management and the

Personally, I have been researching the same problem for almost a week

Different JVM's do memory management in its own way and that is even

You start tomcat with -verbose:gc, you can see GC kicks in even as it
starts. From what I learnt from java.sun.com, a full GC kicks in only
after it reaches its max heap. But you can see Full GC's in the verbose
output even before the JVM reaching its max heap.

This makes you believe that something is wrong somewhere and that is

By the way I have gone through the entire archive about this topic and

RE: Tomcat Out of memory

Nate  

Take a look at the following site. It gives you a feeler of how to do
it. Once you run the batch file, it updates the Win2000 registry entries
for you. From there you can play with it. 

http://www.mattkelli.com/tech/tomcat/ntservice.htm

When you follow the instructions, and run the batch file, you would see
something like this in windows registry under 
SYSTEM/CurrentControlSet/Services/Apache-Catalina/Parameters

JVM Option Number 

Check what has been set up under that.

RE: Memory Allocation

[Hari Venkatesan]

Shapira,

Thanks for your suggestion. When you startup Tomcat with -Xms10m and
-Xmx10m it does a lot of Full GC before it can bring up and finally
settles down to use 7.2megs using a debugger.

Without a debugger tomcat still comes up after doing a lot of Full GC's.

I have just one application in my context in my server.xml and have just
2 load-on-startup servlets which is not big (one gets the roles from
ldap server which loads a maximum of 5 roles  and the other starts up
log4j. 

No Realms have been defined. I use Win2k, Tomcat 4.1.12 and JDK
1.3.1_06. 

Without Using jprobe or OptimizeIt is there a way to check how much
memory has been used.

Howdy,
Whoa there ;)  Be very careful about some things:

- The amount of memory tomcat takes on startup is variable.  This
changes with tomcat version, OS version, JDK version, configured webapps
and their listeners / filters / load-on-startup servlets, any
Loggers/Valves/Realms configured for tomcat in server.xml, etc.  As you
can see this is many variables.

- Using a debugger such as JProbe or OptimizeIt may inflate the memory
usage of a system by a factor of 10 or more.

- What the other guy said about the default heap set at 64MB -- the
default heap MAXIMUM is set as 64MB.  The default minimum is very small,
again depending on JDK version and flags used.  

For an illustration, try the following:
- Set -Xmx10m in your JAVA_OPTS to allow only 10MB on the heap.

RE: Tomcat running as an win 2000 service

Take a look at the following site. It gives you a feeler of how to do it. Once you run 
the batch file, it updates the Win2000 registry entries for you. From there you can 
play with it.

I have a -Xms set to 128m and -Xmx set to 256. But does tomcat itself

Its probably set in the jvm - the default heap size set is for 64 meg.
This can be changed using the -Xmx parmeters in the initial call to the
jvm. We set the max heap size for our tomcat to 128M using:
  "-Xmx128M"

Tomcat when starting uses 60M memory in heap. Why is that it is using so
much memory in heap. I found this by running jprobe memory debugger. I
have just one application in the context of server.xml file and don't
think the entire application gets loaded into memory. After doing a full

[Hari Venkatesan]

Tomcat when starting uses 60M memory in heap. Why is that it is using so

have just one application in the context of server.xml file and don't

RE: Startup parameters

[Hari Venkatesan]

Setting the parameters in Catalina.bat would not work if you run Tomcat
as a service since you service is calling tomcat.exe directly and not
startup.bat or Catalina.bat. 

But to test out before you start the service you can put the values in
CATALINA_OPTS = -Xms128m -Xmx258 etc and run Catalina.bat. You can also
set the values as Environment Variables and forget about changing it in
Catalina.bat

To Run it as service and with the parameters follow the link

Hope this helps

OK, one quick question that I'm sure anybody here but me can answer.

I am running Tomcat as a service on windows 2000 server.  I want to set
some
JVM parameters when tomcat starts (things like -server, -Xmx, -Xms,
etc).
Where would I go about making these changes?  I've looked through the
catalina.bat file, but is this even executed when tomcat is run as a
service?  according to the services applet in the control panel, the
service
runs tomcat.exe.  Does this in turn call the startup script? Or do I
need to
pass the parameters using -jvm_option to tomcat.exe?  As an aside, is
there
anything that can be done to optimize tomcat for execution on a
multi-processor system?

But the only catch running tomcat as service with the start up

[Off-Topic] Memory ALlocation in Win2K

[Hari Venkatesan]

When I start the JVM with -Xms512m, where does the memory gets allocated
from. Is it from System main memory or from the virtual Memory. 
The reason I ask this is when I look at Windows Task manager I could see
a bump in the MEM Usage portion. But the amount of Physical Memory
(Total + Available) does not add up. 
I thought it was allocating from Virtual Memory and hence changed the
physical memory to 64 meg instead of 1024 Meg. Still it does not add up.

 
Can somebody throw some light on this.

Hi again, 
Few tips : 
Use connection pooling, cache data from database if you can, lazyload data from 
database when that is a good idea etc.

Creating connections to DB2 is not the fastest thing around, so I suspect connection 
pooling may take 2 seconds of that time.

Thanks Reynir,

This was exactly I was looking for. Our Jsp's are loading very slow. We are using JDBC

about 7 - 10 seconds for our JSP's to load.

Hi, 

In my understanding it really only affects performance. 

The first request on a jsp always takes longer to execute because at that time it must 
precompile the jsp. 
If you run a precompiler (such as jspc) on the jsp pages before you start up the 
server (or at startup) you will shorten the time of response on the first request of a 
jsp page.

If you are dealing with performance there are many other things that you might want to 
look at. 
I recommend the following page as a good material on this matter:

Maybe so.  Seems pretty straightforward to me.  I'm sure the dev team

Since the dev team is focusing on JK2, and ApacheConfig only works for

I'm not sure they will give it much attention.  Worth a shot, though.

Thanks for the reply john. I got it. But there is one small problem yet to resolve. 
When I use http://something.com/{Webapp}/index.jsp, it comes back with a Basic Server 
Authentication window. I don't have any authentication setup in web.xml file. 

I am using IIS and tomcat and have defined virtualhost in server.xml file. If I access 
the server directly by it name, it is showing me the index page but if try with the 
virtualhost, I get authentication for the server. Any ideas?

Let's put it this way.  If you had to change defaultHost for virtual hosts
to work, then you could never have more than one virtual host, since there
is only one defaultHost.  That's obviously wrong.  Tomcat has the ability to
serve many virtual hosts, not just one. I have several virtual hosts running
on a Sun 420R at the moment, and there's only one defaultHost (and it's set
to localhost).

If you are getting "server not found" then something.com doesn't resolve to
an IP address.  Can you ping something.com?  If not, there's your answer.  

If "something.com" resolved to the IP address where Tomcat was running, and
there was no virtual host defined, then Tomcat would revert to serving the
default context from the default host.  That's what "defaultHost" does.

RE: Virtual Domains with Tomcat 4.1.12 Standalone

[Hari Venkatesan]

If I leave the defaultHost to localhost and have a , when I 
type in the url http://something.com/{webapp}/index.jsp, I get a server not found or 
DNS error. Do I need to define something.com anywhere else in win2000

RE: Virtual Domains with Tomcat 4.1.12 Standalone

[Hari Venkatesan]

I really don't know if changing the defaulthost name is the solution. R u able to 
serve the pages with the configuration you have now without changing the defaulthost 
name or are you getting a DNS error. 

IF you want to serve pages the way you want it, then each of the  entries you 
have in server.xml should have  defined with its own Web.xml file.

Thanks for the response.
( For that matter, thanks for everyone's response so far... )

I want the behavior to be:

http://localhost - loads up the default welcome page, root/index.jsp
http://host0.com - loads up host0's index page
http://host1.com - loads up host1's index page

Is changing the default host part of the solution?

Is this is the change that you are referring to in adding the host tag?

If that is not working, how would I track down what is broken?
(ie, are there log files saying exactly what Tomcat is getting from the request?)

As for adding an alias for localhost, wouldn't that mean that only one host was used?
Ultimately, I'd like host0.com and host1.com to be different "hosts" for Tomcat.

Applying Occam's Razor, I'm pretty sure that something is screwed on my end, but not

Hi,

We are using Tomcat 4.0.4 on Apache.  Right now when we have a request
that
takes longer than 300 seconds(5 minutes), connections are timing out and
we
are getting various errors.  How do we go about increasing this timeout
so
that the request does not timeout.  Unfortunately, The analysis that
runs on
the server is very computational intensive and we have done a lot of
tuning
and most of the times it does run under 5 minutes however depending on
server load and database load we do run over 5 minutes frequently and
error
out.  Ideally, we would like to not have this restriction.  I have
searched
in the archives and Tomcat documentation and have not found anything.

Thanks for your help.

It is not a problem with Tomcat. Your JSP is not getting compiled
correctly into a servlet class.

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

"org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.j
ava:479)"

Your compilation is failing at line 479.


  int count = 0;
  for (int j = 0; j <= 10; j++) {
count = j;
  }


Should this be scriplet or <%

Take a look at your jsp and see if all opening tags and closing tags
exist.

The complete code for two very simple jsp's are below. They both do the
same
thing, display a value. The problem is that (2) gets an internal error
upon
request (error message follows code). (1) works fine.

If I take the for loop out of (2) and set the integer to some value, the
request is processed and the value is displayed correctly. Tomcat does
not
seem to be able to handle a for loop in a scriptlet tag, but is able to
handle it in jsp syntax. This looks like a bug.

Since I am new to Tomcat I thought I would send out the email to see if
there is something I have neglected before submitting a bug report.

Any comments would be appreciated.
Thanks

RE: XML vs JSP Syntax: Looks like a bug

[Hari Venkatesan]

It is not a problem with Tomcat. Your JSP is not getting compiled
correctly into a servlet class. 

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

"org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.j
ava:479)"

Your compilation is failing at line 479.


  int count = 0;
  for (int j = 0; j <= 10; j++) {
count = j;
  }


Should this be scriplet or <%

Take a look at your jsp and see if all opening tags and closing tags
exist.

Subject: JSP: XML vs JSP Syntax: Looks like a bug

The complete code for two very simple jsp's are below. They both do the
same
thing, display a value. The problem is that (2) gets an internal error
upon
request (error message follows code). (1) works fine.

If I take the for loop out of (2) and set the integer to some value, the
request is processed and the value is displayed correctly. Tomcat does
not
seem to be able to handle a for loop in a scriptlet tag, but is able to
handle it in jsp syntax. This looks like a bug.

Since I am new to Tomcat I thought I would send out the email to see if
there is something I have neglected before submitting a bug report.

Any comments would be appreciated.
Thanks
Doug

Hi,

Can somebody point out my mistake for me - I'm starting to bang my
head..

I am trying to get connection pooling working on my AS/400 using the
Commons-DBCP.

I have placed this JAR in /common/lib along with the
JT400.JAR

I have added the context entries to my server.xml file - thus:-



   

   
  
 factory

 
org.apache.commons.dbcp.BasicDataSourceFactory
  

  
 maxActive

 100
  

  
 maxIdle

 3
  

  
 maxWait

 100
  

  
 username

 INTERNET
  

  
 password

 INTERNET
  

  
 driverClassName

 com.ibm.as400.access.AS400JDBCDriver
  

  
 url

 jdbc:as400://10.0.0.1
  
   


I have added this to my WEB-INF web.xml file:-





Resource reference to a factory for java.sql.Connection

instances that may be used for talking to a particular

database that is configured in the server.xml file.





jdbc/shiltonDB





javax.sql.DataSource





Container





And I have this java program to test the connection

import javax.naming.*;
import javax.sql.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletOutputStream;
import java.sql.*;

public class DBCPServlet extends HttpServlet {

   public void doGet(HttpServletRequest req,
 HttpServletResponse res) {

  try {
 ServletOutputStream out = res.getOutputStream();
 out.println("");
 out.println("Using Tomcat Connection Pooling with
DBCP");

 Context ctx = new InitialContext();
 if (ctx == null)
out.println("Something is wrong with Tomcat");

 DataSource ds = (DataSource)
ctx.lookup("java:comp/env/jdbc/shiltonDB");

 if (ds != null) {
Connection conn = ds.getConnection();

if (conn != null) {
   out.println("Got Connection: " + conn.toString() +
"");
   Statement stmt = conn.createStatement();
   String sql = "select * from BSSTYL";
   ResultSet rst = stmt.executeQuery(sql);
   if (rst.next()) {
  out.println("Value of HDCUST on first record:
"+
rst.getString("dbfield1")+ "");
   }
   out.println("This was our little database-access
servlet...");
   conn.close();
}
 }
  } catch (Exception e) {
 e.printStackTrace();
  }
   }

   /**
* if somebody does a http-post, we do an interal dispatch to doGet()
*/
   public void doPost(HttpServletRequest req,
  HttpServletResponse res) {
  doGet(req, res);
   }
}

"ds" is alway null - what am I missing.

Thanks in advance.

LDAP 
and uses the tc SingleSignon. this way that don't get prompted again.

David,

Thanks for the input. We have all the users in LDAP (Active Directory).
But for this specific application, we have roles defined and I need to
retrieve the roles for the user and store them in session bean. For this
I need the userid from windows. Since the user has already been
authenticated against LDAP to signon to windows, I don't want to
authenticate him again by making him enter his id again.

Yes, I am using realm. But actually I don't want the user to type in the
userid. I want to use the same id that he types in when he logs on to

id that the user logs in signing on to the network.

RE: JDBCRealm/Form login get current user ?(hope Craig is listening).

[Hari Venkatesan]

You can create a bean that would store the user in the session after he
is authenticated. 

I hope you have login.jsp which would get the user id and password for
authentication. Once the user is authenticated there would be a
re-direction page (welcome-page in web.xml file).

If you are using struts then this welcome-page can be an action class
that would do a request.getUserPrincipal().getName() from the http
request and store it in a session bean. 

If you are not using Struts then you can call a servlet that would do
the same request.getUserPrincipal().getName() and store it in a session
bean

Hi

I am trying to get tomcat to work but unfortunately I am not getting
far.

Tomcat version is 4.1.12

I have created a directory under webapps called phpserver. This
directory is intended to serve php pages using php as a servlet from an
NT 4.0 machine. I will go onto that once I have the basic config up and
running.

I've written a web.xml file and put it under phpserver\WEB-INF:



  
php
net.php.servlet
  

  
helloworld
HelloWorldExample
  

  
php
*.php
  

  
helloworld
/phpserver
  



I've added the following context to the default server.xml under conf\:


  

I copied the example HelloWorldExample.class across to the directorty
\webapps\phpserver\WEB-INF\classes and restarted tomcat.

I then entered the URL
http://localhost/phpserver/servlet/HelloWorldExample into my browser but
I get a 404 resource not found.

%TOMCAT_HOME%, %JAVA_HOME% and %CATALINA_HOME% are to my knowledge all
correct.

I've tried permutations on a theme for the entries in server.xml and
web.xml (under phpserver\WEB-INF) but I've hit a brick wall here. I have
read many docs (official and not official) and have learnt a lot but
somewhere I'm missing something obvisous.

Can anyone please help me out with this issue??

Thanks

Ben

RE: JNDI results in Cannot Load JDBC Driver Class

[Hari Venkatesan]

Sorry for the late reply

Firstly you have define your datasource for the application in the
context path. I believe this has to be defined for each and every
application. The following is one sample







factory

org.apache.commons.dbcp.BasicDataSourceFactory



username





password





driverClassName

com.ibm.as400.access.AS400JDBCDriver


url

jdbc:as400://RICWC01



maxActive

10



maxIdle
5



maxWait

1




Secondly in your web.xml file'


jdbc/AS400DS
javax.sql.DataSource
Container


In your java program reference the datasource using JNDI Context Factory

private static String dsName="java:comp/env/jdbc/AS400DS";

try
{
ctx = new InitialContext();
ds = (DataSource) ctx.lookup(dsName);

}

This is all I did. I works fine.

Subject: JNDI results in Cannot Load JDBC Driver Class

I have used connection pools with the mySQL database without difficulty.

Now I wish to use connection pools with the
com.ibm.as400.access.AS400JDBCDriver() driver.  I can use this driver
for
direct connections without any problem, but when I try to use it in a
connection pool I get the error Cannot load JDBC driver class
'com.ibm.as400.access.AS400JDBCDriver()'.

I have the jt400.jar file in the tomcat CATALINA_HOME/common/lib
directory,
just like I do with my mySQL jar.  Again, I know it is accessible by
Tomcat, since a direct call from a servlet (non-connection pool) works
just
fine with no errors.

Any suggestions on what may cause this exception and the remedies I
should
look into?

Here's some other details.

My test servlet looks like this (important info only).  The first
(non
pool) example works fine.  The second fails:

  try {
out.println("OK Here we go trying a regular
connection");
// Load the AS/400 Toolbox for Java JDBC driver.
DriverManager.registerDriver(new
com.ibm.as400.access.AS400JDBCDriver());

// Get a connection to the database.
// Note the use of PROPERTIES to specify the date format
used.
// Using the iso format keeps errors from generating on
*loval
dates
connection = DriverManager.getCo

The window that you see is the Console. The log files would be in
C:\Tomcat4.1.12\logs.

Yes, I got it to maximize but this looks like a Java Swing application.
Does the TOMCAT server write its log messages to any log file? Is there
a Java Console where we can see the server-side println?

Right click right on the top bar where you see C:\Tomcat\ etc., (ie
where you see the maximize, minimize, close (x) buttons).

 I agree System.out.println will work if its a normal Dos window. Here
it seems to be a Java Gui application which seems to startup and becomes
a minimized icon in the task bar. Right-clicking the icon does not show
a properties option.

Is there a way to see print messages from Servlets\JSP in a TOMCAT env.
Currently, when I startup TOMCAT in Windows 2000, the application runs
in a
small window which can't be maximized.

I'm using a JDBC Datasource with Tomcat 4.1.12 as follows.

Server.xml snippet:

  
  

  validationQuery
  select top 100 * from Subscriber


  url
 
jdbc:microsoft:sqlserver://vc34:1433;databaseName=TibcoClearHouse



  password

  maxWait
  5000


  driverClassName
 
com.microsoft.jdbcx.sqlserver.SQLServerDataSource


  username
  tibco_user


  maxIdle
  2

  

END OF Server.xml Snippet

When I cause a database access within my application, I get the
following horrifying result. It's the "Error Establishing Socket" error
that's worrying me, as I'm using the native Microsoft SQL Server
Drivers. The ones in my lib directory are msutil.jar, msutil.jar, and
mssqlserver.jar

Any thoughts?

Tomcat 4.1.12 on Dual Processor NT Box

[Hari Venkatesan]

We are planning to setup Tomcat 4.1.12 in a dual processor NT box. Are
there any special configurations issues that I need to address and any
tips that would avoid surprises. 
 
 
By the way I am new to Tomcat and setting up of App servers.
 
You inputs and advice would be appreciated
