problem with multiple application on Tomcat

[puneet sachar]

To the technical team Tomcat ,

Sir I have a problem, I’m using tomcat server 3.3 ,
now I have 3 different application rather one
application witrh different version 
Say for client A I have some classes that is version
1.0
For client B I have some classes that is version 2.0
which have might have exactly same classes that is
present in version 1.o or modified classes as required
by client B and some extra classes
And for Client C I have version 3.0 which again might
have same classes or modified classes .

Now I problem is I have to run that application on
same tomcat server but I want different application
only respond to their classes 

Is it I have to add 3 different JVM for different for
different classes or different Servlets context for
different classes and how would I add 3 different JVM
in one container.

If u doesn’t follow my question please take this case
study

As I mention I have 3 different applications running
on my tomcat each have same class A
And Class A for client A prints “in client A”
For Class A for client B prints “in client B”
And For Class A for client C prints “in client C”

And suppose if class A is called by any one of client
which is print..

{According to me the class, which is set in class
path, is to be printed and I want classes should
respond to respective classes} 

Please Sir I ‘m stuck because of this problem looking
forward for your suggestions

Re: Tomcat RPMs?

[Gerrit Kuilder]

Hi Donald,

I also build my tomcat from RPM's, also hat no startup or other .sh's.


I got the scripts from the cvs tree but found out later that I don't 
need them. On redhat 7.1 I can start and stop with 'service tomcat4 
start' and 'service tomcat4 stop'.

I suppose the .conf file is used for setting JAVA_HOME etc.

the rpm's worked (and works) for me , althoug I have to go localhost:8180

[Donald Lee]

Thanks, it would have been nice to have a bit of documentation that referred to these 
new RPMs.  Since the docs I was using came from the RPMs themselves, they are 
obviously outdated.

In my case (Win 2K), System.out.println goes to the Catalina console window
that's spawned when Tomcat is started.

That will look ugly even though it's for the test purpose. Try
use the log file. You will more than likely need them in the
production environment unless that is not your preference
and no necessary.

If you want a debugger you can put in easier than using 
System.out.println("blah blah ..."), I include one you are welcome to use, 
but not sell, with this reply.  I use it all the time.  Essentially you 
just go (where "data" is the variable you want to test): new 
Debugger(true).add(data).log(true);  If you want to add lots of variables, 
new Debugger(true).add(data1).add(data2).add(dataN).log(true);  The  The 
value "true" in log(true) tells the application to save the last run of the 
log.  Using "false" as in log(false) would overwrite the last run.  You can 
figure out the rest easily enough.  There are a few rather obvious choices 
and all data types are overloaded and covered. Enjoy!

You need, of course, Sanjeev, to set the name of the jdk you are 
using.  The debugger class references the following class:

package tccjava;

public class JavaPlatform {
 public static final String version = "j2sdk1.4.0-beta3";
}

And, you need to set the path for you log files as show in the constructors 
of the debugger, using this JavaPlatform file.

Re: problem with multiple application on Tomcat

[Tom Drake]

Puneet:

The answer to your problem is simple. You can simply package 
and deploy each set of classes as a seperate web application 
with it's own context (e.g. a, b, and c). Under each context is 
a WEB-INF/lib directory that would hold the jar file that 
contains the correct versions of all the classes used by that 
clients application. 

This way, when your user requests a URL from context 'a', 
the servlet, jsp, bean, ... code that handles the request will be
loaded from the jar file in the 'a' context. Similarly for the the
other contexts.

This will all run under one JVM, but each context will be loaded
via a different class loader.

Unless I've completely misunderstood your question, this should
be all there is to it.

Good luck, and happy new year.

Tom

Missing Step in deployng TDk app?

[Ivo Zivkov]

I have a question about deploying the application.

I am using the latest Turbine TDK with Tomcat 4.0.1 on Linux. After
successfully building the sample ‘newapp’ in the turbine TDK, tomcat
reposted “Not fond error 404’ to the URL:
http://localhost:8080/newapp/servlet/newapp, even though I have correctly
set CATALINA_HOME variable. I can verify that TOMCAT is running properly,
because id displays its information when browser pointed to
http://localhost:8080  . The only way I could get it
to work is by making a link from the TDK directory:

$SOME_TDK_HOME/webapps/newapp

to the tomcat directory:

$CATALINA_HOME/webapps/newapp

I could then access the application using the URL
http://localhost:8080/newapp/servlet/newapp.

Was this step not supposed to be made automatically by the build process? Is
there anything special to be done to  make tomcat find the application. I
could not find anything that links the TDK application to the tomcat
directory.

Any help would be greatly appreciated.

Ivo Zivkov

You would probably get a better response from the turbine-user
mailing list.

The tdk comes with it's own tomcat (4.0b6 I think) and it should
fire up correctly if you use the startup.sh in /tdk/bin with
CATALINA_HOME set to /tdk

If you want to use tomcat 4.01 installed elsewhere you need to
copy webapp/newapp over to the 4.01 webapp directory or
use the link that you are already using.

Re: Tomcat 3.3: ThreadPool bug (IS IT SAFE FOR PRODUCTION USE???)

[Jeff Kilbride]

Hi Drasko,

Sorry, I haven't used Solaris in quite a while. I use FreeBSD and Linux most
of the time. I vaguely remember seeing posts about threading issues, but I
can't recall the problems.

I used the 3.2.x release successfully behind Apache before switching to 4.x.
I found that I didn't need Apache, except to serve static content -- no php,
perl, etc...  So, I moved to Tomcat standalone and now I run a faster,
smaller footprint webserver (thttpd) on port 81 to handle my images and
other static content. Unfortunately, you can't load balance this way without
an external solution.

Anyway, I took a look at the 3.3 ThreadPool code and I think the ThreadPool
configuration is actually being done in PoolTCPEndpoint.java in
org.apache.tomcat.util.net. This starts a pool (with the defaults) then uses
the setXXX methods to configure the Pool. When I was using 3.2.x, I remember
there being serious problems if the MAX_THREADS value was ever reached. For
heavy load, the way around it was to set MAX_THREADS equal to the number of
possible Apache child processes (MaxClients in httpd.conf). This way,
MAX_THREADS should never be reached -- hence, no blocking problem. You might
give this a try and see if it helps. It solved the problems I was having
with 3.2.x at the time.

Hope this helps.

Thanks,
--jeff

has the use of mod_webapp a file disclosure vulnerability?

[lupo]

Hello,

I just went the easy way to install Tomcat4 on linux via binary RPMs
(tomcat4-4.0-1, tomcat4-webapps-4.0-1) and configured my Apache/1.3.20
something like this:

DocumentRoot /var/www/virtual/testhost
ServerName www.testhost.dom

WebAppDeploy examples warpConnection /examples/



The Apache Webserver has some handlers configured:
AddHandler server-parsed .shtml
AddHandler send-as-is asis

Now if I request any URL ending with ".shtml", the Apache server
handles the request itself (what may be perfectly legal), but it
ignores the DocumentRoot!
So a request for "http://www.testhost.dom/var/www/html/index.shtml";
tries to serve the file "/var/www/html/index.shtml" which is not
contained in the DocumentRoot of that virtual host. The server seems
to take "/" as the new DocumentRoot. This behaviour occurs whether
the Tomcat engine itself is running or not.

Is this a problem of the Apache Webserver, a flaw of mod_webapp or did
I just do something completely wrong in my configuration?

regards,
Markus "Lupo" Volk

Turbine/Velocity abd PostgreSQL problem

[Ivo Zivkov]

Has anyone been able to get turbine and velocity to work with PostgreSQL? I
followed the instruction to build the sample application (newapp), and
applied the patch to the PostgreSQL JDBC driver as recommended here:

http://jakarta.apache.org/turbine/turbine-2/howto/postgres-howto.html

Still, I am getting the following errors in the app log file:

[Tue Jan 01 18:44:15 EST 2002] -- ERROR -- Error rendering Velocity
template: s\
creens/user/FluxUserList.vm: Invocation of method 'getUsers' in  class
org.apac\
he.turbine.flux.tools.FluxTool threw exception class
org.apache.turbine.util.se\
curity.DataBackendException
and:

uxUserList.vm: Invocation of method 'getUsers' in  class
org.apache.turbine.flu\
x.tools.FluxTool threw exception class

I understand it has something to do with velocity and PostgreSQL not
handling BLObs correctly, but has anyone been able to resolve this?

Tomcat, threads and garbagecleaner: A question

[Duarte Loreto]

   Hello!

I have a JSP page that instantiates an object. This instantiates another 
one, as a thread. The thread is created and started on the same inline, and 
I have no pointer to the thread.

My question is: when this thread finishes it's run(), does it get 
garbagecleaned? The object that referenced it was created by a JSP page that 
was already delivered to the client, so it should be, right?

I'm asking this as I have a server that, after some usage, starts to get 
slow and then completly freezes, needing a restart. I suspect that there is 
a memory leak somewhere, and this seems the most probable place.

If your answer is "the thread gets garbagecleaned, so look elsewhere for 
your problem", I would appreciate help on how to analyse memory usage. I'm 
clueless on this.

I'm using tomcat 3.2.3 and I run it on UNIX, with JDK1.3. If needed be, I 
can put it to run on a Windows, if you tell me that THE tool to check for 
the problem is windows-based

I appreciate your help. If you think that this question shouldn't be posted 
here but rather on the devel list, please notify me.

Re: Problem with Tomcat 4.0.1 installer: Cannot find JDK!

[Antonio Vargas]

Ion,
Yup! This certainly worked! I just had to add a string value:
CurrentVersion - 1.4 to both the JDK and the JRE keys.  Thanks a lot for
your help.

William,
Try adding a CurrentVersion string value to the
HKEY_LOCAL_MACHINE/SOFTWARE/JavaSoft/Java Runtime Environment key.
Following are my registry entries (they might help):

HKLM/SOFTWARE/JavaSoft/Java Development Kit
CurrentVersion = "1.4"
HKLM/SOFTWARE/JavaSoft/Java Development Kit/1.4
JavaHome = "C:\windows\jdk143"
MicroVersion = "0"
HKLM/SOFTWARE/JavaSoft/Java Development Kit/1.4.0 beta3
JavaHome = "c:\windows\jdk143"
MicroVersion = "0"

HKLM/SOFTWARE/JavaSoft/Java Runtime Environment
CurrentVersion = "1.4"
HKLM/SOFTWARE/JavaSoft/Java Runtime Environment/1.4
JavaHome = "C:\Program Files\Java\j2re1.4.0-beta3"
MicroVersion = "0"
RuntimeLib = "C:\Program Files\Java\j2re1.4.0-beta3\bin\client\jvm.dll"
HKLM/SOFTWARE/JavaSoft/Java Runtime Environment/1.4.0 beta3
JavaHome = "C:\Program Files\Java\j2re1.4.0-beta3"

Hi.

I too have experienced the same problem trying to get
Tomcat 4.0.1 to install on Windows when i *do* have a
valid Sun SDK (d:\jdk1.3.1_02). I have already checked
the registry as I suspected that this is where the
Tomcat installer is looking and the relevant entries
are there - yet i am still getting the same error
message from the tomcat installer as per the orginal
poster of this thread. The difference is that I am
using NT4SP6a so are there any other registry entries
i should be looking for?

Re: Tomcat 4.01, IIS and JSPs

[Daniel Parnell]

G'day Puneet,

There are a couple of limitations.  Only JSPs work, and Tomcat must be
installed on the same machine as IIS.
The JSPs are copied into the Tomcat root context for execution.

I've had a couple of requests for the code, so I've started a sourceforge
project for it.  With any luck it should be up in the next couple of days.

Re: Tomcat4.0:-Ignorance Of class path ::::oracle.jdbc.driver.OracleDriver ..

[Sachin Tyagi]

thanks ..
Its working...when classes12.jar file placed to
jakarta-tomcat-4.0\common\lib (WEB-INF/lib  it might be )  only...It does
not work when we place that file in \common\classes...that directory is for
what.

And on more thing is this mentioned some where that TomCat4.0  ignore the
complete CLASSPATH of system.because some other .jar files required for
my web application,  set in classpath are also not able to import...

So is this mandatory to place all .jar files in tomcat/lib...  which is
required for the application.??
Or
can we add classpath through scripts at Tomcat startup

There is a list of drivers in java.sun.com.  Also, you need to know if you 
are going to be using the java.sql.jdbc or the javax.sql.jdbc.  I recommend 
the latter.  Whatever will work with your jdk will work with tomcat or any 
other Java platform.
