Limiting Amount of Memory Tomcat use
Platform: Linux, Tomcat 3.3.1 Hi people, I am writing a JSP web services on an embedded system running Linux without swap space. Everytime I access a new JSP page, the amount of memory Tomcat uses increase. I think Tomcat is caching the new JSP page for faster access. Am I right? Is there a way to limit the maximum amount of memory that Tomcat will use? Can I configure Tomcat to cache only the last 5 JSP pages? Thanks In Advance. Raymond Pau -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: Tomcat 3.3.1 and additionalJars
The symptom you describe is easily achievable. The main point is that additionalJars adds jars to multiple webapps the same as if you copied jdom.jar to each WEB-INF/lib. You could try putting jdom.jar in your test webapp's WEB-INF/lib, remove the additionalJars, and see if the error still occurs. I would not be surprised if it did. If a servlet depends on another class that in turn depends on jdom.jar classes, and that class lives below the webapp classloader, then you might see the symptom you describe. The class in the lower classloader can't see the classes in the webapp classloader unless special programming is implemented to make it possible, such as using the thread context classloader.

It works on Websphere, but as you can see, initial conext is provided by Websphere code, and I won't use that in Tomcat (in fact I think this is EJB code, and Tomcat does not support it; I can't use it even if I want to).

Re: Is it possible to restart NT-based Tomcat 4.0 remotely?
Hi Umberto, if you run Tomcat as a service, try using the freely downloadable PSTools from http://www.sysinternals.com/ntw2k/freeware/pstools.shtml which contain the commandline utility psservice which lets you remotely control NT-Services. You might also be able to run the startup and shutdown Batch files remotely with the psexec utitlity (also included in the PSTools download) (Haven't tried it with Tomcat specifically I must admit) Joerg -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: just one edit.
I don't know if you can set some property in web.xml or system.xml of
tomcat to only allow only one user to access a web-app or some other kind
of resource at a time. I shouldn't think
there were as this is contactory to what people want a webserver to do.
But you could modify your webapp or bean or whatever to not let more than
one user edit some data at the time using context variables.
When some administrator enters the restricted code part (eg the part that
modifies data) a context variable (for instance called busy) is set, and
when he leaves the code part, or logs out or whatever, this context
variable is deleted. When the second administrator tries to access the
restricted code, he will check to see if the busy-variable is set and if
it is is rejected. Else he can enter.
However. You should read about concurrency problems first. (For instance
in a good book about Operating Systems) as this kind of monitoring has
many problems attached to it, and making a fail safe system like this is
hard at the best..

You'll probably want to synchronize on a static object I think. Something
like this:
public class WhatEver {
protected static Object lock = new Object();
public void doStuff() {

// do protected stuff here
}
}

RE: unable to serve static pages through apache web server (Tomcat 4.0 - Apache using AJP connector)
Hi, Looks like I found out the solution myself :). To serve static pages via apache instead of tomcat, all I have to do is set the attribute forwardAll=false for ApacheConfig listener in server.xml. Listener className=org.apache.ajp.tomcat4.config.ApacheConfig forwardAll=false/ Since the flag is set to true by default and my server.xml configuration did not include this attribute, all the pages(static as well as dynamic) were served by tomcat in the tomcat-apache service mode. thanks Paresh Deshpande ( Hey Scott, once again thanks for your workaround suggestion. ) -Original Message- From: Paresh Deshpande [mailto:[EMAIL PROTECTED]] Sent: Monday, May 20, 2002 08:47 PM To: [EMAIL PROTECTED] Subject: unable to serve static pages through apache web server (Tomcat 4.0 - Apache using AJP connector) Hello, I have installed Apache web server (Apache/1.3.24 (Win32) mod_jk/1.1.0) with Tomcat as servlet engine (Apache Tomcat/4.0.3) to serve my application. I am using AJP connector to integrate tomcat with apache installation. Now regarding my problem, all my requests for static content (gifs, html files) as well as for servlets in webapp folder end up getting served by tomcat (i.e. when I type url http://localhost:8090/app1/test.html , where localhost:8090 stands for apache web server and app1 for the webapp folder for app1, I see test.html which is served by tomcat). Is it possible for apache web server to load static pages and for tomcat to serve only the servlets? Reason I want to load static pages via apache is that tomcat is case sensitive even for the static pages. If I type http://localhost:8090/app1/test.HTml , I get page not found error (and the error is served by tomcat). And in earlier versions of apache/tomcat setup, the static pages were served by apache instead of tomcat. Question is how can the page now be loaded via apache web server?

FW: Anti-Alias Font Images on the Fly?
Hi, You can generate your image on an AWT graphics surface on the server, and use standard AWT drawing techniques, or Java2D, to make more complex images. You then need to serialise your image to a binary stream to send to the client. This can cause problems if your server doesn't have a graphical environment. Even though you can create graphics without popping up windows on the server, some graphics methods require that the host (the server) has a GUI: not generally a problem with Windows, but on a Linux/UNIX server, you need an X-Server or an emulation of an X-Server ... unless you're using JDK1.4, which provides headless mode (to create server-side graphics without an X-Server). To send your nice anti-aliased text images to the client, you need to set the appropriate content type (such as image/png) and use an output stream for the servlet response. To encode your images to the output stream, you can install the JAI (Java Advanced Imaging) API from Sun along with your JDK, which provides these methods, or if you're using JDK1.4, you could try the Image I/O API (included as standard) ; I haven't tried the latter, but it should work. Finally, creating such images demands a lot of resources (relatively speaking). You're best to try and cache the images to disk whenever you create them, and only replace them if the text to display changes. For subsequent requests, just copy the cached image to the output stream (by reading from an InputStream that points to the file in the cache). I've no example code unfortunately, but it is reasonably straightforward. -Chris - Original Message - From: Marc Elliott [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Friday, May 03, 2002 6:36 PM Subject: Anti-Alias Font Images on the Fly?

Help with streaming mp3
I have a very strange problem that I hope someone can help with. I have
a servlet that streams (using ServletOutputStream) various web and
media files (mp3, mpegs, etc..). The media files are not in the web
dir. This servlet is designed to restrict access to the media files.
For most files this works, but for mp3s, it is not working properly.
It's stream most mp3 fine, but about 20% of the time, it will have a 50
sec delay. There should be no delay (I'm on the same network). Other
files types (asf, mwf, mpegs, etc..) seem to work fine.
Below is the servlet code. I'm at a loss. Please help. :)
Oh, a few notes. 1) I'm using JBoss-2.4.4 with embeded Tomcat. 2)
This code work when I were using weblogic and seem to appear when we
ported to jboss. 3) we are using media player to play the media files.

Tomcat 4 problem?--Graphics randomly fail to load
Hi everyone, I've encountered a bizarre problem with Tomcat 4 stand-alone, regarding the loading of graphics. Some of the graphics for my site wil load, while others will not, as if they weren't located on the server. After thorough experimentation with what's NOT happening, I'm forced to believe that it's the server that's causing the problem. I searched the tomcat list archives and couldn't find a similar report, so I'm hoping that someone out there has experienced this anomaly. Your feedback is much appreciated. Just to clarify what is NOT happening: 1. The graphics (.gif format) are properly located on the server, in valid file formats, with correct permissions. 2. When forcing the server to load a graphic, either by selecting Show Picture from the browser's context menu or accessing a single graphic through a URL request, the graphic loads correctly every time. 3. This symptom may occur even on tiled images, such as body background graphics. Some of the tiles draw, while others do not. This symptom is present on IE5 and Netscape 6.2, tested on Win2k and MacOS X. 4. The problem occurs randomly; it does not seem to be predictable/reproduceable. A graphic will load correctly in one instance and fail to load in another. _ scott judd programmer the american education corporation

reloadable=true just not working. Any ideas gentlefolk?
Below is a snippet from my conf/server.xml file. From all the docs I've read, and the examples, this should work. However the tomcat class loader does not recognize newly compiled class files and still uses the cached versions. Can anyone spot a problem with the xml below? It parses upon startup.

Tomcat stops accepting connections with 218 java processes running
Hi guys, I have a nagging problem. I am running Tomcat 3.3 with Apache 1.3 on Redhat 7.2, kernel 2.4.17, Sun's Java 1.3.1 The problem I am having is that sometimes Tomcat refuses to spawn new java thread. If I look at the processes there would be exactly 218 java processes/threads running. Looks like this is the maximum number of processes Tomcat and/or java can spawn. Restarting Tomcat helps - until next time. I suspect that some .jsp and/or servlets do not properly quit/close/free resources and Tomcat still thinks they are running and cannot clear those threads up. Workaround, I thought, would be to bump up maximum number of Tomcat threads. I do restart Tomcat every night after logrotate, so I thought if I set maxThreads to something bigger than default (200, according to Tomcat docs), it would be enough to keep me running. Here is a snippet from my server.xml: Ajp12Connector port=8007 ajpidFile=/usr/local/tomcat/conf/ajp12.id address=127.0.0.1 maxThreads=1 tomcatAuthentication=false / Ajp13Connector port=8009 address=127.0.0.1 maxSpareThreads=10 maxThreads=400 tomcatAuthentication=false / Setting maxThreads for Ajp13 connector to 400 did not change anything. Still, every once in a while I will have 218 java threads an Tomcat will stop taking new connections. I have a couple of questions regarding this stuff: 1. How do I increase the number of Tomcat threads? Where does number 218 come from? 2. Is there any way to tell what each java thread running? This way I could tell programmers what ties Tomcat up so they can fix the code - I am not much of a programmer :-(. Am I looking in the correct direction at all? Could it be something completely different?

Syntax for turning off caching in Tomcat 4.0.3?
Hi, The Tomcat 4.0 documentation describes a parameter to turn off caching using the Resources component. The documentation appears at: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/resources.html However, we haven't been able to find an XML clause to add to server.xml that succeeds in turning off caching. For example, shouldn't this work?

I am using AJP connector to integrate tomcat with apache installation. Now regarding my problem, all my requests for static content (gifs, html files) as well as for servlets in webapp folder end up getting served by tomcat (i.e. when I type url http://localhost:8090/app1/test.html , where localhost:8090 stands for apache web server and app1 for the webapp folder for app1, I see test.html which is served by tomcat). Is it possible for apache web server to load static pages and for tomcat to serve only the servlets? Reason I want to load static pages via apache is that tomcat is case sensitive even for the static pages. If I type http://localhost:8090/app1/test.HTml , I get page not found error (and the error is served by tomcat). And in earlier versions of apache/tomcat setup, the static pages were served by apache instead of tomcat. Question is how can the page now be loaded via apache web server?

Re: reloadable=true just not working. Any ideas gentlefolk?
I don't have the answer to why reloading isn't working, but I can recommend using the tomcat manager app to remove and install your app to freshen it. That doesn't require a restart of tomcat. One important note though, if your webapp's main directly exists, this won't work. You have to blow away that directory after you remove.

Re: reloadable=true just not working. Any ideas gentlefolk?
I don't believe the class loader recognizes any new code other than servlets and jsp files. If you have new classes called by servlets, they won't be reloaded. If you search in the archives, you should find a lot of discussions on this topic. If you have servlets or jsp's that aren't reloading, I'm not sure what may be going wrong.

HttpSession invalidate bug???

Hi Chris, Session.invalidate() is being called by Tomcat on session timeout, which is the same call that is given when you implicitly invalidate the session in your servlet code. Once session.invalidate() has been called, you no longer have any session properties to get, including your session listener. Also, you're gonna need to add some properties to your session object to determine how/why the session was invalidated.

Subject: Re: HttpSession invalidate bug???
Hi Chris,
Session.invalidate() is being called by Tomcat on session timeout,
which
is
the same call that is given when you implicitly invalidate the session
in
your servlet code.
Sure that makes sense, that's what I understood was happening... I
don't think that's the problem though. I fully expect the session to be
invalid.
Once session.invalidate() has been called, you no
longer
have any session properties to get, including your session listener.
Also,
you're gonna need to add some properties to your session object to
determine
how/why the session was invalidated.
This is the problem... The Servlet spec implies (10.7) that you CAN use
at least some of the HttpSession API's to determine if the session is
invalid because it timed out. I assume that you would do that with the
following code...
if((System.currentTimeMillis() - session.getLastAccessedTime())
session.getMaxInactiveInterval()) {
// session timed out
}
If I run that code on an invalidated session the getLastAccessedTime()
call works just fine (the javadocs say that it does not throw any
exceptions) which is expected. However, the getMaxInactiveInterval()
call fails with an InvalidStateException (this is thrown even though the
javadocs DO NOT specify that it should be) which is not expected.
It seems to be that there is no way for me to determine if a session is
invalid (because it timed out) in a listener without
getMaxInactiveInterval(). Now either the spec (10.7) is referring to
some other combination of calls, or the javadocs are wrong, or Tomcat is
throwing an IllegalStateException when it shouldn't be (most likely).
So my question is if the Tomcat developers can justify why
getMaxInactiveInterval() should throw an exception when called on an
invalid session, how can I achieve section 10.7 in the spec?
Just using the API calls without any
support staff will not be sufficient.
Again, this is not what the spec implies. It says I should be able to
do it with HttpSession directly.
Thanks for the help!

Hello,
I'm having touble with my HTTP tunnelling servlet and its driving me crazy.
The tunnel works fine for a single user. However when another user connects
to the tunnel the servlet does not perform how I would expect it to.
The problem is, that when another user sends a message. ALL instances of the
variables seem to swap over to the most recent. However the threads still
all run. So, if mr x and mr y are in a meeting. Mr x joined first, he says
'hello'. Hello is sent and recieved once how I would expect it to do it.
However, now mr y joins and says 'hello'. and he recieves the messages for
himself AND for mr x.
This is driving me insane and I can't seem to find a way around it, I don't
understand why the entire data structure is being overwritten when it is a
different request for a different user. The sockets are different, yet when
i do the test, they aren't! But the server isnt sending the message out on
the wrong socket. I've tested that. It's somehow the right sockets,
recieving the right messages, but then sending them to the wrong place. But
how can this be? It makes no sense to me.
The code for the tunnel is below.

alright. leaving aside the issue of your subject line... I, too, am not reading all that code until I get a better idea of what you're actually asking.

That means that every request hits the same instance method, instance variables, etc, just as though they were static.

Without digging in too deeply, is it possible your problem is the cloning of the 'meet' Hashtable in connectUser? Remember that cloning a Hashtable (and other Collection/Dictionary objects) is a shallow clone. Only the table itself is cloned, not the objects pointed to by the table. I'm not *sure* that's a problem in this case, but is that what you intend?

Re: [Off Topic] HttpSession invalidate bug???
Chris, I can assure you that this is not a Tomcat issue. Let's try to take
it off-list from here. I have attached some code inline to this post which
will hopefully address, if not fix, your problem. See below:
- Original Message -
From: Chris Wilson [EMAIL PROTECTED]
Sure that makes sense, that's what I understood was happening... I
don't think that's the problem though. I fully expect the session to be
invalid.
But remember that if you call session.invalidate() on an already invalidated
session, it throws an IllegalStateException, which is symptomatic of the
problem you described. As a matter of fact, the session object is null after
being invalidated, whether programmatically or by the servlet container, so
getting any properties from a null object will return unexpected results.
:)
I assume that you would do that with the
following code...
if((System.currentTimeMillis() - session.getLastAccessedTime())
session.getMaxInactiveInterval()) {
// session timed out
}
Actually, I believe the correct convention here would be to use
getMaxInactiveInterval() when the session is valid, so that it's still
*legal* to get attributes from the session. Ideally, you would do this in
the valueUnbound() method of your listener class. I'm nearly positive that
this is occurring through a getAttribute() call in the ServletContext class
of the servlet container (which also throws IllegalStateException). After
the servlet container invalidates the session, all future references to the
session object will evaluate to null, thus causing the exception that you're
getting. Note that running this code snippet on WebSphere and JRun produced
a similar result as Tomcat. It's just plain not a server issue.
This statement would get you the same net effect as what you're describing
above:
if(session == null)
{
//handle session timeout
}
I'm happy to help you off-list if needs be. Email me at [EMAIL PROTECTED]

Control user access to directories in J-T ver 3.3 on unix?
Hi, please tell me if fine-grained user access control is possible in J-T, and if so, how to accomplish it. I'm using Jakarta-Tomcat version 3.3a on a solaris 8 box. I have access control enabled such that users of my app must supply a password; this uses a SimpleRealm with a local file of users and passwords as specified in the context for my webapp (in conf/apps-myapp.xml). To gain access to J-T/webapps/myapp, users enter a password. So the first line of defense is working. However, 'myapp' creates directories for each user under webapps/myapp where users store their work. Currently, an authenticated (but malicious) user can access the files for another user by guessing the appropriate URL under the J-T webapps/myapp/user directory. This is the hole we need to close. I'm asking about how to restrict access to specific directories. I have no need to restrict access on a file-by-file basis. We specify a role for the users, but it's not clear to me that the role information is used anywhere (?). I've read the SimpleRealm part of the Server.xml Configuration document. I have scanned the Tomcat Documentation, including the Tomcat User's Guide, the server configuration, etc. I've googled the question with little success (other than some security hole warnings). I sure hope that I don't have to create an instance of the webapp for each user! If it matters, we are using Apache as the front-end, and it forwards requests on to the J-T server as needed. Does this have anything to do with Slide (something Google turned up)?? (I don't mean to complain, but I sure would welcome some improvements in the J-T documentation. :-/) Thanks in advance, I look forward to hearing from someone. chris...

RE: just one edit.
Maybe it's best to rely on transactional mechanisms of the database.
Then you don't have to worry about locking in your application. When one
administrator A saves the data, the application could easily check if
data has been updated by any other administrator B (or perhaps a user)
since A began his editing, and notify administrator A about this.

You'll probably want to synchronize on a static object I think. Something
like this:
public class WhatEver {
protected static Object lock = new Object();
public void doStuff() {
sychronized( lock ) {
// do protected stuff here
}
}

Re: ***Please reply as no one on this list has offered ANY help***
Hi Stuart,
It looks as if you have a problem with instance variables (variables in a
class declared outside a method). All logins are going to be using the same
copy of the code, i.e. same variable space etc. All synchronizing does is
make sure that the threads play nice when modifying the variables.
Your Hashtable connections is an instance variable, so there is only one
copy of it for all calls to connections. When you fill connections with
data, another login may fill it again before you get a chance to copy that
data to a new object.
Also, all those instance variables at the top of your thread class
ToApplet are all shared by all instances of ToApplet. Every thread is
going to see what was stuffed into them by the last thread created.
Generally you should only do that for data that needs to be the same for all
threads and is initialized once and never changed.
In general, if you are storing anything in an instance variable you might
have problems. Create a class to hold data and use it instead.
As a simple example, instead of :
String myStr = req.getParameter(blaBla);
use:
StorageClass myData = new StorageClass();
myData.myStr = req.getParameter(blaBla);
That way, you are certain to get a clean one-owner copy of myStr for each
thread as long as you are careful to create and fill it in a sync block.
If you need another method to see your object pass it as a parameter.
The same thing will happen in a JSP if you create a class inside %! % and
then call that object's methods with variables in the main JSP page.
Although each call to the JSP will create a new class
Hope this helps,
Rick
Hello,
I'm having touble with my HTTP tunnelling servlet and its driving me
crazy.
The tunnel works fine for a single user. However when another user
connects
to the tunnel the servlet does not perform how I would expect it to.
The problem is, that when another user sends a message. ALL instances of
the
variables seem to swap over to the most recent. However the threads still
all run. So, if mr x and mr y are in a meeting. Mr x joined first, he says
'hello'. Hello is sent and recieved once how I would expect it to do it.
However, now mr y joins and says 'hello'. and he recieves the messages for
himself AND for mr x.
This is driving me insane and I can't seem to find a way around it, I
don't
understand why the entire data structure is being overwritten when it is a
different request for a different user. The sockets are different, yet
when
i do the test, they aren't! But the server isnt sending the message out on
the wrong socket. I've tested that. It's somehow the right sockets,
recieving the right messages, but then sending them to the wrong place.
But
how can this be? It makes no sense to me.
The code for the tunnel is below.

Tomcat 4.0.3 + mod_webapp + FORM authentication
Hi, I'm having a problem with authentication to my webapp when accessing it through Apache. I have my realm setup in server.xml to use JDBC (accessing a PostgreSQL database), and based the security constraints in my web.xml from the security example provided with Tomcat. - Apache is running on one machine (nova), and Tomcat on another (setsuna) - My webapp is at /opnexus under Tomcat, and my httpd.conf is set to redirect this same path to Tomcat (this all works fine) - Authentication works just fine when I access it directly through Tomcat - If I try to go to a protected page through Apache, authentication always fails, even if the username and password are correct. - The security example provided with Tomcat works fine when accessed through either Apache or Tomcat. I've looked through the list archives and seen this problem posted a couple times, but never any solution. If anyone has any suggestions that might help, I'd appreciate it. Thanks in advance.

Chris, I can assure you that this is not a Tomcat issue. Let's try to
take
it off-list from here. I have attached some code inline to this post
which
will hopefully address, if not fix, your problem. See below:
- Original Message -
From: Chris Wilson [EMAIL PROTECTED]
Sure that makes sense, that's what I understood was happening... I
don't think that's the problem though. I fully expect the session
to be
invalid.
But remember that if you call session.invalidate() on an already
invalidated
session, it throws an IllegalStateException, which is symptomatic of
the
problem you described. As a matter of fact, the session object is null
after
being invalidated, whether programmatically or by the servlet
container,
so
getting any properties from a null object will return unexpected
results.
:)
I understand that you can't call session.invalidate() on an invalidated
session--the javadocs support your claim. However, they do not say you
can't call getMaxInactiveInterval() on an invalid session (check them
out). Plus, your assertion that the session object is null doesn't make
sense, because I can successfully call session.getLastAccessedTime().
That should throw a NullPointerException if the session is null, however
it doesn't for me.
Here try this HttpSessionListner you'll see what I'm talking about
import javax.servlet.http.HttpSessionListener;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSession;
public class TestListener implements HttpSessionListener {
public void sessionCreated(HttpSessionEvent httpSessionEvent) {
}
public void sessionDestroyed(HttpSessionEvent httpSessionEvent) {
// ok session should be invalid here...
// lets test some assertions
// let put it in a try block to catch any exceptions
try {
HttpSession session = httpSessionEvent.getSession();
// lets make sure session is not null
System.out.println(session == null);
// ok lets try last access time
// this SHOULD work even if session is invalid
// javadocs say it will...
System.out.println(session.getLastAccessedTime());
// ta-da it does
// ok if that worked then this should work too
// javadocs do not say it throws IllegalStateException
System.out.println(session.getMaxInactiveInterval());
// whoops this busts...
// javadocs say this shouldn't happen
// Servlet spec (10.7) implies using this method to see if
// a session is invalid because of timeout as opposed
// to explicit call to session.invalidate();
// now, we won't get here cause the above fails
// but just to see if the session is invalid
// lets call something that the javadocs DO say should
// throw IllegalStateException on an invalid session
session.invalidate();
} catch(Exception e) {
e.printStackTrace();
}
}
}
I assume that you would do that with the
following code...
if((System.currentTimeMillis() - session.getLastAccessedTime())
session.getMaxInactiveInterval()) {
// session timed out
}
Actually, I believe the correct convention here would be to use
getMaxInactiveInterval() when the session is valid, so that it's still
*legal* to get attributes from the session. Ideally, you would do this
in
the valueUnbound() method of your listener class. I'm nearly positive
that
this is occurring through a getAttribute() call in the ServletContext
class
of the servlet container (which also throws IllegalStateException).
After
the servlet container invalidates the session, all future references
to
the
session object will evaluate to null, thus causing the exception that
you're
getting. Note that running this code snippet on WebSphere and JRun
produced
a similar result as Tomcat. It's just plain not a server issue.
This statement would get you the same net effect as what you're
describing
above:
if(session == null)
{
//handle session timeout
}
The problem with your example is that it doesn't tell me if the session
is invalid because session.invalidate() was explicitly called or because
it timed out. I hate to sound like a broken record, but the spec (10.7)
says determining the difference should be possible by calling methods on
the HttpSession (read it, you'll see).
Can any Tomcat developers weigh in on this?
Thanks for all your help!

Hello Thanks for the info Fabio! I will be using WebSphere version 4 and it has a connection pool setup in the server admin pages. I have yet to test my code under but I have set it up (db conn pool) and it seems quit easy. I should be able to use my data access code (which is pretty much the same as your example). BTW, which version of WS are you using? Thanks and sorry for being OT!! D Watson - Original Message - From: Fabio Mengue [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Tuesday, May 21, 2002 8:23 AM Subject: Re: Connection Pool Configuration Hi, I have the same problem. Want connection pool to work on Tomcat and Websphere without to rewrite code. IBM send us instructions to set up the server and a piece of code that looks like this: ... java.util.Properties parms = new java.util.Properties(); parms.setProperty(javax.naming.Context.INITIAL_CONTEXT_FACTORY, com.ibm.websphere.naming.WsnInitialContextFactory); javax.naming.Context ctx = new javax.naming.InitialContext(parms); javax.sql.DataSource ds = (javax.sql.DataSource)ctx.lookup(jdbc/db2proddb02DS); java.sql.Connection c = ds.getConnection(user,pass); ... It works on Websphere, but as you can see, initial conext is provided by Websphere code, and I won't use that in Tomcat (in fact I think this is EJB code, and Tomcat does not support it; I can't use it even if I want to). So I'm trying an alternate path: ... javax.naming.Context ctx = new javax.naming.InitialContext(); javax.sql.DataSource ds = (javax.sql.DataSource)ctx.lookup(java:comp/env/jdbc/db2proddb02DS); java.sql.Connection c = ds.getConnection(user,pass); ... And on /conf/server.xml !-- MyApp Context -- Context path=/myapp docBase=myapp debug=0 reloadable=true crossContext=true !-- Pool de Conexao DB2 -- Resource name=jdbc/db2proddb02DS auth=SERVLET type=javax.sql.DataSource/ ResourceParams name=jdbc/db2proddb02DS parameternameuser/namevalue/value/parameter parameternamepassword/namevalue/value/parameter parameternamedriverClassName/name valueCOM.ibm.db2.jdbc.DB2ConnectionPoolDataSource/value/parameter parameternamedriverName/name valuejdbc:db2:database/value/parameter /ResourceParams /Context I'm still getting a Null Pointer error, but I think that when I got it to work, I might use the very same configuration (and code) on both servers, since COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource it's not Websphere code. Hope it helps. And note that I may be wrong :) Perhaps one of the fine people in this list may correct me.

[Coyote] Coyote 1.0 Release Candidate 2 available
Coyote 1.0 RC 2 is now available, and includes: - HTTP/1.1 protocol handler - JK 2 protocol handler, with support for the AJP 1.3 protocol - An adapter for Tomcat 3.3.x - An adapter for Tomcat 4.x The only change over RC 1 is fixing compatibility with Tomcat 4.0.x. Note: The version of Coyote included in Tomcat 4.0.4 Beta 3 (Coyote 1.0 Beta 9) was not subject to this problem. Binaries can be downloaded at: http://jakarta.apache.org/builds/jakarta-tomcat-connectors/coyote/release/v1 .0-rc2/ Installation instructions for both 3.3.x and 4.0.x are given on the download page.

/manager doesn't work on Apache2.0 w/Tomcat4.0.3
Hi, I'm struggling with Tomcat4.0.3 with Apache2.0 these days and I need help to make it work. The problem is, /manager of Tomcat 4.0.3 doesn't work (see the error message below) when it is connected through Apache 2.0, while /manager works if only Tomcat4.0.3 is used. java.lang.SecurityException: Servlet of class org.apache.catalina.servlets.ManagerServlet is privileged and cannot be loaded by this web application. In addition, clicking Tomcat Documentation on Tomcat top page does stop working (the error message: The requested resource (/tomcat-docs) is not available), while adding / at the end of URL on the browser leads to Tomcat documentation page without any problem. Any modifications of the config-related files of both Tomcat and Apache2.0 don't help so far. I'm using the following packages on Dell PowerEdge1650 / RedHat7.2 (2.4.9-31smp): *the same sympton is observed on RedHat7.2 (2.4.7-10). - Apache 2.0 (httpd-2.0.36.tar.gz) - tomcat4-4.0.3-1.noarch.rpm - tomcat4-webapps-4.0.3-1.noarch.rpm - tomcat-connectors-1.0-1.4.0.2.src.rpm - xerces-j-1.4.4.-2.noarch.rpm - regexp-1.2-1.noarch.rpm - servletapi4-4.0.3-1.noarch.rpm The changes made in config-related files to connect from Apache2.0 to Tomcat4.0.3 are: - Apache o use port80 to access to Tomcat o add mod_webapp.so (generated from tomcat-connectors' src package) o add entries to httpd.conf LoadModule webapp_module modules/mod-webapp.so WebAppConnectionwarpConnwarplocalhost:8008 WebAppDeployROOTwarpConn/ WebAppDeployexampleswarpConn/examples/ WebAppDeploymanagerwarpConn/manager/ WebAppDeploytomcat-docswarpConn/tomcat-docs - Tomcat4.0.3 o disable all Connector in server.xml Tomcat Manager Context entry in server.xml is properly defined as: Context path=/manager docBase=manager debug=0 privileged=true/ and tomcat-users.xml has the entry of: user name=manager password=manager roles=manager/ Has anyone come across the same problem? Any suggestions would be appreciated. Thank you. Masako Kinoshita -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Tomcat multiple tomcats out of the same base directory
Could there be a problem using the web application or sharing the work directories. Is there a problem with running multiple tomcat instances out of the same base? Thanx Ganesh -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
