Deployment specific configuration - best practice
Hi, I'm preparing a sample webapp for this list to illustrate a problem that I have with JDBC driver loading in a servlet. Anyone who'd try this would need to edit the jdbc connection data to test with a local DB. What is the easiest method for you to configure a webapp that I'll provide? * settings as init params in web.xml * settings in /META-INF/context.xml (both ways you'd need to upack, edit, repack and deploy) * a separate context file along with the war file * any other idea?

Not sure how to fully disable security but I added the following which I
understand should grand all rights to classes under my webapp:
1. grant codeBase file:${catalina.home}/webapps/nutch-1.0/- {
permission java.security.AllPermission;
}; in conf/catalina.policy
It should be
file:${catalina.base}/webapps/nutch-1.0/- {
2. /etc/init.d/tomcat6 restart
3. start webapp by admin
Still the same error...

You're running Tomcat with the Security Manager enabled.
Presumably the Ubuntu package automatically configures the Security Manager
in it's startup config. You should examine those files for more clues as to
how you can disable it.
If you can disable the Security Manager temporarily, see if the application
starts up. If not, send more error log info showing what happened and we'll
try to assist.
If it does, re-enable it and you'll have to to figure out what the
application is trying to do, then add appropriate permissions in
tomcat/conf/catalina.policy.
There's more information about the SM here:

Why do you need to provide a sample webapp? Usually if you post your database configuration, the exception that you are getting and the code where the exception is raised people should be able to figure out why there is a problem. :) On Mon, Nov 16, 2009 at 11:28 AM, Leon Rosenberg rosenberg.l...@googlemail.com wrote: On Mon, Nov 16, 2009 at 9:26 AM, Rainer Frey rainer.f...@inxmail.de wrote: Hi, I'm preparing a sample webapp for this list to illustrate a problem that I have with JDBC driver loading in a servlet.

Webapp reload and DriverManager in Tomcat 6.0 trunk
Hi,
I found a problem when using DriverManager.getConnection() with a build from
current 6.0 SVN (this morning). Basically I have a Servlet that's loaded on
startup and does following in its init() method:
try
{
Class.forName( driver );
}
catch( ClassNotFoundException x )
{
log( x.toString(), x );
}
Connection con = null;
try
{
con = DriverManager.getConnection( url, user, pass );
log( connection established: + con.toString() );
}
catch( SQLException x )
{
log( x.toString(), x );
throw new ServletException( x.toString(), x );
}
After starting Tomcat, I get the following expected output:
Nov 16, 2009 1:56:11 PM org.apache.catalina.core.ApplicationContext log

I tested with Java 6 (1.6.0_17) and JDBC 3 and 4 Drivers for Oracle

Everything works fine with Tomcat 6.0.20.
The error originally occured in a much more complicated application with a
home-grown DB connection pool, but the servlet I mentioned above exhibits
this behavior. For anyone willing to test: here is a .war file with this
servlet, please edit web.xml to fill in your DB connection details.

I'm testing our application for compatibility with the upcoming 6.0.21
release, so I'd be grateful if s.o. could try to verify whether this is a
Bug, so it has a chance to be addressed before 6.0.21
Thanks, and sorry for the lengthy message

Tomcat DBCP Connection Pooling to MySQL limited number of connection issue in Spring2.5 + Hibernate3 + commons-DBCP1.2
Hi,
I am using Spring 2.5, Hibernate 3 and MySQL (5.0.45 (32 Bit), 5.0.84(64
Bit)) with commons-DBCP 1.2 in Tomcat-5.5
My issue is that even after specifying Connection pool of initialSize=40
and minIdle=35, my App. server is never keep only 9 connections open under
zero load condition. What I could figure out from the MySQL log was that,
server did created 40 connections, but also dropped each connection in 1-2
seconds after connection started. I have max_connection=200 in MySQL, and
time to keep idle connection in MySQL is also 8Hrs.
Under load, App server creates connections upto 95 as I have described
it as maxActive=95
I confirmed it thru show global status and show processlist on MySQL
prompt while simulating a heavy traffic thru JMeter.
I tried with c3p0 from Hibernate, but no luck. Outcome is exactly same.
So am wondering what the issue is ??
My bean definition is as follows for DBCP:

seconds after connection started. I have max_connection=200 in MySQL, and
time to keep idle connection in MySQL is also 8Hrs.
Under load, App server creates connections upto 95 as I have described
it as maxActive=95
I confirmed it thru show global status and show processlist on MySQL
prompt while simulating a heavy traffic thru JMeter.
I tried with c3p0 from Hibernate, but no luck. Outcome is exactly same.
So am wondering what the issue is ??

jdbc-pool ignoring minIdle ?
Hi all,
I have seen a strange behaviour with the new Tomcat jdbc-pool (1.0.7.1).
It seems to ignore the minIdle parameter.
I have been able to reproduce it with a simple program.
minIdle is set to 5 and after a few seconds, I don't have any idle
connection left.
Could anybody confirm the bug or point the mistake in my configuration ?
Thanks in advance.
Best regards,
Xavier.
Here is the test program :
public class TestPool {
public static void main(String[] args) throws Exception {
PoolProperties p = new PoolProperties();
p.setUrl(jdbc:postgresql:XXX);
p.setDriverClassName(org.postgresql.Driver);
p.setUsername(login);
p.setPassword(password);
p.setDefaultAutoCommit(false);
p.setJmxEnabled(false);
p.setTestWhileIdle(true);
p.setTestOnBorrow(true);
p.setValidationQuery(SELECT 1);

RE: AccessLogValve calling order
Uh, if the Access Log Value logged before the request was complete, how
would it know the number of bytes written to log?

Subject: Re: AccessLogValve calling order
Hi Chris.
Thanks for diagnosing this problem! It appears you're right that it
logs
only after the session is invalidated (after the request is complete)
on a
logout request. That bug has existed in the code for a very long time,
unnoticed. The AccessLogValve was initially implemented to log only
after
the request processing is complete so that the client never needs to
wait
for the logging to complete. With the new addition of asynchronous
logging,
however, it's quite a bit less important to log only when the request
is
complete. It seems like it would help if the access logger could be
configurable to log either before or after handling the request (I'm
not
sure logging both before and after makes sense). Your ideas for %Sr
and
%{methodName}rm both seem useful as well, though I think the
%{methodName}rm
one has potential security side effect issues. So, I would suggest
implementing your first two ideas. I'm also happy to help you with
that, if
you'd like.
Cheers.

All,
Amazingly enough, I had my first need to use AccessLogValve today,
and
one of the things I wanted to print was the user's session id. No,
problem: just add %S to the log pattern.
Well, there is one problem: you can't spit-out the session id for
logout
requests because the logic for the AccessLogValve is:
if(enabled)
invoke next valve
print log message
else
invoke next valve
Note that the request has essentially completed when the log message
is
generated. This makes complete sense as you typically want to log
/after/ the request so you can do things like find out how many bytes
were sent, how long the request took, etc.
In my case, I want to have access to the session id before the
session
is invalidated (which happens in the logout servlet).
Another option would be to get the requested session id from the
request
(which can only be done with the current AccessLogValve if the client
is
using cookies), though that can be misleading because anyone can
request
anything... it's not guaranteed to use a useful value.
Anyhow, I was wondering if anyone had any suggestions short of
heavily
modifying the AccessLogValve or developing something from scratch.
I'd also be happy to provide a patch for the AccessLogValve that add
any
or all of the following capabilities:
1. Allow log before or after request (or both?)
2. Add requested session id to standard pattern options (%Sr?)
or
3. Add %{xxx}rm to call ServletRequest.xxx and print the result
(allows ${getRequestedSessionId}rm
Any comments?

Re: jdbc-pool ignoring minIdle ?
hi Xavier, the pool is not ignoring the minIdle flag, but you have
configured
p.setMaxAge(43200);
This means,that if a connection has been connected longer than this,
next time you call con.close() it will be closed and not returned to the
pool.
The connection pool itself at this point in time will not create a new
connection. Only when you actually call getConnection() may another
connection be created.

Possible to do async processing?
Hi! We are using tomcat 6.0 and now we have the need to trigger from the service() method of a servlet.

Yes, there is a way, and I suspect you're doing fire-and-forget processing, but, could you give us a better idea as to what you are trying to do? Tomcat will handle servlet requests in multiple threads if needed, anyway. So it may not be necessary. I'm thinking you might want to investigate a messaging system, such as OpenMQ. BTW: To create a thread by hand, look at the Java docs for the Thread class and the Runnable interface.

Some advice on apache tomcat
Hi, I am in need of some advice. My current setup is a web application running on Jboss which serves static and dynamic content, jsp, servlets and xml on two non load balanced servers (hot spare using mysql replication). It currently uses Http Basic Authentication over SSL. This has been fine to date but since I dont use any of EJB or related features I think that it is overkill for my application, as well as being unflexible w.r.t. deployment and content management as the whole site is deployed as a single EAR. Initially it was fantastic as it was simple and easy to maintain but now every change requires a full build. I am researching porting my site to Apache 2.2 and Tomcat, and hope to gain the following. 1. Serve the static content from apache e.g. images, clips sound, text files etc. 2. Install a CMS to offload content managment to others and also blog functionality, Wordpress seems to be the tool of choice for ease of usage and widespread usage, this seems to work fine in my test environment. 3. Maintain current servlet and jsp (including xml) functionality on tomcat. Instead of one super application I can deploy servlets as seperate applications and update them seperately. 4. Use connectors such as mod_jk to load balance and provide failover. I already have heartbeat and mod_jk installed on in high availabilty mode using workers in a test environment and this is working as expected. (Apache 2.2 and tomcat 6 running on centos 5.3). At this point I have hit a brick wall w.r.t. what to do next. I have been researching this for the past two weeks and the more I learn the more I seem to be confused. There is so much documentation on some things but almost none on others. I always fear that if there is nobody asking questions about a certain topic it either means that a) There are no problems using the technology or b) Nobody is using it at all. My main issue now is about how the authentication works between Tomcat and Apache. I would like to use both Form based and http basic authentication on protected resources running on both apache and tomcat. i.e. Form based for humans and httpbasic for XML requests over ssl. I have a user database in mysql containing username and password, roles are in another table but these could be merged if required. I also am confused by mod_jk and mod_proxy_ajp, they, seem to have much feature overlap. mod_proxy_ajp in my view suffers terribly from the missing *.jsp wildcard capability but has a much simpler configuration and better future prospects as it is bundled with apache 2.2. In terms of authentication, which should I use, mod_auth_mysql and mod_auth_dbm (or mod_auth_form in future or something else?) and why? In terms of single sign on how can I make the user experience seamless between static content-managed pages and jsp/servlets? Will mod_jk handle sso? This does not seem clear to me in all the pages I read. If I configure form based auth in a login.jsp page will this be relayed to apache after a redirect? What is best practise and what should I be doing? If there is some hard to find documentation out there with pointers and tips I would appreciate a few links. Expert advice is appreciated.

Tomcat 6.0 requires JRE 5.0 issue
Hi, does anyone know what the 'official' Apache explanation is for the contradictory information in Tomcat 6 README and RELEASE-NOTES: When you open http://apache.crihan.fr/dist/tomcat/tomcat-6/v6.0.20/README.html , you get this message: Tomcat 6.0 requires JRE 5.0. Read the RELEASE-NOTES and the RUNNING.txt file in the distribution for more details. If you open RELEASE-NOTES you will see=== Dependency Changes: === Tomcat 6.0 is designed to run on JSE 5.0 and later From the Release Notes I gather that I can use Java 6 (which is what a lot of developers do, so I know it works). But, what does “Tomcat 6.0 requires JRE 5.0” imply? That Tomcat 6 will only be supported with Java 5, but one can run it on Java 6 at their own risk? I mean, if I have a Tomcat problem while running Java 6, will my bug be considered for fixing? Should the warning be removed from the site? If yes, how do we make that happen? My company has a policy to deploy only officially supported platforms, and I can’t move to Java 6 with Tomcat while “Tomcat 6.0 requires JRE 5.0” is there.

RE: Possible to do async processing?
A pretty simple way of doing this is to have your context init create a background thread. Have the background thread monitor a queue for jobs. Then, have the servlet place the job in the queue. The background thread can either process the job itself, or create a worker thread to process the job.

RE: Possible to do async processing?
Sorry.. misunderstood your original when you asked if there was a way to create a Thread by hand No tricks/shortcuts. Are you saying each request will take a minute to process and is triggered a few times an hour? I suspect the client is anxiously awaiting a response like OK, I got it, but not patient enough for a The request was successful. I'm still thinking a messaging system, especially if you want to requests to be processed regardless of the time the message was delivered, like, when maybe many requests hit near the same time. A quick hack on a messaging system is to simply have the servlet throw a record into a DB, file or something used as a messaging queue. Then, a program external to Tomcat simply monitors the queue, picks up any existing requests, handles them, and starts monitoring again. This way, Tomcat could go down without affecting if the messages are processed, or the monitor could be down without affecting if Tomcat can push in new requests. The only thing that can't go down is the queue.

RE: Some advice on apache tomcat
Hi Neil, Thanks for the comments, I really appreciate hearing from someone that has actual production experience using these technologies! To answer your question below, I *could* have all my servlets in one webapp but that would not be my preference. For example I would like the capability be able to update a single servlet that serves XML without affecting any other user interations with the server, or, more realistically, to completely deploy a new application inluding jsp/servlets into Tomcat as a customer beta and keep current applications unaffected. (We have several new applications under development!) In addition Some servlets need http basic, some form based auth and others not even ssl at all! So from your mail I understand that you only use apache to serve static pages that are not protected, thereby needing no authentication and therefore you can contain all your Auth using Tomcat. This is good, how do you handle ssl? Does Apache terminate any SSL, all ssl or only static pages?

Hi Chris.
Thanks for diagnosing this problem! It appears you're right that it
logs
only after the session is invalidated (after the request is complete)
on a
logout request. That bug has existed in the code for a very long time,
unnoticed. The AccessLogValve was initially implemented to log only
after
the request processing is complete so that the client never needs to
wait
for the logging to complete. With the new addition of asynchronous
logging,
however, it's quite a bit less important to log only when the request
is
complete. It seems like it would help if the access logger could be
configurable to log either before or after handling the request (I'm
not
sure logging both before and after makes sense). Your ideas for %Sr
and
%{methodName}rm both seem useful as well, though I think the
%{methodName}rm
one has potential security side effect issues. So, I would suggest
implementing your first two ideas. I'm also happy to help you with
that, if
you'd like.
Cheers.

All,
Amazingly enough, I had my first need to use AccessLogValve today,
and
one of the things I wanted to print was the user's session id. No,
problem: just add %S to the log pattern.
Well, there is one problem: you can't spit-out the session id for
logout
requests because the logic for the AccessLogValve is:
if(enabled)
invoke next valve
print log message
else
invoke next valve
Note that the request has essentially completed when the log message
is
generated. This makes complete sense as you typically want to log
/after/ the request so you can do things like find out how many bytes
were sent, how long the request took, etc.
In my case, I want to have access to the session id before the
session
is invalidated (which happens in the logout servlet).
Another option would be to get the requested session id from the
request
(which can only be done with the current AccessLogValve if the client
is
using cookies), though that can be misleading because anyone can
request
anything... it's not guaranteed to use a useful value.
Anyhow, I was wondering if anyone had any suggestions short of
heavily
modifying the AccessLogValve or developing something from scratch.
I'd also be happy to provide a patch for the AccessLogValve that add
any
or all of the following capabilities:
1. Allow log before or after request (or both?)
2. Add requested session id to standard pattern options (%Sr?)
or
3. Add %{xxx}rm to call ServletRequest.xxx and print the result
(allows ${getRequestedSessionId}rm
Any comments?

Keep in mind, this could get really out of hand if there are a lot of requests and you don't understand how to properly manage threads in this environment. Yes, that is why I ask. (I know how to create threads). I would advise you not to create your own threads. Instead, use a thread pool and queue your jobs into that. 3rd-party thread pools exist, or you can use the ones available in Java 1.5+ in the java.util.concurrent package. You can get started by reading the javadoc for java.util.concurrent.ThreadPoolExecutor and going from there. So Tomcat has nothing like this in itself? Any trick , shortcut? Nope: Tomcat does not provide any services like this. It will be something triggered like a few times in an hour and would take less than a minute to process, to there should be no overload problems (famous last words...) :) That's why I recommend against managing your own threads: if you do it wrong, you can build a denial-of-service vector into your webapp. Using a managed thread pool can help save you from shooting yourself in the foot. Another option would be to queue the job in a database, then run a completely separate process to go and process them batch-style. This solution can even process jobs that were queued but not processed before you took the server down for some reason. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAksBvL4ACgkQ9CaO5/Lv0PDOYACfbdxU+QpIuwSz06Z0c/HHFUjs Pq0An3fNU9rGzjc2YZnFrw4E4TY4ngf7 =xAyX -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I already have heartbeat and mod_jk installed on in high availabilty mode using workers in a test environment and this is working as expected. (Apache 2.2 and tomcat 6 running on centos 5.3). At this point I have hit a brick wall w.r.t. what to do next. I have been researching this for the past two weeks and the more I learn the more I seem to be confused. What are you confused about? There is so much documentation on some things but almost none on others. I always fear that if there is nobody asking questions about a certain topic it either means that a) There are no problems using the technology or b) Nobody is using it at all. There are lots of questions about mod_jk on this list each week. Sometimes they're even different ones. ;) My main issue now is about how the authentication works between Tomcat and Apache. It's one way, Tomcat, as an 'inner' component, can defer to authentication set at the outer level in Apache HTTPD. See the tomcatAuthentication attribute of the AJP connector. http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html Tomcat can't pass it's authenticated principal up to HTTPD. I would like to use both Form based and http basic authentication on protected resources running on both apache and tomcat. You would probably need to seperate those parts into separate applications as FORM and BASIC can only be set once in each web.xml. (You can of course duplicate the same class or jar in differently configured web apps.) i.e. Form based for humans and httpbasic for XML requests over ssl. I have a user database in mysql containing username and password, roles are in another table but these could be merged if required. I also am confused by mod_jk and mod_proxy_ajp, they, seem to have much feature overlap. mod_proxy_ajp in my view suffers terribly from the missing *.jsp wildcard capability but has a much simpler configuration and better future prospects as it is bundled with apache 2.2. They offer similar, largely overlapping functionality, you choose one or the other. mod_proxy_ajp can of course handle *.jsp, when combined with mod_rewrite and the [P] proxy rewrite command. RewriteRule ^/(.+)\.jsp(.+)? ajp://tomcathost/$1.jsp$2 [P,L] In terms of authentication, which should I use, mod_auth_mysql and mod_auth_dbm (or mod_auth_form in future or something else?) and why? Up to you. In terms of single sign on how can I make the user experience seamless between static content-managed pages and jsp/servlets? Will mod_jk handle sso? This does not seem clear to me in all the pages I read. If I configure form based auth in a login.jsp page will this be relayed to apache after a redirect? If you're using FORM (or BASIC) as your primary auth, then HTTPD should only serve unprotected content, as additional auth will be required. What is best practise and what should I be doing? If there is some hard to find documentation out there with pointers and tips I would appreciate a few links. Expert advice is appreciated.

In terms of single sign on how can I make the user experience seamless between static content-managed pages and jsp/servlets? Will mod_jk handle sso? This does not seem clear to me in all the pages I read. If I configure form based auth in a login.jsp page will this be relayed to apache after a redirect? No, but why would it be ? Ah, if you want to do the authentication in Tomcat rather than in Apache, but still use it in Apache ? There are ways, but you'll need to write your own Apache (httpd) authentication module. You could then define a dummy servlet in Tomcat, which just echoes the authenticated user-id (as gotten via getRemoteUser() e.g.). Then in Apache httpd, you would make a side-request (oherwise known as a sub-request) to this Tomcat webapp to get the user-id, and use it to authenticate the current request in Apache. But that is a complicated scheme, probably only worth it if you find some Tomcat authentication method that does not exist in Apache httpd, which is unlikely. What is best practise and what should I be doing? If there is some hard to find documentation out there with pointers and tips I would appreciate a few links. To read in the Apache httpd docs : http://httpd.apache.org/docs/2.2/howto/auth.html Also, personally I would recommend having a look around here : http://cpan.uwinnipeg.ca/search?query=apache%3A%3Aauthmode=dist This is the Perl library. Even if you do not intend to do anything with Perl, the documentation of many of these modules is a goldmine of information about how things work. Expert advice is appreciated.

Re: Possible to do async processing?
Hi,
The advices given above are good. If you make this job triggered by a
servlet, then an attacker can use it to easily bring down your system
with excessive load.
You also have problems of clean shutdown. The thread pool that you
start needs to have blocking shutdown with some context listener, to
make sure that all jobs are finished when you undeploy or shut down
the server. This is not hard to do, but you should test it by making
sure a job finishes when you shut down. Just add a slow job that, and
kill the server.
Slow job:
public void run(){
System.out.println(Starting slow job);
try{
Thread.sleep(6); // 1 min
}catch(Throwable e){
e.printStachTrace();// possible kill, watch out for this
}
System.out.println(Finished slow job);
}
Add this job to the pool, shut down the server, and look at the logs
for the messages. You should also see the server hanging until the job
is completed.
A simpler option would be to write a java class with a main method,
and run it from cron. We have a bunch of those. Not dependent on
tomcat, no security problems. You can have many tomcats with the same
configuration, something that would be more difficult with a scheduler
that is part of your app.

You can also look at squid to serve static files and load balance. So squid fronts tomcat and your other apps. Squid can serve your static files as well. All you have to do it make sure your static files return a cache header like max-age, and squid will serve them without going to the origin (tomcat). Squid can also load balance tomcats and route requests for multiple origins based on some rules. We have squid doing virtual hosting of tomcats that run different apps, as well as serving static content and caching dynamic content. The down sides vs apache: 1. Not as many plugins and options 2. The configuration rules are simpler and more widely known/understood in apache 3. Hard to rewrite URLs. Not impossible, but mod rewrite is much much easier to deal with.

You can try getting an object dump from a profiler and see which objects are the source of memory starvation.

If you application does not use sessions, disable them for all JSPs (typical place to do it is header JSP include) 4. Force session termination, no long running sessions. 5.

Re: Java Out of Heap Issue
What I have found works well in some circumstances where you do not have a profiler to hand. 1. Look for static declarations in your code that point to singletons or collection objects. They might just grow and grow 2. You may not be using third party libs correctly, e.g. Not closing connections, performing cleanup etc. RTFM just in case. 3. Perform amputations on your code if possible i.e. replace methods with dummy invocations. You will *eventually* find the source of festering objects that are not being gc'd.

Re: Some advice on apache tomcat
Thank you very much for your informative comments. In terms of breaking an application into single servlets, I agree that there would need to be strong reasons for doing it, and the clear one that springs to mind is the requirement to have different authn methods for each, None, Form, and http basic. But I take your point on board. I really want to leverage as much flexibility between apache and tomcat but keep the dependencies and configuration to a minimum. I dream of a time where I can be lazy in the future. (Fat chance) Is there a lack of form-based authentication module (production ready) for apache or am I just really bad at finding things? I would really like to force apache to do as much as possible of the ssl and authn and leave tomcat to handle the actual work!

My current setup is a web application running on Jboss which serves static and dynamic content, jsp, servlets and xml on two non load balanced servers (hot spare using mysql replication). It currently uses Http Basic Authentication over SSL. This has been fine to date but since I dont use any of EJB or related features I think that it is overkill for my application, as well as being unflexible w.r.t. deployment and content management as the whole site is deployed as a single EAR. Initially it was fantastic as it was simple and easy to maintain but now every change requires a full build. I am researching porting my site to Apache 2.2 and Tomcat, and hope to gain the following. 1. Serve the static content from apache e.g. images, clips sound, text files etc. 2. Install a CMS to offload content managment to others and also blog functionality, Wordpress seems to be the tool of choice for ease of usage and widespread usage, this seems to work fine in my test environment. 3. Maintain current servlet and jsp (including xml) functionality on tomcat. Instead of one super application I can deploy servlets as seperate applications and update them seperately. One servlet per application probably isn't an optimal solution. Breaking a single large app into smaller components may be worth it - very much depends on your application. 4. Use connectors such as mod_jk to load balance and provide failover. I already have heartbeat and mod_jk installed on in high availabilty mode using workers in a test environment and this is working as expected. (Apache 2.2 and tomcat 6 running on centos 5.3). At this point I have hit a brick wall w.r.t. what to do next. I have been researching this for the past two weeks and the more I learn the more I seem to be confused. What are you confused about? There is so much documentation on some things but almost none on others. I always fear that if there is nobody asking questions about a certain topic it either means that a) There are no problems using the technology or b) Nobody is using it at all. There are lots of questions about mod_jk on this list each week. Sometimes they're even different ones. ;) My main issue now is about how the authentication works between Tomcat and Apache. It's one way, Tomcat, as an 'inner' component, can defer to authentication set at the outer level in Apache HTTPD. See the tomcatAuthentication attribute of the AJP connector. http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html Tomcat can't pass it's authenticated principal up to HTTPD. I would like to use both Form based and http basic authentication on protected resources running on both apache and tomcat. You would probably need to seperate those parts into separate applications as FORM and BASIC can only be set once in each web.xml. (You can of course duplicate the same class or jar in differently configured web apps.) i.e. Form based for humans and httpbasic for XML requests over ssl. I have a user database in mysql containing username and password, roles are in another table but these could be merged if required. I also am confused by mod_jk and mod_proxy_ajp, they, seem to have much feature overlap. mod_proxy_ajp in my view suffers terribly from the missing *.jsp wildcard capability but has a much simpler configuration and better future prospects as it is bundled with apache 2.2. They offer similar, largely overlapping functionality, you choose one or the other. mod_proxy_ajp can of course handle *.jsp, when combined with mod_rewrite and the [P] proxy rewrite command.

I changed some logger settings, but it didn't show me anything so I went ahead and grabbed the tomcat source so I could determine if there was any logging to be seen or if I had misconfigured the logging.properties file. I checked the Connector class to find out where I should log and found the check for APR support.

MISC; Tomcat-5.5.12; After one Tomcat Cluster node shutdown, sessionDestroyed been called before contextDestroyed
Dear all, I am using Tomcat-5.5.12 as Clustering nodes, and after one node shutdown sessionDestroyed is called before contextDestroyed. How can I know if sessionDestroyed is called from session.invalidate() from the real expiration of the session or shutdown of one cluster node? Note that on sessionDestroyed event, I am using a Logout behavior to logout my users from the DATABASE. I have tried to set a KEY on the context (or application scope) to check on it during the sessionDestroyed event, but it seems the context is destroyed after the session destroy event. Is there any event listener that I can use before the sessionDestroyed to differentiate if one cluster node has been shutdown or my session has been expired? Or is how to configure the contextDestroy to be called before the sessions destroy? Thanks in advance for your help.

Heap Usage: PS Young Generation Eden Space: 44.77395311745898% used From Space: 56.0% used PS Old Generation 38.96393638004623% used PS Perm Generation 69.73343814711973% used None of the above show full heap utilization, so the heap dump you have does not seem representative of the situation you describe. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Tomcat - Xms and Xmx size
Chuck: Not quite true; a 32-bit Windows environment normally has a 2 GB process space, and everything has to fit within that - Java heap, C heap, code, stacks, etc. If you have 3.5 GB RAM in the machine, I would set the heap no larger than 3 GB. Not possible on a 32-bit Windows system. You are correct. Everything I do is on 64 bit systems now so I don't pay attention to those limits anymore. Thanks for keeping me honest!

Re: Tomcat DBCP Connection Pooling to MySQL limited number of connection issue in Spring2.5 + Hibernate3 + commons-DBCP1.2
Hey,
Thanks Chris, That was just a typo. Thanks for pointing it out. But in real
configuration was was not commented. It was some other config which I was
trying and forgot to uncomment it in posting.

Your bean appears to be almost entirely commented-out. Is this your real

Cannot Start Apache Tomcat 6 service
Running Windows 7 - 64 bit o/s Installed the following: Jdk - 6u18-ea-bin-b04-windows-adm64 Jre-6u18-ea-bin-b04-windows-adm64 Apache HTTP Web Server 2.2.14 Tomcat 6.0.20 After completing Tomcat install - cannot start Tomcat 6 service. Checked Tomcat log: Jakarta_service_20091116 and noted the following - [174 javajni.c] [error] %1 is not a valid win32 application [994 prunsrv.c] [error] failed creating java c:\program files\\java\jre6\bin\server\jmv.dll Any suggestions would be greatly appreciated. I am thinking it may have something to do with the 64 bit o/s but not sure. Ron
