Re: application reloads on web.xml change
Please submit a documentation change. Historically, only reloadable was being done. This caused a lot of questions as to why changes in web.xml were not being picked up. As some refactorings came, it became easier to perform a stop, then start on the webapp instead of classloader reload. -Tim Bill Stilwell wrote: Hello, I was unsure if this or -dev was the best place to send this, so I decided to go with user first. I recently spent some time tracking down why we would get application restarts when code changes were pushed to our production environment, despite having reloadable=false in the DefaultContext. Via some digging around in the source, it turns out that if you have liveDeploy=true and web.xml is modified, the application will be stopped and started. Personally, I find this behavior unexpected (and, as far as I can tell, it's not in the user documentation). I can achieve what I expect with liveDeploy=false and reloadable=false, but I think it would be much clearer for users if only the reloadable setting was required to achieve no reloading unless done explicitly via the manager or at restarts. The relevant code is here: http://cvs.apache.org/viewcvs.cgi/jakarta-tomcat-4.0/catalina/src/share/org/apache/catalina/startup/HostConfig.java And the method checkWebXmlLastModified() is what controls this behavior. The original version of this code respected the reloadable setting. Is this worth filing a bug w/patch to request a code change? Or am I better off submitting a documentation change - i.e., are my expectations here out to lunch? :-) Thanks Bill - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Include tag, dynamic param
2 things
1) Are you trying to use el? If so you need a $ in front of {. You also need
your web.xml to state that you are using el.
2) For the RT expression - make sure you tag lib declaration allows runtime

For both of the above - there are plenty of net articles on the specifics of
how this is done.

Context/DefaultContext Question
Thanks to all who responded to my OutOfMemoryError post. Among other things, it was suggested that I look at the reloadable attribute for the context definition. We define a DefaultContext in server.xml, with the reloadable attribute explicitly set to false. We also have, for each application, a separate context definition file, for which the reloadable attribute is explicitly set to true. I'm a little confused about these two work together. We have a JNDI resource set up in the DefaultContext for e-mail (see the mail/Session example in the JNDI Resources HOWTO) that is actually called mail/Session, with the mail.smtp.host parameter set to localhost. In the application-specific context, this same resource is defined by the same name, but with mail.smtp.host set to a different value. The application always uses the value defined in the DefaultContext. Is this because the same name is being used, and once something is defined in the DefaultContext, it cannot be overridden by an app-specific Context? Going back to the reloadable attribute, is each context that sets this overriding the value in DefaultContext? Thanks, Dhruva __ Do you Yahoo!?

RE: Context/DefaultContext Question

In fact I'm surprised you don't get an error in the logs when you try to define another JNDI resource with the same name. For most other properties, including reloadable, last set stays set.

RE: SessionListener
Howdy,
Senor Basu, your solution is seriously not thread-safe. But that's for
you to worry about it, maybe it's good enough for your needs ;)
As for Senor Hart's questions:
- HttpSessionListener goes in web.xml, as do all other Servlet
Specification listeners.
- SessionListener goes in server.xml, as do all other Tomcat-specific
listeners.
SessionListener is not tied to HttpSessionListener or HttpSession
directly. You have to do a series of casts. The event object in the
SessionListener's SessionEvent is a catalina-specific Session
implementation. It will also implement the HttpSession interface. So
you can get from one to another by casting, but it's ugly (as is the
whole SessionListener solution).
Let's step back a minute: you have this whole hassle because you want
the user's password. You want the user's password in order to
authenticate the user. But with the getUserPrincipal approach, the user
is already authenticated if the Principal is not null. Alternatively,
if you have some input screen where the user enters the username and
password, grab them there instead of from the session. I think what's
missing here is the big picture: tell us what you're trying to do, what
authentication mechanism you're using, and let's forget about the
tomcat-specific hacks for a minute ;)

Hi,
Here is how I use the HttpSessionListener.
First I create a Class that implements HttpSessionListener:
package com.gri.web;
import javax.servlet.http.*;
public MySessionListener implements HttpSessionListener
{
private static int num_sessions = 0;
private HttpSession session = null;
public void sessionCreated(HttpSessionEvent se)
{
num_sessions++;
session = se.getSession();
}
public void sessionDestroyed(HttpSessionEvent se)
{ num_session--;}
public static int getNumSessions() {return num_sessions; }
public static HttpSession getLastSession() { return session;}
}
Now include this in the web.xml for your context (directly after
filterfilter-mapping but before Servlet element):
|listener|
||| listener-classcom.gri.web.MySessionListener/listener-class
/listener||
now all you have to do is create a JSP:
jsp:root xmlns:jsp=http://java.sun.com/JSP/Page;
jsp:directive.page import=com.gri.web.* /
jsp:text
html
body
|Last user in session:
/jsp:text
jsp:expression
MySessionListener.getLastSession().getAttribute(j_username)
/jsp:expression
|jsp:text
|Username of current person
/jsp:text
jsp:expression
session.getAttribute(j_username)

A SessionListener of the org.apache.catalina variety would go in the
same place as all tomcat-specific features:
$CATALINA_HOME/conf/server.xml. That means the class specified there
must be accessible to the server classloaders, i.e. must reside in
common/lib or higher on the classloader hierarchy.
The above is true for Valves, Realms, Listeners, etc, that are
proprietary to tomcat.

When you dump a ClassLoader and all of it's object get GC'd, the VM almost never GC's the unused classes. The new ClassLoader re-loads all those classes, again, and you get new versions of those classes loaded into the VM. Even if there are no more instances of those classes, I thought they stuck around... I was not suprised by anything mentioned in that bug. The only thing that's a shame is the fact that it's true, and it does interfere with the ability of an app server to re-load contexts indefinately. :( The -Xnoclassgc option still exists for the 1.4.1 VM, so maybe I'm completely wrong, here. :) -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Argument Type Mismatch
I was reading through the code, the session has a note on it with the password. I actually already wrote a custom realm implementation... I wanted to join the sessions all by using the session ID, which the realm doesn't have, which is why I figured at the creation of the session would be the best place. Honesly, I've already replaced a bunch of classes with my own, trying to do so without changing any Tomcat source, (by referencing them in through configuration). Since it's for a commercial project, and I don't think that we'll be wanting to give away the source (Does the Apache license require that?). I was considering extending GenericPrincipal in just such a manner in order to achieve that effect... 1 problem, is that safe security wise? Principal seems to get passed around a lot.

Ensure that jkjni.so picks up serverConf value from environment! The easiest
way for me was to edit /etc/tomcat/tomcat4.conf and add:
serverRoot=/etc/httpd/2.0
export serverRoot
If you're not using RPM version, just make sure that *that* variable is defined
in the script starting tomcat. This is needed by jkjni.so, so it can locate
workers2.properties. And if you're wondering, jkjni.so is needed to talk to UNIX
domain socket. Tomcat can open it without using handler apr and jkjni.so, but
refuses to communicate over it.

Setup your Apache side of JK2. Edit ${serverConf}/worker2.properties file. You
must define socket channel, ajp13 worker and at least one URI mapping to your

RE: SessionListener
Howdy,
Basic authentication. I figured it wouldn't be hard with Form
authentication, but I'm using basic in order to match the look and feel
of
the rest of the site.
OK, so you have basic authentication. Do you have a security-constraint
defined in web.xml? A login-config? You can let tomcat do the
authentication for you, and then use the HttpServletRequest methods
(getRemoteUser, getUserPrincipal, isUserInRole). This is a standard,
easy, portable way, and you don't have to write any custom tomcat code.
Your webapp will not have access to the user's password, but you won't
need it either since the container will authenticate it for you.
Does that fill your needs?

Howdy,
Senor Basu, your solution is seriously not thread-safe. But that's for
you to worry about it, maybe it's good enough for your needs ;)
As for Senor Hart's questions:
- HttpSessionListener goes in web.xml, as do all other Servlet
Specification listeners.
- SessionListener goes in server.xml, as do all other Tomcat-specific
listeners.
SessionListener is not tied to HttpSessionListener or HttpSession
directly. You have to do a series of casts. The event object in the
SessionListener's SessionEvent is a catalina-specific Session
implementation. It will also implement the HttpSession interface. So
you can get from one to another by casting, but it's ugly (as is the
whole SessionListener solution).
Let's step back a minute: you have this whole hassle because you want
the user's password. You want the user's password in order to
authenticate the user. But with the getUserPrincipal approach, the
user
is already authenticated if the Principal is not null. Alternatively,
if you have some input screen where the user enters the username and
password, grab them there instead of from the session. I think what's
missing here is the big picture: tell us what you're trying to do, what
authentication mechanism you're using, and let's forget about the
tomcat-specific hacks for a minute ;)

Hi,
Here is how I use the HttpSessionListener.
First I create a Class that implements HttpSessionListener:
package com.gri.web;
import javax.servlet.http.*;
public MySessionListener implements HttpSessionListener
{
private static int num_sessions = 0;
private HttpSession session = null;
public void sessionCreated(HttpSessionEvent se)
{
num_sessions++;
session = se.getSession();
}
public void sessionDestroyed(HttpSessionEvent se)
{ num_session--;}
public static int getNumSessions() {return num_sessions; }
public static HttpSession getLastSession() { return session;}
}
Now include this in the web.xml for your context (directly after
filterfilter-mapping but before Servlet element):
|listener|
||| listener-classcom.gri.web.MySessionListener/listener-class
/listener||
now all you have to do is create a JSP:
jsp:root xmlns:jsp=http://java.sun.com/JSP/Page;
jsp:directive.page import=com.gri.web.* /
jsp:text
html
body
|Last user in session:
/jsp:text

Howdy,
A SessionListener of the org.apache.catalina variety would go in the
same place as all tomcat-specific features:
$CATALINA_HOME/conf/server.xml. That means the class specified there
must be accessible to the server classloaders, i.e. must reside in
common/lib or higher on the classloader hierarchy.
The above is true for Valves, Realms, Listeners, etc, that are
proprietary to tomcat.

How will the container get my user logged into the database? My plan was to use the

I wanted to use session ID, which I don't have in the realm, instead, I use their

it will share a database connection, meaning I open fewer database connections (of

RE: OutOfMemory Exception initializing page context
Howdy, Once you're out of memory, the system is in a bad state and must be restarted. You will see error messages that are at best meaningless and at worst misleading, because they will make you look in the wrong places. You want to fix the memory issue first, by adding more memory (via the -Xmx java command-line parameter) or fixing a memory leak if there's one in your application. Do not assume, for example, that the IllegalStateException you cite has anything to do with the OutOfMemory error: it may be a misleading message thrown by the system after it ran out of memory (even though it shows up before the OutOfMemoryError in the log) while it was thrashing to GC stuff by invalidating your sessions.

Re: SessionListener
Justin, Won't quite do it, JDBCRealm looks for users in a database, I want to connect a user TO a database using their credentials, but the code to do this feat will be quite minimal by comparison. This will make it hard to use a connection pool (which you mentioned that you do/want to do). Is there a particular reason for the database access paranoia? Most apps connect to the db using the same login regardless of the user actually logged in to the application. They use other types of permission checking to see if you can perform some action, instead of relying on thr database for that kind of checking. I absolutely agree that having multiple layers of security is great, but this one may make your application suck really bad, especially if you are using a db like Oracle, where the database connections are anything but lightweight. -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Most apps connect to the db using the same login regardless of the user actually logged in to the application. They use other types of permission checking to see if you can perform some action, instead of relying on thr database for that kind of checking. I absolutely agree that having multiple layers of security is great, but this one may make your application suck really bad, especially if you are using a db like Oracle, where the database connections are anything but lightweight. -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Configure tomcat for LDAP
Hi, i want to use LDAP to athenticate my users on a JSP application and would like to know how to configure TOMCAT so that i can acces the login of the current user through a jsp ? for now, i have it all set on apache, in the virtual host using ath_ldap . my problem is that the request.getRemoteUser() method always returns null in my jsp application... but apache writes the login of the user in the acces.log so i guess it is a conf problem with tomcat... Does anyone have an idea, or a url that could halp ?? thanks in advance --- le présent message (ainsi que ses éventuelles pièces jointes) peut contenir des informations confidentielles.

RE: Configure tomcat for LDAP
JNDIRealm can be used to authenticate users against an LDAP (I'm guessing in this case ActiveDirectory).

Re: OutOfMemory Exception initializing page context
Rob, Well I have had my -Xmx set to as high as 1gb and I still receive these errors. The site will stay running for at best 1 day without crashing. I was just hoping one of these could point me in a direction while I work on looking at memory leaks. Sorry for the levity. Try this: Turn on verbose GCs, and make sure you're sending stdout to a log file (Tomcat does this by default, I think). Empty the stdout log file, restart Tomcat and then let it run out of memory. Take a look at the GC output (they are prettty obvious) and see what's happening to memory. I've done this in the past, and I even wrote a (long lost) Perl script to parse the log file and generate X-Y coordinates that I could plot using Excel. We could plainly see that there was a memory leak of some kind because the graph kept going up and up. It does take a long time to find memory leaks but there are a couple of things you can check. First of all, what JSK are you using? Check some of the following: - Are you starting any of your own threads? If so, are they dying when the context reloads? - Are you reloading the context a lot? - Do any of your container objects like hashtables or whatever keep references to things like the ServletContext, etc.? - Do you regularly remove old objects from users' sessions? - Are you doing any XSLT? - Are you using a database connection pool or are you creating new connections for each user? - Do you keep any persistent connections like sockets or anything open? -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Here goes.
STEP 1
--
Build mod_jk2.so and jkjni.so - do whatever needs to be done :-)
STEP 2
--
Place mod_jk2.so and jkjni.so with other Apache modules. In case of Mandrake
9.1, it was in /usr/lib/apache2-extramodules
STEP 3
--
Setup your Apache virtual host. Although you can run without it, I prefer
going
the right way. In my case:
/etc/httpd/conf.d/75_mod_jk2.conf

#
apr.NativeSo=/usr/lib/apache2-extramodules/jkjni.so
request.tomcatAuthentication=false
channelUnix.file=${jkHome}/work/tomcat.sock
STEP 6 !!!
--
Ensure that jkjni.so picks up serverConf value from environment! The
easiest
way for me was to edit /etc/tomcat/tomcat4.conf and add:
serverRoot=/etc/httpd/2.0
export serverRoot
If you're not using RPM version, just make sure that *that* variable is
defined
in the script starting tomcat. This is needed by jkjni.so, so it can locate
workers2.properties. And if you're wondering, jkjni.so is needed to talk to
UNIX
domain socket. Tomcat can open it without using handler apr and jkjni.so,
but
refuses to communicate over it.
STEP 7
--
Setup your Apache side of JK2. Edit ${serverConf}/worker2.properties file.
You
must define socket channel, ajp13 worker and at least one URI mapping to
your
virtual host. Needless to say, VHost definitions on Tomcat and Apache must
(should?) match.

AW: Servlet as Welcome File doesn't work
Hi I found an solution to force tomcat 4.1.29 to use servlets as welcome files. My applications web.xml: servlet servlet-nameRoot/servlet-name servlet-classcom.osiris4.servlets.Root/servlet-class /servlet servlet-mapping servlet-nameRoot/servlet-name url-pattern/root/url-pattern /servlet-mapping welcome-file-list welcome-fileroot/welcome-file /welcome-file-list The problem on this was that tomcat checks for the very existence of the file root, before actually invoking the servlet. The trick is to simply have an empty file root in the applications docRoot directory. If this is a problem for you, simply use another name for that file - e.g. use the servlets name. Thanks your answers anyway. Steffen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
load-on-startup and multiple coyotes
Hi, once again, after having just solved the welcome-servlet problem (posted separately) I just run into another problem. I have 5 distinct servlets while all inherit from a common base class whose simple purpose is to initialize the applications database pool, read different configuration files and preload some very important information from the databse. The servlets base class also takes care of synchronization and single database pool initialization. This all works very well as long as I have no load-on-startup set. It also works well with no load-on-startup but instead having only one coyote connector assigned to the application. This is were the problem comes in. I need to have 2 coyotes. One for http and one for https. As soon as I start using 2 coyote connectors together with load-on-startup tomcat initializes the database pools twice. Interestingly it keeps initializing things twice even if I add a third coyote. Anyone any glue so far? I even don't know where to look for this. Any hint would be welcome. Thanks, Steffen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: load-on-startup and multiple coyotes
Howdy, As soon as I start using 2 coyote connectors together with load-on- startup tomcat initializes the database pools twice. Interestingly it keeps initializing things twice even if I add a third coyote. You have one load-on-startup tag for each servlet element in web.xml, and one servlet element in web.xml for each servlet class, even when you have multiple connectors in server.xml, right? Tomcat (4.x) will create an instance of your servlet for every servlet tag in web.xml. Each instance will be initialized, so that may be what you're seeing.

Re: load-on-startup and multiple coyotes
Steffen, As soon as I start using 2 coyote connectors together with load-on-startup tomcat initializes the database pools twice. Interestingly it keeps initializing things twice even if I add a third coyote. In about two minutes, Yoav Shapira is going to tell you this: Don't use a servlet to initialize your stuff. Instead, use a ContextListener. IT's cleaner, more flexible, and only gets loaded when it should get loaded. I used to have InitServlet-style initialization, but now I use ContextListeners. They're pretty easy: create a new class that implements javax.servlet.ServletContextListener. Once you move your code from your old InitServlet, you have to install it into the web.xml file like this: listener listener-classfully.qualified.InitListener/listener-class /listener Put this section right before any servlet definitions but after any filter and filter-mapping sections you have. -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Tag Handler pool eating up Memory (and enablePooling is set to false)
Chris: Yeah, it's possible (and probable) that the TagHandlerPool maintains a reference back to the ServletContext in which it lives. That might kew your results. I'm sure that the TagHandlerPool isn't actually taking up that much memory. This is strange. When I created a heap dump from my server just now, it does not have any instances of TagHandlerPool in the heap dump. That is what I expected before, but I still had them in my last dump. Do you have any of your own tag libraries, or are you using only 3rd-party taglibs? If you are using your own, check to see if you are holding on to references or something like (anything like shared objects between tags -- that kind of thing). We are not using any 3rd party tag libraries. We are using our our tag library. I will look into that. If you have a profiler handy (something more robust that the heap dumper), check to see how many instances of various types there are. For example, if you are using org.foo.bar.taglib, then filter the object list by org.foo.bar.taglib and take a look at how many instances there are. If you find that there are thousands of references to tag handlers, then something is probably wrong with Tomcat. Otherwise, several hundred references doesn't sound horrible. It's possible that they haven't been GC'd yet.

I've heard that this version (it might only be the Sun distro -- can someone confirm?) has an implementation of StringBuffer that has a terrible memory leak. You might want to consider upgrading to 1.4.2 if that's possible. I ran some code to count all of the instances of java/lang/StringBuffer and the total bytes they hold both in themselves and their references. I got 2,925,512 bytes in 15,914 instances of java/lang/StringBuffer. The heap dump shows 174,740,832 total bytes used in 892,512 total instances.

Question using JProfiler with Tomcat
Hi, I'm using Jprofiler to monitor my web application running on Tomcat. My Webapp uses XML/XSLTC to generate the html page. Looking at the JVM, I was horrified to see that some pages are using more than 30 Mo of memory. So, I've added another webapp that shows the JVM ( graphic in a applet ). This applet shows differents values from Jprofiler about memory consumption. The used memory is not so much. I think it is due to the fact that Jprofiler creates a lot of objects to inspect the JVM. So my conclusion is : Don't use Jprofiler to see our much memory your web application use ! Or divide the obtained values by 3 or 4. What's your opinion about that ? Thanks

So you have 60k in SetPropertyTag objects? If you use them a lot (without pooling), then you'll get a lot of them on the heap at any given time. Can you observe that the number keeps going up, and never goes down? I find it very hard to believe that we have over 2500 active instances of our tags. This seems to imply they are not being garbage collected. Not necessarily. It might just be that they are taking a while to get GC'd. Again, what do you observe over time?

RE: Question using JProfiler with Tomcat
Howdy, Never use a profiler for absolute values such as how much memory an object takes or how much time it takes to do a certain operation. The time and memory are severely (often orders of magnitude) skewed by the profiler. Instead, use relative values as appropriate (e.g. 30% of the time is spent in this method, rather than 30ms to do the method, or this last change provided a 10% improvement in memory usage rather than a 10MB reduction). What are Mo of memory? MB and a typo I guess?

Can Tomcat really run cgi scripts?
I've been trying for last day to get Tomcat 4.1.12 to run a perl cgi script. I've done most of it based on this article: http://www.fawcette.com/javapro/2003_03/online/perl_teden_03_18_03/default_p f.aspx. But now I'm stuck with this error: java.io.IOException: CreateProcess: perl C:\Tomcat4112\webapps\examples\WEB-INF\cgi\exp.cgi In researching this on google I've found that a number of people have run into siimilar problems. Some of them solved it by adding Apache to the mix. I don't want to add Apache if I don't have to. So what I'm wondering is if anyone has had much success running perl scripts from cgi directory without using Apache? And also does anyone know how to get around the above error? Thanks, Ken P.S. The only reason I'm having to run perl is that I need to add iptc info to jpeg files and I've only found perl methods for doing so. If anyone can point me to a Java method of doing so I could avoid this problem for the time being.
RE: OutOfMemory Exception initializing page context
I consulted with the developers and they said we don't use or do anything that you suggested except we do use tomcat's connection pooling for oracle. We are running Sun j2sdk1.4.2_02 with the Concurrent Mark Sweep GC with -Xmx512m. I currently use the verbose logging for GC times. The odd thing is that it does not seem to progressively go up but rather spike up with high GC times and the full GC will not clean anything out.

Re: OutOfMemory Exception initializing page context
Rob, I consulted with the developers and they said we don't use or do anything that you suggested except we do use tomcat's connection pooling for oracle. Okay, that's good. Sometimes, people don't use connection pooling or do it improperly, and leave Connection objects lying around. SQL Connection objects do not clean themselves up nicely, if they even clean themselves up... We are running Sun j2sdk1.4.2_02 with the Concurrent Mark Sweep GC with -Xmx512m. I currently use the verbose logging for GC times. The odd thing is that it does not seem to progressively go up but rather spike up with high GC times and the full GC will not clean anything out. Hmm... that's a little odd. You say you get huge, sudden spikes from which the GC cannot recover? That sounds like bad news. Do you have any data on which pieces of code (servlets, JSPs, actions) are being executed when this happens? Consider adding a request logger filter to see what might be causing the spike... -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Can you reproduce the errors in a test environment? Are you using the context reloading feature? reloadable=true or using the tomcat manager app will cause this to happen eventually. Really?

But, I heard that this is still the case in 4.1.x. To reproduce this problem just reload a context over and over. Depending on how much memory it uses, it will start throwing OutOfMemory exceptions long before the -mx JVM parameter value is ever reached. eg. I do a ps on linux and it shows it as using like 140M or something like that and it already starts throwing out of memory exceptions. With our applications that we're running, we can usually get away with roughly 5-10 context reloads. calls Runtime.freeMemory() and .totalMemory(), it comes nowhere near using that much (we track it every five minutes by hitting a servlet that calls these methods). It could easily happen that: - You check memory, everything is fine - User makes a request for a large dataset, you load it, run out of memory. So your check is not conclusive.

deployment quirk in Tomcat5. Bug?
When deploying war files in Tomcat-5.0.16, I noticed something a little odd. After using the ant manager deploy task and then doing an undeploy, manually dropping the war file into CATALINA_HOME/webapps trigger auto-deployment. For example, say I have myapp.war. I just drop this into Tomcat5's webapps directory and it deploys the app as expected. I can do an undeploy via the html manager interface and it undeploys as expected. I can repeat this ad- infinitum and everything works fine. Now, I deploy myapp.war via the ant manager deploy task and it deploys as expected. Then I undeploy it with the html manager interface. Now I try dropping the war file manually into webapps as explained above. This time, the war does not deploy. If I restart Tomcat5, manual deployment works fine again...until after the first time I use the ant manager deploy task, of course. I can't imagine this is expected behavior. Well, at least I didn't expect it. Can anyone else confirm what exactly expected behavior is before I report a bug on this?

RE: Tomcat 4.0.x memory leak (not javac)
Howdy, You don't have to know much about the tomcat under the hood to diagnose this. It's not a problem with the tomcat classes. What you need to know is: - What 3rd party libraries does your application use - What classes stay in memory after a reload and have a 2nd instance of them created. You can use a profiler like Senor Hanik suggested (JProbe, OptimizeIt, etc.) to find out the latter. You want to look for a list of objects whose instance count increases after a reload of your webapp. OptimizeIt can do heap snapshot deltas which are the perfect tool here.

All I was asking what how to set the display name for a given path in that table.

That says memory leak to me although it doesn't specifically say that. 2. You mentioned in your passage the bug was marked as invalid or wontfix, and the bug you gave below is marked as new. So if anyone actually wasted time (like me) looking up what you said, they didn't find it. All I did was search for memory leak under Tomcat 4 and all status. I was not positive that it was marked WONTFIX, I should have clarified that in my original message. I had thought that the issue was something inherent to the design of Tomcat 4 (which was overhauled in Tomcat 5), but I'm sure that they are willing to accept patches if anyone can fix it. ;-) Bugzilla is obviously not working sometimes. I searched for memory leak one time and got it. Then I went to search for it for someone else so I could give them the bug number but nothing came up. I did the exact same search, memory leak. Very interesting indeed. Heck, I even searched for just memory or leak once each and came up with nothing. -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] __ This communication is intended for the use of the recipient to whom it is addressed, and may contain confidential, personal, and or privileged information.

Re: OutOfMemoryError
Trenton, Are you using the context reloading feature? reloadable=true or using the tomcat manager app will cause this to happen eventually. Really? Prove that please... Actually, I can't prove it in his instance, but I have proved it time and time again on ours. I'm using 4.0.4 right now though so I haven't verified 4.1.x. But, I heard that this is still the case in 4.1.x. To reproduce this problem just reload a context over and over. Depending on how much memory it uses, it will start throwing OutOfMemory exceptions long before the -mx JVM parameter value is ever reached. eg. I do a ps on linux and it shows it as using like 140M or something like that and it already starts throwing out of memory exceptions. Aah. I think I see a part of the problem. First of all, the amount of memory shown by 'ps' is completely irrelevant, except that it shows how much memory that the OS has allocated to the Java process. This is allowed to be more than the max heap size set for Java. The heap is not related to the amount of memory the OS allocates, except that the OS report will always be larger than the heap report from Java. You can get an OOM even if you have the heap set to 1GB and yet the process only has 50MB used. This is because OOMs usually happen *while the GC is doing its work*. I'm not sure if there's another thread that increases the actual size of the heap for you, but if so, I'm sure it's related to the GC anyway. So, moving on, what usually happens is that a low memory condition triggers a GC (usually a full GC). When the GC runs, it needs some memory to work with. If it cannot allocate memory for itself, it will die with an OOM. If the heap hasn't increased, yet, then the GC cannot allocate more objects on the heap to do it's thing. That can explain why you get an OOM when you are way under the heap size in the output of ps. With our applications that we're running, we can usually get away with roughly 5-10 context reloads. Do you have any 3rd party containers or such that live outside of the context (their JARs would be in CATALINA_HOME/server/lib or CATALINA_HOME/common/lib -- someone please confirm that the second of these two does *not* get discarded along with the rest of the context upon reload). If you are using 3rd party containers like this, they will not dump their contents when you re-load the servlet context. If you have static singleton instances of these, then you'll likely fill up memory all the time. This could also be related to the Java doesn't GC java.lang.Class objects thread that's going around this week, too. -chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Windows Serive Permissions?
It seems the problem with this lies with JRE1.4. When we loaded 1.3 and ran it, it worked. Anyone know of a workaround for the exec method hanging when using JRE 1.4 (besides using 1.3).

I have a command-line utility I am running that converts files into PDF. Here is the line we're using to run the program: Process proc = Runtime.getRuntime().exec(cmd.exe /c C:\\BatchPDF.exe +rtfFile.getAbsolutePath()+ +pdfFile.getAbsolutePath()); The problem is, it only runs if Tomcat was started from the startup.bat file. If Tomcat is running as a service, which is how we want it, it does not run. We set up Tomcat to run under administrator with no luck. We are guessing this is a file permissions problem, either from running it as a Windows service or with Tomcat itself. Any ideas would be appreciated.

4.1.29 tar file Cannot find message resources under key org.apache.struts.action.MESSAGE
I am getting this error returned to my browser when accessing http://10.1.1.1:8080/admin org.apache.jasper.JasperException: Cannot find message resources under key org.apache.struts.action.MESSAGE at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) This is from an out-of-the-box install i.e. I downloaded Tomcat version 4.1.29.tar.gz from http://jakarta.apache.org/site/binindex.cgi then unzipped and untarred the entire contents to my root directory. I discovered that the reason for the error is that the servlet is unable to find org.apache.webapp.admin.ApplicationServlet.class Turns out the tar file appears to contains a lot of very long pathnames which are truncated if they exceed 100 bytes e.g. jakarta-tomcat-4.1.29/server/webapps/admin/WEB-INF/classes/org/apache/webapp/admin/ApplicationServle I don't see a tar option that gets around this. Is this just my version of tar that's doing this? Or is it a problem with the tar file? Could someone verify it e.g. tar tvf jakarta-tomcat-4.1.29.tar
EL and XML escaping
Is there way to specify if EL expression in the body of a jsp page should be
escaped? Consider the following:
%
request.setAttribute(message,It is a igreat/i day);
request.setAttribute(equation,10 4);
%
${message} !-- xml escaping should be off --
br/
${equation} !-- xml escaping should be on --
Thanks

[OT] Role-based security, how to switch active role
We are considering assigning multiple roles to some users/principals in our Struts 1.1 application. The alternative is to have to give some users multiple login ids, which does not seem attractive. J2EE, Struts and Tomcat all seem to support multiple roles. BACKGROUND: I took a look at creating the logic to figure out how the various roles act when combined - its complex, but doable. But the view of data the user might see in such a situation may be confusing. My inclination is to build support for a concept of the active. User's with multiple roles could, at will, switch which role they were playing. The current active role will of course be stored in the user's session. Examples of our roles might be the following three: STDUSER - allows a user to maintain a set of data on the system that applies mostly to them. Their data will reference common data that is maintained by the organization. ORGADMIN - maintains the common/shared data that is referred to by all. HELPER - allows an expert user to view data created by others with the STDUSER role, but not update the data. They help less experience users. The roles authorize actions at two levels. 1) Standard J2EE security can use the rols to decide which actions/pages a user can switch to/see. 2) Additional business logic decides what particular subset of data the user will see, depending on their role, on a given page. The users will not need to switch roles often, and there will be a default role defined for each user. MY QUESTIONS: 1) Is this a good approach or are there better alternatives? 2) How can I put a mini form in my header that supports switching roles, but still stay on the current screen so that subsequent actions will take this new active role into account. My understanding is that only a single form can be submitted. Most of my pages have a main form, and then would have this mini form for switching active roles.

Re: Application-specific Manager access?

The manager is a servlet container application (as I gather it's called) and is in server/webapps/manager, rather than an application under webapps. How can this be associated with a particular virtual host? I've created two virtual hosts with their own appBases, and put different applications in them. I copied the webapp/ROOT contents into the appBase of each virtual host so that I'd have an opening page. That part is working. When I hit the manager/html on a virtual host, the resource is not available. What is the connection between webapps/ROOT, webapps/manager.xml, manager/html and server/webapps/manager? Thanks for your help! 2) Write a filter and add that to the manager web.xml to perform the extra acl needs 3) Write a perl(or pick your fav lang) wrapper that does all the ACL work then it calls the manager app URLS for you. -Tim Leonard Sitongia wrote: Hi!

Re: deployment quirk in Tomcat5. Bug?
Jacob Kjome wrote: When deploying war files in Tomcat-5.0.16, I noticed something a little odd. After using the ant manager deploy task and then doing an undeploy, manually dropping the war file into CATALINA_HOME/webapps trigger auto-deployment. For example, say I have myapp.war. I just drop this into Tomcat5's webapps directory and it deploys the app as expected. I can do an undeploy via the html manager interface and it undeploys as expected. I can repeat this ad- infinitum and everything works fine. Now, I deploy myapp.war via the ant manager deploy task and it deploys as expected. Then I undeploy it with the html manager interface. Now I try dropping the war file manually into webapps as explained above. This time, the war does not deploy. If I restart Tomcat5, manual deployment works fine again...until after the first time I use the ant manager deploy task, of course. I can't imagine this is expected behavior. Well, at least I didn't expect it. Can anyone else confirm what exactly expected behavior is before I report a bug on this? Don't bother: there's no use case for this, other than giving me a headache. I don't find auto deploy very useful anyway, given that Tomcat doesn't have a fancy deployer like JBoss. It works much better when used in its simple scenario (you want to deploy or update a WAR) rather than more complex stuff, when you should really use the manager. For non development stuff, forget about the auto deployer, and use exclusively the manager. BTW, for updating a WAR with the auto deployer, you don't need to undeploy first with the manager, and then copy the WAR over again: simply overwrite the WAR and the webapp will be undeployed and then redeployed. -- x Rémy Maucherat Senior Developer Consultant JBoss Group (Europe) SàRL x - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
