How to detect expired session vs. no session?
Hi, How can I tell between a request using an expired session vs a request with no session at all? I need to show different messages to users being kicked due to inactivity and to anonymous users.

RE: How to detect expired session vs. no session?
if you call request.getSession(false) this will return null if the request is not associated with a request already. the false param turns off the default behaviour of creating a new session when none exists. -Original Message- From: LAM Kwun Wa Joseph [mailto:[EMAIL PROTECTED] Sent: Wednesday 08 December 2004 08:23 To: [EMAIL PROTECTED] Subject: How to detect expired session vs. no session?

RE: Implementing Realm
Sorry if I'm being stupid, but it simply doesn't match my experiences. I'm using tomcat 4.1.30 as it is with standard MemoryRealm implementation. The username/passwords are created using the tomcat-users.xml, but If I change these without restarting tomcat the usernames and passwords are not being updated. Example: I enter a webapp with security constraints with my old password: xxx Then I change the user-role element in conf/tomcat-users.xml so that the password is now: yyy I start a new browser. In order to get a new client. Enter the new password... No entrance. Entering the old password gives a much better result though... in server.xml there is a userdatabase element, that is documented as a !-- Editable user database that can also be used by UserDatabaseRealm to authenticate users -- In the implementation (MemoryUserDatabase.java) there is no sign what so ever that it detects an update in the tomcat-users.xml file. The first method used is findUser(...) that just returns a value from a HashMap... Regards Morten At 14:50 07-12-2004, you wrote: Hi, Yeah, I'm sure.

RE : Threads issues in Tomcat 5.0.28
2. you can use kill -3 command to dump the thread stack and execute the same command few seconds later. You obtain two stack trace that you can compare to identify the potential source of inativity. -Message d'origine- De : Matt Robinson [mailto:[EMAIL PROTECTED] Envoyé : mercredi 8 décembre 2004 03:32 À : [EMAIL PROTECTED] Objet : Threads issues in Tomcat 5.0.28 Hi, We have 5 instances of Tomcat 5.0.28 running on their own high performance servers (dual XEON / 2GB RAM, etc) receiving AJP13 connector requests via our main web server which has IIS 5, IIS redirector, and Tomcat4. This works great even under high loads except for one thing: after several hours of usage (could be 3 hours or up 24 hours), the number of Tomcat threads on the 5.0.28 systems will suddenly increase at a rapid rate until Tomcat no longer responds to requests. It will hit the max # threads (which defaults to 200) and essentially freeze until it is restarted. This is strange because this behavior does not seem to correspond to increased usage of the particular server it occurs on. We are not sure what is triggering this and what those Tomcat threads are waiting on [they remain busy, waiting and unable to be reused by Tomcat]. My questions are: 1. Has anyone else experienced this kind of Thread explosion problem? 2. Is there a way to find out exactly what each Tomcat Thread is doing/waiting for? 3. Is there a way to periodically clear Tomcat's threadpool -- i.e. get rid of waiting/busy/unusued threads. We are working on ways to automatically restart Tomcat once a certain # of threads is reached, but this is not an acceptable solution, only a temporary workaround of course.

RE: How to detect expired session vs. no session? (Solved)
Confirmed that request.getSession(false)==null for both expired session
requests and anonymous requests, if I have %@ page session=false % in
my pages.
I just figured out the follow which work exactly what I wanted:
boolean hasSessionID =
(request.isRequestedSessionIdFromURL() ||
request.isRequestedSessionIdFromCookie());
if (hasSessionID !request.isRequestedSessionIdValid()) {
// expired/invalidated session
}
else {
// no session at all
}
I haven't tested this, but I *think* that a request containing an
expired session will still return a non-null session object, but a
different instance to the one that would have been returned pre-timeout.
But I don't know that for a fact. why not just test it out yourself,

Server Status and connection information
I see in the manager app that only server status information about connections to the manager app has extended information attached to it. For our production webapp the only information is that it is a Keep alive connection, and it has no metric about bytes sent or received, or what the request or vhost is. Only what the host is. How can I enable the more finegrained information for our webapp? (The connection status, what the request is, and bytes sent/received) Also, how does the manager keep track of errors? I.e. what kind of errors increments the Error coun t in the manager? I couldn't find any documentation about this part of the manager in the tomcat documentation.. Hope someone can help me. -- \ Olve S. Hansen \ mailto:[EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

the fact that eclipse starts tomcat or something... Anyways, I googled
for similar error messages, turns out that security.policy in
JAVA_HOME/jre/lib/security/security.policy has to be changed so (5432 is
postgres' port):
grant {
permission java.security.AllPermission;
permission java.net.SocketPermission 127.0.0.1:1024-, listen;
permission java.net.SocketPermission 127.0.0.1:5432, accept, connect, listen, resolve;

Now tomcat works happily with postgres.

Thread safety for RequestDispatcher
I'm looking at design options for a servlet that uses forwarding. If I were to get a RequestDispatcher in the init method (from ServletContext) and store it as a static field, it would save getting a RequestDispatcher for every request object. That may minimise unnecessary repetition, but I wonder if it is safe to have multiple request threads forwarded via the same RequestDispatcher instance? Previous mailings say that forwarding should be handled by the same thread as the request. I couldn't find any guidance here or on the Web about multiple threads accessing the same RequestDispatcher. -- URL:http://www.codestyle.org/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
OutOfMemory! Tomcat meets sudden spikes of used memory sometimes.
Hi folks, I am puzzled by the situation that Tomcat 4.1.31 meets sudden spikes of used memory sometimes. Then it will increase to throw OutOfMemory Exception and tomcat is hanging. Those memory spikes appear in my Web application for a long time. The odd thing is that it does not seem to progressively go up but rather spike up with each next full GC will clean less objects out. This is three pictures of the gc log. http://my.sme.cn/jsp/main/memoryleak.png http://my.sme.cn/jsp/main/memoryleak2.png http://my.sme.cn/jsp/main/memoryleak3.png I used HPjtune tool to watch the gc log. System using windows 2000 server, 2*CPU, 2G memory, JSDK 1.4.2_05, tomcat 4.1.31, And set -Xms1250m -Xmx1250m -server -XX:+UseParallelGC -Xloggc:D:\tomcat\logs\gc.log At first, I doubt if my app program has memory leak. But the application only runs by JSPs and javabeans.(I abandon using DBCP pool and any thread operation because of the memory leak.) I think simple JSPs can't cause the memory spike. I have a monitor.jsp to show my application status. http://my.sme.cn/jsp/main/monitor.jsp The WebSite uses normally below 100M memory heap through my monitor.jsp. It can run a few days, or a few hours before the spike appears. It is irregular. I read the access_log and want to find answer. But I can't find any clue. Then, I think tomcat 4.1.* has some bugs causing the memory leak. I upgraded my application to tomcat 5.0.18, but I met same thing. The WebSite's hits is more than 200,000 per day. I try to use OptimizeIt 6 profile to watch memory status, but OptimizeIt always exits after runs 2~3 hours. I guess this program maybe need using progressive memory of system to log things and analyze those when I notice Optimizeit used 1.6G system memory.(and OptimizeIt 6 profile only runs under tomcat 4.1.*! So I return to tomcat 4.1.31) I don't know how to cause the thing and how to find solution. Any suggestion is appreciated. Thanks.

Maybe this is because I'm using version 5.0.30 of tomcat, or 1.5.0 jdk, which might be incompatible. Is the application taglib no longer developed? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Best place to store files ?
Hi, What Wendy said is right on, so I'm glad you're already down that path. If the files are temporary, i.e. you don't mind them being erased when the server restarts, you can use the javax.servlet.context.tempdir context attribute. That's the portable, preferred way to handle temporary files. For permanent files, do what Wendy said. Tomcat is not deficient or lacking here in any way: if something is lacking, it's the Servlet Spec, but I personally don't think it's lacking because there's still a use-case for the no-filesystem servlet container.

I was just wondering whether there was a preferred method for this, and maybe a folder in the Tomcat directory for that purpose. Nothing in the Servlet Specification requires Tomcat to provide you with a permanent place to put uploaded files. My advice would be to put them outside of Tomcat, and write a thin layer to insulate the Servlet from whatever decisions you're making today. That way, if you decide at some point in the future to put the files in a database, or do something else with them, you don't have to mess with the Servlet code. Your Servlet shouldn't know or care where the files are, it should just call 'read' or 'write' and let the data access layer deal with the details. Which is what I already do. As a matter of fact, the layer I'm using makes it look like a database. The only thing I was looking for is the preferred place for storing files. If there is none, that's ok. --- Eric VERGNAUD - JLynx Software Cutting-edge technologies and services for software companies web: http://www.jlynx.com --- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

RE: OutOfMemory! Tomcat meets sudden spikes of used memory sometimes.
The fact that you have the same symptons in tomcat 4 and in 5 points towards your application as being the culprit. Is there any reason why you chose tomcat 5.0.18 instead of one of the many newer releases? I would find another profiler that works with both and try your tests again. Ta Matt -Original Message- From: Li Zhenxing [mailto:[EMAIL PROTECTED] Sent: 08 December 2004 13:47 To: [EMAIL PROTECTED] Subject: OutOfMemory! Tomcat meets sudden spikes of used memory sometimes. Hi folks, I am puzzled by the situation that Tomcat 4.1.31 meets sudden spikes of used memory sometimes. Then it will increase to throw OutOfMemory Exception and tomcat is hanging. Those memory spikes appear in my Web application for a long time. The odd thing is that it does not seem to progressively go up but rather spike up with each next full GC will clean less objects out. This is three pictures of the gc log. http://my.sme.cn/jsp/main/memoryleak.png http://my.sme.cn/jsp/main/memoryleak2.png http://my.sme.cn/jsp/main/memoryleak3.png I used HPjtune tool to watch the gc log. System using windows 2000 server, 2*CPU, 2G memory, JSDK 1.4.2_05, tomcat 4.1.31, And set -Xms1250m -Xmx1250m -server -XX:+UseParallelGC -Xloggc:D:\tomcat\logs\gc.log At first, I doubt if my app program has memory leak. But the application only runs by JSPs and javabeans.(I abandon using DBCP pool and any thread operation because of the memory leak.) I think simple JSPs can't cause the memory spike. I have a monitor.jsp to show my application status. http://my.sme.cn/jsp/main/monitor.jsp The WebSite uses normally below 100M memory heap through my monitor.jsp. It can run a few days, or a few hours before the spike appears. It is irregular. I read the access_log and want to find answer. But I can't find any clue. Then, I think tomcat 4.1.* has some bugs causing the memory leak. I upgraded my application to tomcat 5.0.18, but I met same thing. The WebSite's hits is more than 200,000 per day. I try to use OptimizeIt 6 profile to watch memory status, but OptimizeIt always exits after runs 2~3 hours. I guess this program maybe need using progressive memory of system to log things and analyze those when I notice Optimizeit used 1.6G system memory.(and OptimizeIt 6 profile only runs under tomcat 4.1.*! So I return to tomcat 4.1.31) I don't know how to cause the thing and how to find solution. Any suggestion is appreciated. Thanks.

RE: HttpServletResponse.setStatus and setContentType

Yoav Shapira http://www.yoavshapira.com -Original Message- From: Dunlop, Aaron [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 07, 2004 5:44 PM To: Tomcat Users List Subject: HttpServletResponse.setStatus and setContentType I have a standard HTTP servlet acting as an XML web service endpoint, running on an embedded Tomcat 5.0.30. I of course use HttpServletResponse.setContentType to specify that the response is text/xml. When the request is successful and I set a 2xx HTTP response code, the Content-Type header looks as expected. But if an error is detected and I return an HTTP error code (using setStatus), the Content- Type header specifies text/html;charset=utf-8 instead of text/xml. It doesn't seem to matter whether I call setContentType before or after setStatus, and all the 4xx and 5xx codes I've tried trigger this behavior. I'd just ignore it, but unfortunately, the WSI Basic Profile specifies that a SOAP fault must return a 500 along with the XML fault. And some clients (ahem... .NET...) seem to choke trying to parse the fault when the wrong content-type is returned. I didn't find anything in the specs or documentation that indicated to me that this was required behavior, but perhaps I'm missing something. Any ideas?

RE: OutOfMemory! Tomcat meets sudden spikes of used memory sometimes.
Hi, Besides what Dale said, which is true, I'd like to point out a couple of other additional things. Those memory spikes appear in my Web application for a long time. The odd When a spike appears for a long time it's not a spike: it's the steady state.

I used HPjtune tool to watch the gc log.

How can there be big jumps all over the place? At first, I doubt if my app program has memory leak. But the application only runs by JSPs and javabeans.(I abandon using DBCP pool and any thread operation because of the memory leak.) I think simple JSPs can't cause the memory spike.

RE: Thread safety for RequestDispatcher
Hi, You're right that a static request dispatcher is a negligible performance gain for a large thread-safety risk. You can obviously test it out with a client that will send multiple concurrent test requests. But if you don't have the time or desire to test it out, you can know that obtaining a request dispatcher is usually a low-latency operation in Tomcat, and therefore the performance gain is not worth the risk.

This works great even under high loads except for one thing: after several hours of usage (could be 3 hours or up 24 hours), the number of Tomcat threads on the 5.0.28 systems will suddenly increase at a rapid rate until Tomcat no longer responds to requests. It will hit the max # threads (which defaults to 200) and essentially freeze until it is restarted. This is strange because this behavior does not seem to correspond to increased usage of the particular server it occurs on. We are not sure what is triggering this and what those Tomcat threads are waiting on [they remain busy, waiting and unable to be reused by Tomcat]. My questions are: 1. Has anyone else experienced this kind of Thread explosion problem? 2. Is there a way to find out exactly what each Tomcat Thread is doing/waiting for? 3. Is there a way to periodically clear Tomcat's threadpool -- i.e. get rid of waiting/busy/unusued threads.

From: Warron French [mailto:[EMAIL PROTECTED] Yes, I do have JBoss-3.2.5 running on this server. I have also recently found out that the data is on a windows server running MSSQL. Any ideas on how to test that connectivity? One approach is to start SQL Profiler on the SQL Server box (ask a DBA if you can't get to the box yourself) and watch for connections from your JBoss server. Then run a page that you reckon makes a connection to the server. If they see a connection, it's probably working :-). If not, you'll need to know: - Your connection details to the SQL Server, especially whether you're using SSPI or username/password security; - If using SSPI, the Windows login under which the JBoss server [probably!] is running. Then you can use an appropriate diagnostic tool (ask me again!) to try to make a connection to the database. Are you running JBoss on Windows or UNIX? - Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Multiple domains on single machine
You may not even need to use the Apache HTTPD web server, in which case
you should just have Tomcat listen on port 80 itself, and refer to the
documentation for Hosts on the Tomcat site.
If you really need to use the Apache web server, you'd probably get
better advice from the HTTPD list for your Apache configuration. So
this is a bit off topic, but it's a problem that you have the one named
VirtualHost (the default one, *:80), and two configurations for it. You
need to have two named VirtualHosts (one for each of your virtual hosts,
eh?). Read the Apache HTTPD documentation at
http://httpd.apache.org/docs-project/. There's very good documentation
on most of the directives. When you get that sorted, you'll need to
bring Tomcat up behind Apache. This has been worked out far better in
numerous how-tos and messages to this list than I could here. You'll
find some helpful links at
http://wiki.apache.org/jakarta-tomcat/UsefulLinks.

RE: How to detect expired session vs. no session? (Solved)
I'm a bit puzzled. There is something not quite right here (or maybe I'm
not quite understanding correctly). Aren't sessions created as soon as a
JSP within a ServletContext is accessed, irrespective of whether the user
authenticates or not? Thus invalid sessions vs anonymous sessions is not an
either/or choice - a session can be both valid and authenticated, or both
valid and anonymous. Is invalid the same as expired?
Also there seems to be a slight contradiction in what you say below, because
if request.getSession returns null for an invalidated session, how can you
then call isRequestedSessionIdValid() on an invalidated session without
getting a NullPointerException? I realise that the method is not called on
the session object directly, but surely it must access the session object at
least indirectly?

Subject: RE: How to detect expired session vs. no session? (Solved)
Confirmed that request.getSession(false)==null for both
expired session
requests and anonymous requests, if I have %@ page
session=false % in
my pages.
I just figured out the follow which work exactly what I wanted:
boolean hasSessionID =
(request.isRequestedSessionIdFromURL() ||
request.isRequestedSessionIdFromCookie());
if (hasSessionID !request.isRequestedSessionIdValid()) {
// expired/invalidated session
}
else {
// no session at all
}
I haven't tested this, but I *think* that a request containing an
expired session will still return a non-null session object, but a
different instance to the one that would have been returned
pre-timeout.
But I don't know that for a fact. why not just test it
out yourself,
it's not that hard, just shorten the timeout interval first
so that you
don't have to wait 30 mins to do your test ;)

But does it have the same effect for a request with an
expired session vs
a request with no session at all? I think it will return
null in both
cases.
if you call request.getSession(false) this will return
null if the
request is not associated with a request already. the
false param
turns off the default behaviour of creating a new session when none
exists.

RE: HttpServletResponse.setStatus and setContentType
Thanks for the suggestion, Yoav, but thus far in my experiments, sendError seems to --Send Content-Type: text/html;charset=utf-8 --Ignore the content I've written (using ServletResponse.getOutputStream()) and instead send the generic Tomcat HTML 'Server Error' message. Which of course is even worse for a web service client, since it's not well-formed XML ;-) I'm trying: servletResponse.setContentType(text/xml); ... soapResponse.save(servletResponse.getOutputStream()); servletResponse.sendError(500); (where soapResponse.save writes the XML to the specified OutputStream) Using sendError(int, String) does effectively the same thing, except with the string message included in the HTML response. When I instead tried: servletResponse.setContentType(text/xml); ... servletResponse.setStatus(500); soapResponse.save(servletResponse.getOutputStream()); I got the appropriate XML contents back, but with Content-Type set to text/html;charset=utf-8 instead of text/xml There must be a way to do this - plenty of people use Tomcat to handle SOAP web services...I'll check the Axis source and see how they handle it.

But if an error is detected and I return an HTTP error code (using setStatus), the Content- Type header specifies text/html;charset=utf-8 instead of text/xml. It doesn't seem to matter whether I call setContentType before or after setStatus, and all the 4xx and 5xx codes I've tried trigger this behavior. I'd just ignore it, but unfortunately, the WSI Basic Profile specifies that a SOAP fault must return a 500 along with the XML fault. And some clients (ahem... .NET...) seem to choke trying to parse the fault when the wrong content-type is returned. I didn't find anything in the specs or documentation that indicated to me that this was required behavior, but perhaps I'm missing something. Any ideas?

what to do about port for Tomcat 4 on Linux?
I want to move to Tomcat 5 right now, but can't yet, and for the time being we need to move from Tomcat 4.1.23 on Windows to 4.1.31 on Red Hat, so I'm now facing a question of what to do about the port Tomcat runs on. I've read stuff online that suggests it's best to leave it at 8080 since 80 is a privileged port on *nix. But from that point, I'm not sure what the best practice would be, though I've read different options, like user space port forwarding, kernal space port forwarding, or using a port forwarder (portfwd or redir4a), none of which I'm familiar with. What do you Tomcat users suggest would be a good approach for someone who's only a beginner/intermediate with Linux and using standalone Tomcat? In case it matters, note that we are also moving from our single Windows web server to 2 Linux web servers (each running standalone Tomcat), and we're trying to configure a load balancer hardware appliance in front of the two web servers.

I suspect that the 1.4 exam tries to test for deeper understanding. My second suspicion is that underneath all the childlike facade of this Head First book that the authors are trying to make a deeper understanding of how servlets, jsp, etc. work more important than memorizing the spec. But I can't say whether I think that they've been successful until I finish the book. It may be when I'm done I'll just find that I didn't the childish style never added up to anything.

RE: Possible to Authenticate from Servlet/Webapp Code?
Thanks for the info Yoav; however, I've tried what you suggested, and
everything I can think of myself, and no luck.
I don't know of anything in the declarative security that would help with
this. Most of my apps use the standard for security, but there's one app
that uses it's own login from a database. I created my own Realm that uses
its table structure, thinking that in the login of this app, I could simply
get a reference to the Realm, pass the credentials to it and bingo, I'm
authenticated in both.
I have tried:
1. Navigating the tomcat class hierarchy: problem is with class loaders.
When I'm in the webapp and I do ServerFactory.getServer(), there are no
services configured (ie ServerFactory.getServer().findServices() returns an
empty array.
2. Placing my custom Realm in the common/lib, so it would be available to
all classes. Then the catalina classes (which I extend, particularly
JdbcRealm) aren't visible causing ClassNotFoundExceptions on startup.
There's no way to break out of these dependencies that I can see.
3. Binding the Realm into JNDI from within the Realm constructor. Doesn't
seem to work, getting javax.naming.NameNotFoundException: Name java:comp is
not bound in this Context. Because the Realm is created first off, I don't
think the JNDI contexts are set up.
Is there some way I could do it through the MBeans maybe?
Any other ideas, or even explanations of why I'm bone-headed are
appreciated! :)

Hi,
The Spec-mandated, and therefore portable, approach is via the web.xml
declarative security.
The Tomcat-specific way would mean you navigate down the container
hierarchy, starting with ServerFactory.getServer, down to Service,
Engine, Host, to find your Realm object. You could probably do this
once on your app startup, e.g. in a listener or filter init.

Question:
-
Is there a way to authenticate a user to the container (including SSO)
from
within a servlet? Something like:
protected void service(HttpServletRequest req, HttpServletResponse
resp) {
Realm tomcatRealm = //how to get the realm???
tomcatRealm.authenticate(dauser, dauserspassword);

}

---
I know how to configure the custom login pages, etc., but I need a way
to
authenticate in two places at once, due to a legacy application.
It seems like this should be easy to do, so I expect I'm missing
something
obvious, but I simply can't figure out how to do it. I've been
searching
for
a while...
While standards-based would be better, a Tomcat-specific way would be
fine
as well.

deleteOnExit() doesn't work in Tomcat on temp files
I've run into a bug that I only experience in Tomcat. If, within a
servlet, I create a temporary
file using File.createTempFile(...), Tomcat puts the file in its temp
directory, which is fine. However,
if I call deleteOnExit() on the file, the file doesn't get deleted when
Tomcat is shut down. This happens
even when the temporary is never opened.
I am using Tomcat 5.5 on WindowsXP. Tomcat is installed as a
service, and I am stopped and restarting it using the monitor
program. I also tried rebooting my machine (to make sure Java had
exited) but the files were still there.
Has anyone else run into this? Is there a workaround?
Thanks,

p.s. Here's my test servlet's code:
// TempFileTest
import java.util.*;
import java.io.*;
import javax.servlet.http.*;
/**
* This class is a servlet used to test the problem with
File.deleteOnExit()
*/
public class TempFileTest extends HttpServlet {
/**
* This method should be called automatically when the servlet is
* initialized.
*/
public void init() {
try {
File f = File.createTempFile(TEMP_FILE_TEST, null);
f.deleteOnExit();
}
catch (Exception e) {
System.out.println(TempFileTest could not create the temp
file!);
e.printStackTrace();
}
} // init

Now you have to turn on security in Tomcat. If you want to talk to the AD for this purpose, well, lots of luck. You will need a custom realm or to implement this by hand in your servlets. Once you have security enabled at all, the browser (on Linux or wherever) will pop up a 'basic auth' dialog, and the user can type in a domain-qualified name.

This works great even under high loads except for one thing: after several hours of usage (could be 3 hours or up 24 hours), the number of Tomcat threads on the 5.0.28 systems will suddenly increase at a rapid rate until Tomcat no longer responds to requests. It will hit the max # threads (which defaults to 200) and essentially freeze until it is restarted. This is strange because this behavior does not seem to correspond to increased usage of the particular server it occurs on. We are not sure what is triggering this and what those Tomcat threads are waiting on [they remain busy, waiting and unable to be reused by Tomcat]. My questions are: 1. Has anyone else experienced this kind of Thread explosion problem? 2. Is there a way to find out exactly what each Tomcat Thread is doing/waiting for? 3. Is there a way to periodically clear Tomcat's threadpool -- i.e. get rid of waiting/busy/unusued threads. We are working on ways to automatically restart Tomcat once a certain # of threads is reached, but this is not an acceptable solution, only a temporary workaround of course.

directory for compiled JSPs
Sorry if this has been asked before. I searched archive but couldn't find exactly what I'm looking for. The issue happened is that when using Tomcat5 and deploying web applications with same context root (path), the second web app deployed (and Tomcat restarted) will still have browser pointing to the main JSP of the first application (assuming they have the same starting JSP page). What I noticed then is from Tomcat 4 to Tomcat 5, it seems the working directory structure has changed when JSPs are compiled which may have contributed to this. - in Tomcat 4, I used to get under host something like D_3A_5Ctemp_5Ctest_5Cwebcontext (docBase), and below it the web context if any. - in Tomcat 5, it directly puts web context directory under host. I'm wondering if I could/should bring this old feature of Tomcat 4 back. What are the reason(s) that this is changed (e.g. consistency, JspC, etc.)?

DO NOT EVER use deleteOnExit(). Especially not in something like a web app, which has an indeterminate but generally long lifetime. Consider the API removed from Java. Period.

(B) it cleans up during runtime, rather than whenever the JVM should happen to exit cleanly through the right path.

How to start multiple Tomcats
Hi, Sorry this might be a newbie question, I'm an intern and I have no idea what's going on here. We are trying to setup an automated J-Unit test from Ant using Cruise Control where we need multiple copies of tomcat servers running (by supplying different server.xml files). I tried using the org.apache.catalina.startup.Bootstrap class to start the tomcat servers, but they don't seem to accept an argument to take different server.xml files. Then I tried using org.apache.catalina.startup.Catalina class, which does take a -config option to specify a different server.xml file, but it doesn't return until a shutdown is called, so the process just sits there and I cannot execute my next commands. Is there something I'm missing, any suggestions? Thanks in advance. __ Robert Lin Eng. Intern | Blue Jungle | Redwood City, CA [EMAIL PROTECTED] mailto:[EMAIL PROTECTED]

[ANNOUNCE] JSP 2.1 and Faces 1.2 Early Draft Review
We're pleased to announce the availability of the Early Draft Review of the next versions of the specification for JavaServer Pages and Faces. JavaServer Pages (JSP) 2.1 is developed under JSR-245 and JavaServer Faces (Faces) 1.2 is developed under JSR-252. The two expert groups are working together to improve the alignment between these two powerful web presentation technologies. The foremost such alignment issue is the Expression Language, as stated in both JSRs. JSP 2.1 exports the Expression Language (EL) into its own separate document; technically a sub-document of the JSP specification. The Unified EL spec defines a new top level java package, javax.el. This package is completely independent of the technology using it and allows the using technology to plug itself into the EL resolution process. The bulk of the changes in the JSP spec itself follow from how it uses the Unified EL. As mentioned in the original JSR-252, this spec is not a new feature release. Faces 1.2 contains the work for it to leverage the new Unified EL, as well as a few spec related bug fixes. The alignment of Faces and JSP in these JSRs enables some new capabilities and provides a solid foundation for future growth. For example, in a web application that uses both Faces and JSP, it is possible for pages that only use JSP (without any faces content) to access managed beans. Please see Appendix E of the JSP spec and the preface of the Faces spec to see details of what's changed! To access the specifications: JSP 2.1 EDR (JSR-245) http://jcp.org/aboutJava/communityprocess/edr/jsr245/ Faces 1.2 EDR (JSR-252) http://jcp.org/aboutJava/communityprocess/edr/jsr252/ Sincerely, Ed Burns, Pierre Delisle, Roger Kitain, Mark Roth and the JSR-245 and JSR-252 Expert Groups. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: How to detect expired session vs. no session? (Solved)
Following my comments below I thought I'd follow up a bit with some brief
testing of my own.
This is what I think it going on. Someone with more knowledge/experience,
please correct me if anything I say here is wrong. I'm assuming that the
browser is cooperating with sessions OK, i.e. not configured to block them.
When TC receives a request, it checks to see whether the browser has
included a jsessionid in the request. You can do this yourself as follows:
String sessId = request.getRequestedSessionId();
If there is a jsessionid in the request (i.e. null != sessId), and it
matches a valid TC session object (i.e. one that has not timed out or had
invalidate() called on it), that session object is associated with the
request, and the same jsessionid will be written back to the browser with
the response that TC sends back, so that the session is persisted.
If the requested jsessionid does not match a valid session, a new session is
immediately created by TC and assigned to the request, with a new
jsessionid, which TC writes back to the browser with its response. This new
session creation seems to take place before the doPost() method is entered.
However you can still tell whether an old jsessionid was requested even
after the new jsessionid has been assigned, as follows:
String id = request.getRequestedSessionId();
if (null==id)
{
// there was no jsessionid in the request
}
else if (request.isRequestedSessionIdValid())
{
// there was a valid jsessionid in the request
}
else
{
// there was an invalid jsessionid in the request
}
In either case, a session object is always returned by request.getSession()
and request.getSession(false). (Actually this was a surprise to me, because
it seems that it is not possible to suppress creation of a new session where
none exists by using getSession(false)?)
Thus, the effect of all this taken together is that browser sends a
jsessionid to TC with every request except when the browser is opened afresh
and makes its first request to the webapp. It even seems to send timed out
jsessionids to the server when the browser has been left open for longer
than the session timeout (presumably TC handles expiry issues server-side),
or when the browser is left open while TC is restarted. Once TC has sent a
jsessionid to the browser, the browser will keep returning it in every
request to TC until the browser is closed, or TC changes the jsessionid for
some reason.
Now, the question of authentication. I don't think that there is way to
tell that a user has authenticated using any of the code that Joseph or I
have mentioned, because this code deals only with sessions (which exist
whether you authenticate or not). The code above merely tells you
information about a browser's recent visit to the site. I'm not familiar
with TC's own authentication, but in my own case, successful authentication
is indicated by adding an object to the session to indicate that a given
authenticated user is using it. Thus I use a test like:
if (null==(myclasses.User)request.getSession().getAttribute(CURRENT_USER))
{
throw new MyAuthException(User not authenticated);
}
else
{
// complete their request
}
Calling the invalidate() method on a session seems to cause the session
object to be destroyed immediately. If this is done during processing of a
request, I think that TC still sends the old jsessionid to the browser in
the response. So the next time that the browser makes a request, it will
present the old jsession, which will be invalid, so TC will replace the
jsessionid at that point.
Hope this is useful to someone else and isn't too far off the mark...?

Subject: RE: How to detect expired session vs. no session? (Solved)
I'm a bit puzzled. There is something not quite right here
(or maybe I'm
not quite understanding correctly). Aren't sessions created
as soon as a
JSP within a ServletContext is accessed, irrespective of
whether the user
authenticates or not? Thus invalid sessions vs anonymous
sessions is not an
either/or choice - a session can be both valid and
authenticated, or both
valid and anonymous. Is invalid the same as expired?
Also there seems to be a slight contradiction in what you say
below, because
if request.getSession returns null for an invalidated
session, how can you
then call isRequestedSessionIdValid() on an invalidated
session without
getting a NullPointerException? I realise that the method is
not called on
the session object directly, but surely it must access the
session object at
least indirectly?

Please don't jump to determine it's a memory leak just because more memory is used. I think it is a obvious memory leak because the number of request threads doesn't increase and the app hits just is normal when the inflexion of gc figure appreas. The question only is caused by my app, or tomcat. So you're setting the heap size to a constant 1250MB. How can there be big jumps all over the place? It should been given max memory as possible to avoid JVM increases heap progressively when the server machine only runs tomcat. I think all heavy load app should set two parameter equal. I bet your app is more likely than Tomcat to have a leak ;) Simple JSPs can cause memory spikes, as can simple servlets. DBCP and threads do NOT necessarily cause increased memory usage. It is probably that my app has a leak. I agree. But every JSP has been visited during four days of system in order. Why to appear spike at fifth day? I have 2~3 hundreds JSPs that almost be requested everyday. Does one JSP has memory leak at a special situation? Or one JSP running at a special situation causes tomcat leak? Get a test system, put your app on it, run it with a profiler, and simulate load using a test tool of your choice, e.g. JMeter, ab, wget, grinder, whatever. Then see where memory is retained during your spikes. Thanks for the advice. and thanks for Dale's suggustion. I will try to profile heap through -Xrunhprof and other tools.

Apache 2.0 + Tomcat 5.5.4 scalability
Dear Tomcat users, I'm a new tomcat user evaluating it for FreeBSD5.2. I'm trying to ascertain how well Tomcat will scale from 1- to 2- and 4-proc BSD machines. The only problem is, no matter how I configure workers.properties and server.xml, I get about the same RPS and TTLB for all setups, despite adding workers. I'm using mod_jk (JK-connector-1.2.6) with Apache 2.0. One Tomcat installation uses 8001 as its primary port, the other 9009, and I run startup.sh and both, spawning 2 times 46 = 92 java processes.

Re: [OT] Re: Tomcat mailing list is full of non tomcat topics
Personally, it seems like truly off-topic messages get tagged pretty quickly on this list. I think that's a reasonable solution to handle this problem. As for the *root* of the problem, the VAST majority of questions come from novice users who, predictably, don't know the difference between a Tomcat question and Servlet/JSP question. For most people, there *is* no difference. From that standpoint, it's artificial to say that some questions are Tomcat ones and others aren't -- they are all Tomcat-related and, as such, I feel like this is an appropriate place to address them. IMHO, asking a novice user to take it elsewhere would be a fairly cruel thing to do to an already confused and potentially frustrated user. That said, lengthly threads that banter about the merits of various JSRs and specs clearly don't belong here and should either be relocated or (more likely), marked OT. justin At 06:56 PM 12/8/2004, you wrote: On Wed, 2004-12-08 at 17:41, Roberto Cosenza wrote: I'm not talking about moderating but about informing the users that this is not the right place.

That said, lengthly threads that banter about the merits of various JSRs and specs clearly don't belong here and should either be relocated or (more likely), marked OT. Where Tomcat is used as the reference implementation for the Servlet and JSP specs, and where the mission of the Tomcat development team is to deliver a 100% spec compliant Servlet/JSP container, I think it would be pretty difficult to make a case for calling such discussions off-topic. Another good reason for quoting the specs, chapter and verse, is that the tomcat documentation, for the most part, doesn't repeat what's in them. Therefore, the best place to look, when you want to find out why Tomcat (or any other spec compliant container for that matter) behaves the way it does, is the specs.

And then there are the cases that would be deemed OT only to end up as a full blown Tomcat discussion. Some guy asked a question about IIS and at first it's OT. But after a few exchanges the solution is Tomcat. So even if the person is OT sometimes the answer is Tomcat.

Re: Multiple domains on single machine
Hi,
I have to use APACHE.
I have seen one example given in the APACHE documentation:
--
NameVirtualHost *
VirtualHost *
ServerName www.domain.tld
DocumentRoot /www/domain
/VirtualHost
VirtualHost *
ServerName www.otherdomain.tld
DocumentRoot /www/otherdomain
/VirtualHost
--
So may be this isnt wrong. When I add an index.html, it is displayed by
apache. But the JSP and servlet requests are not being passed to TOMCAT. In
my tomcat server.xml I have added the lines:
Host Name=support
Context path= docBase=E:/support1.cp.net debug=0
reloadable=true /
/Host
Host Name=admin
Context path= docBase=E:/admin.support.cp.net debug=0
reloadable=true /
/Host
The support one is being executed properly, but the admin one is not
being recognised. any solutions ?

You may not even need to use the Apache HTTPD web server, in which case
you should just have Tomcat listen on port 80 itself, and refer to the
documentation for Hosts on the Tomcat site.
If you really need to use the Apache web server, you'd probably get
better advice from the HTTPD list for your Apache configuration. So
this is a bit off topic, but it's a problem that you have the one named
VirtualHost (the default one, *:80), and two configurations for it. You
need to have two named VirtualHosts (one for each of your virtual hosts,
eh?). Read the Apache HTTPD documentation at
http://httpd.apache.org/docs-project/. There's very good documentation
on most of the directives. When you get that sorted, you'll need to
bring Tomcat up behind Apache. This has been worked out far better in
numerous how-tos and messages to this list than I could here. You'll
find some helpful links at
