Tomcat FAQ/Article
Hi, I would like to propose an update, patch-up and configuration FAQ/Article for beginners who have installed Tomcat. It would be great to know what needs to be done after the server has been installed to ensure that it run optimumly. Or has such a document been made available already? I'm not sure...but please do enlighten me. regards, Cheong Takhoe
Tomcat Performance
Hi, I'm encountering performance issues with regards to Tomcat. I have two servers running. One with Tomcat 3.1 and one with Tomcat 3.2, both on Window NT 4.0 . After running for a certain time, its gets slower and in the end, the web-applications can run anymore. I would like to know if any of you encountered such problem and how you worked to solve it. Urgent. Please help. regards, Cheong Takhoe
Concurrent Users - How to see it
Hi, As we need to know how many concurrent users we have on our Tomcat, I would like to know how and what tools do you folks out there use to determine the number of concurrently connect users at the moment? Thanks regards, Cheong Takhoe

RE: Common (or combined) log format from a servlet/JSP?
It does produce the apache combined format in the access.log however.. tomcat 4 must use an extened combined ( commonly irregular ) format, a superset. awstats.sourceforge.net is a perl stats package, it doesnt like this extended format but it is open source so we can change it. sorry i know this isn't really an answer but i've often found questions are usually just as ambiguous as their reply =) -Original Message- From: Gary Lawrence Murphy [mailto:[EMAIL PROTECTED]] Sent: Thursday, 17 May 2001 4:33 AM To: [EMAIL PROTECTED] Subject: Common (or combined) log format from a servlet/JSP?

This topic has been discussed several times. The reasons you mention can be adressed by a proper organisation of the mail client: - Most clients are able to show the messages by thread. - Most clients are able to filter the messages in a way that all tomcat messages go in a separate folder. - Most clients are able to delete messages with a given age.

If you found the region and can't see the error, try to
reduce the page to the bare minimum that reproduces the

I have seen a similar problem which I posted to tomcat dev. The
generated source code is
...
} finally {
if (out != null) out.flush();
if (_jspxFactory != null)
_jspxFactory.releasePageContext(pageContext);
}
...
and the error came from the releasePageContext method which tried to do
something with pageContext. It seems quite repeatable if tomcat is run
with security. e.g. standard 3.2 examples/numguess. My case is when I
have access controls turned on and am doing authentication. No answer
in the dev list. This always occurs if you have no permissions when
compiling the login page which is the result of a redirection from the
protected resource. This is in 3.2.2b4
Seems to be a general problem when run with security.

Bug in runtime/JspFactoryImpl.java
Hi,
Excuse the cross post to User/Dev but this problem has been reported by
others in user.
Further to yesterday's message re jasper/tomcat exceptions, it seems
that there is either a bug in the coed generation or the
JspFactoryImpl. If the generated code gets an exception pageContext is
never set so in the finally clause the releasePageContext will be passed
null.
Seems to me the releasePageContext should either check for null or the
generated code should check for null. In the generated number guess
code from the examples there is
---
} catch (Exception ex) {
if (out != null out.getBufferSize() != 0)
out.clearBuffer();
if (pageContext != null)
pageContext.handlePageException(ex);
} finally {
if (out != null) out.flush();
if (_jspxFactory != null)
_jspxFactory.releasePageContext(pageContext);
}
---
the exception checks for null but not the finally.
Who might be the best person to decide where the fix should go??
This causes big problems if security is turned on because any access
control failure makes this problem occur.

Difficulties with Virtual hosts
I have followed the examples in the mod_jk documentation, but can not seem to make any headway. The tomcat logs indicate the host contexts are being loaded but tomcat can not find any of the files. I have docBase set correctly, and it is outside the tomcat directory. I am at a loss as to what to try next. Glen. -- Glen Eustace, GodZone Internet Services, a div. of AGRE Enterprises Ltd., P.O.

servlet chaining, session null
Hi, i'm trying to use Servlet chaining with three servlets. In the first one i create a cession (if it doesn't exist), in the second one i put some attributes in the cession. But when i arrive in the third servlet, my session is null? As anybody already had this problem ? Is it possible to get the path of the servlet who called the last one ? I mean if i am in the ith servlet, how can i get the path of the (i-1)th servlet ?
Fwd: Re: Install Tomcat on Wíndows 95
Hi again, maybe but if if I have a slight look at my configuration I'm very shure that Tomcat works with JAVA_HOME pointing to c:\jdk1.3\bin ... It's because when Tomcat start, it looks for the java executables, and if it can find it in the path, then build the JAVA_HOME from this location instead of using yours... So if your PATH points to the JDK/bin directory, your JAVA_HOME won't be used. So you can even suppress it. Anyway, RTFM (tomcat_ug.html): Set the environment variable JAVA_HOME to point to the root directory of your JDK hierarchy, then add the Java interpreter to your PATH environment variable. Benoit

Post messages Through one interface. One could use the local mail client for both, but this means storing N thousand messages in one's local area to address 1 above, which is certainly not practical. To me, a web-based forum (eg egroups, but with a searchable archive) is best. The best alternative I can think of is to use my mail client to post messages, binning all uncoming messages from tomcat-user to TRASH, and read messages via Philip Mikal's archive at http://mikal.org/interests/java/tomcat/index.jsp (thanks Philip), but this means reading/posting via two different interfaces, so isn't entirely convenient. I'm aware that jGuru have an online forum for tomcat, but this doesn't seem to be the 'official' forum, and is certainly not as heavily used is this mailing list. But perhaps the tomcat team could make that the official one. I see what you're saying, but, ughhh, please, no web-based forums. They are not good for high-volume, everyday reading. The interface is clunky, interactivity is poor, they're slow, and they can be unreliable (much of this having to do with the fact that it's done via HTTP). I'd probably no longer participate if it were moved to a web-based forum (of course, some might consider that a good thing :-). As to the previous poster's comments, I think he's wrong on several points. For one thing, I've been on this list several months, and I don't recall seeing this topic discussed at all, let alone several times. Further, I think he's off as to the capabilities of modern mail readers -- particularly, I think there are many good, modern mail readers that don't have the first and third features he mentions. I do think the volume on this newsgroup is a problem (things are mostly relevant, but the volume is awful high), but I'm not sure what the best solution is.

The reasons you mention can be adressed by a proper organisation of the mail client: - Most clients are able to show the messages by thread. - Most clients are able to filter the messages in a way that all tomcat messages go in a separate folder. - Most clients are able to delete messages with a given age.

RE: Static filed reference BUG since( Tomcat 4b2-b5)
Just a thought - have you imported that class? You need to remember that all generated classes are placed into a package corresponding to their location in the webapp (prefixed by jsp, I believe), so classes that aren't in any package aren't in the same package as the JSP file. I believe that if you import the class (and I think you'll have to do each separate class explicitly) this should solve your problem.

RE: Cookies
(I'm not sure what this question has to do with cookies,...) I use JDBCRealm and I'd like to have the connection times out after a certain period of time. Currently, it seems that once you have logged in, as long as you don't exit from your browser, the servlets can be run forever. Is there anything I can set in server.xml? What exactly are you trying to time out--JDBCRealm's database connection, or the servlet session, or the authenticated account? (Your mention of JDBCRealm confuses me,...) 1) The database connection won't be closed until some error occurs. 2) The servlet session has a time-out specified by webapp/session-config/session-timeout in your web.xml file. 3) Authentication, I believe, is maintained by the browser, not the server, and there's no way to tell the browser to discard its credentials. Assuming you're only worried about access to your servlets (not static files on your system), you could always use your own authentication (e.g., a login form with the credentials stored as a session attribute) and bypass the browser's authentication. -- Bill K.

question about configuring tomcat with apache
Is there any way to configure tomcat so that it opens the apache web server instead of the other way around? The reason I ask is that for security reasons we would like to put the apache web server on one NT and have tomcat run on another with a firewall between the 2. It would be more secure if we could have the tomcat server open the apache web server (through the firewall) than the other way around. Is there a way to do this?

RE: servlet chaining, session null
Well, all my servlets are on the same webapps. I don't use the url rewriting, but the HttpSession. for example in the first servlet: HttpSession session = request.getSession(false); if (session == null) session = request.getSession(true); session.setAttribute(path1,request.getServletPath()); RequestDispatcher dispatch = this.getServletContext().getRequestDispatcher(/servlet/chaining.Servlet2); dispatch.forward(request,response); in Servlet2 HttpSession session = request.getSession(false); session.setAttribute(path2,request.getServletPath()); RequestDispatcher dispatch = this.getServletContext().getRequestDispatcher(/servlet/chaining.Servlet3); dispatch.forward(request,response); I do the same in the third servlet, but when i test my session, it's null.

RE: Static filed reference BUG since( Tomcat 4b2-b5)
There is a difference between adding to the classpath and importing. The class path helps the JVM find the .class file for a particular class. The import statements allow a developer to use the short class-only name (i.e. Vector) instead of the fully qualified class name (i.e. java.util.Vector). These are two entirely different concepts and one really has not bearing on the other.

starting tomcat in debug VM
Hi, I'm trying to start tomcat in debug mode using these options: TOMCAT_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n as I understand it, the address to which the debuger should connect should be displayed on stdout. However, all that is being displayed is the agent password. Any ideas what (if any) other parameters need to be passed to java in order to obtain the port that the vm is waiting for?

But to be fair, the latter two threads were before I joined this group, and the first (the most recent one) -- which consisted basically of one person saying Is there a newsgroup form of this list and another one saying Arhhh -- no way -- hardly constitutes a discussion or a thread :-). As to a mailing list vs. a newsgroup vs. a web forum: I have a strong dislike of the latter (for reasons I already mentioned); I can see legitimate and significant pros and cons of the first two, and so hence don't have a strong opinion one way or another on it. (If I couldn't take tomcat-user as a mailing list, I'd simply unsubscribe and read the archives -- and if it doesn't restrict posting to subscribers, then there's nothing really lost there -- and even if it does, perhaps there's a subscribe but no mail option.) Further, regarding a newsgroup, there's nothing stopping someone from simply going ahead and setting one up. It wouldn't be so easy to create such a Big 8 newsgroup -- you've got to go through the whole RFD/CFV process -- but, if things haven't changed too much, creating an alt group is easy. That could be a good thing, as those of the tomcat-user people who prefer newsgroups would go there, and those that prefer mailing lists would stay here -- and each would have less volume. -Ursprüngliche Nachricht- Von: Milt Epstein [mailto:[EMAIL PROTECTED]] Gesendet: Donnerstag, 17.

For one thing, I've been on this list several months, and I don't recall seeing this topic discussed at all, let alone several times. snip/ Further, I think he's off as to the capabilities of modern mail readers -- particularly, I think there are many good, modern mail readers that don't have the first and third features he mentions.
