Re: Tomcat 3.3: ThreadPool bug (IS IT SAFE FOR PRODUCTION USE???)
Are you using Tomcat standalone or with Apache? If standalone, then yes, I
would recommend using the latest version of Tomcat 4.x. If you're using
Apache, I would stick with 3.3 until the mod_jk code is fully implemented
with the 4.x versions.
Thanks,

Subject: Tomcat 3.3: ThreadPool bug (IS IT SAFE FOR PRODUCTION USE???)
Hi there,
I am trying to deploy our production service on the Tomcat 3.3 platform
(Solaris8, JDK 1.3.1) but am very often facing the instability problems.
Somehow, the ThreadPool just runs out of steam and blocks Connectors from
receiving any more requests.
Looking into the source code, I have noticed some very interesting
constructions in the ThreadPool class. Namely, the setters for the
maxThreads, maxSpareThreads and minSpareThreads are having very little
influence as the start() method is resseting the values to the default
constants ?!?!
public ThreadPool() {
maxThreads = MAX_THREADS;
maxSpareThreads = MAX_SPARE_THREADS;
minSpareThreads = MIN_SPARE_THREADS;
currentThreadCount = 0;
currentThreadsBusy = 0;
stopThePool = false;
}
public synchronized void start() {
stopThePool=false;
currentThreadCount = 0;
currentThreadsBusy = 0;
maxThreads = MAX_THREADS;
maxSpareThreads = MAX_SPARE_THREADS;
minSpareThreads = MIN_SPARE_THREADS;
adjustLimits();
openThreads(minSpareThreads);
monitor = new MonitorRunnable(this);
}
Also, the situation when there are no more available Threads in the pool
is being handled in a special way which JUST BLOCKS IN THE INFINITE LOOP :
-(((
Is the code of the Tomcat4 equaly immature or there is a fair chance to
role a productiv system on top of it?
Thanks in advance for any comments

Re: Stability of Tomcat 3.3 vs. 4.0

Re: Ever increasing heap size with Tomcat 3.2.3 !!!
I believe you need to supply the '-server' switch at startup to the JVM to be in server mode. Try dropping that switch, if you're using it. Personally, I recommend you check out the IBM JDK, too.

The standard response these people receive is to increase the heap size via -Xmx But that seems like a band-aid rather than a real solution. That just delays the inevitable. The problem is always that they are holding onto memory that they don't realize they are holding on to, or are expecting to be garbage collected but can't for whatever reason. Here are some suggestions on where to look: 1. Don't use class variables in servlets or JSPs 2. Be careful with sessions. Setting the inactive timeout to nothing allows the sessions to stay around until the server is reset, and sessions last for some time after the last request 3. Understand that it anything has a reference to an object (list, map, array) then it can't be garbage collected 4.

Re: How to Increasing Tomcat memory?
Hi Jack, You should use the TOMCAT_OPTS environment variable to set these options. So, create an environment variable called TOMCAT_OPTS and set it equal to the following: -Xms32M -Xmx64M This will set the initial size of the JVM heap to 32MB and the max size to 64MB. Replace these values with whatever you require and you're all set. The startup script for Tomcat looks for the TOMCAT_OPTS env. variable and automatically appends it's contents to the command line when starting the JVM. I recommend that you upgrade to at least version 3.2.4, due to security bugs that have been fixed in 3.2.1 and 3.2.2. None of your configuration files need to be changed. Just swap out the jar files in your TOMCAT_HOME/lib directory with the new ones.

Hi Brandon, I recommend that you use the mod_jk from the 3.3 distribution. I'm not sure if all the bug fixes have been back-ported to the 3.2.x version. Also, the 3.3 version lets you restart Tomcat without having to restart Apache. Anyway, download the 3.3 bundle (jakarta-tomcat-3.3-src.tar.gz) from: http://jakarta.apache.org/builds/jakarta-tomcat/release/v3.3/src/ gunzip and untar it and then cd to the src/native/mod_jk/apache1.3 directory.

Re: Unable to include *.sum files (Again)
Hi Jonathon, Well, obviously, I agree with you. I think the most interesting point you bring up is the fact that %@ include...% works with any file extension, whether or not it has a registered MIME type. Why should jsp:include.../ add additional restrictions? I understand the difference between the two -- page translation time vs. request time -- but don't understand why they act differently. I've gone through the JSP spec for both of them and can find nothing that requires the MIME type of the included file to be a registered text/* type.

Re: Unable to include *.sum files (Again)
We're going an awfully long way here to solve what could be cleanly done
with a simple:
jsp:include page=relativeURL flush=true /
Don't you think? All the container has to do is default the MIME type for
unknown extensions to text/html. Remember this is a JSP -- a scripting
language which was originally designed to simplify life for web designers
and other non-programmers. Having to open every included file manually with
java code defeats that purpose.

Re: Unable to include *.sum files (Again)
I'm not so sure. The JSP spec doesn't say anything about having to register the MIME type of a file before using it in a jsp:include directive. Consider how difficult that would be if you were generating dynamic filenames with extensions like .001, .002, .003, etc... You could potentially have to register several hundred (even thousand) meaningless MIME types. Also, think about what webservers do when they encounter an unknown MIME type -- they default back to text/html (or whatever you have set as your default...). Why should a JSP be more strict than this with it's include directive? The file you are including is required to be a valid URL -- which means it could be accessed via the webserver anyway. Remember, Tomcat is the RI and should implement the spec as closely as possible. I've gone back and looked through my books on JSP, and every one of them says that you can use any file extension with the jsp:include directive. However, none of them say you have to register that extension as a valid MIME type first. At the very least, it's confusing for someone who expects it to work when it doesn't -- especially when there's no documentation on it.

Re: Unable to include *.sum files (Again)
Ok, but what happens if you don't have control of the included file? Your database or other source produces dynamic reports for you and you need to include them into your JSPs. My question is this: if nearly every webserver on the planet can use a default MIME type of text/html, why can't this? That would solve the problem. Restricting output to registered MIME types seems a little heavy handed to me.

So, I don't know the answer to that. Remember though, we're talking about included files -- by their very nature, they don't necessarily represent *entire* files. They may only be pieces of a bigger file that is ultimately displayed to the surfer. I can understand that the file sent to the browser must have a sensible MIME type, but must all the pieces that the file is built from also have registered MIME types? I'm not sure that makes sense. Also, I always thought MIME types, in this context, were available so the browser could decipher what kind of file was being retrieved and display that file correctly. I never thought MIME types would be used to limit my flexibility with JSPs in this way. Thanks, --jeff I understand what you are saying, Jeff. But the bottom line is that the JspWriter is the source of the out implicit object in this instance. Apparently your bottom line is that you want to use the extension to pass information, instead of an extension in any true sense. I think it is a little harsh to have them expect that use. That said, and I may be wrong, why not toss the 'dynamic values in prior to the extension and trick the JspWriter, e.g. instead of com.site.123 us com.site.123.txt or com.site.123.jsp. You are going to have to have a class read the url in any event. The other way is to put your dynamic information inside the included tidbit. That seems more intuitive to me than using an extension for information anyway.

Re: Unable to include *.sum files (Again)
I agree that there are workarounds -- there are always workarounds -- but Tomcat is the RI, so this is the place where we're supposed to figure this stuff out.

Re: Unable to include *.sum files (Again)
Hi Micael, Let's make sure we're talking about the same thing. If I include a file like: jsp:include page=./testTxt.sum flush=true / Why does it matter what the file extension of the included file is? Isn't the container just supposed to open the file and output it's contents at that particular spot in my JSP? Now, I agree that the contents of the included file will be affected by the MIME type of the response -- how the browser views those contents. If you include a file that doesn't match the MIME type of your response, it may not appear correctly in your browser. But that's not the point. The JSP spec says the page attribute must evaluate to a String that is a relative URL specification. When I pull up the testTxt.sum file in my browser, it displays correctly (it's only one line of text...). So, I should be able to include it in my JSP with the jsp:include directive. When I change the extension to .txt, .html, or .jsp it works. Anything else, even other registered MIME types like .doc, and it doesn't. (ok, I didn't try them ALL... :) I think this is a bug. The old Java Web Server used to have a similar bug where it would only include .htm and .html files. --jeff - Original Message - From: Micael Padraig Og mac Grene [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Friday, December 07, 2001 1:37 PM Subject: Re: Unable to include *.sum files (Again) At 01:31 PM 12/7/01 -0800, you wrote: Nope.

Re: Unable to include *.sum files (Again)
If it does, then it's violating the spec. The spec doesn't specify any extensions that can or cannot be included. It just says it has to be a String that is a relative URL. The string ./myText.foo satisfies that and the file myText.foo pulls up correctly in my browser with the following content: This is the myText.foo file! However, when you include the myText.foo file using the jsp:include directive, you get an exception. I think that's a bug.

Subject: Double check idiom broken - Tomcat uses it ?
Hi all:
We all know that the lazy-double-check idiom doesn't
apply to Java because of the Java Memory Model (JMM).
That is to say, look at code such as:
Example a)
// Set by any other thread other than #1
volatile boolean stop = false;
// Thread #1 runs this as long as
// stop is false. Only T1 will call this
// method, so not synchronized. hence
// broken due to staleness of 'stop'.
// synch for _visbility_ ALSO.
void foo() {
while (!stop ) { //... }
}
Example b): The lazy double check idiom
public static Foo haha = null;
public static getFoo() {
if (foo == null ) {
sychronized (Foo.class) {
if (foo == null )
foo = new Foo();
}
}
return foo;
}
Both examples are *guaranteed* to be incorrect.
Note, this is the case, *even* though I am using
'volatile' for the stop variable. For more on the
JMM, consult Item #48 in Effective Java (Josh Bloch),
look at Bill Pughs' page at:
http://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html
or check out Doug Lea's stuff.
Well, here is the thing:
Quite idly, and randomly, I was looking at:
org.apache.jasper.servlet.JspServlet
and I found:
snip
outDated = compiler.isOutDated();
if(!jsw.isInstantiated() || outDated ) {
synchronized(jsw){
outDated = compiler.compile();
if(!jsw.isInstantiated() || outDated) {
if( null ==ctxt.getServletClassName() ) {
snip
This is a complex use of double check type
code and is really hard to analyse because references
themselves and what they point to can have
different levels of staleness (according to the JMM).
So it's a turbo double idiom type usage, possibly
incorrect.
I just wanted to bring this to the attention of the
development team and make sure that *someone* has
really analysed this according to the JMM. (and
any other code, similar to this).

Re: Authentication problem...redirected to /null
You're not supposed to be able to reach the login page, except by accessing a secure page. The container is then responsible for displaying the login page and sending the user to the correct secure page, once they have been authenticated. So, rather than having a link to your login page from your home page, you should have a link to your main welcome page inside your secure area. Tomcat will then send the user to the login page automatically, if they haven't been authenticated. What version of Tomcat are you using? Unfortunately, in TC 3.2.x (possibly others, but I'm not sure) the container *redirects* the user to the login page which makes it possible for the user to then bookmark that page -- thus defeating the idea that they have to access a secure page first. The only way I found to get around this was to put my login page in a separate /login directory and then put an index.jsp file in that directory that redirects to my secure area. That way, anyone who bookmarked the login page was handled correctly. I'm not sure if this will work in other versions of Tomcat, though. Hope this helps! --jeff - Original Message - From: John Mikhail [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, December 05, 2001 5:36 PM Subject: Authentication problem...redirected to /null Hello, I'm wondering if anyone can help me with an issue I'm having with my web app. I have a web application that uses the JDBCRealm and I've defined all the roles and what not.

Re: tomcat configuration error

If you are copying Tomcat 3.2.4 on top of a Tomcat 3.2.1 installation, be aware that this is an untested form of installation. I would recommend installing Tomcat 3.2.4 in a new directory and updating the configuration and web apps to match your 3.2.1 installation. Normally the Unable to set CLASSPATH dynamically ... Setting your CLASSPATH statically message is just a warning. However, in Tomcat 3.2.4 this represents an error. Tomcat 3.2.4 includes JAXP 1.1 as the XML parser (consisting of jaxp.jar and crimson.jar) where Tomcat 3.2.3 and earlier included JAXP 1.0.1 (consisting of jaxp.jar and parser.jar). Note that with 3.2.4, it is crimson.jar that is found in the TOMCAT_HOME/lib, not parser.jar. There is a bug in the tomcat.bat file where it tries to build the CLASSPATH setting staticially, i.e. with a bunch of SET commands. This portion of the batch file is only used on Win9x systems when a directory in the TOMCAT_HOME path isn't a DOS 8.3 name. This portion of tomcat.bat still specifies parser.jar instead of crimson.jar. Change all parser.jar references to crimson.jar in tomcat.bat and you should be okay. You could also do what the message says and manually set your TOMCAT_HOME using DOS 8.3 names, (i.e. SET TOMCAT_HOME=C:\TOMCAT~1 ), or make sure all directories in the path to Tomcat are DOS 8.3 names, (i.e. C:\Jakarta\Tc324 ).

I'm experiencing a problem with SOAP message-style services when using Tomcat 4.01. Folks on the soap-user mailing list suggested that this may be a classloader problem in Tomcat 4.01. When trying to access any message-style SOAP service, my client receives a no signature match fault. I have no problem with RPC-style SOAP services, the same message-style SOAP services work fine with Tomcat 3.2.3, and the signature of the my message-style services is of the correct form; ie: public void serviceName( Envelope env, SOAPContext req, SOAPContext res ) throws IOException, MessagingException; What makes me think that this is a classloader problem is that I can make the fault go away by removing $CATALINA_HOME/webapps/soap/WEB-INF/classes/org/. But I don't understand why this makes the fault go away, and it's clearly an unacceptable hack. Is anyone else experiencing this problem?

If you want the JVM to use more of the system's memory then start it up using the switches: -Xms initial heap size -Xmx maximum heap size (This is for the Sun 1.3 JVM, but I expect the HP JVM has an equivalent) so for 100MB initial heap, 150MB maximum heap you would change your startup script to override the defaults: java -Xms100M -Xmx150M classname In catalina.sh (Tomcat 4) there is an environment variable CATALINA_OPTS that will add extra parameters to the java command so I just set CATALINA_OPTS= -Xms500M -Xmx1000M.

I was asking still questions : - What's better ? a repository for each project or a module for each project ? We don't use either, the projects are simple sub directories under one root in the repository. - Is it a good idea to use CVS for binary files ? i was thinking about class files, and all the jpeg/gif files... In general yes. But I would just put class files in the repository if they are not build from sources. And make shure that you use/configure cvs correct to handle binaries. (Otherwise you might expierence some surprises.) - What would do the site construction script ? pre-compile the jsp and the servlet maybe ? Have u got examples of script that i could see ? Checkout all needed files for a given tag. Compile the java classes, make a jar of them, fill a test database. In our environment we have several files that are the same over the project that are placed outside the project directory. Our installation script copies these files in the deployment site where our webserver runs and mixes them withe project specific files. We have automated the setup of a webserver, so that we can setup a new instance of the same project in few minutes once we have defined all configration parameters. (Even the initial setup of new project doesn't take much longer) This we use to build the web server up to several times a day. The examples won't help you much because they still work with good old JServ. - I think we will need differents branches : - one for each stable release - one for a beta developpement but fonctionnal, few bugs. - one for an alpha developpment, used to backup the progress I wouldn't do to much branches. Just use Tags to mark this versions. works( i am hesitating here with a branch for each developper ). A clear NO! to this approach. For example, a developper that has not finished a work at the end of the day will update the alpha branch. If a developer isn't ready, the he shouldn't checkin. So the your alpha branch is just the developers workplace in my world. (What do you win with this checkin ?) A developper will update the beta branch when he thinks his source is quite ok. The stable release will be built after hard testing of the global application. - Last question : which utils do u use for cvs ? there is wincvs, i've seen webcvs too. Are there any others ?

Re: AW: Java program interferring with Tomcat
Sure it does. Changing the transaction isolation level affects how data is read from the database. TRANSACTION_READ_COMMITTED waits for a read lock before reading data and ensures that the data being read is in a consistent state. Lower isolation levels may allow data to be read that's inconsistent -- data from a transaction that hasn't been committed, yet, and therefore may be rolled back. However, that doesn't mean lower isolation levels are bad. They can relieve a lot of locking contention on the database when used with queries that don't need perfectly consistent data. It just depends on how critical the info you're pulling with this particular query is. For example: are you tallying the number of visitors to your website or are you doing financial transactions? With the former, reading dirty data may not matter that much. With the latter, it may be critical that you have consistent data. If your data's not that critical, you may get a lot of benefit from lowering your transaction isolation level.

Re: VHosts causing app to load twice
Hi Steve, I ran into the same problem when trying to configure mydomain.com and www.mydomain.com under the same VHost. I was using the ServerAlias directive in Apache. Tomcat (3.2.x) needed two Host directives to deal with both names, which would give me two instances of my webapp. I finally gave up and only implemented the www.mydomain.com I'm under the impression that TC 4.0b7 has the ability to add aliases much like Apache using an Alias directive in server.xml. You might want to check that out. Also, someone posted a patch for 3.2.x to the tomcat-dev list a month or so ago that allowed you to use a list of domain names in your Host directive, like: Host name=mydomain.com www.mydomain.com 111.222.333.444 You might want to search the dev archives and try this patch.

Re: VHosts causing app to load twice
Hi Larry, It doesn't really make sense to set up Name-based virtual hosting this way. In essence, your saying all requests for 111.22.33.44 should go to the same place as all requests for www.foo.com (in httpd.conf). In that case, I think you should stick with IP-based vhosts. Your Apache config would then be: VirtualHost 111.22.33.44 /VirtualHost With this setup, the host header is ignored and all requests to 111.22.33.44, no matter what domain they come in on, will go to the right place -- from Apache's standpoint, I don't know if it's handled correctly in Tomcat. You should be able to set up your Host directive in server.xml to catch the IP Address and make it work that way, though. I think the real problem with Name-based vhosts comes when you're trying to point more than one domain name at the same Tomcat webapp: NameVirtualHost 111.22.33.44 VirtualHost 111.22.33.44 ServerName foo.com ServerAlias www.foo.com ... /VirtualHost VirtualHost 111.22.33.44 ServerName bar.com ServerAlias www.bar.com ... /VirtualHost Now, if you want foo.com, www.foo.com, bar.com, and www.bar.com to all point at the same webapp, there's no way to do it without having four different instances of your webapp -- at least not in TC 3.2.x. I don't know about 3.3, but I think 4.0 has an Alias directive. I'm not sure if it's actually implemented, though. It may be kind of extreme to have different vhosts pointing at the same webapp, however I think it's pretty common to want foo.com and www.foo.com to point to the same place. It's really unfortunate that Tomcat (3.2.x) doesn't handle this without having to instantiate two different webapps. I'd be interested in fixing this in 3.2.x, if development wasn't already frozen...

The point of: NameVirtualHost 111.22.33.44 VirtualHost 111.22.33.44 ServerName www.foo.com ... /VirtualHost was that mod_jk would identify the host as www.foo.com for both Both http://111.22.33.44/...; and http://www.foo.com/...;. Thus, Tomcat could match it to a single context identified by www.foo.com. I can't claim to understand the NameVirtualHost directive very well, but without it, I believe that mod_jk would identify the host as 111.22.33.44 instead of www.foo.com for httpd://111.22.33.44/ Ok, now I see the problem that you're describing. However, I still think this can be solved with an IP-based vhost where the config would be: VirtualHost 111.22.33.44 ServerName www.foo.com /VirtualHost Notice there's no NameVirtualHost directive. Here we're telling Apache that every request that comes in on this IPAddress will have it's ServerName set to www.foo.com. The only time you would need the NameVirtualHost directive is if you want to set up more domains with the same IP. For example: NameVirtualHost 111.22.33.44 VirtualHost 111.22.33.44 ServerName www.foo.com . /VirtualHost VirtualHost 111.22.33.44 ServerName www.bar.com . /VirtualHost Now, Apache will use the host header supplied by the browser to figure out which vhost to send the request to. If no host header is supplied, I believe it defaults to the first vhost in the list -- problematic for browsers that don't supply a host header. I don't think there's that big of a difference between the way you had it and my first config above, just saves a bit of typing in httpd.conf and looks cleaner from an Apache point of view. The results are probably the same... Obviously, I'm coming at this from the point of view of keeping mod_jk and Tomat happy, and not necessarily what is normal for Apache. By the way, ApacheConfig in Tomcat 3.3 also supports the following for ServerAlias: server.xml: Host name=www.foo.com address=111.22.33.44 Alias name=www.bar.com / Context ... / /Host which would generate conf/auto/mod_jk.conf: NameVirtualHost 111.22.33.44 VirtualHost 111.22.33.44 ServerName www.foo.com ServerAlias www.bar.com ... /VirtualHost Cheers, Larry Cool! This is what I was looking for in 3.2.x. Any hopes of migrating this back into 3.2.4 or later? Kinda silly not to have this functionality. Also, can you have multiple Alias directives? (I'm not even sure if you can do that in Apache...) Thanks, --jeff

Hi All!
Different encodings support in Servlet/JSP is an ancient well-known problem.
The setCharacterEncoding() method of HttpServletRequest allows to change
request
encoding before reading parameters. Thus, servlet is able to change encoding
in
accordance with its needs. (Small lyrical digression: what does this
encoding mean?
I'll post my thoughts about it separately)
Howevet the problem still exists in JSP (there were several postings about
the problem in
this maillist). The purpose of this mail is to propose a solution for
encodings support in JSP.
Problem description
===
A JSP programmer is not able to change request encoding for incoming JSP
request, since
"This method [setCharacterEncoding] must be called prior to parsing any post
data or
reading any input from the request. Calling this method once data has been
read will
not affect the encoding." (Servlet 2.3 Spec). This happens because request
parameters
being read inside org.pache.jasper.servlet.JspServlet, before calling
generated JSP-servlet.
As a result we have the following behaviour of compiled JSP for non-English
environments:
1) incoming request being read using 'ISO-8859-1'
2) getParameter() method returns a value in 'ISO-8859-1', but JSP-servlet
suppose the
return value has JVM default encoding (say "KOI8-R") -- here is ???
instead of
real parameter value. Here is a problem.
Problem solution
There should be a configurable optional parameter for JspServlet (say
'requestEncoding') to
change request encoding. According to this parameter JspServlet should call
setCharacterEncoding()
before processing request. It does not conflict with JSP 1.2 Spec, since
there are now any
words about default encoding of incoming request over there.
I have made neccessary changes to implement this feature in
tomcat-4.0-20010807. It works fine
with different Cyrillic encodings. (Suppose the same result for the rest of
non-Latin1 encodings).
I clearly understand that proposed solution is not a panacea and it's a
subject to discuss.
Regards,
Andrey Aristarkhov
Diffs are followed (also as attachments). I have also attached a sample JSP
for encoding testing.

How about running an application that periodically posts to

How can a servlet be automatically be invoked by

Usul
I think a better way is to write a servlet which is configured
as a load on startup servlet which forks a separate scheduler
thread which then defines tasks to be completed at specified
interval(using a properties file or init params...). The
Thread(Runnable) will essentially be a infinite loop which will
check to see if it's time to run certain tasks. i.e.
while(1) {
if ( /*somethings true 1*/ ) {
/*perform task 1*/
}
if ( /*somethings true 2*/ ) {
/*perform task 2*/
}

Yeah, that's the general idea. That was the //... part any additional
cleanup between states and a wait state. Otherwise the process, depending
on the performance of your separate scheduled jobs and the frequency of
them, could pretty much lock the processor down. This is meant as a
rudamentary example. This is the generic model of a scheduling

OK, let's see how good you folks are: I work for a large national not-for profit membership organization. We've got a large database application that we serve to our members from a small group of servers out of our national office. About a week ago, we upgraded our servers, moving from Apache JServ/mod_jserv/AJP12 to Tomcat/mod_jk/AJP13. Ever since the upgrade, our servers have been HIGHLY unstable (our 3 busiest servers have each crashed at least once a day for the last week) and we're HIGHLY confused. The only real change has been the move to Tomcat, which we thought was a large upgrade, but our app has been acting as if we downgraded! Before the upgrade, application was having some performance issues (record locking, result set not found errors), probably caused by the large load on our servers combined with some inefficiencies in the code. After the upgrade, the same performance errors exist, but seem to be magnified, as if Tomcat is working SLOWER than JServ. But here's the worst part: At least once a day (usually after running for a while), the application will simply stop responding - users will attempt to save forms and/or navigate between pages and will never get a respond (eventually they'll get a Page Cannot Be Displayed Error). When the server is in this state, we check the running processes and we see lots of java threads loaded and waiting for response, but none of them is RUNNING, so I don't THINK this is a runaway thread problem. Once the server hangs like this, our processor usage by the JVM will go down to 0% and stay there until we restart Apache and Tomcat. Here's our specs: SERVER SPECS (average): Dual Pentiums (1 Ghz) 2.5 GB RAM Red Hat Linux 7.1 OLD CONFIGURATION: Apache 1.3.14 Apache JServ (with mod_jserv and ajp12) IBM JDK 1.3-5 Cloudscape 3.5 NEW CONFIGURATION: Apache 1.3.14 Jakarta Tomcat 3.2.2 (with mod_jk and ajp13) IBM JDK 1.3-9 Cloudscape 3.5 So... does anyone out there have any idea why we're seeing these problems? Where should we focus our investigation? Should we just go back to JServ, or is Tomcat REALLY better?

Re: How to forward with new request/query string?
Hi Erin, You can't change the original request (at least, I don't think you can...) -- but you can add info to the request before forwarding it on to your jsp page. Just add the extra info to the query string of the jsp your forwarding to: String location = myForward.jsp?foo=barbaz=1; RequestDispatcher rd = request.getRequestDispatcher(location); rd.forward(request, response); The parameters foo and baz will now be available in myForward.jsp, along with all the original request params. If foo and baz exist in the original request, calling request.getParameter() will return the newly set value and calling request.getParameterValues() will return all values for that parameter. You can also store info in the request object using setAttribute() and retrieve them in the jsp by using getAttribute(): (in servlet) request.setAttribute(key, value); (in jsp -- if the value is a String object) String value = (String)request.getAttribute(key); Notice that you have to cast the object back to the correct type in your jsp.

How many threads have you specified as max_threads in your PoolTCPConnector for ajp13 in your server.xml file? If you haven't done this, and you're running a reasonably high load, you should take a look at the minimal TC user's guide here: http://jakarta.apache.org/tomcat/tomcat-3.2-doc/uguide/tomcat_ug.html The last example at the bottom of the page shows how to configure max_threads, max_spare_threads, and min_spare_threads for the PoolTCPConnector class. Tomcat doesn't react gracefully if the max_threads number is ever reached and exceeded. I believe the default max is 50 threads. If you're getting more than 50 concurrent connections, you need to raise this number or you'll have problems.

Re: Okay. this is getting annoying.
From your previous posts, you're server.xml entry is not correct. You can't reference multiple IP's, domains, etc.. in the Host directive. - My most recent attempt had this in server.xml Host name=206.180.224.76 : www.pedsforless.com : pedsforless.com debug=0 appBase=/home/peds/public_html unpackWARs=true Context path= docBase=/home/peds/public_html debug=0/ /Host - If you want to access this as www.pedsforless.com and pedsforless.com, you need to set up two independent Host directives. (I'm assuming you're using TC3.2.2) Also realize that this will instantiate all of your servlets twice under two different contexts.

Re: List traffic et al
I'm not sure that I agree with the idea that I have to wade through all these messages for the good of the list. As I said, I have no experience with Tomcat on Windows, so I'm not interested in Windows specific issues nor can I help to solve them. Splitting along platform lines should retain a relatively good mix of newbies and experienced developers in each list, so I don't see the problem you are pointing out. In any event, even if the list is split on basic vs. advanced topics, advanced users who wanted to help the community could subscribe to all lists. I don't think it's necessarily bad to want to subscribe only to the lists you feel you can learn from. I've been lurking and posting for about 9 months now and it seems that the same basic group of people answer a majority of the questions. I used to answer a lot more than I do now, but I'll admit that I get pretty frustrated answering the same questions over and over when I know the answers can be easily found in the archive. Is it selfish or bad of me to skip over questions I used to answer, or should more responsibility be placed on the person asking the question? (rhetorical, because there's no way to control whether or not people actually search the archives before posting...)

Re: AW: List traffic et al
In a perfect world, yes, I totally agree. However, in the real world, who's going to enforce the guidelines? (we already have guidelines that few people pay attention to...) Reposting the guidelines and links to the FAQ and archive on a regular basis would probably help, and I agree that it should be done. Personally, I don't care about the volume on the list. I have a broadband connection and it only takes me a couple of seconds to download all the daily messages. However, I think Tomcat is a broad enough subject to warrant more than just one generic list. I think a couple of focused lists would help people with non-generic questions. And, as Milt Epstein points out in a later post, involvement may actually increase on smaller, focused lists. I don't think the volume on the tomcat-user list will decrease much at all, even if it is split. However, splitting will allow people with focused interests beyond getting Tomcat up and running to participate without being deluged with messages they may not be interested in. More choices are usually better than less. --jeff From: Nico Wieland [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] Date: Fri, 6 Jul 2001 13:17:13 +0200 To: [EMAIL PROTECTED] Subject: AW: List traffic et al i agree 100%. i think a _good_ thing would be to include these guidelines in the confirmation message one receives after subscribing to the list. this is the way how it's done eg. on sun-managers, they post the guidelines once a month. it's the most disciplined list i know. -nico Rather let all of us try to reduce volume(both in size and number), it does not require much effort.

Where is org.apache.tomcat.servlets.InvokerServlet ?? According to the cvs, it was dropped a year ago, and yet in all the places that I've seen where it shows you how to change the servlet mapping (eg. from /servlet/* to /jbin/* in my case), it says to do this... servlet servlet-name invoker /servlet-name servlet-class org.apache.tomcat.servlets.InvokerServlet /servlet-class /servlet servlet-mapping servlet-name invoker /servlet-name url-pattern /jbin/* /url-pattern /servlet-mapping For me, this doesn't work. I can do something specific, such as: servlet servlet-name /jbin/xyz /servlet-name servlet-class xyz /servlet-class /servlet That works. But the generic doesn't. I can't find InvokerServlet anywhere in the source or binaries, nor can I find any mention of the ...servlets package it's in. So it's either accidentally missing, or only the name is there for backwards compatibility, or the remapping mechanism is fundamentally broken. Or I've missed something!

Re: mod_jk and mod_perl
I would go with option #1 -- build apache with mod_perl statically and mod_so, then load mod_jk dynamically. I think you're going to have a lot of work trying to get mod_jk to compile statically with apache, because the developers haven't released an easy static version. You'd have to integrate the mod_jk code into the apache source yourself. The reason you can't use perl 5.005 may be your apache version (or apxs version). You may also be able to switch to an older version of apache to compile mod_perl as a DSO. The other option is to upgrade perl. It's really not that hard and shouldn't cause any major problems. You may want to try that first. (personally, I think it's easier to upgrade perl than to install apache for the first time...)

Re: ** JVM and Processes
When Java first came to the Linux platform (via the Blackdown port), green-threads were the only option. Native threads took a little longer to implement, but are a much better option for the reasons listed in the previous message. So, I would recommend avoiding green-threads unless you have a specific reason for using them. A lot of people freak out when they see the number of processes being reported by ps or top, without realizing that these are merely threads and not full-blown processes. If you have a lightly loaded Tomcat, you can tune down the number of threads being spawned by using the max_threads, max_spare_threads, and min_spare_threads parameters of the PoolTCPConnector in your server.xml file. For an example of this, take a look at the tomcat user's guide: http://jakarta.apache.org/tomcat/tomcat-3.2-doc/index.html Do a find in your web browser for max_threads. I use this to limit the number of ajp12 threads and maximize ajp13 threads -- because I'm using ajp13 for my servlets and ajp12 only for startup/shutdown of Tomcat.

On linux a system thread takes the form of another process, but one that shares memory etc. with another process. This is why if you create a program that allocates 100 megs of memory, then spins off 10 threads, it looks like 10 processes each taking up 100 megs of memory, when in fact the amount of memory is 100 megs + 10*overhead for each thread (not much more than 100 megs). On WIN32 systems, threads do not show up as separate processes, they are separate threads of execution inside the same process (essentially the same as the Linux implementation with differences too subtle to care about) Green threads on the other hand use timers, signals, setjmp etc. voodoo to simulate threads within one process. Essentially taking over the scheduling from the kernel. I believe the command-line option for green threads is simply -green as in java -green MyThreaddedApp If you have a multi-cpu system, green threads will only take advantage of one cpu, whereas native threads will use all the cpus on your system (that's the theory anyway) I've heard of problems with blocking I/O with green threads, but have no first hand knowledge.

Re: ** JVM and Processes
Hi Adam, No, the garbage collector runs as a low priority background process and, on a lightly loaded server, may never get called because the server's not using enough resources to warrant it. I really wouldn't worry about it too much and I would definitely avoid killing threads individually, especially since you're now utilizing a Pool connector. (you don't want to kill threads that are marked as available in the pool...) The min_spare_threads and max_spare_threads settings are supposed to take care of cleaning up any extra unused threads that are laying around. I think the best benefit you could do yourself would be to upgrade your 3.1 version of Tomcat to the newly released 3.2.2 final to take advantage of upgrades and bug fixes.

This is why if you create a program that allocates 100 megs of memory, then spins off 10 threads, it looks like 10 processes each taking up 100 megs of memory, when in fact the amount of memory is 100 megs + 10*overhead for each thread (not much more than 100 megs). On WIN32 systems, threads do not show up as separate processes, they are separate threads of execution inside the same process (essentially the same as the Linux implementation with differences too subtle to care about) Green threads on the other hand use timers, signals, setjmp etc. voodoo to simulate threads within one process. Essentially taking over the scheduling from the kernel. I believe the command-line option for green threads is simply -green as in java -green MyThreaddedApp If you have a multi-cpu system, green threads will only take advantage of one cpu, whereas native threads will use all the cpus on your system (that's the theory anyway) I've heard of problems with blocking I/O with green threads, but have no first hand knowledge.

Re: Virtual Host Context Aliasing
Hi Daniel, I have the same problem -- wanting to alias more than one host name to a single context. Unfortunately, there is no way to do this. I've heard that the 4.0 version of Tomcat may have some abilities for doing this, but it's not nearly as straightforward as Apache's ServerAlias directive. For now, I've turned off zzz.net (using your example) in my DNS and am only serving www.zzz.net.

Re: How to debug a missing servlet error?
Hi Chris, Tomcat should recognize /servlet/briefXSL without the explicit servlet-mapping you are using -- but I don't know if that is what's causing your problem. For all my servlets, I have the following type of entry: servlet servlet-namebriefXSL/servlet-name servlet-classcom.smartbrief.BriefXSL.Servlet/servlet-class /servlet The default Invoker automatically sets up /servlet/ as a mapping for all your defined servlets. So, the above should be enough to get /servlet/briefXSL to pull up correctly -- without the servlet-mapping you have below.

Re: Setting up Virtual Hosts
I'm not sure how Apache forwards the host info to Tomcat. If you're using an IP Address in your VirtualHost directive in Apache, then Apache may be sending the IPAddress to Tomcat as opposed to the hostname specified by the ServerName attribute. So, if you're trying to catch host names in your server.xml file, rather than IPAddresses, it may not work. However, this is all speculation and I don't know if that's how it really works. It would make sense, though. The docBase is where Tomcat serves all your files from for that particular webapp. Check out the Developing applications with Tomcat Howto in the docs for an example of setting up source and deployment directories. --jeff From: Glen Eustace [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] Date: Mon, 21 May 2001 05:16:01 GMT To: [EMAIL PROTECTED] Subject: Re: Setting up Virtual Hosts I don't know if it makes a difference or not, but I've always had the same host names in my Apache VHost config and my server.xml file.

there is no gc on static objects. static objects(methods,fields, or

are created once on startup and there is only one instance of the method
or
field ever created that all requestors to your class will use. But with
Tomcat I do believe that if you have the same class in 2 different
contexts,
that it will load two separate instances of your bean due to the different
class loaders.
This also means that if you are writing to the static fields on the

the

Subject: Bean Choices (code question)
I'm sorry if this is a little off-topic, since it is more about java
code,
but I thought Tomcat users would be interested/knowledgeable about the
way
beans work.
I have a lot of informational beans that hold static reference data
(think
ISO codes, State abbreviations, etc...) With these types of beans, I
have
the choice of instantiating a singleton object reference to the bean and
accessing the methods through the object, or making all the methods
public
static so I can access them via BeanName.method(). For the former, the
bean
does all of it's initialization and database access in it's constructor
and
my JSP's have something like the following at the top:
%!
private static BeanName bean = BeanName.getInstance();
%
For the latter, the bean does all of it's initialization and database
access
in a static block:
static {
// bean initialization and DB access
}
and my JSPs reference the static methods:
%= BeanName.method() %
My question concerns the way beans with all public static methods are
instantiated and garbage collected. Because these beans hold unchanging
reference info, I only want the data loaded from the database once the
first
time the bean is referenced. For beans with all public static methods,
since there are no object references to them, when are they garbage
collected? Is it possible that the bean will be unloaded and the code in
my
static block will be re-run when the bean is next referenced? Or do
these
all static objects somehow stick around forever? For the singleton, I
know
the object will last as long as the JSP is loaded, because there is a
definite object reference to the singleton. I'm a little unclear as to
what
happens with a bean that has all public static methods, though.
Can anyone shed some light on this?
Thanks,

Re: Bean Choices (code question)

Therefore static methods can only call other static methods in the same class. - it doesn't metter that if this class is a all static method style class or Not,i.e., this class can have all of the following: % static init-block/non-static init-block % static field/non-static(instance) filed % static method/non-static method - only when this class is being loaded into the classloader, static init-block will be invoked(i.e., normally, static init-block only will be invoked One time), now we only have a Class object of my-class, we don't have the instance object of my-class. - I am not sure if the above is righ when Java Reflection is used to find/load this class(like a Servlet container does) I think this is where the classloader(s) issue comes into account and that separate instances in different contexts would be considered different classes. There was a very good explaination of tomcat's classloading discussed in a previous thread : http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg13260.html Bo May.18, 2001 Charlie
Re: Changing Tomcat's User ID
Correct me if I'm wrong, but if you're running with Apache and ajp12 or ajp13, you shouldn't have any problems because Tomcat is only responding on ports 8007 and 8009. You only have problems when you're running Tomcat stand-alone and you want it to respond on the normal http (80) and https (443) ports. However, I've heard it's kind of a nightmare getting all the directory and file permissions correct for the non-root user. --jeff - Original Message - From: Tim O'Neil [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, May 18, 2001 4:00 PM Subject: Re: Changing Tomcat's User ID At 03:05 PM 5/18/2001 -0700, you wrote: I'm running tomcat 3.2.1 on Solaris.

I read through the documentation on it, and it mentioned using su inside of the start scripts, but that method did not work. Any help would be greatly appreciated. Thanks, Jason Majors You can't do that, unless you're willing to run it on a port 1024. Remember, ports below 1024 are root access only. Apache gets away with it because it's an admin process that runs as root + a web server process + its native code. Tomcat, being Java, is going to have a hard enough time without a root process to kick it off.
Re: Struts, Velocity, JSP, XSLT?
Speed is one consideration. XML and XSLT are great, but are very processor intense for all the translation/transformation that is done on the fly. --jeff - Original Message - From: Richard Draucker [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, May 16, 2001 9:18 PM Subject: Struts, Velocity, JSP, XSLT? I've been happily using servlets with Tomcat for some time. I'm now happily using XSLT for output (Xalan/Xerces) mostly cause, oh hell, cause 'everyone' says XML is the way to go. The question is... is Velocity vs. XSLT simply a religeous difference? I mean, is there something Velocity and Struts offer over XML/XSLT? Thanks, Richard
Re: Cookies
Look at the session-timeout directive in your web.xml file. The default is 30 minutes. --jeff - Original Message - From: Oki DZ [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, May 16, 2001 10:26 PM Subject: Cookies Hi, 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? TIA, Oki
