AW: How to write a servlet that handle request for .xml documents
Wether doGet() or doPost() is called depends on the kind of request that is sent to tomcat, not on the file type. If tomcat receives a GET-request doGet() is called, if tomcat receives a POST-request doPost() is called. If the client is a browser, all href, src attributes and forms with method=get are GET-requests. Only forms with method=post are POST-request. Other clients can choose arbitrary methods to do requests. This is basic knowledge before you even can start to write servlets and this list isn't the platform for this kind of questions. -Ursprüngliche Nachricht- Von: Aaron Chan [mailto:[EMAIL PROTECTED]] Gesendet: Freitag, 27.

But for servlet debugging how to go about doing the same. Hi. I've never done this, so im not 100% sure, but this should work according to docs. Modify catalina.sh-script so that CATALINA_OPTS-parameters value is the options you use normally (-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=,server=y,suspend=y), except add -Djava.compiler=NONE to it. Debugging servlets is propably a little different then normal java apps. Docs say that 1. Set one or more breakpoints in your servlet code. 2. From the Run menu, select Debug servletname.java. 3. Start the servlet running (for example, start your web browser and open a connection to the servlet). 4. Debug as normal. If your using Oracle's JDeveloper you should propably use JDevelopers servler.jar instead of tomcats.

BasicDataSourceFactory and validationQuery parameter
Title: BasicDataSourceFactory and validationQuery parameter Has anyone used (successfully) the validationQuery parameter specifiable in server.xml for a JNDI datasource. --- background --- When specifying a JNDI datasource resource a parameter exists - validationQuery - that can be used to validate a connection before returning it to the client. - sounds useful ! Is this implemented? I have set up a connection pool with this parameter set and all runs fine. If I pull out the wire between Tomcat and the database (or terminate the listeners) I would expect that the validation query should fail, and some error get thrown. This does not seem to be the case. Instead an SQLException: socket connect failure (or something like that) is thrown when trying to use the connection returned from the pool. This rather extreme example raises another interesting (well I think so) question: If all of the connections in the pool are now broken - i.e. have had the socket reset - is it possible to refresh all of the pooled connections. What seems to be happening is that connections are returned and invalidated by the error until all broken connection are exhausted - then new ones are being created.

RE: How to write a servlet that handle request for .xml documents
So, if I am understanding right, what you want to do is:- 1. Client calls http://localhost:8080/home.jsp and there html code in there: a href=/file.xmla xml file/a 2. Client then calls http://localhost:8080/file.xml and you want to intercept this and redirect to a servlet http://localhost:8080/servlet/myServlet (which you have done?) 3. Now this is where you are stuck?? How do I know that file.xml has been redirected? 4. Do stuff and return file.xml. Is this right? Well if it is, back in step one you can have the link specify a href=/servlet/myServlet?xmlFile=/file.xmla xml file/a. But if you just want to be able to type in http://localhost:8080/file.xml and do you what you want, then you need to find out where you have come from, (been redirected from), you might be able to use 'request.getRequestURL()' this would only work however, if tomcat redirects without sending a proper 'response.sendRedirect()'. Other than that I don't know of a way to do what you want, hope this all helps somehow.

RE: How to write a servlet that handle request for .xml documents
Hi, I tried understand the JspServlet source and I have already solve the problem. Thanks for your help again. -Original Message- From: Nicholas Orr [mailto:[EMAIL PROTECTED]] Sent: Friday, September 27, 2002 4:14 PM To: 'Tomcat Users List' Subject: RE: How to write a servlet that handle request for .xml documents So, if I am understanding right, what you want to do is:- 1. Client calls http://localhost:8080/home.jsp and there html code in there: a href=/file.xmla xml file/a 2. Client then calls http://localhost:8080/file.xml and you want to intercept this and redirect to a servlet http://localhost:8080/servlet/myServlet (which you have done?) 3. Now this is where you are stuck?? How do I know that file.xml has been redirected? 4. Do stuff and return file.xml. Is this right? Well if it is, back in step one you can have the link specify a href=/servlet/myServlet?xmlFile=/file.xmla xml file/a. But if you just want to be able to type in http://localhost:8080/file.xml and do you what you want, then you need to find out where you have come from, (been redirected from), you might be able to use 'request.getRequestURL()' this would only work however, if tomcat redirects without sending a proper 'response.sendRedirect()'. Other than that I don't know of a way to do what you want, hope this all helps somehow.

I don't see any class path lines in the workers2.prop file.
Grab a default one from your connector build sources , and don't change
anything excepts the paths, and see if it will work for the /examples dir.
Especially pay attention to these lines
OPT=-Djava.class.path=${TOMCAT_HOME}/lib/tomcat-jni.jar;${TOMCAT_HOME}/server/lib/commons-logging.jar
OPT=-Dtomcat.home=${TOMCAT_HOME}
OPT=-Dcatalina.home=${TOMCAT_HOME}
OPT=-Xmx128M
I have to go home now, I hope you get it working.

Hallo,
thanks for the reply. Again, I installed the Apache (/opt/apache2) and
Tomcat (/opt/jakarta) from source. Both are running well. I compiled the
jk2
connectors and made the configuration. Apache is loading the module, but
couldn't find the jk-worker. The Tomcat installation gets an error in the
Log-File. It seems that Apache can no find the Tomcat process
My environment is a Suse Prof v8.0, 2.4.18 kernel
I need some help.

Get all hosts while initializing a context
Hi, I´m wondering if the following is possible. I´m implementing a servlet context listener which does some initialize work for my webapp. Here, I want to get a list of all hosts (server name and port) my webapp is available on. If haven´t found a way to do this with the regular servlet api. I thought of passing a reference to the server.xml file to the context listener as parameter in my web.xml. But I think this is a dirty and insecure way. Do you have any other ideas? Thanks Stefan -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

When I look into the server.xml it has a connector for port 8080 using coyote. But I note this is in the Service name=Tomcat Standalone section.

Not sure about the step they called dsp though, not in your instructions. I moved copied the missing jni_md.h file into the same directory as the jni.h file and then ran ant from the /jk/native directory and it finished OK. Then I cd to /jk/native and ran ant again (all ant native in the /jk/build.xml file does is run these 2 build.xml file anyway). It failed massively, lots of missing header files, I am not sure if this is because the Mandrake instal of Apache 1.3.23 is not a full one, but as I don't need to support it I assume it is OK. I then went to copy the build jar files to the /var/tomcat4/server/lib directory where I found the tomcat-coyote.jar. The tomcat-jk2.jar is smaller than the incumbent by 1K and the tomcat-jk.jar is 21.2k compared to the incumbent's 64.1KB. I assume this is because mine does not have support for Apache 1.3? Anyway I left the incumbents there. Now I get the problem in the apache2 error_log where it says there is no worker file of worker file. Since there is no /var/tomcat4/conf/jk/mod_jk.cong-auto as the docuemntation says there is (how can this be!) I added the Jk... commands to the httpd.conf file.

I still had a doubt about the jk module that was compiled for 4.1.10, but i downloaded 4.1.12 connectors and recompiled them. I tested both jk and jk2 with ajp3 connector with same results. Also the application was recompiled against 4.1.12. If nobody has any other hint, i'll open a bug. According to my testing, this doesn't happen with Tomcat standalone on 8080 (or you'll have to explain how to get the problems). Since the requestURI buffer isn't used much in Tomcat, it is possible that Coyote JK2 mutates it, creating the incorrect logs.

Thanks to all that have replied, the problem is still here and what follows are the tests I did To clear the issue here it is what I am doing -- - Clean install of redhat 7.2 or Suse 7.1 (same results for both platforms) - Clean installation of tomcat 4.1.12 - Clean installation if JDK 1.4.1 (the same happens with 1.4.0.2 or 1.3.1) - What I am doing is http://localhost:8080/ and keep refreshing that with F5 - I am NOT testing my own servlet.

Something like 30212 30220 31016 31040 31576 - I did try the various suggestions and as far as I can tell it is not a pure memory issue but it probably is a resource issue, maybe a file not closed or a socket ...

HOW TO: How do I allocate memory in JVM for extra virtual hosts
Hi all I am running tomcat 4.0.1 with virtual hosting and was wondering how much memory to allocate to each additional host. By default, we use 64M for one host but adding another 64M for second host seems excessive considering it's the same tomcat instance. However, if we add a lot the JVM will use more memory before garbage collection and we've seen a 30 second (!!!) delay when using 1G Ram on JVM as it just kept using memory until it ran out. It then had almost 1G of ram to garbage collect. How can I force garbage collection to be more aggressive and do it more often when garbage is small enough not to cause a problem? As we need this to run in a production environment we cannot possible allow a JVM to go for a garbage break for 30 seconds Any insight or help is greatly appreciated.

It is usual to create a dedicated user for each tomcat instance. But I wouldn't recommend to use 'tomcat' as user name, we prefer to use application level names for users.

Re: javax error
I can't tell the exact error from the stack trace and code. When this
happens to me, I wrap the entire page in a try/catch similar to the
following:
%try { %
YOUR JSP PAGE HERE
%
} catch(Throwable e) {
e.printStackTrace();
out.println(D'oh: an error occurred - go see the catalina.out!);
out.println(Here's a hint: PRE + e + /PRE);
}
%
The stacktrace will show where the REAL error occured and you can follow
it from there. Currently the error is being wrapped by multiple
ServletExceptions and the error handler(by tomcat) isn't logging deep
enough. (I think)

1. you want me put another try over this block?
or
2. make another page and then include this page?
if it's optione 1 then doing that doesn't help. This exeception is
comming from the code generated by tomcat. It doesn't even seem to get
to my code. If an exception is generated by my code then I should have
caught it and not the exception handler code generated by tomcat.
Another question is, is this a bug in tomcat? Initially I was more
inclined to believe that it was my code but it seems that somehow tomcat
is screwing up.

The stacktrace will show where the REAL error occured and you can follow
it from there. Currently the error is being wrapped by multiple
ServletExceptions and the error handler(by tomcat) isn't logging deep
enough. (I think)

ScriptAlias
I have a ScriptAlias in Apache that works fine ScriptAlias /cgi-bin/db2www/ /QSYS.LIB/FLTCGI.LIB/DB2WWW.PGM/ Is there some way to do this kind of thing with an in-process tomcat? In other words can I define, somewhere in tomcat, a way to handle cgi scripts?

Re: javax error
No, there is probably and uncaught exception in your code. Instead of my
previous post - you can change:
} catch( Exception e )
TO
} catch( Throwable e )
NullPointerExceptions and other exceptions are not caught by Exception
but they are caught by Throwable, which is the lowest level.
Failing that - do wrap the entire page in the snippet I provided. If the
snippet you provided was the ENTIRE page - then my wrapping the entire
page suggestion is useless. (I am not accustomed to very short JSP pages)

Not sure about the step they called dsp though, not in your instructions. I moved copied the missing jni_md.h file into the same directory as the jni.h file and then ran ant from the /jk/native directory and it finished OK. Then I cd to /jk/native and ran ant again (all ant native in the /jk/build.xml file does is run these 2 build.xml file anyway). It failed massively, lots of missing header files, I am not sure if this is because the Mandrake instal of Apache 1.3.23 is not a full one, but as I don't need to support it I assume it is OK. I then went to copy the build jar files to the /var/tomcat4/server/lib directory where I found the tomcat-coyote.jar. The tomcat-jk2.jar is smaller than the incumbent by 1K and the tomcat-jk.jar is 21.2k compared to the incumbent's 64.1KB. I assume this is because mine does not have support for Apache 1.3? Anyway I left the incumbents there. Now I get the problem in the apache2 error_log where it says there is no worker file of worker file.

NullPointerExceptions and other exceptions are not caught by Exception

Failing that - do wrap the entire page in the snippet I provided. If the
snippet you provided was the ENTIRE page - then my wrapping the entire
page suggestion is useless. (I am not accustomed to very short JSP pages)

1. you want me put another try over this block?

if it's optione 1 then doing that doesn't help. This exeception is
comming from the code generated by tomcat. It doesn't even seem to get
to my code. If an exception is generated by my code then I should have
caught it and not the exception handler code generated by tomcat.
Another question is, is this a bug in tomcat? Initially I was more
inclined to believe that it was my code but it seems that somehow tomcat
is screwing up.

The stacktrace will show where the REAL error occured and you can follow
it from there. Currently the error is being wrapped by multiple
ServletExceptions and the error handler(by tomcat) isn't logging deep
enough. (I think)

RE: HOW TO: How do I allocate memory in JVM for extra virtual hosts
There are several things you can do (on 1.3.1 and after): 1. Make sure your global and local class parms are explicitly set to null after the work is being completed 2. Heavily used classes should provide their own finalize methods 3. You will need to call JVM to run finalization and recommend JVM to run the GC. (System.runFinalization() and System.gc() ). However, be very careful with these methods since specially System.runFinalization() might clean up the objects that you still need. 4. Use -server option for HotSpot since it's GC is much better than regular GC 5. If all above does not work, then try using java.lang.ref.Reference package to explicitly define your reference types so they would easily be collected by the GC (weak references, unreachable object etc.) 6. do NOT set Xmx and Xms to same value 7. Look at -XX options of the JVM and do more reading abouts eden, young, old generations.

By default, we use 64M for one host but adding another 64M for second host seems excessive considering it's the same tomcat instance. However, if we add a lot the JVM will use more memory before garbage collection and we've seen a 30 second (!!!) delay when using 1G Ram on JVM as it just kept using memory until it ran out. It then had almost 1G of ram to garbage collect. How can I force garbage collection to be more aggressive and do it more often when garbage is small enough not to cause a problem?

war not being fully unpacked
Hi guys, I'm deploying a war from ANT using the Catalina ant tasks. It seems that the only things being unpacked are the classes.

Howto configure mod_jk2/apache2/virtual Hosts/mod_rewrite
Hi I switched my servlet environment from apache 1.3.24/tomcat 4.0.4/mod_jk to apache 2.0.42/tomcat4.1.10/mod_jk2.

Re: What Java Profile tool do you use?
I've used OptimizeIt and JProbe. For each, I've configured tomcat like a normal app. They both are able to use Tomcat as a web app container to debug your web app, but I'm not sure why I should have done that.

AW: Questions about Tomcat/Servlets
Just answering 2: Only JSP's are compiled automagically from .jsp to .java to .class. (Note that the step to create .java is implementation specific, a jsp engine could also directly produce the class file) Servlets (that are not generated from jsp files) are not compiled automagically.

Running class finalize method when stopping/restarting a WebApp
Hi, I have an application scope class that is managing an Oracle connection cache to my database. The finalize method of this class is written to terminate all connections and close the connection cache. However, when I stop the webapp or restart it (using the manager app) the finalize of this class is not run everytime (about1 in every 3 times it does run), furthermore it seems to me that Tomcat is keeping a reference to the class as the garbage collector never closes it and Oracle DCD cannot terminate the connection as it thinks it is still alive. Can anyone tell me how to ensure the finalize method is run everytime the webapp is stopped/restarted or if there is any other way of doing the same thing ? Thanks in advance, Eddie

Re: Help Urgently needed, Security problem
Hey Rick, Man ur da BOMB, yes it work!. Thanks a lot. Now its back to da labs to see my baby(tomcat), be right back with more quetions thanks bro Edward Rick Fincher wrote:Hi Ed, You have a couple of problems. First, you left out the user data constraint transport guarantee tag that forces Tomcat to use HTTPS. A security constraint has to have 3 things: 1- the web resource collection describing what to protect, 2- the authorization constraint describing who gets access, and 3- the user data constraint telling how to protect it at the transport level. Since you mentioned that you set up port 8443 I presume you want to use secure HTTP, so the transport guarantee has to be set to CONFIDENTIAL. Use NONE for no encryption or INTEGRAL to prevent changes in data but not necessarily to prevent observation of the data during transport. One note: Port 8443 isn't the default HTTPS port. It is the default in Tomcat so that you can do development without interfering with the production port. If you don't change this to 443 you'll have to put the port number (8443) in your web address to access this webapp. One other thing that might cause a problem in your web.xml file: you had your login config out of order. It comes before security role. Some parsers are picky about that. The order from the servlet 2.3 specification is: distributable?, context-param*, filter*, filter-mapping*, listener*, servlet*, servlet-mapping*, session-config?, mimemapping*, welcome-file-list?, error-page*, taglib*, resourceenv- ref*, resource-ref*, security-constraint*, login-config?, security-role*, env-entry*, ejb-ref*, ejb-local-ref*) A corrected web.xml file is below.

Tomcat killing SuSE?
Hello there, I wanted to share some of my trouble with the people on this list. maybe some of you knows a way out of it. 1) I am using Tomcat 3.2.4, IBM JDK 1.3, Apache 1.3.x and mod_jk. All of these are pretty much unchanged and come from YaST/SuSE 7.3 on an Intel system. 2) My Application is relying heavily on XSL (xalan 2.1.0), Dom (xerces 2.0.2), JDom and all those. They all came with Turbine 2.2 b3 and I am using that. Problem 1: when accessing the site through Apache and mod_jk, URL rewriting didn't work. That is, session tracking didn't work. URLs got rewritten, but tomcat didn't recognize the browser coming back and assigned a new session. Solution to 1: on one of my other servers I had a self-compiled mod_jk, that did the job. If you ever need a reason to not trust SuSE and their packages and distribution contact me, i'll give you plenty. Problem 2: my servers once in a while stop. Yes, they do, stop entirely. Can such a thing be blamed on a Java application? Lets say one without a memory leak? Are there known pitfalls in the interplay: JVM, Apache, Tomcat (also Xalan, Xerces, etc.) that can crash the entire operation system? This happened on a machine that had been running for monthS without any failure. The apache there was serving many applications, but this was the first Java app. No solution to that one so far and help greatly appreciated!

Re: Tomcat 4.1.12 memory leak, resources leak, what to do ?
I'm running stress testing right now on 4.1.12 with jdk1.4.0. I see no memory leak problems with a real webapp that uses a ton of jstl tags. I've run it with both -Xmx128 and without. I'm guessing the culprit is something else. one suggestion is to run a super simple stand alone java program and have it run for 30 minutes. If you see a memory leak, then you know the problem isn't with tomcat. if you haven't tried running a java program with verbose GC, you really should consider trying that to see if any patterns emerge. If you see the same number of objects garbaged, but the heap grows steadily that is normal. On the other hand, if the number of objects garbaged is low and decreases with time, then you know there's a leak some place. the problem is only going to solved if you put in real effort to help diagnose it. peter Ing.

AW: Tomcat 4.1.12 memory leak, resources leak, what to do ?

(the one that comes right after you have installed tomcat) Sorry for the capital letters above, I would like to say that 1) I understand the GC concept and heap, BUT there is something wrong if reloading the same page eats all the ram. 2) Thanks to everybody that are tryng to help, BUT please read the mail before posting a reply. 3) Is there one that does NOT have my same problem by doing EXACTLY what I am doing ?

New Release JK 1.2.0 not installing
Hi, In desperation at not having a working setup and problems with mod_jk I thought it cannot get worse and may even get better if I install the latest release from RPM (what luxury not having to build it!). Anyway it tells me that I need Apache 2.0.42. If I run /usr/local/apache2/apachectl status it tells me I DO have 2.0.42. So how do I get PAckage Manager to detect that it is 2.0.42?

Unfortunately, to search any faq messages at jGuru you have to become member at 14.95 a month or 149.95 a year. That doesn't seem very Opensource like to me, just to read through some emails people are writing back and forth to each other. I would love to see some decent faq and email archive searching facilities housed at the Apache site. I know mail archives exist in gz form at Jakarta. It seems upto the project head to decide which offsite facility ends up providing indexing/search tools across those archives. Often times I find the List-serv Archive searching tools very limited for sites devoted to such objectives. That is, there's no advanced search options. How about showcasing some of these great Servlet Engine, JSP tags, Database Interfaces, Native XML DB's and Indexing tools developed through Apache by using them on site to supply great interfaces for accessing the email archives?! IDEAIt could even be released as a WebApplication project in Jakarta that others could download and install for thier email list services.../IDEA Plus, most of the documentation on how things really work ends up in email messages. Having a decent search facility is integral to reducing the amount of repeat questioning going on in the list-srvs. -Mark Diggory Michael P.

RE: New Release JK 1.2.0 not installing
All due respect to the RPM managers, but I honestly, truly feel that you can get up and running much quicker without using RPMs, and just using the Tomcat binary install and a connector binary. I'm not bragging, but I can do a Tomcat+connector install on RedHat now almost quicker than an RPM could do it...it's that easy. Tomcat is so self-contained, I find it difficult to understand the need for an RPM at all, unless it is because the RPM creates a new user (tomcat4) and adds some startup scripts to /etc/init.d (does it even do that much?). Try a binary install of Tomcat, not an RPM. Here are the steps, on any Linux: - download Tomcat - unpack Tomcat - symlink /usr/local/tomcat to /usr/local/jakarta-tomcat-some-version - set CATALINA_HOME (or is it TOMCAT_HOME now in 4.1.12?) - make sure JAVA_HOME is set - stick the mod_jk binary in /path/to/apache/modules - edit httpd.conf with JK directives or use auto-conf - start Tomcat - start Apache It's essentially fool-proof, in my experience, anyway. I have no experience with Mandrake, but I can't see how it would break a binary install. Note that the steps above have Tomcat running as root, and that adding start-on-boot scripts to /etc/init.d has to be done manually.

Anyway it tells me that I need Apache 2.0.42. If I run /usr/local/apache2/apachectl status it tells me I DO have 2.0.42. So how do I get PAckage Manager to detect that it is 2.0.42? What mechanism does it use to determine what version is installed? Mandrake 8.2 distro Thanks David Wynter Director roamware Ltd. (+44) (0) 208 922 7539 B. (+44) (0) 7879 605 706 M.

Re: New Release JK 1.2.0 not installing
You should use rpm for Apache 2.0.42 only if you got such rpm. They are available at : http://ftp.falsehope.com/home/gomez/apache2/ You could use the source rpm to rebuild it on your MDK box. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: Integrating Apache 1.3 / Tomcat 4.12 on Redhat Linux 7.3
Hi John, wich connector do you recommend to connect Tomcat with Apache (I haven't seen in your howto)? Thank you Marc Turner, John wrote: http://www.johnturner.com/howto/apache1-tomcat404-howto.html It's for Tomcat 4.0.4, but that shouldn't make too much of a difference. If you use it and have suggestions for changes specific to tomcat 4.1.12, let me know and I will update it and credit you with the changes. Also, it uses mod_jk, not mod_jk2. Whether you use mod_jk or mod_jk2 is up to you. To answer your question about auto-config, you do this by adding Listener elements to server.xml (see Connector Step 3 in my HOWTO).

Re: AW: Tomcat 4.1.12 memory leak, resources leak, final call ?
Hi, don't worry about that. It's just that top doesn't show exactly what's going on inside the VM. It WON'T crash your machine. When tomcat hits the limit of the amount of memory allocatted to it, it'll stop increase. It's not a bug. If you want to know how much memory Java is using, Nathan Meyers [EMAIL PROTECTED] suggests this approach: My recommendation is to stop trying to make sense of the output from top and ps, and go to an unambiguous source. Take a look at the contents of /proc/pid/status, where pid is the process ID. This will, at any instant you examine it, give you (among other things) total current VM usage and RSS.

What happens during a gc is just that inside the vm the memory is marked as free. So the only save indicators for the question 'how many memory is currently in use' are the methods java.lang.Runtime.get*Memory. - To a certain degree it is normal that the memory is increasing. Reasons for that: - each session needs some memory, that is only released after the session has timed out. If you create sessions very fast this can consume quite some memory. (If you are creating the sessions faster as they dye tomcat will die with an out of memory error.) - Just because an object isn't used anymore , is dosn't mean that the memory that is consumed by it is freed. This just happens, when the garbage collector runs. When this will happen, is up to the VM. Until then the memory will grow. There is nothing you (or tomcat) can do about that from inside the application. The only action that has affect, is to play with the various parameters for the garbage collector as argument to the java process. So what can you do, to track the problem down: - Make shure that the request don't create new sessions. (There are several routes how to achieve that) - Strip the page that you test down to a minmal jsp. (I haven't seen in your previous posts that you say anything about the nature of this page) - Track the memory usage with java.lang.Runtime.get*Memory() - Use the java options to achieve a verbose gc - Set the maximal heap size to a lower bound, to see what happens when this value is reached. - Profile the application with OptimizeIt or jProbe or any other profiler. - show us your page, maybe it's the page that contains the memory leak Sun has some background and advice at: http://java.sun.com/docs/hotspot/gc/ http://java.sun.com/products/hotspot/whitepaper.html Also javaworld: http://www.javaworld.com/javaworld/jw-01-2002/jw-0111-hotspotgc.html Ralph Einfeldt Uptime Internet Solution Center GmbH Hamburg, Germany Hosting, Content Management, Java Consulting http://www.uptime-isc.de -Ursprüngliche Nachricht- Von: Ing.

How many people are using 4.1.12 successfully?
Hello - We're almost ready to deploy a new app. We have been using 4.0.4 in development. I need to get an idea of how stable 4.1.12 is...based on the traffic in the last week, 4.1.12 looks to be fairly unstable, regardless of its 'release' designation. Should we stick with 4.0.4, or take the plunge with 4.1.12?

RE: New Release JK 1.2.0 not installing
RPM is a good solution when you need package, ie when you have to clone configuration on site with many boxes. the mod_jk 1.2.0 rpms also setup httpd.conf and that's important for newbies and beginers. Experienced users could still use the good old configure/make system : ./configure --with-apxs=/usr/sbin/apxs make Voila the jk is compiled, not so hard ?

RE: Tomcat 4.1.12 memory leak, resources leak, what to do ?
Hi, In any case, did any of you tried what I did ? Yes. As well as having tried substantially more refined, QC'ed, regulated stress testing of various JDK / Tomcat / OS combinations for memory and other resources leaks. If you have not, then please do not comment.. People are trying to help you out. It's completely voluntary and at their own time / expense. A nicer attitude is likelier to get responses. As far as I see this IS a problem. I disagree. The memory will never decrease without a garbage collection. You have to play with other stuff (limit session creation, limit processing threads, etc) and even then you'd be hard-pressed to keep the memory constant with ongoing page retrievals. P.S. Asking for help at bugzilla had no effect. Yes it did. People looked at it and feel it's not a bug. If you still think it's a bug, submit a patch. That's what open-source is all about.
