mass virtual hosting with rewrite
I am running Apache 2 with Tomcat 5.5. Both are working fine and hosting about 200 domain names. The problem is that every time a new domain is added I have to edit server.xml file and restart tomcat. With Apache I am using RewriteMap files so I just edit those files and no need to restart it. I wanted to run it by you guys and see if anyone tried using Rewrite to avoid setting up virtual hosts in Tomcat server.xml file. Basically have Rewrite conditions in Apache say user1.com http://user1.com rewrite to localhost/user1 user25.com http://user25.com rewrite to localhost/user25 This way Tomcat doesn't have to be setup with all those virtual domain names. Any idea how to do it? Of course I would not want the URL to change in the browser address bar so the rewrite would have to be internal only. What do you think? Thanks Oleg

Re: Calculating required memory
Thank you very much for your input gentlemen. Increasing PermGen is a great idea, because I do see my server giving me out of memory permgen error at least twice a day and now it makes sense why, I was thinking my -Xmx settings 1024m should take care of my needs for now and that was wrong, I set MaxPermSize=256m and the server seem to be fine for now, keeping my fingers crossed. Now regarding shared/lib directory I thought that every application loads its own copy of those libraries, but if its only one time load and since all my applications are identical copies (only data changes) I might as well move all my classes into shared, before I only had struts, hibernate jars and so on That wouldnt create any thread safety issues would it? Thanks again for your time, this helps a lot!

Would I be correct to estimate that Tomcat will atleast need n(number of users/applications) * mb(total size of shared/lib) As Chuck has already pointed out, no (but I'm going to try a slightly different angle on it :-) ). Each class that is loaded from shared/lib will be loaded by the Shared classloader, so you'll only have one copy of the class in your JVM. Jars are compressed, so the sizes of the loaded classes will be larger than the bytes occupied on disk; but not all of the classes from a jar will be loaded, so the sizes will probably be smaller. Note, however, that any classes in the webapp's WEB-INF/lib *will* be loaded once per webapp. If you have large numbers of applications, you may want to put more common libraries in shared/lib, and you may also wish to increase the size of the permanent generation (PermGen) in the JVM's memory model as this is where the classes are stored. Your per-session and per-page data will dwarf the space required for classes; and, as Chuck pointed out, the only way to find out these sizes is to profile the app. This will also make sure that you're not going to fall foul of any other performance limits, such as CPU use or disk bandwidth. - Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: virtual host memory usage
Oh I see, well actually what I do, since all users with virtual hosts running identical applications, I place all application related libraries in shared/lib and WEB-INF/lib has only one jar which is application itself and its not in shared or common, common/lib only has Tomcat5 libraries plus database driver jar since I am using JNDI.

virtual host memory usage
Why running 100 virutal hosts in Tomcat takes up much more memory than running a 100 identical applications under one host? Is there a way to configure Tomcat to run both the same? Thank you Oleg
Virtual hosts and shared libraries
I got a problem with Tomcat using a huge amount of memory on startup. Of course I realize that it all depends on how large are the applications. However, I have lets say two identical machines with Tomcat 5.5 installed. One Tomcat has 100 virtual hosts running the same application and takes up 400MB of ram after it finished loading, second Tomcat has 300 identical applications but deployed under localhost and it uses only 200MB of ram after loading. Can somebody explain me what is the case here? Does it mean that virtual hosts load all libraries in shared directory for every host into memory but all application running under localhost, simply load them once? I am a bit lost, I need to figure something out to cut down on memory use, any ideas? All users are running same application, application specific classes are in its own application WEB-INF/classes and all libraries needed to run the application, like struts and hibernate and so on are in shared. Thank you.
multiple contexts
Hi, I am running Tomcat 5.0.28. Our setup is somewhat similar to Virtual hosting company. When a new user signs up, user's site is accessible through localhost.com/user1 and after user registers the domain name site is also available through user1.com. My problem is that it seem to be double the load, each application is deployed twice. 1. Application is deployed by adding a user1.xml file to conf/Catalina/localhost for localhost.com/user1 2. Application is deployed for domain name bu adding user1.xml to conf/Catalina/localhost.com/ and making appropriate changes to server.xml file for a virtual host Is there a better way to do it? to allow user access to a website both ways but having the application deploy only once and somehow having pointers to it?

Correct -- the per-webapp classloader is the child of the shared/lib classloader. (This is an oversimplification but please bear with me.) Really, there are more than two classloaders involved, forming several parent/child relationships in a hierarchy... Try to think of it as the GoF Chain of Responsiblity pattern: when the per-webapp classloader can't find a class, it delegates (passes the request) to its parent. This keeps going until you hit a classloader that can successfully load the class, or until the innermost classloader -- which doesn't delegate to anyone else -- gives up and says there's no such class. Going the other way thus isn't possible: that innermost (parent) classloader can't see what its children see, and so on. If a class under shared/lib needs access to (depends on) a class in a child classloader, it will never find it, and the system throws a NoClassDefFoundError. It's for a similar reason one webapp can't see another webapp's classes: they only have a relationship with their parent classloader, and not that of their siblings. -QM - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
out of memory when there is plenty
Windows 2003 Tomcat 5.0.28 Ok I searched and searched endless and still cannot understand what the problem in my case. Ok, I understand that there can be a leak in teh code and thats why Tomcat runs out of memory. However, the server got total 2GB Ram memory, Tomcat is set to use min 512, max 1024. When I start getting an out of memory error, Tomcat5 in task manager shows anywhere 350MB to 390MB, I run a script on the server to check Runtime and it shows that memeory usage is very low compared to max/min settings and there are about 600MB available.

I know question was asked many times and I have read a lot of posts people asking how to add a virtual host without restarting tomcat and the answer, not possible. So I am wondering, is it because its time expencive that tomcat doesnt check virtual hosts names real time, or atleast refreshes the list stored in memory.

Re: outOfMemory exception under high load
Just a thought, I was having the same problem using JNDI for database connection. Our database pool was going crazy due to a lot of connections left unterminated and database memory usage was enormous. Restarting Tomcat would only help for a day or two and than OutOfMemory errors would come up again. Restarting the database, gave us several weeks until the error started coming up again once the memory used by database grew. Thinking that it had something to do with the memory it took to maintain the pool.

All solutions I've seen include apache, handling static pages and usual apache stuff + machine with tomcat, handling JSP's and servlets. Is it possible to store JSP's on the server where apache is running? It's just a matter of convenience - it would be nice to upload the whole site with JSPs and have it running without remembering that you should upload all JSPs to some special place on a second server.

It was working perfectly in Tomcat 4.1.24 but it works in Tomcat 5.0.4 only in half: When user tries to access protected page he is presented with login page. If he enters valid login/password then he receives access to the resourse. But if the user enters invalid login/password then instead of form-error-page Tomcat displays HTTP Status 405 - HTTP method POST is not supported by this URL error with URL http://myhost.here/j_security_check;.

Please help save Tomcat for a high profile project in Switzerland: Problem compiling mod_webapp for IBM HTTP Server 1.9.19 running on AIX 4.3.3.
My insufficient knowledge of AIX platforms prevents me from successfully compiling mod_webapp (as well mod_jk) on AIX 4.3.3 platform. Hardware: IBM pSeries 660 model 6H1 OS: AIX 4.3.3 (not sure about exact maintenance level) Web server: IBM HTTP Server 1.3.19 Servlet Engine: Tomcat 4.0.1 Tools libraries: IBM's port of common GNU other open-source packages available at http://www-1.ibm.com/servers/aix/products/aixos/linux/download.html Tomcat itself appears to be running flawlessly. Unfortunately due to my poor knowledge of AIX I have been so far unable to recompile neither mod_webapp nor mod_jk for the specified platform. Actually compilation worked fine in both cases. What did fail was the 'ld' linker. As far as I can judge about possible cause of failure, the linker requires a module export (.exp) file in order to be able successfully complete linking process. In this respect AIX appears to differ from Unixes, as I had no problems at all building mod_webapp mod_jk under Linux (Mandrake 8.0 Mandrake 8.1) as well as Solaris 8. The problem is aggravated by the management's desire to use IBM HTTP Server instead of plain Apache mainly due to IBM's SSL support, which is perceived to be more secure. Is my assumption right? If yes, is there a way I could generate that damn .exp file for mod_webapp or somehow do without it? Has anyone ever succeeded in compiling mod_webapp for IBM HTTP Server on AIX 4.3.3? I have been informed by the management that if problem is not resolved by mid next week Tomcat will be replaced with WebSphere 3.5 Standard Edition. :((( Please help save Tomcat for the project. Our work is highly visible. The system will serve population of an entire Swiss canton. If successful the system may be adopted by other cantons with Tomcat prominently featured alongside some leading commercial products.

Re: about the IIS (in win2000 professtional version) and tomcat installing
Hello Mermaid, Yes, it can work with Win2K Pro. 1) Install location of ISAPIfilter DLL in registry in the following place: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W3SVC\Parameters\ FilterDLL=d:\jakarta-tomcat-3.2.1\bin\win32\isapi_redirect.dll 2) create virtual dir. "jakata" - point it to the same place. 3) restart IIS Oleg L. SverdlovWeb Development Dept.

Re: Stuck Combining Servlets and JavaScript
- Original Message -
Frank, I can think of conventional techniques:
1) add new Javascript section:
script language="javascript" src="/servlet/generatearray"/script
generatearray.class must produce MIME type for Javascript.
2) if the main file is HTML, try to use SHTML:
script language="javascript"
!--#include virtual="/servlet/generatearraydefinition" --
for(var k=0;ktitle.length;++k) document.write("p"+title[k]);
/script
actual syntax of the include depends on your webserver.
and so on...

Subject: Stuck Combining Servlets and JavaScript
I have a servlet that can generate JavaScript arrays. I want to
combine those arrays with html/javascript for final presentation.
One of the catches is that the servlet uses an HttpSession to
keep track of what has happened.
So, say I have an html file containing this (less headers):
script language="javascript"
booktitle = new Array("title1","title2","title3","title4");
for(var k=0;ktitle.length;++k) document.write("p"+title[k]);
/script
So, I want the servlet to generate the second line of the script.

I read all previous messages in the list with the term "memory" in it, but everything i try does not help. problem: the memory consumption of the java.exe increases slightly, the over all memory consumption of the system increases fast and memory is not released. after a week (and about 400 hits or so) the server runs out of memory (tomcat gives a OutOfMemoryError and quits). what i did: - set java max heap size (nothing changed) - set max_threads (30), max_spare_threads(20) and min_spare_threads(5) for both http and https ConnectionHandler - set session-timeout to 1 Minute - added System.gc() to end of every servlet my application uses servlets and mysql, i close every mysql connection and i am not able to find anything i could change to get the memory freed. I also use ms-stresstool and i can simulate this memory-problem. could anyone give me some assistance please? thanks, Gerd

[Windows 2000] Is that Tomcat eating memory ?
Hello. The machine runs Tomcat 3.2.1 + jdk 1.3 + iis_redirect + Win2K Professional Every time a browser reloads a page, "Java" process eats out a few bytes of memory. Simple hello.jsp consumes a few bytes. Pages dealing with Java beans or db connections, consume more memory. On Win2K Server, I can see that memory pool of "Java" process does NOT grow, whereas "inetinfo" process eats out a few bytes of memory with every request. In the same time, iis_redirect.log contains following entries: [jk_isapi_plugin.c (261)]: jk_ws_service_t::start_response, ServerSupportFunction failed [jk_ajp13_worker.c (314)]: Error ajp13_process_callback - start_response failed [jk_isapi_plugin.c (554)]: HttpExtensionProc error, service() failed [jk_isapi_plugin.c (355)]: jk_ws_service_t::write, WriteClient failed [jk_ajp13_worker.c (325)]: Error ajp13_process_callback - write failed [jk_isapi_plugin.c (554)]: HttpExtensionProc error, service() failed Anybody know anything about this problem?

Once those puppies are loaded, them will be up all the time. Next thing is to refer from JSP pages to those poppies, such as getValue(email), and dbmanager will return it...
