Re: Re: mod_jk: ajp13: cpu load problem with apache
First of all thank you for your interest. I will download the latest code and try this out. I do have the debug mode enabled so I will sent you any errors (although I have not noticed anything special). I don't think though that I can reproduce the problem myself. About the gdb, I have no experience of how to attach to the process but I will do my best to find a colleague that does. Thanks, Costas Can you try the CVS head, and see if it still happens ? If so, can you give us more details that would allow to reproduce it ? Messages like 'it doesn't work for me, you figure out why' are not very helpfull. At least enable the debug messages, let it run until it hungs, then maybe trim the log and send the last entries. Or use gdb to attach to the problem process and do a stack trace.

I have two tomcat engines and I use the lb worker of mod_jk to balance user request to these two engines. The problem is that some httpd processes seem to go into some cpu performance tasks and start consuming all the cpu of the machine (2processors, 2GB mem). After some time almost all available CPU is consumed by the apache processes. If I kill the child processes that cause the problem, the load falls back to normal. At the same time, I notice that I have excessive CPU usage in one of the tomcat instances. The problem keeps recurring all the time (almost every hour). I read in the mail-archives about similar problems but I didn't find a good answer. The version of mod_jk is the one in jakarta-tomcat-connectors-4.0.2.01 I compiled the source on the same machine (aix). I have to say that I have noticed similar problems on many more apache installations that have similar installations (apache, lb + 2 or more tomcat engines) with older versions of mod_jk and tomcat. Actually, the above problem makes the lb worker unusable since I cannot trust the setup in my production environment. Please, any idea or patches or whatever will be very helpful.

digested passwords: using RealmBase.Digest() in a jsp
Hi Folks, please help me out of this one... I´ve set up a tomcat with JDBC Realm Authentication and MD5 Digest. So far, it works fine, but I somehow don´t manage to use the Method org.apache.catalina.realm.RealmBase.Digest() in one of my JSPs. I need this Feature to let my Users change their passwords via web. This works well when implemented as Standalone Application. I just can´t import this class in my JSPs. The reason is that I can´t include catalina.jar in my classpath - tomcat won´t start when I do.

web application using implementation Sun's JSSE
Hi all, I have following configuration: 1. Local Web server: * A web application written using JSP 1.2 * IBM Java SDK 1.3 (for Linux) * Tomcat 4 * Sun's JSSE 1.0.2 (as an SSL Implementation) 2. Remote Web Server * Black box with a servlet which accepts requests via HTTPS The local web application generates a document (in XML) which needs to send a HTTPS POST request to the remote web server for processing. I have written a class which does this using JSSE. The class works fine standalone outside Tomcat and successfully posts the document to the remote web server. I have installed JSSE jar file JAVA_HOME/lib/ext However when trying to use the class from within a JSP web application I receive 'SSL Implemention Not Available'. Most help on web is on how to use JSSE for HTTPS enabling Tomcat, however I am not doing this, my web application is acting as an HTTPS client.

How to add a throw exception to a servlet
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
The doPost method of a servlet looks like this :
public class selectdetail extends HttpServlet {
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
What if in my doPost method I am using Object methods that throw other
exceptions, like SQLException. The Java compiler would not let me write :
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException,SQLException
But I want the exception to be caught in the error.jsp page, not do a try
{...} catch{...} inside the doPost body.
I don't know if I explained it correctly but is there a simple solution to
this problem ?

Well, it sounds like you are running on some flavor of unix. I've set up tomcat servers on solaris and linux. For Solaris you can put the startup script in /etc/rc2.d or /etc/rc3.d. If you run on Linux. I found you need to put it in /etc/rc5.d. If you don't use linux, don't worry about rc5.d. The commands I've put in the top of the tomcat.sh are to set environment variables. An alternative would be write your own script that sets the variables, then calls tomcat.sh (forwarding the commandline arguments). That way, tomcat.sh won't be altered.

following in the standard 'and here's one I made earlier' line here's one that works - really rather well ! Install it in /etc/rc.d/init.d then ( if you have linux ) run chkconfig --add tomcat or if you use some other unix varient see what run level you are running at ( have a look in inittab ) and then cd to /etc/rc.d/rcx.d ln -s /etc/rc.d/init.d/tomcat . if you don't have the /etc/rc.d directory you can miss that bit out ... this will run Tomcat as the user tomcat - so you might want to add that user or change it ...

RE: Which Connector for Tomcat 4.0.3 - mod_webapp or mod_jk
For example, mod_jk won't know that we want Tomcat to process a filter chain against a directory unless we've done a JkMount for that tree, whereas it would know that Tomcat needs to process a JSP page. On the other hand, mod_webapp would know about the filter chain because the resources would have been deployed as part of a web app. This isn't quite true. You can get the same functionality with mod_jk as mod_webapp by saying: JkMount /mycontext ajp13 JkMount /mycontext/* ajp13 that works *exactly* the same as: WebAppDeploy mycontext warpConnection /mycontext/ Which part of unless we've done a JkMount for that tree didn't you understand? I did not say that mod_jk doesn't support the facility, just that it has to be configured properly. Your example provides exactly what I said would be necessary. Having done this, Tomcat will serve up even static resources in that context. Which is what the deployment is asking for in this case. --- Noel -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]

Tomcat 4 Configuration help needed!!!
Hi all. I am in need of the help of a clever soul from this list. I have a tomcat 4 running a major web application based on struts and several internal developed classes, which needs to assume some control of the virtual hosting on the server. See in our application we have a framework based on a filter which needs to do something like this: http://www.tse.dk/tse/do/login should really be redirected to the resource at: http://www.tse.dk/do/login, but only if the tse part of the URL is present otherwise it is a errorneous URL in the context of the application. Now we achieve this through a Servlet 2.3 Filter which puts a wrapper around the ServletRequest to ensure proper routing happens. This is all an exercise to allow for one web application to host many virtual companies without needing to actually do any kind of installing on the server for each company we host for. Now the problem is I have all the code running, however when the URL is '/tse/do/login' instead of '/do/login' then our filter doesn't get called. We have a context mapping in servlet.xml, which maps the '/' context to our webapplication, and that works, however when we do '/tse/' it seems that Tomcat goes off looking for other webapplications instead of mapping it to ours correctly. I hope somebody here can tell me how to keep Tomcat from doing that. To make Tomcat map all stuff coming in after the hostname to be mapped to our webapplication instead of anything else.

RE: A bit off topic
You can't do it directly, but using a loop and JavaScript's literal initializer you can create the JS code to do it. (Note: this is not the most efficient way to do it, you should use a StringBuffer to build the variable.) String jsVar = [ + array[0]; for (int i = 1; i array.length; i++) jsVar = jsVar + , + array[i]; out.println(var jsArray = + jsVar + ];; There is nothing special to do on the client side. Just make sure the line is output within the HEAD section of the page and your array (called jsArray) will be declared and populated when the page is loaded in the browser. -Original Message- From: Richard Johnstone [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 02, 2002 9:02 AM To: [EMAIL PROTECTED] Subject: A bit off topic I know this is a bit off topic but I can't seem to get an answer from anywhere.

Could'nt connect to X11 window server
Greetings everybody,
The list administrator may please pardon
me for my earlier excesses. I was
repeatedly getting [EMAIL PROTECTED]
so I had to resort to messages like the
earlier one.
To begin with I may mention that I am
posting this question here because the
JServ list has been discontinued (the last
posting was on March of last year!). Tomcat
is a servlet engine closely modelled on JServ
so any trouble that JServ comes up with can
be handled by the masters of Tomcat.
So this is my setup, I have Apache JServ 1.1.2
configured to run with Apache 1.3.19 on a Mandrake
7.2 with the X11 window server installed and running.
I compiled the following servlet and placed it in
the servlets folder of JServ:
public class OpenFrame extends HttpServlet implements SingleThreadModel
{
public void doGet(Http..request req, ..response res) throws
{
set content type text/html
PrintWriter out=res.getWriter();
out.println(htmlheadtitle);
out.println(THIS SERVLET ALSO OPENS A AWT FRAME);
out.println(/titlebodyOPENING FRAMEbr/);
try
{
java.awt.Frame fram=new java.awt.Frame(FRAME TITLE);
set the frame size...
set the frame background color
set the frame foreground color
fram.show();
}
catch(Exception e)
{
out.println(+e);
}
out.println(/body/html);
out.close();
}
}
Its compiling successfully. I ran the Apache
server on the Mandrake machine and from another
Windows machine I opened OpenFram. I got an
Internal Server 500 error. I checked the JServ
logs:
Can't connect to X11 window server using ' 0:0'
as the value of the DISPLAY variable
I ran a google search to find out what this
error means and I came across this post:
http://java.apache.org/faq/fom-serve/cache/73.html
After reading this post I came to the
conclusion that JServ WAS TRYING TO LOAD AND OPEN
THE FRAME ON THE MANDRAKE MACHINE, despite the
request coming from the Windows machine.
The frame should open in the Windows machine.
What is happening here? I am in the process
of disabling my X11 window server but still
this is the strangest thing I ever came across.

mod_jk performance optimization
Hi. I've got installed in my box Linux, Apache 1.3.19, JDK 1.3.1 and TC 3.3.1 working with ajp13. The following error appeard in my mod_jk.log after a bit of continuous utilisation: [jk_ajp13_worker.c (203)]: connection_tcp_get_message: Error - jk_tcp_socket_recvfull failed [jk_ajp13_worker.c (621)]: Error reading request After analysing the server's config files and reading some threads, I concluded that the problem might be resolved through a bit of extra re-configuration. Although the problem appearence was delayed, it still existed. I wonder if anyone out there could help me with this subject. I'm sending in attach some lines of httpd.conf, server.xml and mod_jk.conf Thanx a lot for your time. Serrano. ## ## httpd.conf -- Apache HTTP server configuration file ## # # Timeout: The number of seconds before receives and sends time out. # Timeout 300 # # KeepAlive: Whether or not to allow persistent connections (more than # one request per connection). Set to Off to deactivate. # KeepAlive On # # MaxKeepAliveRequests: The maximum number of requests to allow # during a persistent connection. Set to 0 to allow an unlimited amount. # We recommend you leave this number high, for maximum performance. # MaxKeepAliveRequests 100 # # KeepAliveTimeout: Number of seconds to wait for the next request from the # same client on the same connection. # KeepAliveTimeout 15 # # Server-pool size regulation. Rather than making you guess how many # server processes you need, Apache dynamically adapts to the load it # sees --- that is, it tries to maintain enough server processes to # handle the current load, plus a few spare servers to handle transient # load spikes (e.g., multiple simultaneous requests from a single # Netscape browser). # # It does this by periodically checking how many servers are waiting # for a request. If there are fewer than MinSpareServers, it creates # a new spare. If there are more than MaxSpareServers, some of the # spares die off. The default values are probably OK for most sites. # MinSpareServers 5 MaxSpareServers 10 # # Number of servers to start initially --- should be a reasonable ballpark # figure. # StartServers 8 # # Limit on total number of servers running, i.e., limit on the number # of clients who can simultaneously connect --- if this limit is ever # reached, clients will be LOCKED OUT, so it should NOT BE SET TOO LOW. # It is intended mainly as a brake to keep a runaway server from taking # the system with it as it spirals down... # MaxClients 150 # # MaxRequestsPerChild: the number of requests each child process is # allowed to process before the child dies. The child will exit so # as to avoid problems after prolonged use when Apache (and maybe the # libraries it uses) leak memory or other resources. On most systems, this # isn't really needed, but a few (such as Solaris) do have notable leaks # in the libraries. For these platforms, set to something like 1 # or so; a setting of 0 means unlimited. # # NOTE: This value does not include keepalive requests after the initial # request per connection.

java.lang.IllegalAccessException
Hi list, I'm having a very odd problem with tomcat 3.3.1 on windows today, suddenly, and for no apparent reason, tomcat's classloader is having problems accessing (public) methods in any of my beans. All the code I'm working on has been running fine for over a month. here's the stacktrace: javax.servlet.ServletException: Cannot create bean of class DbUtilities at index_10._jspService(index_10.java:80) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:119) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at org.apache.tomcat.facade.ServletHandler.doService(ServletHandler.java:574) at org.apache.tomcat.core.Handler.invoke(Handler.java:322) at org.apache.tomcat.core.Handler.service(Handler.java:235) at org.apache.tomcat.facade.ServletHandler.service(ServletHandler.java:485) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:917) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:833) at org.apache.tomcat.modules.server.Http10Interceptor.processConnection(Http10Interceptor.java:176) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:494) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:516) at java.lang.Thread.run(Thread.java:536) Root cause: java.lang.ClassNotFoundException: class DbUtilities : java.lang.IllegalAccessException: Class java.beans.Beans can not access a member of class DbUtilities with modifiers public at java.beans.Beans.instantiate(Beans.java:208) at java.beans.Beans.instantiate(Beans.java:48) at index_10._jspService(index_10.java:78) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:119) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at org.apache.tomcat.facade.ServletHandler.doService(ServletHandler.java:574) at org.apache.tomcat.core.Handler.invoke(Handler.java:322) at org.apache.tomcat.core.Handler.service(Handler.java:235) at org.apache.tomcat.facade.ServletHandler.service(ServletHandler.java:485) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:917) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:833) at org.apache.tomcat.modules.server.Http10Interceptor.processConnection(Http10Interceptor.java:176) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:494) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:516) at java.lang.Thread.run(Thread.java:536) In this instance the bean in question is DBUtilities, but I get the same result for all other beans in any of the web apps I'm running. I found this on sun's site regarding the IllegalAccessException: Thrown when an application tries to load in a class through its string name using: The forName method in class Class. The findSystemClass method in class ClassLoader. The loadClass method in class ClassLoader. but the currently executing method does not have access to the definition of the specified class, because the class is not public and in another package. None of these cases are relevant, especially since up until an hour ago teh code had been running fine, and the ClassLoader was fiding my beans without any problems. The directory in which the beans are stored (mywebapp\web-inf\classes) is in my classpath, hte beans arn't packaged (this is tomcat 3x). The class in question is imported into a jsp via a jsp:Usebean tag. As I said, this is now happenning with all my beans in all my webapps. All have the correct public no-argument consrtuctors. I havn't changed anything in my tomcat config. Previously the code was running fine. Posts regarding this Exception in the archive seem to be mainly package or JNDI related, not the case here.

Re: How to redirect the log file from the command window to a file?
you still have output on the console because you redirect the standard output to your file (see the ' %ACTION%-server.log' ?) the remaining output is most surely the error output which you might also want to redirect to your file i don't know the windows command for linux, i add '21' before the classic redirect that tells the system to redirect the second output (ie the error output) to the 1st output (ie the standard output) somepath/mycommand 21 someotherpath/mylogfile you can also separate the files somepath/mycommand 2 someotherpath/errorlog someotherpath/standardlog another solution would be to tell java that System.out and System.err must be redirected to a file see java.lang.System javadoc, i know there is a setter for both streams something like System.setOut(new java.io.FileWriter(somepath/somefile); System.setErr(new java.io.FileWriter(somepath/someotherfile); bye David - Original Message - From: Louis Voo [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Thursday, May 02, 2002 3:21 PM Subject: Re: How to redirect the log file from the command window to a file?

Re: OutofMemoryError
We have figured this out, although for the life of me I can't understand why. We had been running with java -server -Xms128m -Xmx256m -Xincgc and saw the VM climb way up to 2GB, then drop the tomcat process. By removing the -server flag, everything is fine. I realise this means that the JVM is defaulting to 'client'... so I guess is anyone aware of memory holes in the 1.3.1 JVM on linux? I've dug around deja c and seen a few references to this suspicion but nothing concrete. I'm going to start working on Tomcat 4 and jdk1.4.0 in my lab this morning, hopefully the problem is fixed in 1.4.0! Thanks for all the responses!

[ ... ] I haven't been very active on the tomcat-user list for a while, but I do recall that the list owner (if there ever even really was one, i.e. a human one) was not very responsive -- I sent mail to them a number of times, and I don't think I ever got a response. Regarding unsubscribing, I think the biggest problem (but not necessarily the only one) has to do with trying to unsubscribe from a different address than the one you're subscribed as. That is, when you subscribed, it was as a certain address -- if you didn't explicitly set it, it was from wherever you sent the subscribe message. But perhaps because of moves, address changes, machine changes, etc., you are no longer at that address (but because of forwards/aliases, you still receive mail sent to that address). So, if you try the simple unsubscribe method (i.e. without specifying an address), the address you send it from won't match the subscribed address, and the list won't accept it. The simple unsubscribe method is to send a message to [EMAIL PROTECTED] The trick is to tell it what address you are subscribed as when you try to unsubscribe. Of course, you have to know what address you are subscribed as before you can do that. The way to find that out is to look for a header on a message from the list that contains that information. On my setup (using Pine on a UNIX system), I can look at the From line (not From:) or the Return-Path: line. There'll I'll see something like: [EMAIL PROTECTED] The 18383 is the message number, and the mepstein=uiuc.edu is the address I'm subscribed as (with the @ changed to a =). Now that you have that info, you can include it with your unsubscribe request. To do that, instead of sending a message to [EMAIL PROTECTED], send it to [EMAIL PROTECTED], where name=domain.com (or rather [EMAIL PROTECTED]) is the subscribed address. BTW, the necessary header info to get your subscribed address is available with Outlook -- you may have to click in a certain place and/or set some options, but it is there, it's been mentioned on the list before.

Re: java.lang.IllegalAccessException
we'll, I've looked a little further into my problem. It turns out that its only within this webapp's context I'm getting the error (sorry - should have checked further the first time). I reinstalled my most recent backup of the webapp and it found the beans ok. I didn't alter the code in any of the jsp pages or the beans today, so the Import Routine servlet timing out in my browser seems to have somehow caused the error. However, if I simply copy over the webapp which is having trouble by copying the folder with all its contents and giving the folder a different name and restart tomcat, so creating a new webapp, I still have the same ClassLoader problem. It might be relevant that just prior to this problem appearing I ran a servlet which imports a (quite large) tab delimited file into a mysql db table. My machine appeared to run out of memory before completing the operation and I got the default IE 'dns' error screen. After this, I had problems trying to instantiate beans within this context. tomcat restarts and full machine restarts have no effect.

I would like to use Tomcat for the web-based remote-control of the system, as a Java-Servlet application. i.e I would like start/stop a Linux process from a remote PC's browser and collect data on Real-Time. Browser-Tomcat -GateServlet Spawn a process on Linux. Is it possible to execute a Linux Shell's Script-file via GateServlet? If so, please let me know how to do it. Or, does it need to get-out of Tomcat, and we have to rely on some Inter-Process communication between Tomcat(as a Linux process) and the other Linux processes?

OutOfMemoryError and static pages
hi, I'm experiencing memory problems with Tomcat as a Standalone Server. (this must have popped up somewhere before, but I could not find it in the bugbase or mailing archives.) I see the problem under those settings: Linux / Sun JVM 1.2.2_06 / Tomcat 4.0.1 rel. Linux / Sun JVM 1.4.0 / Tomcat 4.1 current cvs My application dynamically creates (lots of) jpg files in a webapp's subdir. The client(s) access these (HTTP/GET) once. after that, the jpg is useless and gets deleted after a certain amount of time. Each GET consumes a considerable amount of memory (around 12k) within Tomcat which is not freed until Tomcat is shut down. Running my stress test application (which was intended for stressing _my_ application) results in a Tomcat uptime of less than five hours with max heap I can do on this box (256M). this is very bad scalability. Tomcat goes dark with trace logs like those attached at the end of my email. It appears (but is not measured) that the problem has something to do with the size of the JPGs: The bigger the JPG, the more memory is consumed at each request. I looked into the current Tomcat code and measured some things but did not find the hotspot. DefaultServlet (esp. serveResource(), copyRange()) is used everytime a JPG is loaded but it seems to be ok, the BufferedXXXStreams seem to be fine. Possible workarounds: - Access the jpgs via file-protocol - only possible on local host. but leaves Tomcat memory constant. (as expected. tomcat is doing nothing then.) - Using apache for serving the jpgs - ok, but the nasty scalability problem in Tomcat would stay, my setting would completly change. I read a brief remark in a posting (by Remy Maucherat?) that static fileserving is an issue and associated code is currently rewritten. My questions: - is this scalability issue known and is there a prospect of a fix? - can you point out the cause for my problem (i.e. where to look at in the Tomcat code or which objects eat all that memory)? - can i help out with testing as soon as a the issue is tracked down?

Using the precompiled jsps with tomcat 4.0.x
Hi, I'm using the tomcat 4.0.3 and I'm looking for the way to avoid the jsp page compilation in runtime. I was about to use the supplied jspc compiler that's included in the distribution. However I shortly found out that it generates the classnames that are different from those generated by the runtime jsp compiler. I resolved this problem by subclassing the JspC class and delegating the jsp compilation to the JspCompiler class instead of the CommandLineCompiler. As a result I have the java files with the proper names. However I don't see the good way to avoid runtime compilation. Even having the precompiled classes in the webapp's war file the Jasper doesn't use it. It looks the jsp page from the war and tries to find corresponding class in the _work_ directory that's empty initially. Therefore it involves the compilation of the source JSP. Is there any way to avoid this compilation without populating the tomcat's _work_ directory with the precompiled classes?! What's the right approach to use the JSP precompilation? I appreciate any help in this matter.

java.lang.VerifyError while using struts with Tomcat 4.0.x
Hi, I'm using tomcat 4.0.3 integrated with JBoss 2.4.4 (they run in the same JVM). Struts framework is used to handle the presentation logic. This combination works fine with Tomcat 3.x. However after I upgrated to the Tomcat 4.0.3 I'm experiencing the java.lang.VerifyError (Incompartible argument for a function) while the ActionServlet instanciates some action classes. I'm sure that the problem caused by the changes in the tomcat's classloader. I had the situation when the class with the same name is accessible by two different classloaders. I found out that the problem appears if the class is loaded by the classloader that's different with the one that the current thread uses. In this situation I had this VerifyError. I was able to resolve the problem by eliminating the class duplication, now I have no two same classes that are placed in the different jars. However the question is why this error appears? The situation that I had when the same class is accessible by multiple class loaders is not prohibited by the Java language. I'm wondering what classloader contraint was violated. To fix the problem I have to use the jar's packaging that's not very convenient for me. So I appreciate any help that allows me to resolve this problem in better way.

Re: How to add a throw exception to a servlet
You can wrap almost any exception in a ServletException and rethrow it
that way.
The ServletException class allows you to call one of four constructors:
1) no parameters
2) String
3) String, Throwable
4) Throwable
===
try{
//some code here that may throw a SQLException...
}catch(SQLException se)
throw new ServletException(se);
}finally{
//remember to close any connections here!
}
===

Re: JSP's GzippedOutputStream
I do not think so. The JSPWriter is not able to send a byte array
(something I found while trying to output a pdf 2 weeks ago...the hard
way).
It converts byte values to char values which are double bytes in java.
Your byte array may look like this {01 02 03}, but the JSPWriter sends
out something like this {01 00 02 00 03 00} instead.

Hi!
Afaik servlets may produce Gzipped template output something like
this:
...
OutputStream out1 = response.getOutputStream();
out = new PrintWriter(new GZIPOutputStream(out1), false);
response.setHeader(Content-Encoding, gzip);
.
But how we can do that with JspWriter? Is it possible to do similar
with JSP?
Re: JSP's GzippedOutputStream
You can always use mod_gzip on apache to send compressed
data... I take it you're trying to reduce your bandwidth usage ?
PS mod_gzip does very well

Does the HTTPConnector not follow the virtual hosting part of the spec
All, I appologize for asking this question again, however I haven't gotten a response and I was hoping to get some of your thoughts ... I have noticed a difference between the HttpConnector and the WarpConnector while using tomcat 4.0.2. From the 2.3 spec: SRV.3.6 Multiple Hosts and Servlet Contexts Web servers may support multiple logical hosts sharing one IP address on a server. This capability is sometimes referred to as virtual hosting. In this case, each logical host must have its own servlet context or set of servlet contexts. Servlet contexts can not be shared across virtual hosts. This seems to be true when using the WarpConnector but not true when using the HttpConnector. While using the HttpConnector on Windows I have one subdirectory under work, which is localhost. I can connect to this server from multiple host names however I always just have one directory - localhost. Static variables are also shared between hostnames. While using the WarpConnector on Linux I have multiple directories under my work directory - one for each host that I navigate to. Static variables are not shared between hostnames. I saw this article: http://faqchest.dynhost.com/prgm/tomcat-l/tmct-01/tmct-0108/tmct-010850/ tmct01082322_32599.html which looks like the user is experiencing different contexts on Linux but not on Windows - It could be because the user is using the WarpConnector on Linux but not on Windows... Has anyone had any experience with this? Thank you all for your help! I have been a reader of this list for a long time and I appreciate all of the help that I have received!

catalina.out rotation.
Hello, I have tomcat-4.0.3, solaris sparc 8. Well, as the topic says I need to know how to rotate catalina.out log file, without restarting the tomcat. It's created in bin/catalina.sh and every time catalina starts the logs are just appended to it with no rotation. The problem is that file handle is kept all the time while the tomcat is running, so moving/copying to another file and then deleting the original doesn't help. Once the next action has to be logged, the original file is becoming the same size as the copied file is + the normal log output for the action happened. Regular tricks with cp catalina.out catalina.out.backup;cat /dev/null catalina.out don't help either - same result.

Hi Ralph, Have you tried putting catalina.jar in common/lib/ or /java/jre/lib/ext/ or even WEB-INF/lib?

Upgrading to 4.1.x (I hope)
I've been looking on the Tomcat site to determine where I should download the version I desire - I see the 3.x and 4.0.x sections, but nothing for 4.1.x. Am I blind? If someone could be generous and either give me explicit navigational instrutions or (ideally) a link to the nightly builds directory, I'd be most appreciative. Currently I run 4.0.1 but want to upgrade to the 4.1.x series in order to move datasources from my apps to Tomcat. I don't want to use a 4.0.x version becasue ... well I don't =) Any information is greatly appreciated! Thanks so much! Eddie

RE: Which Connector for Tomcat 4.0.3 - mod_webapp or mod_jk
On Thu, 2 May 2002, Noel J. Bergman wrote: AIUI, mod_webapp has been easier to configure; mod_jk offers load balancing, The configuration is the same, for the 'basic' things: WebAppDeploy examples /examples is arguably as easy as: JkMount /examples/* tomcat And has the same effect (i.e. current webapp behavior ). What is complex is advanced configuration - lb, letting apache handle static resources, etc. This really is a huge difference, if I understand the implications (without reading through the code). For example, mod_jk won't know that we want Tomcat to process a filter chain against a directory unless we've done a JkMount for that tree, whereas it would know that Tomcat needs to process a JSP page. On the other hand, mod_webapp would know about the filter chain because the resources would have been deployed as part of a web app. mod_webapp will know that because it forwards all requests. Same is trivial with mod_jk, however jk does give you the option to fine tune what resources are forwarded ( and maybe use apache where an equivalent functionality exists ). One of the goals of mod_jk2 is to go further and be able to operate with only 'standard' apache directives and configuration ( i.e. Location and SetHandler ). That'll be much faster and easier to integrate - but even more verbose. However that's just one option, for advanced use.

The problem is that some httpd processes seem to go into some cpu performance tasks and start consuming all the cpu of the machine (2processors, 2GB mem). After some time almost all available CPU is consumed by the apache processes. If I kill the child processes that cause the problem, the load falls back to normal.

mod_jk.conf-auto suggests you are using a version of Tomcat 3.2.x. The generated files are not configurable in in 3.2.x. These are configurable in Tomcat 3.3.x, with slightly different defaults. The generated files for 3.3.x all default to being written to the conf/auto directory instead of into conf.

Loadbalancing....please Help!
Hello all: I´ve been struggling with this issue for quite a long time now, and I can´t seem to find a solution. I´m actually using this configuration: Apache 1.3.23 Tomcat 4.0.1 Jboss 4.2.3 I´ve used mod_jk and the loadbalancer connector to connect my web server with two other tomcat servers. Both of the tomcat servers connect to the Jboss server. The problem is that sessions are not mantained. Apache keeps sending me randomly to one tomcat server or the other instead of choosing one. That makes me lose my session id and get errors in my application. Regarding to the tomcat servers configuration, I have my jvmroute statement set right (I think): in server 1: Engine jvmRoute=tomcat1 name=Standalone defaultHost=foo.bar.com debug=1 in server 2: Engine jvmRoute=tomcat2 name=Standalone defaulttHost=foo2.bar.com debug=1 the workers.properties file has this configuration: # list the workers by name worker.list=tomcat1, tomcat2, loadbalancer # # First tomcat server # worker.tomcat1.port=8009 worker.tomcat1.host=foo.bar.com worker.tomcat1.type=ajp13# # Specifies the load balance factor when used with # a load balancing worker. # Note: # lbfactor must be 0 # Low lbfactor means less work done by the worker. worker.tomcat1.lbfactor=50 # # Second tomcat server # worker.tomcat2.port=8009 worker.tomcat2.host=foo2.bar.com worker.tomcat2.type=ajp13 # Specify the size of the open connection cache. #worker.tomcat2.cachesize # # Specifies the load balance factor when used with # a load balancing worker. # Note: # lbfactor must be 0 # Low lbfactor means less work done by the worker. worker.tomcat2.lbfactor=50 # # Load Balancer worker # # # The loadbalancer (type lb) worker performs weighted round-robin # load balancing with sticky sessions. # Note: # If a worker dies, the load balancer will check its state #once in a while. Until then all work is redirected to peer #worker. worker.loadbalancer.type=lb worker.loadbalancer.balanced_workers=tomcat1, tomcat2 # # END workers.properties # Maybe I set the lbfactor wrong? Wich numbers should I use? Thanks a lot for all your help so far. Gabriel PS: Here is a little graph of the distribution of the servers **** *Apache web server ** Tomcat2 server * *Tomcat1 server ** Jboss 2.4.3 * *foo.bar.com** foo2.bar.com * ****

Re[4]: Where do I edit /etc/tomcat4/conf/tomcat4.conf in Windows 2000? Want to edit LANG setting
Hello Tom, Well, how about here: http://www.alexandriasc.com/software/JavaService/source.html Tomcat.exe is simply a program called JavaService: JavaService is a Win32 executable that allows any Java class to be run as an NT service. It uses JNI's invocation API to create a Java Virtual Machine using any JNI compliant Java implementation. Also, the options being referred to have nothing specifically to do with Tomcat at all. They are JVM options...specifically, Sun JVM options for JDK1.3 and JDK1.4. CATALINA_OPTS = -server -Xms8m -Xmx128m 1. -server - use the server VM 2. -Xms8m - Set the initial size of the Java memory allocation pool (that is, the heap) to 8 Mbytes (The default value is 2MB) 3. -Xmx128m - Set the maximum heap size to 128 Mbytes (The default value is 64MB) 4. -Xincgc - Use incremental GC, eliminate occasional garbage-collection pauses during program execution, although 10% hit in overall GC performance The CATALINA_OPTS evironment variable is there as an convenience for you to use when running Tomcat. If you've specified this environment variable, Tomcat, using the scripts to start up, will use these flags when starting itself up. These flags tell the Sun JVM to behave in particular ways that may optimize your application running within the JVM. Does that clear things up? Jake Thursday, May 02, 2002, 1:16:48 AM, you wrote: TB Jake, Also, what is that -jvm_option? I haven't seen that before? My %CATALINA_OPTS% evironment var looks like: -server -Xms8m -Xmx128m. Should I be using -jvm_option? TB I have NO -server option. I think there is a big difference between Tomcat TB 3.x and 4.x. If you type tomcat.exe /? you will see all available options. TB It may also be a difference between Tomcat running as a service (Win$ows TB only) or running it in a shell. TB Some weeks ago I tried to find out where the source code of Tomcat.exe is, TB but nobody replied!

Hi, I suppose this question should have been answered, but I could not find a satisfactory answer in the archives. Isn't it possible to run tomcat as standalone on port 80 with a user other then root. Apache server manages to do this. But as far as I can see tomcat can not. I wonder why? Can someone answer? This ability of tomcat would have been great since we did not need neither apache nor mod_jk, etc. Also since apache and mod_jk are written in C it troubles many people to get them run on different platforms. So I do not understand why tomcat do not have the ability run on port 80 with a user other than root. Thanks in advance.

Re: R: what is needed to connect to mysql
Hello Gianluca,
Or use:
Thread.currentThread().getContextClassLoader().loadClass(dbDriver);
Instead of:
Class.forName(dbDriver);
The latter won't find the driver if it isn't immediately within the
same classloader as the class calling Class.forName where the first
one will find it in parent classloaders, so you can have the driver in
$TOMCAT_HOME/lib or $TOMCAT_HOME/common/lib...or WEB-INF/lib if you
still want to do that.
