Possible thread deadlocking in 3.2.2 beta 5?
Hello, I have an app I just ported to Tomcat 3.2.2 beta 5 that runs fine for a while, and then begins to run slower and slower until it dies. From looking at the log files, it appears that 3.2.2 beta 5 is thread deadlocking and thus running out of resources. The log file shows Full thread dump... sections where you can see the JVM is having problems releasing threads. The really weird thing is that this is not a high volume server. It received no more than 300 hits over the period of a week. However, that was enough traffic to kill it. I have the same exact app running on another machine under 3.2.1 with no problems. If you look at the log file on the 3.2.1 machine, there are no Full thread dump... errors and the app has been up for months. Thus, something appears to have changed between these versions that is affecting my app's thread usage. There are a few environmental differences between the two implementations of Tomcat. I have 3.2.2 beta 5 on a quad processor WinNT 4 Sp6a machine w/128mb allocated to Tomcat. 3.2.1 runs on a single processor Win2K server w/64mb allocated to Tomcat. Could the multi-processor server be a factor? Both servers are using Sun JDK 1.2.2. Since the log file to 3.2.2 beta 5 is so big, I have posted it to the URL : http://www.poptarantula.com/logs/jvm.stderr_5_22_01.txt Does any one have any idea what could be causing this behavior? Are there any known fixes? Thank you in advance for your help. Best regards, Joel Kozlow [EMAIL PROTECTED]

RE: Thread deadlocking in 3.2.2 beta 5?
Hello Marc, You and I think alike :). I have already upgraded the single processor Server to 3.2.2 beta 5. I ran a battery of tests at it to simulate heavy load. So far, there are no thread deadlocking errors reported. Thus, I think you are correct in your assessment that this may have something to do with a multi-processor server. However, before we go too far down this road, I thought I would see if any one else is running Tomcat on a multi-processor box with NT 4? I would also be happy to help out in diagnosing this problem. Again, if we confirm that no one else has really tested a multi-processor environment, I can take the following steps: * Install Tomcat 3.2.2 beta 5 on a development server * Run the product with debug logging * If necessary, run the entire server in a JBuilder debug session * Provide any test results that you request Please let me know how I may be of further assistance. Thank you again for your help.

Using = 150 CustomTags on a JSP breaks the VM for all Tomcats (4.0b5/3.2.2b3-b5)
Hi all, I'm facing a showstopper for further usage of tomcat. Placing a lot (=150) custom tags on a JSP brings down the VM on Win-platforms (Win2k and NT4.0 latest SP) (Tested with JDK1.3 and JDK1.3.1 (beta)) The creation of the corresponding java file (from the JSP) and the compilation to the class-file seems to work, but the execution breaks. The error message is: # # HotSpot Virtual Machine Error, Internal Error # Please report this error at # http://java.sun.com/cgi-bin/bugreport.cgi # # Error ID: 47454E45524154452F4F502D41500E435050084B # # Problematic Thread: prio=5 tid=0x8ebd470 nid=0x54c runnable # The same JSP works fine under JRUN3.1 (SP2). I'm attaching the war with the test case. It contains the JSP (TagTest.jsp). The tag which is used in this JSP is the html:Img-Tag from the Struts project (1.0 b2). Actually the problem is related to any custom-tags. I've used the one from Struts, just to be sure that the problem is not related to my tags. Any help will be wellcome, Thanks, fm
RE: Using = 150 CustomTags on a JSP breaks the VM for all Tomcats (4.0b5/3.2.2b3-b5)
Sorry about this, but the war-file is 100k; can't attach it as stated. I'm attaching the JSP. It requires the struts.jar and the struts-html.tld to work (actually to not work :( Regards, fm TagTest.jsp TagTest.jsp
JSP Naming Standards ?
Are there recognised naming standards for JSP's ? If I have a customer login page for Company ABC should I call it. ABC_Customer_Login or abc_cutomer_login or abccustomerlogin or abcCustomerLogin or what ? Please could you give me a reference to the standard, as I only want to change everything once ! Thanks David

Tomcat vs. Other App Servers
Hi, I have been working with Tomcat for a few months now with little problems. I am wondering if this app server is ready for prime time when it comes to business end of the things. What do the other servers that cost upwards of $1 offer that Tomcat doesn't? Also, I have been hearing a lot about Caucho's Resin Servlet engine as another open source alternative? Anyone have any takes on the app server market? Thanks Curtis

But When i start service use net start "service name" Error happens like following : The TomcatService service is starting.The TomcatService service could not be started.

debugging of jsp's
Just dreaming load here; How would it be possible to write a debugger for jsp's that interpreted a jsp page, and made the content of the pageContext available with a nice gui? I know this is all possible to retrieve by attaching a debugger to tomcat, but this gives me a strickly servlet view, not a jsp page view. Being able to toggle between the jsp and the generated code at debug time would also be nice.. -- - Torgeir

Anyways, if you're inside a webapp (another servlet in the same context), use RequestDispatcher.forward(); if it's a remote URL, use sendRedirect. POST data should be resent too. Un saludo, Alex.

tomcat4 / apache 1.3.x integration problem
Hello! Like some others I have a problem with connecting the tomcat 4 (beta 4 or 5) with the apache 1.3.19. The computer is a solaris 8 (sparc) system with jdk1.3 and a gcc compiler I could successfully compile a mod_webapp.so file. Although after copying it to the apache/libexec folder and running apachectl configtest I get the error: libapr.so.0: symbol __eprintf: referenced symbol not found Can anyone help me with this error message? For compiling the mod_webapp.so I had to compile the apr package from apache. My guess is, that I don't have the matching version of it. On http://apr.apache.org/ I just go tthe latest snapshot apr_20010523060225.tar.gz Is this a good one? Is there somewhere a ready distribution tar? And which one works with tomcat4.

Re: Tomcat vs. Other App Servers
Well, this is interesting I've raised this issue many times around me and it always becomes a philisophical debate on open-source and stuff like "is open-source compatible with a companies needs" etc I've also discussed this with one of the guys working on the Orion app server. And I wrote a paper on this for a conference in my university. First of all, you need to take into perspective a few points : Tomcat is NOT an application server, it cannot run EJB, it is not built on a J2EE model, you can't deploy beans and such Tomcat isservlet engine, it processes JSP and servlets. Now, let's talk about "web*" app servers, like websphere and weblogic. Both these products cost thousands of dollars, $10k as you put it is not including services offered by IBM or BEA, the manufacturers. Both these products are very heavy, and DO NOT run well on a i386 architectures compared to when they run on 64 bit machines, like Solaris Sparc machines. (I've used weblogic on a sunblade in a production environment and it runs nicely). Websphere is a security nightmare, you can crah it by telnetting garbage to it on port 8009 (if i remember corrrectly) So choosing a server depends on your needs. Application Architecture : Apparently, you don't need a J2EE architecture, since you've been working with tomcat for a while. Tomcat can suit you well. Costs : If youcan't affordservices, a 30 000 $ server, $10 000 for weblogic or websphere, go with tomcat. Performances : On a pentium architecture, tomcat runs a million times faster. The architecture I like (and recommend my customers) is Apache with mod_jserv and Tomcat, on a linux box, on a dual-pentium 3 server. Why dual proc ? Memory leaks =) Apache is the most widely used web server out there, it has nothing to prove, it is secure and administrable, performant etc... It runs better than all its expensive competitors. So it comes down now to politics, if someone somewhere in the process refuses to rely on open source software, go with the bigshots, and don't hesitate to buy services and support (not necessarily from the manufacturer), you'll gain alot of time and money in the long run. The arguments against using open-source are usually the following : * We don't get support : false, many small start-ups offer consulting and support for less than the big shots, and you get support from the community for free (like on this list) * It can get discontinued without warning : inexact : the Apache foundation has been around for longer than most dotcoms, and doesn't show signs of weaknesses.

Also, I have been hearing a lot about Caucho's Resin Servlet engine as another open source alternative? Anyone have any takes on the app server market? Thanks Curtis

Multiple contexts under IIS on different virtual hosts.
I'm trying to get multiple contexts on the same machine, under different hosts. To explain what I'm trying to do: Let's say I have a machine called HAL. I have two sites hosted on it, let's call them www.site1.com and www.site2.com. I want to have a Tomcat context on each, let's say /foo, so that requests to www.site1.com/foo/xxx.jsp and www.site2.com/foo/xxx.jsp will be redirected to Tomcat. I'm not sure about the way to set up IIS so that this will happen...do I set up the jakarta filter and virtual dir on Default Web Site, or do I put these on each virtual web site in IIS? And if so, do I have to name them uniquely? Or do I have to do something even weirder, like have Tomcat set up in different directories. Maybe I'm doing something really dumb, but I just can't figure out what is going on, as I can't get this to work. Thanks, Sean
lb-problem with mod_jk: high cpu load on apache when tomcat breaks down
Hello tomcat-users, We are having a problem with mod_jk and load balancing. Does anyone else have had similar problems with that kind of architecture setup? Our System: === Alteon switch (round robin) | | three Apache 1.3.19 on three SPARC-Servers (called s1,s2,s3)(3 CPU, 3 GB) | |each: mod_jk with lb (in case of s1: 1*s1,0.001*s2,0.001*s3) | | | two tomcats-3.2.1 on each server (jdk1.2.2, native threads, -Xms50M -Xoss4M -Xss4M -Xmx600M) We chose this architecture because the alteon is not able to perform session tracking properly. The Problem: On startup, the system works fine. Each java-Process has about 1-8% CPU load. After one day or so, one tomcat takes 40% CPU load or more. I think the reason is inside our applications. But thats not the error I want to post: After the error of a tomcat, the httpd-processes on EACH Server begin to take a lot of CPU time (8-30% each). In server-status I can see that the processes are waiting for a response of that tomcat. Of course I want to have a fault tolerance, but when I have a problem with one server, the other servers go down too. Did/Does anyone have the same problem and/or a similar system architecture? Maybe anyone solved that problem?

Re: Multiple requests
So, just to clarify: The request arrives, Tomcat processes it and sends it to your servlet.

problem to handle sessions with Tomcat
Hello Here I face a problem with Apache1.3.14+Tomcat3.2.1 . I am building up a login module in which the process flows like: login.jsp--LoginServlet--login_success.jsp. In the servlet , on the successful login , i am initiating a session and putting some values. But I am not able to get back the same vakues in the login_success.jsp. In fact the session id of the session initiated in the servlet and the same of the session retrieved in jsp are different. I have tested the code in JavaWebserver2.0 and also in the same Tomcat-Apache environment at some other place.In both the case the problem did not arise. So i guess in my environmental set up , i missed out some configuration. But nobody yet able to point out exactly what configuration is missing and what is the remedy. I am using JDK1.2.2 on WIN2K and Oracle8i. The problem persists even after complete reinstallation of everything. If somebody already faced it and knows the solution, please help me as soon as possible. Regards and best wishes Sibendu
RE: Apache and remote tomcat server
We got this working by replicating the tomcat directory structure on the apache box. the reason for this lies somewhere in the way MOD_DIR and AUTO_INDEXING work. A good example of what i mean follows for the below to work you would have to have a /test directory on you apache server. even if you did not have any data in it. When mod_dir checks to see if a directory exists it does not for some reason transverse accross the plugin but only the local filesystem based upon your DOC_ROOT directory. On you tomcat server you would create a directory called test inside the ROOT directory of jakarta-tomcat /usr/local/jakarta-tomcat/webapps/ROOT/test This is where you JSP's would go. You will also need to modify you workers.properties file and put a copy of it on the apache server. the particular line that is important for this is the host line. It is set by default to be "localhost" change it to the machine that is your tomcat server. IfModule mod_jk.c JkWorkersFile /usr/local/apache/conf/workers.properties JkLogFile logs/jk.log JkLogLevel warn JkMount /*.jsp ajpB12 JkMount /test/servlet/* ajpB12 JkMount /test/*.jsp ajpB12 Alias /test "/usr/local/jakarta-tomcat/webapps/test" Directory "/usr/local/jakarta-tomcat/webXpps/test" Options Indexes FollowSymLinks /Directory Alias /test "/usr/local/jakarta-tomcat/webapps/ROOT/test" Directory "/usr/local/jakarta-tomcat/webXpps/ROOT" Options Indexes FollowSymLinks /Directory /IfModule This is the only way we have found that allow mod_jk to work correctly with tomcat and apache. if some else on this list has gotten this to work, possibly a more correct way please post it to the list. If this is the correct way please let me know i have not been able to find ANY documentation pertaining to the setup of mod_jk using remote workers.

Which connector is correct for Tomcat4b5 Apache 1.3.19 ?
When using Tomcat 4b5, which "connector" is the one that I should use to
connect
Tomcat with Apache 1.3.19 for WinNT4? I have looked extensively through
documentation
and archives but cannot determine which connector to use.
The server.xml file that comes with Tomcat4b5 has this quoted reference:
"The MOD_WEBAPP connector is used to connect Apache 1.3 with Tomcat 4.0
as its servlet container. This is built by following these steps:
- cd {TOMCAT-SRC-HOME}/connectors
- make
- (Edit "Makedefs" as needed for your installation)
- make
- su root
- cp connectors/apache-1.3/mod_webapp.so {APACHE_HOME}/libexec
- exit
To configure the Apache side, you must ensure that you have a
"ServerName" directive defined in "httpd.conf". Then, lines like
these to the bottom of your "httpd.conf" file:
LoadModule webapp_module libexec/mod_webapp.so
WebAppConnection warpConnection warp localhost:8008
WebAppMount examples warpConnection /examples/
Finally, modify the "defaultHost" attribute in the "Engine" directive
below to match the "ServerName" setting defined in "https.conf". The
next time you restart Apache (after restarting Tomcat, if needed)
the connection will be established, and all applications you make
visible via "WebAppMount" directives can be accessed through Apache.
"
From what I gather from this comment, mod_webapp is what the authors of
Catalina
want me to use, especially since mod_webapp is the only connector in the
src.
Also, this message in the release notes:
"
MOD_WEBAPP Connector:
"
"A new version of the Apache 1.3 side of the MOD_WEBAPP connector is
included
in this release, in the "connectors" directory. It has not been tested
heavily yet, so it should be considered experimental."
Yet I see many references within the mail list regarding
mod_jk or mod_jserv, and almost nothing regarding mod_webapp.
Is anyone using it?
Is there some documentation site on mod_webapp that I can visit?
(I found nothing about it one the Jakarta web site.)
Any *gotchas* with regards to this?
I would deeply appreciate any experience or insights that users might have.
Thanks in advance.

How to fix ClassCastException in Windows
When trying to execute Tomcat4.0-b5 from DOS, I received ClassCastExceptions. After searching the mail, I saw someone mention that classes loaded by different classloaders are treated as different classes even though the names may match. I made the following changes to 'catalina.bat' and it works now. 1) Explicitly added every .jar or directory to source/.class to classpath defined in catalina.bat 2) Changed the start class from org.apache.catalina.startup.BootStrap to org.apache.catalina.startup.Catalina 3) No .jar files in magic directories server/lib or common/lib.

RE: Basic Doubt
Try making a request just like you would on port 8080, something like: http://Hostname:80/vitualroot/servlet/Servletname The way it works is, when Tomcat stars up, it recreates it's mod_jk.conf file each time. It puts in there all the subdirectories that are under it's webapps directory as virtual directories. Thus if you want to access the file: /%tomcat_home%/webapps/testsite/index.html through Apache and Tomcat you would make the request to: http://Hostname/testsite/index.html Because inside the mod_jk.conf there is redirector on the path testsite that passes that request to Tomcat. See if that works.

But if you make a request directly to 8080 it will be Tomcat that answers, not Apache. Try making the same request on port 80 and see what happens.

JSP to Servlet Loosing Session Info
I noticed some posts about people having problems loosing the session information when using JSPs with servlets. For examples if I did the following in a JSP: FORM ACTION=/servlet/com.mycom.MyServlet ... when MyServlet got control, the Session was empty. I found out that if I did this the right way and defined the servlet in my web.xml, e.g., servlet servlet-nametheServlet/servlet-name servlet-classcom.mycom.MyServlet/servlet-class /servlet servlet-mapping servlet-nametheServlet/servlet-name url-patternsomeServlet/url-pattern /servlet-mapping and in the JSP said: FORM ACTION=someServlet ... then all worked fine. You may have to adjust the path a bit depending upon where your JSP is, etc. The Tomcat mapping trace can help you debug mapping problems. This seems like it is a Tomcat bug, but the above is not only a workaround, but a more maintainable way of doing things. Frank Lawlor Athens Group, Inc.

I'd be interested to know if you can duplicate the deadlock problem on your system using the stuff from the examples webapp? -Original Message- From: Joel Kozlow [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 22, 2001 6:58 PM To: '[EMAIL PROTECTED]' Subject: RE: Thread deadlocking in 3.2.2 beta 5? Hello Marc, You and I think alike :). I have already upgraded the single processor Server to 3.2.2 beta 5. I ran a battery of tests at it to simulate heavy load. So far, there are no thread deadlocking errors reported. Thus, I think you are correct in your assessment that this may have something to do with a multi-processor server. However, before we go too far down this road, I thought I would see if any one else is running Tomcat on a multi-processor box with NT 4? I would also be happy to help out in diagnosing this problem. Again, if we confirm that no one else has really tested a multi-processor environment, I can take the following steps: * Install Tomcat 3.2.2 beta 5 on a development server * Run the product with debug logging * If necessary, run the entire server in a JBuilder debug session * Provide any test results that you request Please let me know how I may be of further assistance.

Hello, I have an app I just ported to Tomcat 3.2.2 beta 5 that runs fine for a while, and then begins to run slower and slower until it dies. From looking at the log files, it appears that 3.2.2 beta 5 is thread deadlocking and thus running out of resources. The log file shows Full thread dump... sections where you can see the JVM is having problems releasing threads. The really weird thing is that this is not a high volume server. It received no more than 300 hits over the period of a week. However, that was enough traffic to kill it. I have the same exact app running on another machine under 3.2.1 with no problems. If you look at the log file on the 3.2.1 machine, there are no Full thread dump... errors and the app has been up for months. Thus, something appears to have changed between these versions that is affecting my app's thread usage. There are a few environmental differences between the two implementations of Tomcat. I have 3.2.2 beta 5 on a quad processor WinNT 4 Sp6a machine w/128mb allocated to Tomcat. 3.2.1 runs on a single processor Win2K server w/64mb allocated to Tomcat. Could the multi-processor server be a factor? Both servers are using Sun JDK 1.2.2. Since the log file to 3.2.2 beta 5 is so big, I have posted it to the URL : http://www.poptarantula.com/logs/jvm.stderr_5_22_01.txt Does any one have any idea what could be causing this behavior? Are there any known fixes? Thank you in advance for your help. Best regards, Joel Kozlow [EMAIL PROTECTED] Sn. Developer Hewtlett-Packard

Repost: AdaptiveClassLoader problems with Tomcat 3.2.1, IIS and Struts web apps
I have not seen any responses on this so I'm trying again: I have two struts-based web apps installed under a single instance of Tomcat (Struts Beta 1, Tomcat 3.2.1 connected to IIS 4.0 on Windows NT via isapi_redirect.dll). They are defined within server.xml as follows: Context path=/cdl docBase=d:/projects/cdl crossContext=false debug=1 reloadable=true trusted=false /Context Context path=/enroll docBase=d:/projects/benefits_enrollment crossContext=false debug=1 reloadable=true trusted=false /Context Accessing the first web application is fine. The problem that I am having is that any attempt to access start.do on the second web application (/enroll), the server log returns: 2001-05-08 10:51:10 - path=/enroll :action: Error creating ActionForm instance of class 'com.globalmedic.benefits.enrollment.forms.login.LoginForm' - java.lang.ClassNotFoundException: com.globalmedic.benefits.enrollment.forms.login.LoginForm at org.apache.tomcat.loader.AdaptiveClassLoader.loadClass(AdaptiveClassLoader.j ava:524) at java.lang.ClassLoader.loadClass(ClassLoader.java:253) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:313) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:120) at org.apache.struts.action.ActionServlet.processActionForm(ActionServlet.java: 1645) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1520) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:491) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.tomcat.core.ServletWrapper.doService(ServletWrapper.java:404) at org.apache.tomcat.core.Handler.service(Handler.java:286) at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java:372) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:79 7) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:743) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(HttpC onnectionHandler.java:210) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java:416) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:498) at java.lang.Thread.run(Thread.java:484) It seems as if it is attempting to load classes within the context of the first web application. If I reverse the order of the context definitions in server.xml, I will have a similar problem with the /cdl app. I have verified the following: - struts.jar exists only in the WEB-INF/lib directory of each web application - tomcat.log verifies that the web.xml of each application is being read I have tried setting up different AJP12 workers to service each application but that seems to have no effect. I have also noticed that the jasper.log shows Classpath according to the servlet engine referring only to one of the two web apps. Is it possible to have two web apps running in a single instance of Tomcat? Have I overlooked something? I did not have any problems hosting multiple web apps using with JRun...

Re: How to use Tomkat with apache.
Bonjourno! I managed to get tomcat working on my computer, here is what I did. 1) Make sure you have JDK 1.3 installed on your computer (to verify, type in java -version) In order to make JDK 1.3 run properly on RedHat 7.1, in your /etc/profile file put in a line saying: ulimit -s 2000 also, make sure that the following files exist: /usr/bin/expr /usr/bin/dirname /usr/bin/cut /usr/bin/head Those files are used by the java script that launches the actual JVM. For instance, on my computer, my java 1.3 sdk is installed at /usr/j2sdk1_3_0 so if I type in more /usr/j2sdk1_3_0/bin/java it shows the shell script used to launch the JVM. 2) download the tomcat binaries (3.2.1 is the latest non-beta) 3) unzip the tomcat binaries somewhere appropriate For example: on my computer I put tomcat in /usr/local/jakarta-tomcat-3.2.1 4) edit the startup script(s) in the bin subdirectory of your tomcat installation on my computer: /usr/local/jakarta-tomcat-3.2.1/bin 5) launch tomcat and have fun!

Aliasing urls in Tomcat (without using Apache)
Hi guys, During development we would like to use Tomcat locally without having an Apache front end, then only have an Apache front end proxy passing to Tomcat when it goes into production. We are running into problems with how to replicate the proxy pass functionality of Apache in Tomcat. Eg say we have a context of /context and in its base directory there was a subdirectory called my_directory. To get rid of the context out of the url in Apache for the public site we would just do the following proxy pass proxypass /my_directory http://localhost:8080/context/my_directory where localhost:8080 is of course picked up by Tomcat. This would mean the url would look like http://mydomain.com/my_directory - much tidier than http://mydomain.com/context/my_directory We cannot work out how to set up a similar arrangement in Tomcat. Note: we are *not* asking how to make context=my_directory, so we can't just add another context my_directory that maps through to the same base directory as context. Any ideas people?

If you just want the request object (the parameters) to be passed call the servlet2 with the request object and finish what you're doing and the request object is gong after that. Simple. You can also create an hashtable in the session with those values from the request object and delete the hashtable from the session when you're finished, this way you can use a redirect to the next servlet, so people don't have to resubmit the request on a refresh..

export TOMCAT_HOME=/usr/local/tomcat
i then typed in the following (from bash) from the tomcat/bin directory:
./startup
some messages appeared on the screen, then bash appeared to hang (it didn't
return to the prompt after a few minutes). i didn't get a tomcat.log file
so i can't figure out what went wrong. can someone please help me

Install problems in FreeBSD 4.2
Hi, I recently downloaded and installed jdk1.3.0_02 on a FreeBSD system. I followed the instructions included with the jakarta-tomcat README which indicated that I needed to set an environment variable of JAVA_HOME=/usr/local/jdk1.3.0_02 and add $JAVA_HOME/bin to the PATH. The instructions indicate that I should set the CLASSPATH if needed, but I do not know if it is needed, or what it should be set to. When I try to run ./bootstrap.sh for jakarta-ant (install instructions for tomcat say it is next step in setup of tomcat) I get: /usr/local/jdk1.3.0_02/bin/java: /usr/bin/expr: not found Error: can't find libjava.so. The same messages pops up if I try to run ./build.sh for tomcat without first installing ant. The jdk was installed from j2sdk-1_3_1-linux-i386.bin. How do I get past this error message to the next error message? I have been unable to find documentation for setting this up in FreeBSD, so if someone can point me in the direction of some, I would greatly appreciate it. Thanks.

RE: 3.2.1 Dies
I can't say I know FOR SURE that the threads were dead, but after a considerable length of time they never accumulated any more CPU usage time (as seen via top or ps) whereas some of the others did. I know for sure I had far more threads than the max_threads setting (12 for me) because I'd see in excess of 80 threads for tomcat on the system after several days uptime. I might try upping the max_threads to see if that helps. We were trying to limit concurrent usage of the box (via tomcat) because other apps use the same box and we didn't want to use too many resources. That said, we'd rather have a stable tomcat and overload the box a bit on occasion :) than an unstable/really slow tomcat. -Devon Devon C.

It seems to me that when tomcat (3.2.1) get's pressed for thread resources, it doesn't do a very good job of recovering from this.

That said, I seem to lose threads with tomcat 3.2.1 on Linux 2.2.14 using Sun's 1.3 JDK. What I mean is that dead threads pile up WELL in excess of the thread pool limit. These threads don't seem to handle requests any more. Tomcat slows down quite noticeably too. I'm not sure I have ever left it up long enough to know if it might just die after enough threads pile up(well, it definitely would when it hit the OS' thread limit).

Re: Install problems in FreeBSD 4.2
That's a jdk configuration problem, not a tomcat problem. If you can successfully get run a simple command like: java -version then you can move on to the tomcat-related stuff. I've never gotten jdk 1.3 to work in BSD, but you should make sure that the following files exist: /usr/bin/expr /usr/bin/dirname /usr/bin/cut /usr/bin/head If they exist somewhere else (eg. /bin/cut ) then copy them to the expected location (or link them) Hope this helps! -Mike Jennings - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, May 23, 2001 2:33 PM Subject: Install problems in FreeBSD 4.2 Hi, I recently downloaded and installed jdk1.3.0_02 on a FreeBSD system.

Re: mod_jk is garbled? Garbled? I got the binary...
I had the same problem and, definetely, you have to build your own mod_jk.so. Try downloading another version of Apache (not installing it)and use it's apxs. I have 1.3.19 and it works fine, only follow the mod_jk page instructions: Make sure you have Perl 5 installed. The apxs script used to build the module is written in Perl. Change directory to jakarta-tomcat/src/native/apache1.3 (or apache2.0). Run the apxs command that came with your apache distribution (hint: look in /usr/local/apache/bin, /usr/sbin, or wherever you intalled apache). Type the command all on one line. For Linux: apxs -o mod_jk.so -I../jk -I/usr/local/jdk/include - I/usr/local/jdk/include/linux -c *.c ../jk/*.c Your build may fail because the object files from the ../jk directory have been compiled to the current directory, rather than their source directory. Running gcc -shared -o mod_jk.so *.o should finish the build. Good luck! Renato Upgraded Apache to 1.3.20, got Tomcat 3.2.1. Downloaded binary of mod_jk, but when it tries to load it I get: Starting httpd: Syntax error on line 8 of /usr/local/tomcat/conf/mod_jk_set.conf: API module structure `jk_module' in file /usr/local/apache/libexec/mod_jk.so is garbled - perhaps this is not an Apache module DSO? What's the deal with that? Any ideas? Tried compiling myself, but apxs dies at the end. I got it from the linux dir, and I'm running Redhat 7.0 Thanks.. --

Subject: NT problem : Tomcat service stops when user logs out of NT
I know this is in the archives somewhere but I cannot find it.
Is there a problem when running the Tomcat wrapper jk_nt_service.exe with JDK/JRE 1.3?
If I remember correctly, the problem is that if you start the service and then you
log out of NT, the service is shutdown. And, supposedly, this is not a problem when
using JDK/JRE 1.3.
If this is indeed a problem, are there any suggestions as to how to run tomcat as a
service in the JDK/JRE 1.3 environment? Has anyone had luck with the JavaService app?
