Well, my JNDI name for the resource is jdbc/gatep5 and that is what I have as the ResourceParams name=jdbc/gatep5.

Jakarta/tomcat crashing with MySQL
Hi all, I have recently been facing a strange problem. Tomcat has been going down along with MySQL and I can't find any log entries for this. Tomcat is configured to use the mysql database for user and group verification. Even if the backend mysql goes down, tomcat is not suppose to crash (especially, without reporting anything in the log). Rather, it should report an error page upon access and resume working when the database is restored. I thought may be it was a bug in the older version (4.0-dev) so I upgraded tomcat to 4.1.18 (latest, I suppose), but the problem still exhibits. This crashing thing happens even when there is no access to the tomcat server and there is no application installed. The server will simply go down on it's own without reporting anything in the log. Can someone please let me if it's know problem and how one can possibly come around it? It's really annoying to restart tomcat every couple of days (yes, my mysql has a problem, because of which it goes down too frequently, but that should not in any way affect tomcat). Thanks a lot. -- Regards, -Naba -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Newbie: Java Mail Problem
David- It looks like something strange is happening with your configuration. I am not familiar with the example that you are talking about, but if you look at the exception, it looks like it is trying to connect to port 25 (smtp) of localhost, and not your verizon SMTP server. Localhost normally resolves to your own machine (your XP box in this case), and I doubt you have an SMTP server running there, and thus the connection failure. Perhaps there is another location you must use to specify the verizon server? On a related note, be prepared to potentially have problems once you have the example pointed to the right server. Not all servers allow ad-hoc connections to their SMTP server. If you find yourself in this boat (it pointing to verizon but still getting connection failures) let me know and I can try to step you through debugging SMTP connectivity errors.

Here I tried with max heap size too(-Xms256m -Xmx256m), ending with no result. What I thoght is sun jvm is not properly handling memory allocation/dealloctaion on redhat 7.2/7.3, so I tried with IBM jvm 1.4 on redhat 7.2 with tomcat 4.0.4.

I beleive we are dealing with a different problem. My app has been running on Tomcat 4.0.6 for weeks until I had the problem recently. There was no crash. What happened was, it seems, a user REALLY fat-fingered the enter key or some smart person sent the same request to the server 180 times within one minute. I traced back through my access logs for Apache and caught the massive number if requests for one URL at the same time I had the problem. All of these requests overwhelmed the number of AJP13 processors I had configured (well, they are still at the default setting) and also caused a massive opening of database connections. Anyway, as to your problem: You may not have enough memory setup for your JVM. Do you send amx -Xm and -Xs parameters to Tomcat using JAVA_OPTS? You may be getting more load then Tomcat can handle due to a RAM constraint.

If I understand the stuff below, after 85 concurrent connections (max connections + accept count) I would start getting the Out of Processors error.

RE: Newbie: Java Mail Problem
On that note, if you're using Windows 2000 and XP Professional, you can simply install a SMTP service on your computer. It's part of IIS, though, which means you'll have to install that if you haven't already. If you want to see if you have it installed, goto Start-Control Panel-Administrative Tools. If you have it installed, you should see a shortcut there that says Internet Information Services. Open that up, and you can configure both IIS and any of it's related services, including SMTP. If you don't have it installed, and want to install it, goto Start-Control Panel-Add or Remove Programs and click on Add/Remove Windows Components. You'll be shown a list of things that you can install, one of which is IIS. Might be overkill, though, and if you do install it or have it running, you want to make EXTRA sure your computer isn't visible to the outside world on port 25. You can configure the SMTP service to deny connections from anything but localhost, for example. John -Original Message- From: Burden, Parker To: Tomcat Users List Sent: 12/30/02 8:56 AM Subject: RE: Newbie: Java Mail Problem David- It looks like something strange is happening with your configuration. I am not familiar with the example that you are talking about, but if you look at the exception, it looks like it is trying to connect to port 25 (smtp) of localhost, and not your verizon SMTP server. Localhost normally resolves to your own machine (your XP box in this case), and I doubt you have an SMTP server running there, and thus the connection failure. Perhaps there is another location you must use to specify the verizon server? On a related note, be prepared to potentially have problems once you have the example pointed to the right server. Not all servers allow ad-hoc connections to their SMTP server. If you find yourself in this boat (it pointing to verizon but still getting connection failures) let me know and I can try to step you through debugging SMTP connectivity errors.

Re: session id's really unique?
You run the risk of getting duplicate session id's. However, across contexts you'll have separate Managers, and therefore different sets of sessions. So, you don't run the risk of one context gaining access to another context's sessions. The risk is the one discussed in the other session id thread where if you get duplicate session id's in the same context. Then you've got serious problems. shawn wrote: If I use RequestDispatcher.forward(request, response) to another context am I running the risk of session id conflicts? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Virtual Hosting with Tomcat
I'd say to just send requests directly to Tomcat on it's port..usually 8180 or 8080 http://yoursite.com:8180 then edit the server.xml file to point to where you want it to serve your webpages. Here's an example config: Host name=yoursite.com Context path= docBase=/home/mydirectory/public_html debug=0/ Aliaswww.yoursite.com/Alias /Host you'll put that in your server.xml file in between: Service name=Tomcat-Standalone !-- Define the top level container in our container hierarchy -- Engine name=Standalone defaultHost=localhost debug=0 Host name=yoursite.com Context path= docBase=/home/mydirectory/public_html debug=0/ Aliaswww.yoursite.com/Alias /Host /Engine /Service -Original Message- From: Mike Rixford [mailto:[EMAIL PROTECTED]] Sent: Monday, December 30, 2002 11:31 AM To: Tomcat Users List Subject: Virtual Hosting with Tomcat Hi there, I need to setup virtual hosting with Tomcat.

My listener is called twice while the following line Context path=name docBase=x debug=0 loads it only once. What am I missing ? Appreciate help. Let's think for a moment about how Tomcat auto-deploys applications from the webapps subdirectory. Basically, it does the following: * Scans all the Context elements that you've created, and deploys an app under the context path you specified. In the case of your first example, you're creating the root webapp for this virtual host from the contents of $CATALINA_HOME/webapps/x. * Scans all the directories in webapps to see if they contain a web application. If so, they are deployed under a context path derived from the directory name. So, Tomcat sees directory x and deploys the *same* webapp under context path /x. If you do not want this to happen, you need to either ensure that the directory name matches the context path without the leading slash (use special directory name ROOT for the root webapp, since you cannot have a zero-length filename on most OSs), or put your context directory someplace other than webapps and use an absolute path for the docBase attribute. So why didn't your second example load the app twice? Simple -- name is not a valid context path because it does not start with a slash, so this Context entry was not loaded (although I'll bet there are log messages that would tell you about this).

RE: running tomcat as a non-root user?
Additionally, you can add the su tomcat -c in a wrapper script that calls the startup.sh file. Mine looks like this: case $1 in start) echo -n Starting Tomcat... /bin/su tomcat -c /usr/local/tomcat1/bin/startup.sh /bin/su tomcat -c /usr/local/tomcat2/bin/startup.sh ;; That way, you CAN use root (and a startup script) to start Tomcat and still get the security benefits of running as an unpriveledged, locked user.

Tomcat connection pool parameters??
We are implementing the Tomcat 4.1.12 connection pooling. We have 4 different datasources bound to different databases with the same connection pooling parameters except for the database url. We are into a strange problem where Tomcat closes the connection after a period of inactivity(around 2 mins) and when we try to establish a connection to it, an Exception saying closed connection is thrown. Some times it says SQlException: Exhausted ResultSet and if the jsp page which is trying to retrieve the connection is refreshed after a while I get an Exception saying End of TNS data channel. Does anyone have a configuration for the Tomcat connection pooling that has worked out well..Is there anything that I am not setting right in the server.xml?? Any suggestions will be very helpful..

problem: cannot use Tomcat's container managed securitythrough ISAPI filter
I'm using security-constraint to restrict access to the manager and other applications. I've had no trouble using both Memory and JNDI realms when accessing through the Coyote HTTP/1.1 Connector, but not when I use IIS and the isapi_redirector.dll (or isapi_redirector2.dll). With the ISAPI filter, my login attempts are rejected and the Windows security log suggests the attempts are going against the Windows domain rather than the tomcat realm. The isapi_redirector2.dll application log entries suggest something called jk2_service_iis_get_roles in the ISAPI filter is attempting to determine the role of the user rather than letting Tomcat do this. Is there a way to use Tomcat's container managed security through the ISAPI filter? TIA!
RE: running tomcat as a non-root user?
Additionally, you can add the su tomcat -c in a wrapper script That is basically what I do. It has the advantage that you can put different tomcats under different users (and thus enforce file system access). Even better would be to chroot tomcat. I don't have that worked out (yet). --- Noel -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
reducing tomcat jasper memory footprint
Hi, I'm using Apache 1.3.26 and 3 tomcat 4.0.4 instances with AJP13 loadbalancing . Our application is a CMS where all the published articles are generated offline as JSP-Files, one jsp per article. We had hige problems with the memory footprint. Due to the fact that every jsp is generated as a class and there are about 200 new artices per day the permanent segment of the JVM heap gets filled with all the classes, and I get an OutOfMemoryError. My workaround for now is setting -XX:PermSize and --XX:MapPermSize to higher values, but this just delays application hang-up. With 64 megs of permSize our Server had an approx. uptime of 1 day now it's about 3-4 days. Is there any way to unload jsp-Files (unload the class) ? llap, julian

tomcat/apache connector startup failure: NCDFE fprorg/apache/commons/logging/LogFactory
Having trouble to make ajp13 connector work (jk2 with Apache 2). Tomcat fails connecting initializing with the following error: SEVERE: Can't create apr java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory As a consequence of this problem (I think it is related), I cannot access the dynamic pages from apache. Tomcat works great (http://localhost:8080/examples/) while http://localhost/examples/ returns a 500 Error (Connection refused on port 8019 - errno 111). (nb: I modified the default port to be 8019 instead of 8009). I've tried several variations of the jk2.properties and workers2.properties without success. Spent a lot of time on the mailing lists archives without success neither. I moved the commons-logging.jar from $TOMCAT/server/lib/ to $TOMCAT/common/lib as advised in some mails. This didn't work. Even if if had worked, it seems it would have been inapropriate: see http://issues.apache.org/bugzilla/show_bug.cgi?id=13689 I also used the attached jsp deployed in $TOMCAT/webapps/ROOT to see the CLASSPATH which is outputed as /usr/local/java/lib/tools.jar:/opt/tomcat/bin/bootstrap.jar which seems normal to me. I didn't try to modify the CLASSPATH in catalina.sh as it doesn't seem like the correct thing to do neither. It seems like this is a ClassLoader problem. If there is a way to enable debugging for the class loader, I am also interested. I found this: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/loader.html But didn't find yet how to use it.

Apache HTTPD Tomcat: Where does mod_jk step in?
Ladies and Gentlemen: I'm using Apache 2.0.43 and Tomcat 4.1.12 with JK on Win2K. I'm using the JkMount directives to send all requests to /servlets/ and /*.jsp to Tomcat. However, I need to know where in the server processing JK actually intercepts those requests and shoots them off to tomcat, and what preprocessing Tomcat does to them afterwards. Can Tomcat use it's own Realms to handle authentication or does Apache need to do that? Do aliases map the request in Apache before JK grabs them? WORKFLOW. That's what I need to understand. Does anyone know much about that? Is there some documentation available somewhere on this workflow? I've ripped www.apache.org and jakarta.apache.org apart and found nothing. Help me, Obi-Wan Kenobi.

Re: reducing tomcat jasper memory footprint
Hi, I use jikes to compile the pages. Since raising the JVM permanent segment size delays the error the problem seems to come from the sheer size of the loaded class files. So theorectically it shouldn't matter wheter the pages are precompiled or not. Anyway I 'm about to set up a test specifically for this, to measure how many pages can be loaded before an error occurs. llap, julian - Original Message - From: Jerome Lacoste (Frisurf) [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Monday, December 30, 2002 8:51 PM Subject: Re: reducing tomcat jasper memory footprint Could this be also related to the leaks of the java compiler?

RE: tomcat as service
Mine worked out of the box as well. However, after stopping the NT service, starting the server using the batch file, deploying a war, shutting the server down via batch, restarting it via batch, confirming it runs without errors, shutting it down via batch, and THEN attempting to starting it as a service, it wouldn't start but there were also no errors.

RE: reducing tomcat jasper memory footprint
One question with regard to using jsp files as included content: I'm having a requirement to include files with more or less simple html content. That's in order to make editing easier for other users. I currently keep some html content in files which I reference by a database id. So a view jsp file is taking some content directly from the database and some by including a file with a name like content[ID].jsp But because I need session tracking and the possibility exists that i have url links in the included content from time to time, I decided to have jsp include files instead of html. Otherwise I couldn't use encodeURL to add session ids for browsers that disallow cookies. Actually it's unlikely that I'd use more Java than this encodeURL() so I would consider using some other technique to do it, if I knew another way. The only thing I could think of would be a filter servlet to encode the urls of those include html files on-the-fly. Any better or easier ideas? Michael -Original Message- From: Justin L.

Re: reducing tomcat jasper memory footprint
Hi, My problem isin't javac memory leakes. Due to the apache/tomcat documentation I was aware of this an setup jikes as my jsp compiler. I'm also using JDK 1.4.1 so the javac issues should be solved, nonetheless. The main problem is as follows: 1. Every article every page in general is a jsp page 2. All the pages are generated by a legacy CMS-System (imperia) and I can't change the structure of it's works. 3. Every jsp page, once loaded, consumes memory, since the class remains loaded. 4. We have 1000s of pages , every day some 200-300 new, so memory use increases. Conclusion: The way we use jsp's for a cms is faulty. But I can't do anything about this. Increasing permSize of the JVM helps a lot. Maybe it would be a good idea to include some hints about -XX:MaxPermSize and XX:PermSize into the documentation because it really helps lessen the problems. But: Is there any generic way to get a stable tomcat with huge number of jsp's ?

However, across contexts you'll have separate Managers, and therefore different sets of sessions. So, you don't run the risk of one context gaining access to another context's sessions. The risk is the one discussed in the other session id thread where if you get duplicate session id's in the same context. Then you've got serious problems. shawn wrote: If I use RequestDispatcher.forward(request, response) to another context am I running the risk of session id conflicts? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- shawn [EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Ant Build Script Fails to Invoke Manager with install command
Can anyone suggest what's wrong? As a relative newbie, I've been modifying and using the example build.xml file provided with the tomcat-docs. I am using it from Intellij IDEA. It's working fine, except I can't get the install target to work. The catalina-ant.jar file has been added to the Build File Properties Additional Classpath in IDEA's Ant Dialog. I am getting a http 401 authentication error. I have provided a build.properties file in the top level directory and Ant seems to find it ok.

how about a tomcat instance create tool?
I see that there is a manager application, but this only manages one instance of tomcat... How about a tool that would create multiple instances of tomcat, with a virtual host, etc that is templated version of tomcat. In this manner, I can create 10 different instances of tomcat, without worrying about port conflicts, etc. I could do it as a java webapp, or even a webmin module Any interest or thoughts? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
info. on tomcat contexts
Hi, We would like to read up on the context declarations in the server.xml. Our application context listener is called twice. What is the best way to debug this short of plowing through the source code? Context path= docBase=SmartManage debug=0... This type of context declaration loads the context twice. Any pointers would be really appreciated. Even after reading articles on the web on this matter we are not able to come to a conclusion about this.

Re: Warning: messages in catalina.out
The first one is usually just that the client hit the stop button in the browser. At the moment, the AJP13 protocol doesn't support out-of-band messages to tell Tomcat about this, so it just drops the connection instead. The second one is just a warning (which will at least be correct in 4.1.19 :) that the auto-config listener is guessing the location of mod_jk.so/dll. If it's working, you can ignore it.

Re: Apache HTTPD Tomcat: Where does mod_jk step in?
Now that we are done attacking clones :) The workflow is pretty simple. In the map-to-storage hook, mod_jk detects that the request should be handled by Tomcat, and registers itself as the handler. Later, when the handler hook is called (I forget the name for Apache2, and don't feel like looking it up :), mod_jk passes the request information (e.g. RequestURI, RequestMethod, Headers) to Tomcat, who then processes the Request normally (i.e. not much differently than if it had been recieved by the HTTP/1.1 connector). The Connector also aranges to send the data in the Response OutputStream/Writer back to mod_jk as the data is available. When mod_jk recieves the output, it sends it back to the client. It's been a while since I've gone through the Apache2 hooks, but I believe that Alias directives aren't handled in map-to-storage, so they should be orthoganal to the mod_jk directives (which is useful when you want Apache2 to serve static content). Unless you set tomcatAuthentication=false on the connector (and don't configure security via Apache directives), then Tomcat's Realms will handle all authentication/authorization. But it is not a two-way thing. You need to set 'JkMount /MyApp/protected/* ajp13' to prevent Apache from serving static content without authorization.

Ladies and Gentlemen: I'm using Apache 2.0.43 and Tomcat 4.1.12 with JK on Win2K. I'm using the JkMount directives to send all requests to /servlets/ and /*.jsp to Tomcat. However, I need to know where in the server processing JK actually intercepts those requests and shoots them off to tomcat, and what preprocessing Tomcat does to them afterwards. Can Tomcat use it's own Realms to handle authentication or does Apache need to do that? Do aliases map the request in Apache before JK grabs them? WORKFLOW. That's what I need to understand. Does anyone know much about that? Is there some documentation available somewhere on this workflow? I've ripped www.apache.org and jakarta.apache.org apart and found nothing. Help me, Obi-Wan Kenobi.

Re: Please reply--Important print writer problem.
You should not ever attempt to use an OutputStream from a JSP page. The
entire point of JSP pages is to output text! JSP pages will always grab the
Writer (per the spec), before your code has a chance to execute.
I'd suggest converting your JSP to a Servlet (not hard, based on the code
below). You should then be able to use the OutputStream happily.

Hi Friends,
I am receiving the sam eproblem which you have put on the site.I am
following MVC architecture and working with IBM WPOrtal server.I have my JSP
packaged within the par file(PORTLET ARCHIVE).I have a code in my JSP which
writes some zip content to the browser using servletoutput stream The aim is
to download the zip file to the client machine my invoking the browsers
default download box.This works fine if i have the JSP outside the PAR file
but when i have this JSP inside the par it gives the exception.
java.lang.IllegalStateException Writer has already been obtained.
Please let me know the solution ASAP.Its important for me.

Console output in Tomcat
Hi all, When I used Java Web Server, it ran in the console, and if I had a statement like System.out.println(someValue) in my servlet, I was able to see the output on the console. Where does all this output go in Tomcat? I am not able to see anything printed by System.out.println().
