tomcat-dbcp interceptors
Hello Tomcat users, I have couple of tomcat-dbcp related questions: 1) Can tomcat-dbcp be used outside of tomcat e.g. in non-web apps? 2) If yes, are all features available as when used within tomcat? 3) Most importantly are custom interceptors supported when tomcat-dbcp is used outside tomcat? 4) Can custom interceptor influence/extend connection validation? Would like not only to configure validation query but also to add extra logic which would process result of the query. 5) Are there any examples, documentation, blog posts showing implementations of custom interceptors? Thanks in advance! Regards, Stevo. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: tomcat-dbcp interceptors
1) Can tomcat-dbcp be used outside of tomcat e.g. in non-web apps? Yes, but tomcat-dbcp is exactly the same as commons-dbcp. You would probably just want to use commons-dbcp. 2) If yes, are all features available as when used within tomcat? It has the same feature set as commons-dbcp. https://commons.apache.org/dbcp/ 3) Most importantly are custom interceptors supported when tomcat-dbcp is used outside tomcat? 4) Can custom interceptor influence/extend connection validation?

Re: tomcat-dbcp interceptors

Log exception logging
Hello, Does there is a way to make tomcat log exception (with stacktrace) thrown by servlet? I do not want my app to do that because I like the way tomcat handles exceptions: 500 error and error page is ok, but I need exception stacktrace to be logged so I would be able to configure logging engine to send me emails and save trace to files and so on.

Give us the exact command you are running. -chris That memory listing is really a snapshot of what's going on in your system. Without more information, it's impossible to say. You really need to do a few things here in order to figure out optimal memory settings. From a systems standpoint: 1. Read about how memory management works on a Linux system. Here are a few quick references (search for more) http://youadmin.net/wiki/Linux:RedHat_meminfo_metrics http://www.redhat.com/magazine/001nov04/features/vm/ http://www.linuxweblog.com/meminfo 2. Run some long term monitoring on your system. vmstat iostat sar Plotting vmstat and iostat over a period of time when your application is being heavily used is useful. Use the above tools to tune your system. From an applications standpoint: You mention a memory leak in your application. Feeding it more memory will just delay the inevitable. You need to fix your leaks. First of all, you need to determine if you have a leak. Tools like JConsole, VisualVM, and mat will help with this. Mark Thomas has given a nice presentation on out of memory issues. He's posted the link in the mailing list several times. I found one link here: http://www.infoq.com/presentations/Diagnosing-Memory-Leaks Once you've fixed memory leaks in your application, you'll then (with information available from the tools above) be able to set appropriate Xmx and XX:MaxPermSize. Note, PermSize issues can be related to classes in your application registering themselves with a class loaded in a parent classloader. When you undeploy or redeploy your application, references stay around and you'll eventually get a PermGen space exception. A good explanation (along with an example to illustrate PermGen issues) can be found here: http://blogs.oracle.com/fkieviet/entry/classloader_leaks_the_dreaded_java In short: 1. Measure system with system tools such as vmstat 2. Measure application with tools such as jconsole, visualvm, mat 3. Fix memory leaks (resource and classloader) 4. Then set memory based on the information from the first 3 steps . . . just my two cents. /mde/ - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: SSIFilter for Tomcat 6.0.33 and Tomcat 7.0.22

Welcome to the list. Your English is just fine. I am currently trying to set up SSI filter on the tomcat for an application that I'm developing. I followed the How to of Tomcat 6 and 7 but it wasn't work properly. Which version of Tomcat are you actually running? If you have a choice, use the latest version available, which is currently 7.0.22. All SSI instructions are similar to !--#include virtual=/ path/ file.html -- Desperately I tried it with tomcat 5.5.34 and this works correctly activating the SSI filter according to your How to. Just to confirm: your setup works in Tomcat 5.5? In the SSI Filter i actived the parameter isVirtualWebappRelative but is a requirementof my application. You need isVirtualWebappRelative to be true, or you need it to be false? When I run on Tomcat 6 I get the following exception: GRAVE: #include--Couldn't include file: /includes/holamundo.html java.io.IOException: Couldn't get context for path: /includes/holamundo.html Can you post your Context element and give us an overview of your webapp's layout? And in tomcat 7 do not get any data from the log. How are you configuring the SSIFilter? What is the problem? It could be one (or more) of several problems. What are the differences between tomcat 5.5, tomcat 6.0.22 and tomcat 7.0.22? Briefly, TC t.t, 6.0, and 7.0 support different versions of the servlet spec. There are many other non-spec-related differences as well. The SSI stuff should be relatively similar between versions because the requirements have not changed very much. I recommend reading the changelog for each version and searching for ssi to see what has changed, specifically: http://tomcat.apache.org/tomcat-7.0-doc/changelog.html http://tomcat.apache.org/tomcat-6.0-doc/changelog.html http://tomcat.apache.org/tomcat-5.5-doc/changelog.html I attach eclipse project application testing and configuration files tomcat 6 and 5 This list strips most attachments. Try copy/pasting into your next post. The only interesting parts of your configuration will be your context.xml file (you *are* using a context.xml file, right?) and the SSI-related portions of your web.xml file. -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk69kc0ACgkQ9CaO5/Lv0PBJnwCgvJSnKp5noY5JgAzBoLhrH8dM iSQAn1Muq4wPhaDmUqYB67cZO46FKzyl =IL9j -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I understand that servlet runs in tomcat's thread-pool. It does not prevent Servlet form using proper logging framework, or those old log() methods in Servlet API. But when my servlet throws exception -- tomcat catches it and displays 500 error. Anyway: I found the error. It was my framework (struts), not tomcat trouble. Tomcat itself logs any exception thrown by filter or servlet. Struts 1 and 2 have different ways of handling exceptions. Both are quite flexible -- you just need to become familiar with the configuration and/or coding required. The struts mailing list is a great place to ask questions, but you certainly should read the documentation before you post. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk69koAACgkQ9CaO5/Lv0PCuLwCgvfTYmNmlvjXYMKSD2nys+SId kN4An0Qi87Sx5IhL6gNLV+KDMnBARA5u =dorn -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
