[Mav-user] 2.0rc works fine and a "preDiscard" question
Just a little feedback... I'm now on 2.0rc and am not having any problems Great work!! One question though: In my controller objects, I would like to be notified when an instance is about to be deleted. I'd like to use this opportunity to "clean-up", in this case closing a database connection. Can you suggest a way to do this? I would like something more reliable than Java's finalize() method. Or can an overidable method be easily added at this point in the release cycle? Thanks, Dan ___ Mav-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mav-user
[Mav-user] Configuration for Tomcat??
Dear all, I have installed Apache-Tomcat 4.0 on my Windows 2000 machine, and have tried to run the friendbook example, but it doesn't work. I wonder do I need to do any configuration on the Tomcat?? Please help. Thank you very much.

[Mav-user] Howto: Getting the JSP Example Working
Here is a step-by-step for getting the examples working with the Sun JDK 1.4 and Tomcat 4.0.3 (JDK 1.4 dist.) on WinXP Pro. 1.) Install the 1.4 JDK. 2.) Install Tomcat, make sure it is working. (For future ref tc = Tomcat install dir) Note: I used the "jakarta-tomcat-4.0.3-LE-jdk14.zip" dist. Expanded it to /temp, ran bin/startup.bat, and pointed my browser to http://localhost:8080/index.html to test the install. 3.) Deploy the example (these instructions are also in friendbook-jsp-readme.txt) a.) Get Latest Maverick - 2.0 RC b.) Copy maverick/dist/friendbook-jsp.war to tc/webapps c.) Copy maverick/lib/log4j.jar to tc/lib 4.) Restart Tomcat and navigate to http://localhost:8080/friendbook-jsp You will receive the following output: Starting service Tomcat-Standalone Apache Tomcat/4.0.3 log4j:ERROR No appenders could be found for category org.infohazard.maverick.Dispatcher). log4j:ERROR Please initialize the log4j system properly. Starting service Tomcat-Apache Apache Tomcat/4.0.3 To init the log4j system, read this FAQ: http://mav.sourceforge.net/maverick-manual.html#faq HTH, Scott ___ Mav-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mav-user
RE: [Mav-user] Howto: Getting the JSP Example Working
In addition to Scott's instructions, if you're using the JDK 1.3, you'll have to add the JAXP classes to your environment. Put the maverick/lib/jaxp.jar in your tomcat/lib directory. If you are using XSLT, you'll need a processor as well; the latest Xalan release (download separately) works fine. The JDK 1.4 has both the JAXP and Xalan classes in the standard platform. If this doesn't work, let us know what the error is.

RE: [Mav-user] Howto: Getting the JSP Example Working
Dear Jeff Thousand thanks for your tip. I got this error when I start up the Tomcat: log4j:ERROR No appenders could be found for category (org.infohazard.maverick.Di spatcher). log4j:ERROR Please initialize the log4j system properly. What does it mean??? And when I run the friendbook example, the following problems happened: javax.servlet.ServletException: Servlet.init() for servlet jsp threw exception at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:875) ... ... Root Cause: java.lang.SecurityException: sealing violation at java.net.URLClassLoader.defineClass(Unknown Source) ... ... Something wrong with my configuration, I presume... Please help. Thank you very much. p.s I am using JDK <1.4. thank you very much.

RE: [Mav-user] 2.0rc works fine and a "preDiscard" question
I'm not quite sure what you mean. Why not just at the end of your perform() method? Or are you using a ControllerSingleton, and you want to be notified when a new configuration is loaded and the old is being discarded?

It means that the logging system is not initialized :-) Scott included a link to the FAQ in his email: http://mav.sourceforge.net/maverick-manual.html#N10722 If you do not desire detailed logging information, feel free to ignore the message. > And when I run the friendbook example, the following problems happened: > > javax.servlet.ServletException: Servlet.init() for servlet jsp threw > exception > at > org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:875) > ... ... > > Root Cause: > java.lang.SecurityException: sealing violation > at java.net.URLClassLoader.defineClass(Unknown Source) > ... ... Hmmm, sealing violations. I have heard much about these but not experienced them myself. Which exact versions of tomcat, jdk, and xslt processor (if you're using one) are you using? And what is the remainder of the Root Cause stack trace? Jeff Schnitzer [EMAIL PROTECTED] ___ Mav-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mav-user
RE: [Mav-user] Howto: Getting the JSP Example Working
I've got to admit that that stack trace doesn't offer me any clues. You should probably upgrade to the 4.0.3 version of Tomcat, because there are some security issues with prior versions. I would also try updating to the latest version of Xalan (you are using xslt, right?). Switching to JDK1.4, of course, is an option :-) Does anyone else understand sealing violations?
