We use the little "manager" servlet/application. As I recall there is a pretty good "HowTo" on it for Tomcat 4.

For example, my java and class files are in TOMCAT_HOME/webapps/ROOT/WEB-INF/classes/com/complusdata/beans/ and there is nothing in here is nothing in TOMCAT_HOME/common/classes/ so I would imagine the higher classloader scenario you gave wouldn't apply... Why is it then that whenever I make a change to my java file and recompile, I have to restart Tomcat in order for the changes to take effect. Is there a better way to do this?

For instance: TOMCAT_HOME/webapps/your_app/WEB-INF/classes/com/example/MyClass.class TOMCAT_HOME/common/classes/com/example/MyClass.class The 2nd one would be loaded prior to first because it will be loaded in a higher classloader. As for the touching of the web.xml file to reload the class. This only works for classes loaded in the web application's classloader, and not for classes loaded within tomcat's internal classloader. I don't have the specific Tomcat classloader hierarchy on hand, but I can tell you that a change made outside the context of your app to a class loaded within common/lib or server/lib requires a restart of Tomcat. _________________ Jeremy Nix Senior Application Developer Southwest Financial -----Original Message----- From: Jacques Capesius [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 21, 2003 12:31 PM To: 'Tomcat' Subject: [beginner question] reloading classes Hi folks, I'm new to Tomcat, but not as new to J2EE. I have a jsp, and I made a change to a class that's being loaded into it as a bean, but I can't get the page to use the new class and not the old one. My question, thus, is: when I make changes to a class, how do I get Tomcat to reload the class? Restarting Tomcat doesn't seem to do the trick. Searching the web, I found a doc that made mention that "touching" the web.xml file would force the reloading of the class. I tried that and it didn't work. I also read somewhere that going to the application (where the JSPs are) and typing ANT would force the recompile of everything. Still, the old class is being used. I'm storing the class in %catalina_home%/classes/PSQ/. I'm loading it into the jsp by means of the following line of code: <jsp:useBean id="psq" class="PSQ.PSQ" scope="session"/> I've made sure there are no other versions of PSQ.class in any other places it might be used, for example, the WEB-INF/classes directory. Thanks for whatever advice you can give, and I apologize if this question has been asked many times before. -jacques :) Jacques Capesius CNT Web Marketing Developer [EMAIL PROTECTED] (763) 268-6749 -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
