redeploy your EAR?
I have my JSPs and class files unpacked. I don't see the changes to my class file until I restart. For example, changes to a java bean do not appear until restart.
try packing your app into an EAR and redeploy the application (rather than restart the server) and see if that helps
Also, if you haven't already, you should try updating to the latest JBoss 3.0 bug fix release.
I'm facing the same problem: deploying the myApp.war-file works fine, but if I change only a class-file, e.g. a servlet, it is not reloaded automatically while the JBoss/Tomcat bundle (jboss-3.0.3_tomcat-4.1.12.zip with w2k) is running.
At Tomcat stand-alone it is possible to add the -tag with the reloadable-attribute to the server.xml - but where to put similar settings at the JBoss/Tombat bundle?
