    JBoss reloads old versions of classes

    gunbuster Newbie

      Has anyone else had this problem? We'll start up JBoss 3.2.2 (on solaris) just fine, and it'll hum along. We do something like modify a configuration file, then touch the WEB-INF/web.xml for a webapp -- then SOMETIMES, the webapp will reload, but be pulling old versions of the classes from somewhere!

      Where could Jboss be storing some of these ancient versions of these classes? or is our box just spooked? It is really most bizarre -- we've seen code being run that was replaced months ago...

          That does sound strange...

          check however your tmp dir for old deployments. I don't know how it could be picking those up though.

            Hmm.. I found out what was happening, but it still seems strange to me. Perhaps the behaviour of the classloader changed from Jboss 3.0.6 to 3.2.2 ?

            Here's what is happening, we have a webapp deployed as test.war. In the same /deploy folder there is a webapp, test2.war.

            test2.war is an old copy of test.war that some developer left around. When touching the web.xml in test.war, we suddenly find that a number of the classes being picked up are those from test2.war.

            I also noticed this in another instance, where I had two classes with the same package and name, in two different webapps. The method signatures for one was a superset of the other. However, when trying to invoke those methods, the JSP compiler would complain about the method being an undefined symbol. So it appears that though I was working from webappA, it was picking up the class in webappB.

            Is there something significantly different in the way classloading was chagned in 3.2.2? I suppos I need to RTFM, but if there is a quick answer -- that would help greatly!
