Problem with Hot deployment of Struts application

Question

I used the exploded archive format to deploy a web application ( no EJB Jars etc involved). But after modifying a custom Action class and placing it in the WEB-inf\classes, I get the following exception: java.lang.ClassCastException: org.apache.struts.action.RequestProcessor at org.apache.struts.action.ActionServlet.getProcessorForModule Clearly weblogic managed to load the new Action class, and if I understand correctly it would have destroyed the old web class loader and create a new one and loaded all the classes visible to the web app class loader. But somehow it still seems to cache the RequestProcessor class.. Can some one please throw some light on this.
PS I dont have anything in the server classpath, and there is no chance of duplicate copies anywhere in the classpath or under web-inf

Answer 1

Yes, I added the line getServletContext().removeAttribute(Globals.REQUEST_PROCESSOR_KEY) in ActionServlet's destroy(). It works now.
It was previously getting back the old class reference while doing a getAttribute(REQ....) , so was giving the classcast.
Not sure if this is a bug in the ActionServlet, or if I am missing something.
