[jboss-user] [JBoss Seam] - Re: Hot Deploy Seam Apps on Tomcat?

[christian.bauer@jboss.com]

For future reference in case anybody finds this thread:

public class SomeServlet extends HttpServlet {

   private static ClassLoader myClassloader;

   public init(ServletConfig cfg) {
       myClassloader = getClass().getClassLoader();
   }

} 

This servlet breaks context reloading in Tomcat, the context leaks a WebappClassloader per reload (and therefore other static variable values, so it can be a lot of memory that is never freed). Since many frameworks (Hibernate, Struts, etc.) use such a pattern, reloading in Tomcat can be considered currently broken.
