Our code is developed using Eclipse and deployed to JBoss as WAR file. I've recently tried to add an additional method to one of the classes in our package. When I deploy it to the server and then access the site, sometimes it works and other times I get an error saying that the compiler cannot resolve the method (the same one that it just executed a few minutes before.) This problem has happened to me several times. Any suggestions? I never have a problem if I only make changes to an existing method.
