Hi everyone, I'm developing a project with Struts and I was wondering if it's possible to get the message resources object in a servlet, which is included in the same project. There's no possibility to get that object with the method getResources(HTTPServletRequest) because the servlet does not extends an Action class. Is there a way t...

I have two applets A and B. They are embedded in separate pages. On destroy, A serializes objects to the local file system. On init, B deserializes these objects. This set-up works fine in Windows. Unfortunately, I have discovered that it doesn't work in Mac OS X. This is because B is initialized before A is destroyed. Does anyone...
