Mouse cursors
We are trying to set the mouse cursor to the wait cursor whenever we open a dialog box. We have method that takes in a java.awt.Component and grabs all of its contained Components and sets the cursor on it. This works with limited success. If there is a List in the main panel and you move the cursor off the dialog box and over the list beneath, the cursor shows up in the busy form - every other time. It's very consistent. One time it will be the little watch; next time, it's an arrow. Over any other component, the mouse never changes. Is this a bug or are we doing it wrong? Even better, is there a better, more "correct" way to do this? I'm using an old method written before I came to the company so I'm not terribly familiar with the workings of mouse cursors in Java. A coworker just hollered something about setting the cursor on a TextField after construction so that it will inherit any changes it to its parent's mouse cursor but I haven't had a chance to look at it yet. Does anyone have any idea? Thanks. -- Justin Lee | It's not the weight of the stone that's holding you down. JEDI | It's the way it fascinates your mind. -- Tourniquet

Portable, interpreted code has been around far longer than that patent. For an example, pick any form of BASIC. Isn't Java just another multiplatform interpreted language?

My understand is that KDE is completely CORBA driven anyway. ( Even though their object model is called KOM ). CORBA integration should be fairly straightforward at that point. GNOME uses CORBA as its IPC ( though only C binding at this point ), so CORBA integration should be easy there too. The trouble is differing IDL defs and system architectures. The good news is that the high-level GNOME and KDE people are trying to unify their IDL defs and foster as much cross-integration as possible. IMO, apps tied to one desktop defeat the purpose of having the option of multiple window managers. I love the KDE object model, but their desktop looks like it was built by a bunch of left-brained scientists who have no lives. Techincally it's a nice system, but aesthetically leaves me wanting more. But that's another discussion altogether. -- Justin Lee | Does is really matter how far you go?

We use make to great advantage. Our system has ~1000 java files and make reduces compile time dramatically. ( We use jikes, too, so that helps. ) Using production rules, make will only compile a java file when the timestamp on the .java file is later than the timestamp on the .class. -- Justin Lee | It's not the weight of the stone that's holding you down.

So we use jikes for dev and when we roll a production build, we rebuild with javac. Jikes may have fixed this ( I think I heard it has to do with sloppy spec conformance on the part of Sun/Symantec ) but I don't know for sure. We're using jikes 0.47 and I think that's outdated. -- Justin Lee | It's not the weight of the stone that's holding you down.

AFAIK, Sun owns the code for the bug fixes that blackdown produces and probably the ported code by virtue of the fact Blackdown used Sun proprietary code to generate it. > Maybe GPL was a good idea after all?

dropped RMI objects
I using 1.2.2 RC3 on RedHat 6.1 and am seeing some pretty funky stuff. I'm doing jsp development with gnujsp and RMI. What I'm seeing is that one of my servers will randomly disappear. ( I get NoSuchObjectExceptions when making calls to it. ) The process that ran it is still running, but the rmiregistry decides to disregard it, I supposed. Doing a 'ps ux' reveals anywhere from 2 to 5 [java ] process that are just hanging out. There are also some other java processes in the listing that shouldn't be there. ( I just killed that process. ) If I kill a few strategic java process, the defunct ones disappear. The main culprit seems to be the rmiregistry. Anyone know anything about this? If it helps, I turned off the JIT ( -Djava.compiler= ). ( btw, I'm also submitting this to the blackdown jitterbug. ) -- Justin Lee "Vergoofin der flicke stoobin mit der børk-børk yubetcha!" - The Swedish Chef -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
