Java displays on X11 under OS X?

Maybe I mis-read, or just simply misunderstood the questions. Have you tried using.

<java app> -display <hostname of sun>😮.0

replace "<java app>" with the name of the java application.
and the same for the host.

Is this what you were asking? Or am I way off the mark?

Andy is right - if the Sun allows inbound X11 traffic (no firewall or security) - his suggestion is the easiest. It's purely an X11 thing - so as long as the java app is smart enough to use X11 - not native display for mac - you can get the X11 traffic there (xhost + or other xhost might be needed on the Sun side or ssh tunneling once you have an terminal open to the Sun (and the mac X11 tunneling turned on in ssh...)

Let us know which you choose (traditional X11 network over ports 6000 - setting DISPLAY=sun hostname.domain:0.0) or ssh tunneling and we should be able to help.

As far as I am aware, OS X's java implementation doesn't know anything about X11.

I don't know the details - but oracle's installer worked for me (running the app on AIX/Solaris and seeing the java window here as well as the other way around if memory serves - mac installer viewed somewhere else...)

I'd ask in the developer section what libraries/code java needs for X11. (Or ask the person who supports the java code you want to run)

Java applications typically display GUIs using Swing, which is provided as part of the Java distribution itself. Apple's implementation of Swing knows how to talk to Quartz, not X11. This is to do with the Java vendor, not the vendor of the application you're using.

The Java that comes with the other platforms you refer to have a swing which knows how to talk to X11, so you can just use the normal X11 forwarding procedure to forward it to your Mac.

Hi D7,
I'm pretty sure that you can't do what you want with Apple's Java. Apple has worked incredibly hard to implement the Aqua version of Java but to my knowledge, haven't developed the capability of using multiple windowing systems. The only hope I see for what you're doing is to try to port the source code of a Linux Java to the Mac.

There are a number of options for addressing the problem a little differently. The simplest is VNC. VNC isn't as efficient as XWindows but it will let you run aqua applications. Other possibilities involve moving the data from the Mac to the Sun. Since that could possibly be put on a schedule and done in the background, moving it might not be as bad as it sounds initially. Of course I don't know the circumstances or what kind of data it is so I can't really say much about options. Just remember the Sun motto, "the network is the computer."
