I have a bit of a strange issue. I am developing an application using the WindowBuilder and associated libraries. The program works great on my 32-bit Linux box that I have been developing on. However I have two issues.
1) When running the jar on a 64-bit machine, it fails, which makes sense because I packaged the 32-bit libraries in the jar. If someone knows how to make the jar dual architecture, help would be greatly appreciated.
2) More importantly (as my client is chiefly 32-bit Windows XP as most of the world is) I can't run it on Windows. I actually moved the project over to a windows box, set up the WindowBuilder libraries in Eclipse, and recompiled, and it did work. However when I try to use my jar created in Linux, it fails with a message that I will attach (something about needing swt_gtk libraries). Now I'm somewhat new with java, but isn't the goal interoperability? I just find it strange that WindowBuilder seems to be using platform specific code. That being said, any ways around this (ways to make the program work on multiple operating systems) would be fantastic.
Sincerely,
Jesse
Also, I had posted this in the WindowBuilder section, but they sent me here. So my apologies for the duplicates.

Attached are the build.xml and the main starting class
I've modified them slightly from the ones I actually use to remove any
possible reference to stuff I do for work, so there might be some typos
in there.
It should all be fairly obvious, let me know if you have questions.
In the build I'm currently only packaging for Win32/64. Its obvious and
easy to expand to all SWT platforms.

Attached are the build.xml and the main starting class
I've modified them slightly from the ones I actually use to remove any
possible reference to stuff I do for work, so there might be some typos
in there.
It should all be fairly obvious, let me know if you have questions.
In the build I'm currently only packaging for Win32/64. Its obvious and
easy to expand to all SWT platforms.

Attached are the build.xml and the main starting class
I've modified them slightly from the ones I actually use to remove any
possible reference to stuff I do for work, so there might be some typos
in there.
It should all be fairly obvious, let me know if you have questions.
In the build I'm currently only packaging for Win32/64. Its obvious and
easy to expand to all SWT platforms.
