Trouble running code on Windows [message #870853] Wed, 09 May 2012 23:22 Go to next message

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.

Hi there Jesse, you need to download the swt jars for each operative system. Java is portable, but SWT not totally.

How would you go about doing that in Eclipse? Thanks

You have 2 basic choices:
1) Package separately for each platform (win32/win64/gtk32/gtk64/etc)
Not too difficult with a little ANT-fu. It does mean you then have
multiple platforms end products. This is the route Eclipse itself has taken.

2) Package all the different platform jars and decide at runtime which
set to load.
There are some tips on how to do this here:
http://stackoverflow.com/questions/3959556/problems-with-loading-resources-during-execution

This is how I've tackled the problem. Each SWT platform jar goes in its
own subfolder win32\win64\etc. The main class detects which platform its
running on and then creates a new classloader with URLs that include
that subfolder in the path. It then launches the rest of the application.

All this is packaged up into one runnable jar using ANT.

I'm messing with that code given in the error trying to get it to chainload my program. Two questions.

1) What does your ant build script look like?

2)I have completely forgotten and will probably ask later Cool

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.
