Running extern binary [message #879224]

Hi everybody,

I need to run an external Win32 EXE file in one of my Eclipse RCP Plug-Ins. At the moment I'm using the

Runtime.getRuntime().exec("C:/abc.exe");

to run it and as you can see I unfortunately need an absolute path to the EXE file.
Now my question is, is there any solution to include the EXE file in a Eclipse RCP Plug-In and use a relative path? I know that if one use Java JNI to include extern C++ libs it is possible to include the C++ DLL in a Plug-In by specify the location of the JNI DLL like

System.loadLibrary("lib/nativelib");

So I hoped that I can do the same in the Runtime call

Runtime.getRuntime().exec("lib/abc.exe");

But this doesn't work.

Any idea or solution for this problem? How can I include my abc.exe in a Eclipse RCP Plug-In and call it with a relative path.

Yes it should be possible the only thing you need to make sure is that
the bundle is exploded when installed.

You can do this useing the "Eclipse-BundleShape: dir" header in your
MANIFEST.MF - you can afterwards find the location of the bundle
directory using code like shown in [1] look at
createClassLoaderForDeployedPlugin how to find out the location of a bundle.
