[kepler-users] Locations for actor specific libraries and dll's

[ben leinfelder]

Tom -
What you've laid out is spot on in terms of where the libraries (bins  
and jars) should be located. If you follow those guidelines, Kepler  
will make sure the library paths are set correctly when it runs with  
your module.
In my work with native R-to-Java binding libraries I've had binary  
libraries for three different platforms: *nix, OS X, and Windows.  
These seem to play fine in the same sandbox (i.e. lib/ dir).
In your Windows case, hopefully the x32/x64 dlls:
-will have different file names and they can both be placed in the  
same lib dir
-and the jars that load them will be intelligent enough to load the  
correct binary for that os.

I imagine the the code that generates the lib path for Kepler could be  
augmented such that it only looks in certain subfolders (say lib/32/  
and lib/64/) depending on what system it's running on, but hopefully  
this won't be immediately necessary.
