Do I read this right, BrailleBlaster has some classpath locations hard coded inside it? This sounds like a porting head ache. I am thinking of as an example what bother this might give a Linux distribution packager, where may be jars need to be placed in a specific location to fit with the distribution's standard, eg. jars in /usr/share/jar.
I would have thought all classpaths (unless using a custom classloader, but you might make that customisable from the command line) should be configured using the -cp option to the java command.

Alex, There are no 32-bit and 64-bit jars except swt.jar All the others are pure Java. You can specify a classpath on the line that calls java. It will be added to the one that BrailleBlaster uses internally. I'll have more to say after I look at your mockup.

Can you pass in a class path and use it at the same time as the "lib" directory for storing Java jars? Any help with this would be greatly appreciated.

The jar files are platform-independent except for the swt.jar which includes native libraries. I'm not sure, but I think that if the native libraries are compiled for 32 bits they will work on 64 bits, with perhaps a small drop in performance.

There are different versions of the Jars found in the "lib" directory for 32-bit and 64-bit platforms, right? Regards, Alex, On 2011-01-31, at 11:44 AM, John J.

Porting should be as simple as possible.
