The update to J/Link 3.0.2 involved adding a single line of code and I see that there are a couple places where I failed to update embedded revision numbers. J/Link reveals its version information via the JLink`Information` context, and that is really the authoritative, portable way to determine the revision you are using. Rest assured that you do have 3.0.2. >By the way if this really is a Mac OS X problem how come I can run J/Link >applications using version 5 on the same computer that I cannot run J/Link >applications using version 5.1? Because J/Link 3.0 is very different from J/Link 2.1. Anyway, I think Igor has hit the nail on the head with his reply. You don't have the "10.3.8" problem for which J/Link 3.0.2 was created. You probably have the same problem (and the fix) as the user in the link he cited (http://forums.wolfram.com/mathgroup/archive/2005/Jan/msg00286.html). That problem will occur when users copy parts of J/Link into their ~/Library/Java/Extensions/ folder. This is a bad idea in general because it is certain to lead to problems like this every time you update J/Link. The Extensions folder is always examined first by the OS/X Java runtime, so it will load the old version of JLink.jar, which is not going to work with the newer JLink.m file.
