Hello, Wolfram? Anyone? I've discovered this is also a problem with Mathematica 7; it just ignores my OS X Java preferences, and runs its own JVM, unless you specify the CommandLine option in ReinstallJava. Could someone at least confirm for me that it's impossible to use Java SE6 through JLink? thanks, Scott Morrison On Feb 10, 2:54 am, Scott Morrison <scott.morri... at gmail.com> wrote: > I'm having a problem withJLinkin Mathematica 6, on OSX 10.5, with JavaSE6 > (64 bit).
