I'm having a problem with JLink in Mathematica 6, on OSX 10.5, with Java SE 6 (64 bit). In particular, I get error messages LinkConnect::linkc: Unable to connect to LinkObject['/Applications/Mathema<<92>>/ m0000011741", <<2>>]. InstallJava::fail: A link to the Java runtime could not be established. when first loading JLink, and later running InstallJava results in LinkOpen::linke: Error 19 InstallJava::launch: The Java runtime could not be launched. Going to Java preferences, I can switch back to J2SE 5.0 (32 bit) (but not 64 bit), after which the problems go away. For performance reasons, I'd really prefer to be able to use a 64 bit runtime. Does anyone know of a fix for this problem? I don't have the same problem with Mathematica 7, but for now I'm having some mysterious problems in Mathematia 7 (my existing packages randomly hang...?) that I'd like to be able to switch back for a while. thanks, Scott Morrison
