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,
