libmapscript.so: wrong ELF class: ELFCLASS64. Java Mapscript woes on AMD64

[Rodrigo Del C. Andrade]

    Hi Umberto, thanks for the reply.

    Silly me forgot to mention I had already tried with -d64 flag, only
to be greeted with a "Running a 64-bit JVM is not supported on this
platform.".
    But all is fine now: I guess a good night asleep jumpstarted the
neurons back,  'cause driving to work this morning it hit me: the JVM  I
am using is 32 bits.
    So I downloaded the 64bits JDK and lo and behold: it's alive again.

    Sometimes *obvious* smacks you in the face and you still cant see it.
    I'll get me coat and leave the building now.

    Thanks.
    Rodrigo


ps: I am forwarding this to the list for posterity's sake.
