If you try and run JDK1.3.x on Linux x86_64 (AMD64 or EM64T Intel hardware), you may run into the following error:

    Error: can't find libjava.so.

This is not really a system problem, but a problem with the shell script wrappers used by the 1.3.x JDK, as mentioned here.  To get around this, you need to add the output of the 'uname -m' command (should be 'x86_64') to the following files:

    $JAVA_HOME/bin/.java_wrapper
    $JAVA_HOME/bin/realpath
    $JAVA_HOME/bin/ControlPanel
    $JAVA_HOME/jre/bin/.java_wrapper
    $JAVA_HOME/jre/bin/realpath
    $JAVA_HOME/jre/bin/ControlPanel

Change the following case statement from:

    case "`uname -m`" in
        i[3-6]86  | ia32 | ia64 | i?86)
            proc=i386
            ;;

to the following:

    case "`uname -m`" in
        i[3-6]86  | ia32 | ia64 | i?86 | x86_64)
            proc=i386
            ;;

This has been reated on RHEL4 with JDK 1.3.1_13.
