    This article explains how to use updated versions of Sun's JDK with WebObjects 4. This is an unsupported configuration and users should use these instructions at their own risk. Apple will not guarantee or provide support for this procedure.

DISCUSSION

    To install the JDK 1.1.8 and the JDK 1.2 Collection Classes on Solaris or Windows NT:

      • Download JDK 1.1.8 and the JDK 1.2 Collection Classes from Sun's web site.
      • Install the JDK (use the default location of /jdk1.1.8 on Windows NT, /usr/local/jdk1.1.8 on Solaris)
      • Install the Collections (In this example, we will use /jdk1.1.8/collections on Windows NT, /usr/local/jdk1.1.8/collections on Solaris)
      • Create the following environment variables:
    JAVA_HOME /usr/local/jdk1.1.8 (or c:/jdk1.1.8 for NT)
    JDKDIR $JAVA_HOME
      • Edit $(NEXT_ROOT)/Library/Java/JavaConfig.plist to conform to the following:
    Vendor = sun1.1.8
    sun1.1.8 = {
    VM = "$JDKDIR/bin/java.exe";
    DefaultClasspath =  "$HOME/Library/Java; $NEXT_ROOT/Library/Java; $JDKDIR/lib/classes.zip; $JDKDIR/collections/lib/collections.jar";
    DefaultBeanpath =   "$HOME/Library/JavaBeans; $NEXT_ROOT/Local/Library/JavaBeans; $NEXT_ROOT/Library/JavaBeans";
    Compiler = "$JDKDIR/bin/javac.exe";
    Headers = "$JDKDIR/include $JDKDIR/include/winnt";
    Library = "$JDKDIR/lib/javai.lib";
    DebugLibrary = "$JDKDIR/lib/javai_g.lib";

    On Windows NT, this is all you need to do. On Solaris, you'll need to perform some extra steps:
      • Change to the directory /opt/Apple/Library
      • Rename the JDK directory to "JDK1.1.6"
      • Recreate JDK as a link to the $JAVA_HOME directory:
    ln -s $JAVA_HOME JDK

    Be aware that the java compiler used by make is hardcoded to use JDK 1.1.6. This will not affect most Java projects.
