Re: JAVA_HOME problems after upgrade

Quoting Nathan Kinder <nkinder@xxxxxxxxxx>:

FDS 7.1 included the IBM JVM. FDS 1.0 does not include a JVM. To use Console you need either the 14.2 Sun or IBM JVM on your system with JAVA_HOME set appropriately.

-NGK

A suggestion - since Red Hat packages and distributes RHEL with Java RPMs from IBM, and since jpackage-utils puts some nice reasonable defaults in /etc/java/java.conf for Java variables, and since Red Hat now has a directory server that uses Java for management, how about modifying startconsole to check /etc/java/java.conf first? :)

The following should hold true:
LIBJAVA_DIR=JAVA_LIBDIR
LIBJVM_DIR=JAVA_JVMDIR

The startconsole script didn't work for me to automatically detect LIB{JAVA,JVM}_DIR, based on the output of find/sed, so I just hardcoded to the above, which is what they would have ended up as anyway. But after just digging a little bit, the reason appears to be that "find /usr/lib/jvm/java -name 'libjvm.s[ol]'" returns nothing.

But:
cd $JAVA_HOME (or /usr/lib/jvm/java)
find . -name 'libjvm.s[ol]' returns ./bin/classic/libjvm.so

or probably better,

find $JAVA_HOME/ -name libjava\.s[ol]

works too, so I think the trailing slash after JAVA_HOME is needed.
