Then you have plenty of support from this crowd... but you'll have
to be a bit patient. There's a learning curve with Linux/Unix that's
independent of Java, but once you've climbed that curve you'll find
yourself knowledgeably using a system that's much less plug-and-play
but much more robust than Windows.
If you've got the JDK1.2 glibc2.1 installation on RedHat 6.x, you should
be able to run java by invoking the script (that's Unix-ese for what they
call batch files in Windows) in the bin subdirectory. There's one catch:
you mustn't be in that directory when you run it. So... from some *other*
directory, run:
/usr/share/jdk1.2/bin/java
(I'm assuming, per your previous postings, that your tree is installed
at /usr/share/jdk1.2).
I'm a little bothered by the "java not found" error. If you make the
mistake of running from that directory, you should see a failure to find
"libjava.so". Assuming you've got the Blackdown installation and haven't
messed with any of the files, the invocation I described above should work.
