Java AWT on Linux?

[dhboy]

Greetings,

We have installed Linux 2.0.29 and Java 1.1. We can run class files that
do not access the AWT but when we try even simple AWT code we get the
error listed below. We have used ldconfig on the directory
/usr/local/java/lib/i586, but the problem persists. The file
/usr/local/java/lib/i586/libawt.so exists and is not a link.

We are new to Linux (we know Java), can someone help?

[root@sc java]# java Hello

Look's like you're trying to use the JDK with shared Motif libraries
when you haven't got Motif installed on your system. Try downloading
the statically linked version.

Subtlety is the art of saying what you think...
and getting out of the way before it is understood.

I don't know if this is relevant,
but you can set the environment variable LD_LIBRARY_PATH
(in Unix generally).

Solution:

add '/usr/local/java/lib/i586' to /etc/ld.so.conf and run 'ldconfig'
