I have had install problems with Limewire on Red Hat 8.0 that are exactly like those described by others in this forum. I have tried both the Sun 1.4 SDK and the Sun 1.4 jre. I could not get Limewire to install on either even though I would get the following output when running the 'java -version' command:

java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

When I ran a 'which java' command, it came back with /usr/bin/java instead of /usr/java/j2re1.4.1_01/bin/java.

rpm -q --whatprovides /usr/bin/java pointed to the jdkgcj rpm.

rpm -e --nodeps jdkgcj and voila! Installs like a charm.
