Open a terminal and type in
find / -name java
it'll give you something like
/usr/java/j2re1.4.2_03/bin/java
you then need to enter
export PATH=$PATH:/whatever the path it just gave you
for example
export PATH=$PATH:/usr/java/j2re1.4.2_03/bin
It's important that the path ends with bin. Run the LimeWire installer before you close the terminal or it will forget what you just typed in and you'll have to do it all again.
If that doesn't work read this
