I experienced that LimeWire works properly with SUSE8.0 if only the correct java-version is on.
Changing the old java-version, that YAST2 installs by default via bash may not be that trivial for non nerds so i found an easier way to switch from jre1.1 to the needed jre1.4.

1) download the jre1.4 RPM of your choice (i prefer SUN) and install it.
2)login as root and open /usr/lib/java
3)rename the folders you find here by appending _old to theire names
4) open /usr/java , copy the folders inside and drop them to /usr/lib/java
5)close the folders and restart, login as normal user and run the starter-shellscript that came with lime.
6)SHARE ;-]]

the advantage is, that you dont have to change any internal settings of SUSE 8.0 and you can do that without typing any powerfull commands in the bash
All simple drag`ndrop mouseoperations.
If this should cause trouble, simply erase the folders you have dropped into /usr/lib/java and rename the old ones by deleting the _old you have appended before.
Everything in the state of virginity again...
