Thanks for the help--this is an instance where forums came through...

As it turns out, I don't think that IBMJava2-1.3 will work with limewire. This might be important info for users who install the IBM jre from the redhat 7.1 app-disk.

Anyway, I used sun's jre and, wammo! success...

Question off-topic: is there any way to view limewire upload stats to see number of total uploads and names of files uploaded?
