My suspicion would be that you have mismatched versions being picked up.
I'd search across your entire system - both client and server - unless
it is all on the same box, and see how many versions of these are lying
around.

I'd also check the version of the JRE. The release notes should tell you
which is the minimum version of the JRE that will work with a particular
version of InterClient. (You may also find you get bitten by the wrong
link in /usr/lib/java, but that is more of a Java problem).
