Hi,

We have a Netware v6.5 SP7 server with iManager 2.7 . We have just installed
BorderManager v3.9 SP1 and have configured in iManager and have running
ACL's/Proxy. This is working as designed.

We now wish to setup VPN for the first time but each time we select VPN
Services in iManager we get returned "System Error - unknown error" and when
we look in details the following is displayed:

Upon looking on the logger screen of the server the following is displayed
when VPN Services is selected in iManager: Task 514 ....
java.lang.incompatibleclasschangeerror

I reapplied the VPN schema extensions also uninstalled and installed the
VPN.NPM from BroderManager v3.9 SP1 plus restarted Tomcat - same error
occurs. Nothing shows up in the forums or the Novell site regarding this
error.

Does anyone know what might cause this and how it can be rectified. Until we
correct this we cannot configure VPN Services at all.

Cheers,
Dale.
