cache.lock with a .NET extend client

696900Sep 14 2009 — edited Sep 15 2009

Hi,

I'm trying to do a simple cache.lock from within a .NET client (C#), connecting to a coherence cache via TCP-Extend.

I get this error

I'm wondering whether I'm configuring my cache incorrectly? I can lock a key from a Java node that joins the cluster .. however, from an Extend node (java or C#), I get this error..

This is a simple distributed cache
