Error configuring Coherence Cache on Oracle Weblogic server 10.3.4
I'm trying to configure Coherence 3.7 on Oracle Web Logic Server 10.3.4, but when I try to run application on server using eclipse, I get following error.

I've checked with the cache start script and enabled local-storage true in it, but it still doesn't works. Can someone please provide me right steps to configure coherence cache on the Weblogic Server (in web console and in applcation), or suggest me possible reasons why am I getting this error.
Answer
This can happen in a few different cases. Either the storage-enabled nodes are not connected to the storage-disabled nodes (WebLogic in your case) or the storage-enabled nodes don't have SESSION local storage enabled. Confirm that the cluster includes the storage-enabled nodes at runtime and confirm that the cache server is started with the following option:
-Dtangosol.coherence.session.localstorage=true
