Subject Re: EJB Entity Cache in Geronimo 2.1
Date Fri, 22 Feb 2008 14:36:08 GMT

I've noticed memory (which is available to the JVM) isn't being used leading
me to believe it's not caching any entity beans.  Every call to a finder
method hits the database.

Does G2.1 not support caching of CMP 2.1 beans, or is this a configuration
