Hie
yeah I did that..
and what I get are two different values from this block
At first time of app startup
vik.sakshum.sakshumweb.jsp.model.jdo.PMF <clinit>: Loading PMF in
com.google.apphosting.runtime.security.userclassloa...@1f7cdc7
and in another flow
vik.sakshum.sakshumweb.jsp.model.jdo.PMF <clinit>: Loading PMF in
com.google.apphosting.runtime.security.userclassloa...@1e6f0ef
So, it means it is trying to load it in two different class loaders. So, how
should I fix it?
Thankx and Regards
