Hi,
I am trying to store a file in Datastore in the form blob. while running
the code am facing the below error.
anybody knows why this error is throwing? pls advice me on this to resolve
this issue.
javax.jdo.JDOUserException: You have either specified for this PMF to use a
"persistence-unit" of "transactionas-optional" (yet this doesnt exist!) or you
called JDOHelper.getPersistenceManagerFactory with "transactionas-optional" as
the name of a properties file (and this doesnt exist in the CLASSPATH)
