Hi Dormand.
I've tried using this:
//previous declaration.
private static final PersistenceManagerFactory pmfInstance =
JDOHelper.getPersistenceManagerFactory("transactions-optional");
PersistenceManager pm =
getPersistanceManagerFactory().getPersistenceManager();
Object foundObject=null;
try {
// the getObjectById metho receives your key to make
the search.
Key k=<The Key of your object>;
foundObject = pm.getObjectById(classType, k);
}
finally{
pm.close();
return return foundObject;
}
in the other hand, I've tried to make the query just the same as
you've, but, somewhy, it didn't work out. So I decide to do it by the
given method by the Persistent Manager Object.
Hope this helps.
Rgds.
