Low,
The reason for my original question, was that my JSP jdo code was throwing a
"TransactionNotInProgressException":
Error handling the request: javax.servlet.ServletException:
org.exolab.castor.jdo.TransactionNotInProgressException: Transaction not in
progress -- must open a transaction in order to perform this operation
Here is the code segment:
db = jdo.getDatabase();
try{
db.begin();
oql = db.getOQLQuery( "SELECT m FROM Message m" );
results = oql.execute();
db.commit();
}catch(Exception e){
db.rollback();
throw new Exception(e.getMessage());
}
Is there a problem with this approach???
Thanks,
Brad
