| | | How store java.sql.Connection in Statefull SessionBean ? | How store java.sql.Connection in Statefull SessionBean ? 2003-11-24 - By Paolo Bacco
Back
Hi all,
I deal with an old J2EE container (OAS), EJB 1.0 specs compliant, which allows
to create only statefull Session Beans.
I tried to create a simple application where each session bean holds its own
connection to database (so it performs commit/rollback operation according
client requests).
My question is how manage Connection in my Statefull Bean.
I know that java.sql.Connection  has to be declared as transient member, because
Session Bean could be passivated by container, so how could I prevent loosing
connection?
I guess that a solution is to give that connection to another object in
EjbPassivate() method and acquire it in EjbActivate(), but neither I can store
any object in EjbSessionContext, nor I can store Connection in JNDI service
(because is not serializable again).
Someone can help me?
Thanks,
Paolo Bacco - Italy
