more problems with OJB 1.0, Weblogic, and MsSqlServer
I have finally reached the point where I am debugging problems with OJB (as
opposed
to XML errors).
I am fundamentally confused about something. I am trying to use OJB in a
servlet (JSP),
using JNDI and JTA, with Weblogic 7 as the app server. Note that we are NOT
using
EJBs. Which set of deployment instructions should I follow, the ones for
setting up
servlets or the ones for deploying under Weblogic? Currently, I am following
both
as much as possible. But for example, the Weblogic instructions talk about
compiling
a startup class - does that apply to me? I would not have thought so.
I am trying to connect with this simple code :
PersistenceBroker broker = null;
try
{
broker = PersistenceBrokerFactory.
defaultPersistenceBroker();
Query query = new QueryByCriteria(People.class, null);
I get the following exception
[org.apache.ojb.broker.ta.PersistenceBrokerFactoryDefaultImpl] WARN: ### No
'def
ault' jdbc-connection-descriptor defined, you could not use the
'defaultPersiste
nceBroker()' method ###

and

Am I approaching this the right way?

You don't have to bind a Startup class to JNDI, it's possible to use
the PB-api as in your example.
If you use extern transaction control (means container managed tx or
UserTransaction) then use the ConnectionFactoryManagedImpl,
this implementation ignores OJB's intern commit calls. Otherwise use
the ConnectionFactoryPooledImpl / ConnectionFactoryNotPooledImpl.
Same thing for OJBTxManagerClass, use org.apache.ojb.odmg.JTATxManager
if tx was controlled by appServer, else use the local version.
Rest of the configuration properties looks fine (hope so).

Strange, because your jdbc-connection-descriptor
set 'default-connection="true"'. Does OJB found the
correct repository file?
Did you have tried using the jcd-alias name?
broker = PersistenceBrokerFactory.
createPersistenceBroker(new PBKey("default"));
or better change the jcd-alias name and try again.
