I am using CMT, so we should not explicitly begin and end transaction.
But i am.
Then why things work properly with JBOSS and Weblogic but not with
WebSphere?


Urgent!Urgent!Urgent!

Any kind of help will be appreciated!

Hi,
I got it working with relatively easy!!

Tip : <property name="net.sf.hibernate.transaction.JTATransactionFactory"> net.sf.hibernate.transaction.WebSphereTransactionManagerLookup</property>

Sample code

session = sessionFactory.openSession();
Transaction transaction =
try{
session.beginTransaction();
session.save(obj); // where ob is ur data
transaction.commit();
}
catch(HibernateException excp){transaction.roleback();}

Also have a look at this article:->

When you are using CMT, you should not begin and commit the transactions. You container will take care of that. I was able to commit the data with session.flush() after the unit of work in WebSphere 5.0 application server.

Is it required to do the session.flush explicitly in teh code OR is it possible to have it in the hibernate-cfg.xml file. hibernate.transaction.flush_before_completion prop to true and hibernate.transaction.auto_close_session to true. Anybody??

I have nearly the same problem with Websphere:
I want to store an unidireconal one-to-many relation between two entities.
The specific entry in the mapping looks like this:

<list name="relations" lazy="false" cascade="all" access="org.hibernate.property.DirectPropertyAccessor">
<key column="BUSINESSPARTNER_ID" not-null="true"/>
<list-index column="RELATION_SORT" />
<one-to-many class="BPAddressCommRelationImpl"/>
</list>

completion to post above:

this code i posted above works fine. But if i change the not-null of the key-column to "false" the relation is not stored, that means the value in the index-column of the relation is null

I have tested the problem with a JUnit test case, therefor i changed from CMT to manual transaction handling. There i can change the not-null value to "false" but in that case i have to save both members of the relation in one transaction.

Now finally my question is:

What i have to do to get Webspere saving objects, that have a relation, in one transaction ?
