Hi,

I want to create a number of records in a database-table in let's call it a batch.

To update the table I have an entity bean.
The batch processing is managed by a stateless session bean that creates a lot of entity-bean instances (via the create method).

The code below is a simplified part of my session-bean-method
(all declarations are done before)

...
for (int counter = 0; counter < primKeys.size(); counter++)
{
key = primKeys.get(counter);

// Find the data in the source table
mySourceRemote = mySourceHome.findByPrimaryKey(primKey);
MyDataObject dataObject = mySourceRemote.getData();

// Some processing

myDestHome.create(dataObject );
}

...

For each item in the loop the data is successfully retrieved from the sourcetable and successfully stored in the destination table.
My problem :
Every time the create is executed, the container calls the ejbStore-method from all previous created entity-beans in the loop.
OK, there's nothing to store an nothing will happen on the database but I don't want this overhead.
Can anybody tell me why this happens ?

I'm using BMP.
The entity bean has transaction attribute : Required.
So the transaction starts when the session-bean-method is called and ends at the end of this method.
All creates are in the same transaction.


Thanx for your help,
Piboe
