Hi anil,

You can use message driven beans..

Based on the message you send, a mdb can be invoked which inturn initiates
the session bean that executes the batch process

Subject: Problem in Using Database.

Hi,

I am trying to do the following.

I am using XA Datasource for DB2/390 from my application. In my application
I am having a session beans and Domain objects and Data Access objects. we
are using websphere Application Server 5.0

We are using XA Datasource because we need to insert and update tables in
multiple databases.

I had a problem when I try to update some records and try to access the same
records in the same transaction. I am getting Invocation Exception.

Here are some questions

1) I want to create a class extending thread and start thread from EJB state
less session Brean so that I can do the update and selection of rows from
the database external to the Global Transaction

Any suggestions.

Thanks

Anil
