I have a few questions about Orion and transactions: 1. How do I set the transaction isolation level (read_committed, read_uncommitted etc.). I found that this parameter is set by Orion in orion-ejb-jar.xml. Should I not be able to do this explicitly? What is the default? 2. A general EJB design issue (Not specific to Orion) I have a session bean that handles requests from a servlet. The session bean uses a number of BMP entity beans to interact with the DB. My entity beans will always be called from the session bean that programmatically handles the transactions. I store my session bean and entity beans in separate jars. In one public method of the session bean, I will be able to: a. Start a transaction. b. Add/update/delete a couple of entity beans b. Commit the transaction if everything went fine or rollback it if something bad happened. My question is: What kind of transaction attribute values should I use in in the deplayment descriptor for the session bean and the entity beans? /Thanks in advance, Mattias Arbin
