Read-Only Bean Good Practices

For best results, follow these guidelines when developing read-only beans:

• Avoid having any create or remove methods in the home interface.

• Use any of the valid EJB 3.0 transaction attributes for the trans-attribute element (or @TransactionAttribute annotation).

  The reason for having TX_SUPPORTED is to allow reading uncommitted data in the same transaction. Also, the transaction attributes can be used to force ejbLoad.
