<CODE>

2. // use the default Isolation level.

3. // Likely to be READ_COMMITTED

4. //Ebean.beginTransaction();

5.

6. // start a transaction at SERIALIZABLE

7. Ebean.beginTransaction(Transaction.SERIALIZABLE);

8. ...

9. </CODE>

the above examle shows how you can set isolation level through EBeans

in ejb3 it is not possible to set isolation level programatically if you are using connection pooling,to set refer your servers Docs
if you are not using connection pooling then you can set isolation levels programatically like this

Connection conn=DriverManager.getConnection("URL");
conn.setTransactionLevel(int level);

level 1:READ_UNCOMMITTED

level 2:READ_COMMITTED

level 3:REPEATABLE_READ

level 4:SERIALIZABLE
