Hello all! We are developing an Orion-based system. In short, there are three beans: GameSession (stateful session bean), GameMachine and UserData (CMP entity beans, pure data with almost no logic). All methods in the beans have Required transaction attribute in deployment descriptor, there is an CMT datasource set up (as a wrapper to PostgresqlDataSource).
When I call the business methods of the GameSession bean (usually from a servlet), it seems(from the database log) that the calls to entity beans are not encompassed in a transaction, but start their own transactions. Moreover, this results in multiple updates to the database (I think one call to ejbStore() for every setter call), causing everything to run quite slow. The ejbLoad is called only once, though. What I am doing wrong or what else should I do to make it work in single transaction and single ejbLoad/ejbStore call? -- Best regards, Grzegorz mailto:[EMAIL PROTECTED]
