Tengah also supplies transaction services, as specified by Enterprise JavaBeans. If a transaction failed during execution, the transaction would be rolled back to the point where the initiating system could resynchronize its data and try again, says Scott Dietzen, vice president of Web Logic. Coincidentally, the Athena spreadsheet engine is being tested on the Tengah application server and makes use of the transaction rollback and recovery service instead of including it in JavaBeans. The Enterprise JavaBeans specification will create a neutral playing field and allow systems from different vendors to work together in executing transactions, he says. With such an approach, application developers could turn to a readily available supply of components and use them to accomplish their application's task.
Components are the basis for all future applications.
