Detailed Description

This is the implementation of the XAResource interface for our pseudo JDBC-XA driver. This object is used to demarcate the transactions and associate an XID to the SQL requests (start-end). Actually, no real 2PC is done here because the std JDBC driver do not support a java XA interface for it (only commit/rollback but no prepare!) So we choose to return always OK at prepare. The goal is more to offer a standard JDBC-XA interface to the EJB Container than to achieve a real distributed 2PC. Anyway, when database vendors will offer real JDBC-XA drivers, the JOnAS Server will be OK without any change.
