ConfigurableTransactionSupport SPIThe J2EE Connector 1.5 specification allows a resource adapter to use the "Transactional Support" attribute to specify From GlassFishV2, a ManagedConnectionFactory could implement an optional interface called ConfigurableTransactionSupport, to be notified by the application server to indicate the "transaction-support" configured for the pool. This setting would be done when the MCF instance is created for a pool. Please note though the application server would set the current configured "transaction-support" value of the connection pool, connections obtained from the connection pool could be used in a transaction level lower than the configured value. For example, a connection obtained from a pool that is configured as XA_TRANSACTION could be used as a LOCAL resource in a LAO transaction (or) a connection obtained from a XA_TRANSACTION pool could be used in a non-transactional context. package com.sun.appserv.connectors.spi; public enum TransactionSupport { NO_TRANSACTION, LOCAL_TRANSACTION, XA_TRANSACTION }; /** * An optional interface that could be implemented by a resource adapter's * ManagedConnectionFactory to be notified of the configured "transaction-support" * of the connection pool associated with the ManagedConnectionFactory instance */ public interface ConfigurableTransactionSupport { public void setTransactionSupport(TransactionSupport ts); } |
