Examples of TransactionParticipant

com.sun.sgs.service.TransactionParticipant

This interface is used by participants in transactions. Typically, each implementation of Service will either implement TransactionParticipant directly, or use some proxy as their participant. Classes that implement TransactionParticipant must also implement Serializable.

Note that the general model assumes that Services will use each other during a transaction. For instance, most Services will use the DataService to persist data. However once the transaction begins to prepare or is aborted (i.e., once any of the methods defined here are called on a participant), a Service may not interact with any other Service in the context of that transaction. Doing so results in unspecified behavior.

This interface does not specify how transaction participants learn the outcome of prepared transactions following a crash. Doing so requires a separate interaction between the participant and the transaction coordinator that is not specified by this interface. Without that additional communication, this interface is sufficient to support transactions with at most one durable transaction participant. @see NonDurableTransactionParticipant

net.jini.core.transaction.server.TransactionParticipant

The interface used for participants of the two-phase commit protocol. The methods on this interface are called by the transaction manager. Any class that wants to have operations wrapped in a transaction needs to support this interface. In conjunction with the TransactionManager interface, this interface allows a two-phase commit protocol to be used between objects in a distributed system. @author Sun Microsystems, Inc. @see TransactionManager @see NestableTransactionManager @see ServerTransaction @since 1.0
