Method Detail

• getWorkManager

  WorkManager getWorkManager()

  Provides a handle to a WorkManager instance. The WorkManager instance could be used by a resource adapter to do its work by submitting Work instances for execution.

  Returns:

  a WorkManager instance.

• getXATerminator

  XATerminator getXATerminator()

  Provides a handle to a XATerminator instance. The XATerminator instance could be used by a resource adapter to flow-in transaction completion and crash recovery calls from an EIS.

  Returns:

  a XATerminator instance.

• createTimer

  java.util.Timer createTimer()
                       throws UnavailableException

  Creates a new java.util.Timer instance. The Timer instance could be used to perform periodic Work executions or other tasks.

  Returns:

  a new Timer instance.

  Throws:

  UnavailableException - indicates that a Timer instance is not available. The request may be retried later.

• isContextSupported

  boolean isContextSupported(java.lang.Class<? extends WorkContext> workContextClass)

  A resource adapter can check an application server's support for a particular WorkContext type through this method. This mechanism enables a resource adapter developer to dynamically change the WorkContexts submitted with a Work instance based on the support provided by the application server. The application server must employ an exact type equality check (that is java.lang.Class.equals(java.lang.Class) check) in this method, to check if it supports the WorkContext type provided by the resource adapter. This method must be idempotent, that is all calls to this method by a resource adapter for a particular WorkContext type must return the same boolean value throughout the lifecycle of that resource adapter instance.

  Parameters:

  workContextClass - The WorkContext type that is tested for support by the application server.

  Returns:

  true if the workContextClass is supported by the application server. false if the workContextClass is unsupported or unknown to the application server.

  Since:

  1.6

• getTransactionSynchronizationRegistry

  TransactionSynchronizationRegistry getTransactionSynchronizationRegistry()

  Provides a handle to a TransactionSynchronization instance. The TransactionSynchronizationRegistry instance could be used by a resource adapter to register synchronization objects, get transaction state and status etc. This interface is implemented by the application server by a stateless service object. The same object can be used by any number of resource adapter objects with thread safety.

  Returns:

  a TransactionSynchronizationRegistry instance.
