Member Function Documentation

synchronized void org.objectweb.jonas_ejb.container.TxListener.addInstance (  JEntityContext  ec  )

Add a new Context in the list. Parameters: ec  the JEntityContext to synchronize Definition at line 93 of file TxListener.java. Referenced by org.objectweb.jonas_ejb.container.JEntityFactory.registerContext().

void org.objectweb.jonas_ejb.container.TxListener.afterCompletion (  int  status  )

The afterCompletion method is called by the transaction manager after the transaction is committed or rolled back. This method executes without a transaction context. Parameters: status  The status of the transaction completion. Definition at line 134 of file TxListener.java. References org.objectweb.jonas_ejb.container.JEntityContext.afterCompletion(), and org.objectweb.jonas_ejb.container.JEntityFactory.removeTxListener().

Here is the call graph for this function:

void org.objectweb.jonas_ejb.container.TxListener.beforeCompletion (   )

This beforeCompletion method is called by the transaction manager prior to the start of the transaction completion process. This method executes in the transaction context of the calling thread. The Bean's state must be stored on the persistent storage before the completion of the transaction. Definition at line 114 of file TxListener.java. References org.objectweb.jonas_ejb.container.JFactory.myClassLoader(), org.objectweb.jonas_ejb.container.JFactory.resetComponentContext(), org.objectweb.jonas_ejb.container.JFactory.setComponentContext(), and org.objectweb.jonas_ejb.container.TxListener.storeInstances().

Here is the call graph for this function:

synchronized void org.objectweb.jonas_ejb.container.TxListener.storeInstances (   )

Synchronizes all instances on disk. This must be called before every SQL request (finder) or at beforeCompletion(). We must be in the good transaction context here, and with the correct component environment (java:comp). Definition at line 75 of file TxListener.java. Referenced by org.objectweb.jonas_ejb.container.TxListener.beforeCompletion(), and org.objectweb.jonas_ejb.container.JEntityFactory.syncForFind().
