If there is no active tx, it begins a new tx whose scope is same as the scope of this tag. Whether the new transaction is rolled back or committed depends on if there is any exception or not. It optionally makes available the UserTransaction object in a request scoped variable whose id is supplied by caller. com.sun.jpatl.TXTag id false String Name of the output variable com.sun.jpatl.TXTag$ExtraInfo injectDefaultPU This tag can be used to inject a default persistence unit into a JSP. The injected persistence unit is made available in a page scope variable whose id is required to be supplied by the caller. Note the type of the injected variable is EntityManagerFactory. com.sun.jpatl.InjectDefaultPUTag id true String The name of the PAGE scope variable that will hold reference to the injected EntityManagerFactory empty com.sun.jpatl.InjectDefaultPUTag$ExtraInfo injectDefaultPC This tag can be used to inject a default persistence context into a JSP. The injected persistence context is made available in a page scope variable whose id is required to be supplied by the caller. Note the type of the injected variable is EntityManager. com.sun.jpatl.InjectDefaultPCTag id true String The name of the PAGE scope variable that will hold reference to the injected EntityManager empty com.sun.jpatl.InjectDefaultPCTag$ExtraInfo createPC Creates a new stanadalone PersistenceContext. By default it creates TRANSACTION scoped PC. com.sun.jpatl.CreatePCTag emf true String Name of the variable holding reference to the EntityManagerFactory to be used for creation of the PC. type false String Can be either TRANSACTION (default) or EXTENDED. id true String Name of the output variable empty com.sun.jpatl.CreatePCTag$ExtraInfo persist persist an object in database com.sun.jpatl.PersistTag em true Name of the variable holding reference to an EntityManager object Object true true the object to be persisted empty remove remove an object from database com.sun.jpatl.RemoveTag em true Name of the variable holding reference to an EntityManager object Object true true the object to be removed empty refresh refresh in memory object with state in database com.sun.jpatl.RefreshTag em true Name of the variable holding reference to an EntityManager object Object true true the object to be refreshed empty find find an object with given primary key com.sun.jpatl.FindTag em true Name of the variable holding reference to an EntityManager clazz true fully qualified name of the entity class String pk Object true true primary key id true Name of output variable empty com.sun.jpatl.FindTag$ExtraInfo
