IBM Press, Contents 1. The only catch is that this is only supported within standard Java EE components or containers that are compliant to the JPA container contract , so this example uses a stateless session bean. Listing 5 shows methods that perform these operations.

Also, an update does not even involve invoking the entity manager, but requires reading the pet, loading it into the entity manager and then modifying it. The modification will be reflected in the database when the transaction is committed.

Java Persistence

The merge method can also be used to create entities, but is most useful for merging in entity changes made on the client side. Section 5 Transactions Since we just mentioned transactions, but didn't explain them, now would be a good time to state that JPA supports two different kinds of transactions.

JTA container transactions Used when running in container mode resource local transactions Typically used when running in non-container mode. For example, if the methods in Listing 5 were in a session bean that had a Required transaction attribute setting then a transaction would be started at the beginning and committed at the end of each client method invocation. When using local transactions the transaction must be demarcated manually by invoking on the EntityTransaction instance accessed from the entity manager.JavaScript is currently disabled, this site works much better if you enable JavaScript in your browser.

It covers entities, identifiers, O-R mappings, using an entity manager, creating and executing queries, and configuration of the persistence. The Vietnam of Computer Science. Use DAO layer accept limitations while working to reduce them know when to stop trying to reduce them!

Defaulting rules in JPA mean that you are not required to specify table names and column names that an entity is mapped to.
