Manipulating synchronization of entity beans and datastores

You can indicate that a particular Enterprise JavaBeans (EJB) type should not synchronize its state to persistent storage prior to each findBy invocation by using environment variables or a marker interface.

About this task

There are two options available for indicating that a particular EJB type should not synchronize its state to persistent storage prior to each findBy invocation:
  • Set an EJB environment variable within the bean's deployment descriptor
  • Have the bean implementation class implement a marker interface. This second technique is especially useful if you have a number of bean implementations that all extend a single root class; in this case you can have the root class implement the marker interface, causing all beans that extend this class to inherit the behavior as well.
