Example text

If you provide local interfaces to your Enterprise JavaBean, you get maximum performance, but at the price of location transparency: Your clients must be located in the same JVM as the Enterprise JavaBean instance. On the other hand, with remote interfaces, you can improve the performance by distributing the components among different servers. 4 JVM Local clients. Local Client JVM Remote Client Caution 41 EJB container Local Object Local Home Object Enterprise bean instance The calling semantics of local interfaces are different from those of remote interfaces.

The client looks up the EJB home object of the installed enterprise bean via Java Naming and Directory Interface (JNDI) services. The client then uses the home object to create an enterprise bean instance. However, the client isn’t given a direct reference to the newly created enterprise bean instance. Instead the client receives reference to an EJB object, an object of the component interface. The client then calls the EJB object, which delegates calls to the enterprise bean instance. 2 EJB Home object Client EJB object Note EJB Container Enterprise JavaBean under the hood.

Concurrency: Supports multithreading management. All components must be developed as single-threaded, and the container manages the concurrency and serialization access to the shared resources. • Resource pooling: Supports the allocation of a pool of instances, and then assigns them to the requesting clients. When an instance is free, it goes back to the pool. This is applied for JDBC connections, stateless session beans, and entity beans. Common Horizontal Services Common horizontal services are the services specified in the J2EE architecture.
