My question is: how can i deploy session bean on Computer A and Deploy Servlet or JSP on Computer B? It mean Computer A have Session Bean Source and Computer B have Servlet or JSP source. if use 1 computer i can use @EJB dependency inject lookup Session Bean but on another computer how can i do it for client code? Example for 1 computer

Answer 1

1. Create a "client jar" with the remote interfaces, deploy in on the client

2. Provide the app server client jar (not necessary in your scenario)

3. Provide a jndi.properties on the classpath with the following content (assuming GlassFish to GlassFish communication):

   java.naming.factory.initial=com.sun.enterprise.naming.SerialInitContextFactory
   java.naming.factory.url.pkgs=com.sun.enterprise.naming
   java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl
   org.omg.CORBA.ORBInitialHost=<hostname>
   org.omg.CORBA.ORBInitialPort=3700
   

4. Use the mappedName attribute of the @EJB annotation to specify the global JNDI name of the target Remote EJB component (If there is no jndi-name set in sun-ejb-jar.xml - or no sun-ejb-jar.xml at all - the global jndi-name defaults to the fully qualified Remote 3.0 Business interface class name) :

   @EJB(mappedName="com.acme.app.StatelessRemote")
   private StatelessRemote remote;
