EJB 2.0 Development with WebSphere Studio Application Developer

Remote and local interfaces: comparison

Figure 2-26 compares remote and local interfaces.

Figure 2-26. Comparison between remote and local interfaces

Figure 2-27. Client lookup of local home interface

InitialContext ctx = new InitialContext(); Object objHome = ctx.lookup("java:comp/env/ejb/itso/MyCustomer"); CustomerLocalHome home = (CustomerLocalHome)(objHome);
