Java IDL Code Samples

Print-friendly Version

Java IDL is a CORBA-compliant technology for distributed objects that lets objects interact regardless of whether they are written in the Java programming language or another language.

• CORBA Hello World Example
• File Transfer Example
• Portable Object Adapter Example
• Servlets Example

• HelloApplet.java is a CORBA Hello World applet. For supporting information see The Java Tutorial Continued: Java IDL.
  
  
• HelloClient.java is a CORBA Hello World application. For supporting information see The Java Tutorial Continued: Java IDL.
  
  
• HelloServer.java is a CORBA transient server. For supporting information see The Java Tutorial Continued: Java IDL.
  
  
• Hello StringifiedClient.java is a client that access the stringified object created by HelloStri ngifiedServer.java For supporting information see The Java Tutorial Continued: Java IDL.
  
  
• Hello StringifiedServer.java creates and stores a reference to a stringified object so a client can access it. The reference is written to the disk in the form of a text file. A stringified object is used when no naming service is available in the distributed environment. For supporting information see The Java Tutorial Continued: Java IDL.
  
  

• FileClient.java is the client program that looks up the server. For supporting information see Distributed Java Programming with RMI and CORBA.
  
  
• FileInterface.idl defines an interface in the OMG Interface Definition Language (IDL) for a file transfer operation. For supporting information see Distributed Java Programming with RMI and CORBA.
  
  
• FileServant.java implements the downloadFile method declared inFileInterface.idl. For supporting information see Distributed Java Programming with RMI and CORBA.

• FileServer.java implements a CORBA server that initializes the ORB, creates a FileServant object, registers the object in the CORBA Naming Service (COS Naming), prints a status message, and waits for incoming client requests. For supporting information see Distributed Java Programming with RMI and CORBA.
  
  

• AddClient.java implements a client that contacts and communicates with a server. For supporting information see CORBA Programming with J2SE 1.4.
  
  
• AddClient3.java implements a client to work with a persistent server. For supporting information see CORBA Programming with J2SE 1.4.
  
  
• Add.idl defines an interface in the OMG Interface Definition Language (IDL) for an addition operation. For supporting information see CORBA Programming with J2SE 1.4.
  
  
• AddImpl.java implements an IDL interface. For supporting information see CORBA Programming with J2SE 1.4.
  
  
• AddServant.java shows how to develop a persistent server where the objects outlive the process that created them. For supporting information see CORBA Programming with J2SE 1.4.
  
  
• AddServer.java implements a sample server that does such things as create and initialize the ORB, and create an instance of the the interface and registers it with the ORB. For supporting information see CORBA Programming with J2SE 1.4.
  
  
• AddServer3.java implements a persistent server. and create an instance of the the interface and registers it with the ORB. For supporting information see CORBA Programming with J2SE 1.4.
  
  

• Arith.idl defines an interface in the OMG Interface Definition Language (IDL) for a multiplication operation. For supporting information see Servlet Inter-Communication with CORBA.
  
  
• MathServer.java implemens the CORBA server to initialize the ORB, create a MultiplyServant object, register the object in the CORBA Naming Service (COS Naming), print a status message, and wait for incoming client requests. For supporting information see Servlet Inter-Communication with CORBA.
  
  
• MathServlet.java acts as a CORBA client by looking up the server. For supporting information see Servlet Inter-Communication with CORBA.
  
  
• MultiplyServant.java implements a multiply operation. For supporting information see Servlet Inter-Communication with CORBA.
