问题 This maybe too localized, but I am hoping someone can help me articulate my questions properly. So, we have a front end web server that communicates with a back end app server using CORBA. I have been asked to port the back end application to a LINUX box, which I did. But, in order to test it, I am trying to point the front end web server to the LINUX back end. We are using omniORB-4.1.4, and here is how the instance of the back end system is obtained: String args[] = new String[0]; System

问题 JDK-11 will remove a lot of older parts of the JDK (JEP-320). For some of them (e.g. JAXB) functionality will be provided as regular library. You simply add another dependency and everything works fine again. But not so for CORBA, because There is no significant interest in developing modern applications with CORBA in Java I am however in the painful situation of needing to maintain older applications that still require CORBA while still wanting to update to JDK-11. Is there a replacement

问题 I have been trying to use Java EE 6 to create an Application Server based app which is to receive Job objects from a GWT Web Application and those Jobs would be pulled from a Java stand-alone application. I have been thinking that the EJB model would provide me with easy way to do remoting because my client app should be able to run on a different machine. I am using Glassfish 3.1 and Netbeans 7.0.1 as my IDE, I have also used eclipse Java EE to reproduce same problem. I have been facing the

问题 We are currently using MICO to establish the communication between a server and a client, where the client is a simulator written in C++ and the server is a java program displaying an animation of what happens in the simulation. It seems that the developemt of MICO has slowed down to an almost halt and bugs that only allow us to hack around them (as we don't have the time to first figure out which parts of MICO are responsible for codegeneration and so on) keep us from making real progress.

问题 I have a class: class Impl1 : public POA_I1 { private : Impl2_var ob; public : Impl2_ptr get(); { return ob; } void set(::Impl2_ptr ob) { this->ob = ob; } }; I'm a litte bit confused about _ptr and _var . I read that MyObject_var The _var version of the object reference type acts as a handle toproxy in much the same way as a _ptr reference but also adds memory management. Like all _var types, a _var reference takes care of deallocating its underlying instance (in this case, the proxy instance

问题 am new to corba and also am using eclipse ide for running it. whenever am running the server the following error message is coming Dec 15, 2012 9:17:18 AM com.sun.corba.se.impl.protocol.giopmsgheaders.MessageBase readGIOPHeader WARNING: "IOP00710220: (INTERNAL) Error in GIOP magic" org.omg.CORBA.INTERNAL: vmcid: SUN minor code: 220 completed: Maybe at com.sun.corba.se.impl.logging.ORBUtilSystemException.giopMagicError(Unknown Source) at com.sun.corba.se.impl.logging.ORBUtilSystemException

问题 I have application in CORBA using IIOP protocol, i am using the Java IDL component of the JDK 6 , another ORB implementation. Implementation of both client and server in Java language. Is there any way in the JDK ORB implementation to get the client ORB`s host and port from the server (ORB)code ? Or is there any way with use of IIOP protocol, get client the host and port ? This is we are doing for identification of the client to track the who is requested 回答1: I don't think there is any

问题 I am developing a client server application where i can invoke server from the remote client and the some string is returned from the client. I am using CORBA . I have a user interface developed by using Java Swing on Netbeans . I need to invoke the server when a button is clicked on the client interface. For that I have to put following code segment inside jButton action listener. private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { try{ // create and initialize the ORB ORB

问题 I'm developing a project in which I need to implement a Chat server in C++ and Chat clients in Java using swing for implementing the GUI. I'm having exactly this problem, implementing nearly the same project: Segmentation fault CORBA C++ This is the part of my IDL where the problem is: typedef sequence<ICliente> ListaClientes; interface IServer { attribute ListaClientes lista; void registrar_usuario (in ICliente cliente) raises (usuarioRegistrado); IConversacion crear_conversacion (in
