What is the difference between the Registry class and Naming class.
In my application I am using Registry class. But I want to know about Naming class and its uses ?

I'm missing something about the difference between
- starting rmiregistry at the command prompt (separately from whatever Java process is running a server that implements an RMI interface)
- having the server call

Hello, I'm still new to RMI, and I have one question. Each server process can support its own registry, or can have a single stand-alone registry that supports all the Virtual Machines on a server node. I know you start a registry using the rmiregistry, but how can I start for a particular server node as I just mentioned? Thanks |

Hi, when I invoke rmiregistry from command line (Win'NT) i am getting following exception. Apparently Naming.rebind is failing. (All programs including rmid, rmiregistry, RMI activation setup program are running on local host). Strangely, If I create rmiregistry programatically, then it is working. After going through the API documentation, I notice that LocateRegistry.createRegistry() creates as well as EXPORTS Registry. What is meant ... |

"Birmingham city" - Please take a moment to review JavaRanch's naming policy, and change your name accordingly; thank you. The code above locates an RMI registry on the local system. The list() call normally returns a String[] of named services already bound to the registry. In this example the return value is ignored, so perhaps it's invoked to provoke a possible ... |

Hi, I learn from the RMI documents that the client, RMI registry and remote objects can be in 3 different machines. But I searched the web but could not find any real case of this. All tutorials and examples are doing the registry+remote objects in one machine and the client in another (or all 3 in 1 machine). Did anyone really ... |
Hi, I have a code tht uses RMI.It is a creditcardprocessormodule thtis activated by a timer at a particular time and this module calls the creditcardprocessor class tht does the creditcard authorization.Ihave a bat file one for the creditcardprocessor to reigster it with the registry and the other for the creditcardprocessormodule to register to registry.However the creditcardprocesssor module cant find the ... |
If by "server" you mean your Remote object reference... you can always just create a new object of the correct type and use Naming.rebind(). Cleaning up references and resources used by the old reference and transferring them to the new reference could be a pain, though... what exactly are you trying to do? |
Hello Folks, I have one application which is looking up for a remote object (which itself calls and finds other objects) in the rmi regisrty on machine A port 1099. My question : Does rmi registry interfere in any other call after looking up the main remote object? Second question: since I set the rmi to communicate over any available port ... |
The port will not be release until the application has exited. And that, my friend, cannot be changed, as far as I understand. However, the registry will no longer accept method requests (like bind, list or lookup). Likewise, after unexportObject, you can create another registry listening on the same port and there will be no problem, as long as you do ... |
I am new to RMI;What is the difference between the Registry and naming services for lookup? I see examples that do: Registry registry = LocateRegistry.getRegistry(RemoteInterface.REGISTRY_PORT); RemoteInterface remoteReference = (RemoteInterface) UnicastRemoteObject.exportObject(new Server()); registry.rebind(RemoteInterface.REGISTRY_NAME, remoteReference); as well as examples that do : AccountImpl acct = new AccountImpl("JimF"); // Register it with the local naming registry Naming.rebind("JimF", acct); So what's the difference in binding ... |

Hi Amirtharaj, the rmiregistry tool is indeed a simple JNDI service provider. It's probably not as powerful as "real" JNDI services with LDAP backend or something like this but according to Sun it at least offers the JNDI interfaces. Generally I think there's no problem to run rmiregistry in parallel to JBoss on the same computer. But by default they both ... |

Hello I've got one question. I'm using Java RMI for programming my distributed application. I have one server which is registered in the registry and sometimes I shut down my application incorrectly (I don't unbind this server from the registry) After it, I run the client, which finds the server's reference in the registry, but when it wants to call some ... |

I have just finished writing my first project which uses RMI. However, although I am sure my code is correct, I cant test it/use it as I am not sure how to start the RMI registry. At university I was told to open a command window, go to the directories holding my class files and start the registry by typing "start ... |
is there a way to check if RMI registry is already running? In my case i solved by using a static flag that is checked before the "java.rmi.registry.LocateRegistry.createRegistry(1099);" code to prevent other instances of the same class to try to start it again (only the first will be able to start it). I think another way would be to catch the ... |
