Rmiregistry

Hi @all,
after a few hours my program gets a
"java.rmi.ConnectException : Connection refused to host"
or
"java.rmi.ConnectIOException : error during JRMP connection establishment"
while trying
Naming.lookup(rmi://....)
Is it possible that the rmiregistry crashed or can't the rmiregistry be the reason?
Thank you

Hi there,
just trying to clearify the question: you said "after a few hours", do you mean that your program was running, but crashes without you doing any thing to it?

Rmiregistry crashing Java HotSpot VM on SGI machine

Hello!
I have created an application that uses RMI in Java to pass messages between one server and several clients. That is, the clients talk only to the server and not with each other. I've recently been tasked by my company to make this program work an an 8-processor 64-bit machine.
I originally thought that it must have been something wrong with the code, seeing as how it was created on a Windows 32-bit machine, and now I'm trying to run it a Unix 64-bit machine. In fact our technology expert suggested that it may be ENDIAN issues... However, I've just about tracked down the problems I'm having to the rmiregistry.
I think it is causing these random HotSpot VM crashes I've been having. The biggest reason I suspect this is because upon typing
rmiregistry&
in the console window, I have been able to get one of those crashes. This is before I have any code running, and yes, my path variables are set correctly and also my policy file is set to the correct path.
Does anyone have any ideas? Thanks!

At very first moment, I haven't used jdk from arch repo,
so i was downloaded it from java.sun.com.
and haven't any problem jdk1.5.0 or 1.6 with Eclipse, though i didn't tried Azureus.
PS: so my jdk-1.6.0 is under home directory.

Error with "rmiregistry" in command prompt

Hello everybody.
I am experiencing something really strange. I am doing the exercices on http://java.sun.com/developer/onlineTraining/rmi/RMI.html#RMIArchitectureGoals and now am trying the second one.
When I type in "rmiregistry" in command prompt at location "C:\" it's works fine. However, when I type it in "C:\JProg\RMI" (and for another program a subdirectory) where my classes reside, command goes all funny. It keeps printing the command-line without any results.
I tried to use it anyway but then I get a "Connection refused to host: localhost" error, so it really doesn't work.
I also tried the all the above ten times at least.... it is consistent.
Does anybody have any idea what the hell command is on about ?
Thanks,
Q

"rmiregistry" in command prompt is just registering
into the registry. No output or response will be
resulted. The next line cursor will be appeared. That
all. If any error has, you should check the class
again I mean related coding.I do not understand what the classes have to do with the rmiregistry command. When I create an empty directory it works, that is: it gives a blinking _ and I can succesfully start a server class. How can this problem (which occurs before calling any classes) have anything to do with the classfiles ? It is only in my RMI (and sub-) directory that the rmiregistry goes all wacky.

How to change the classpath in rmiregistry

I am storing remote object stubs in an RMI registry as part of my application. When I try to bind my objects to the rmiregistry started by the kxs process on port 1099, I get class def not found errors because that rmiregistry does not have my classes in the classpath. My classes are in the iAS classpath because I added them through the registry.
When I start my own rmiregistry on a different port and set the classpath environment variable to include my classes, then I have no problems.
Does anyone know how to change the classpath for the rmiregistry started by the kxs process?
I am running iAS sp3 on Windows 2000 adn Solaris

Rmiregistry: Port already in use error

Hi,
I'm running the following comand to start a registry service listening on port 1099. I'll start and stop it several times with control-C and everything will work fine but if I do this a few times, it will get to the point that when I try to start it again I get a message
saying the port is already in use(but I killed the service). Is there a way to start and stop the rmiregistry several times without it getting hung? I'm sure if you get into a production issue with this you need a way to get around it? Besides using the proper command, what can you do to free up a port? Note, I also noticed that netstat shows multiple entries listening on port 1099! Was this from re-trying the command when it failed or from the times that it was successful? Any help appreciated.
Thanks,
Peter

I have exactly the same problem. At first it was happening with the use of the "rmiregistry" command, but now my code creates the registry using registry = LocateRegistry.createRegistry(port) and I end up with the same problem.
I too end up with (typically) 3 listening sockets (as reported by netstat), that don't seem to be owned by any processes. So without a process to kill, the only way to get rid of them is to reboot.

How to unload/kill rmiRegistry if app was terminated abnormally

Hello,
I use the following method in coding to [1] launch the RMIRegistry to listen on port PORT, [2] Exports the remote object to make it available to receive incoming calls, [3] Bind the service name to the Registry
      int PORT = 1101;
      String HOST_NAME = "myHost";
      String SERVICE_NAME = "myRMIService";
      LocateRegistry.createRegistry( PORT );
      UnicastRemoteObject.exportObject( (MyRMIInterface)MyRMIObj );
      Naming.rebind( "//" + HOST_NAME + ":" + Integer.toString( PORT ) + "/" + SERVICE_NAME, MyRMIObj);However, If I the application was terminated abnormally and then restart the application, I always got the following exceptions separately (which I think the application will try to launch the RMIRegistry again and hence cause the following exceptions)

        ... 11 moreI don't know how to [1] free the RMIRegistry from listening on PORT and [2] also to terminate it from the background (it seems that RMIRegistry was executed in the Windows Task background).
Has anyone got any experiences on dealing with this issue?
Thanks in advance!

I would like to know what's the difference between
LocateRegistry.getRegistry(PORT) and
LocateRegistry.createRegistry(PORT)
It's all there in the Javadoc.
Can the "Registry"-type object be passed-to
UnicastRemoteObjecdt.unexportObject()?As it says in the Javadoc, Registry extends Remote.
'application terminated abnormally" means the
application was terminated by CTRL-C, or any
exceptions raised casuing the application to
terminate itself.I can only assume that you are catching some application exception and trying to restart the whole thing including the Registry from within the same JVM. If you are doing this and starting the Registry gives you 'ObjID in use' then obviously you don't have to start it.
If on the other hand the JVM containing the Registry and your application has completely exited, you can't get 'ObjID in use'.

How do I start "rmiregistry" from Eclipse IDE?

Could somebody tell me how I can start rmiregistry from the Eclipse IDE which is running j2se 5.0 ?
Also if I try starting from the command prompt I get
Windows cannot find rmiregistry
with
C:\>java -version
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)

You need a plugin to start/stop your rmi registry. Search for plugins in google.
You need to set the classpath for starting the rmi registry from console.

How can i know the location of rmiregistry throught the batch file ????!!!

i would make a batch file that launch my java application wich uses RMIREGISTRY, is there a way to know the path where is located the "rmiregistry file" -if it exists- in the client machine throught the batch file in order to start it befor to launching the application.?

Yes, ask the person who was responsible for making the RMI registry run.

How to stop rmiregistry through java coding?

Hi,
I don't know how to write java program to stop rmiregistry running on port 1099 ?
Could anyone please help me?
If possible please tell me the logic behind server shutdown program, like what we have in tomcat server, jboss etc.,
Thanks and Regards
Ram

hi,
Consider I'm working in the same JVM, I started rmiregistry using the command "LocateRegistry.createRegistry()". With respect to this scenario, please tell me how to stop the rmiregistry (say running on the port 1099)?
Thanks and Regards,
Ram

Why rmiregistry & Server must start in the same directory.

I have 2 servers & one rmiregisty for both. I want to start this servers separetely from different directories.
But if I try to start server from the directory other than where I've already started rmiregistry the server doesn't bind.
Please, can anyone explain why rmiregisty & server must start from the same directory?

Are you sure the classpath when rmiregistry is started includes jar/directories where rmiregistry can find your server stubs ???
rmiregistry does not need your implementation, but it needs your stubs to be able to register your server objects ...

BInd objects on non-local rmiregistry?

As I understand, every remote object should be registred on his own(local) rmiregistry.
I use JNDI like this:
/////////// Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.rmi.registry.RegistryContextFactory" );
env.put(Context.PROVIDER_URL, "rmi://localhost"); Context ctx = new InitialContext(env);
String rmiurl = "rmi://192.168.0.48/1.IObj";
Reference ref = new Reference("IObj", new StringRefAddr("URL", rmiurl)); ctx.rebind("JNDI_OBJ", ref); //////////
and this works out. But only with my local rmiregistry.
When I change PROVIDER_URL property I catch javax.naming.NoPermissionException. Is it possible to bind my objects on another rmiregistry.
I will be very appreciated, if you help me. Thank you.

The problem is the standard RMI initial context factory. With the standard RMI registry you are only allowed to bind to a local RMI registry. However you can use any Naming service to bind your object. This means you can use CAROL, JBossNS, or any other naming service of your liking. You just have to use the appropriate initial context factory in your initial context.

How can I avoid running rmiregistry when launch an RMI based application

Hi,
How can I avoid running rmiregistry when launch an RMI based application?

No Separate window for rmiregistry

Hi,
In my RMI application on Windows NT, I've written the server such a way that when it is run it would start the rmiregistry first of all and then the initialisation part. Here's the code
String [] cmd = {"cmd.exe","/c","rmiregistry"};
try
Process m = Runtime.getRuntime().exec(cmd) ;
catch(Exception ex)
ex.printStackTrace ();
When I run the server with this code to run the rmiregistry it opens up a separate command window. And that's exactly i don't want.
Is there any better way to do it. I want that rmiregistry should not open up separate window but run from within the server application window only.
Do suggest something...
Sunil.

It's a little hard to understand what you are doing and what you want just by an error message.
For starting the rmiregistry:
type 'rmiregistry' in a console box. It's an application located in your /bin/ directory of your JDK installation.
As for being unable to locate the RMI registry. I rather see you code on how you try to locate it, because just this error doesn't give me a clue what might be wrong. So, please post your code.. Use the '[ code ]' and '[ /code ]' tags please.

Is it possible to advoid running rmiregistry manually?

Hi,
Who knows whether it is possible to advoid running rmiregistry manually?
I've tried to use LocateRegistry.createRegistry() to do so.
But no avail.
I specify the policy file with -D switch and set the pemission properly but only to find:
java.rmi.ServerException: RemoteException occured in server thread; nested exception is:
Java.rmi.UnmarshlException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: access denied to class loader
Java.rmi.UnmarshlException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: access denied to class loader
java.lang.ClassNotFoundException: java.security.AccessControlException: access denied <java.io.FilePermission \.\- read>
<<no stack trace available>>

Hi,
the stack trace says it all: the security manager
applied does not allow to load classes. Did you
install your own security manager? You might have to.
Have fun,
