Crazy Exception blocked my RMI server

Hi all one crazy exception is thrown when I try to start the server. Plz reply me the the possible cause and solution.
thanks in advance
The exception is :
Error starting service
java.rmi.server.ExportException: Listen failed on port: 0; nested exception is:
java.net.SocketException: JVM_Bind (code=10055)

You cant listen / bind on port 0. Try a different port number greater than 1024. That should work out.

Strange unmarshalling exception when starting RMI server

I've run into a strange problem when running my RMI server. It worked fine yesterday, though I made a few changes since then, none of those changes should cause this to happen, as far as I know.

pub.interfaces.ClientIface is in the SAME directory as the RMI server class! What could be causing this?
NOTE: I'm running this on Redhat Linux 9, jdk 1.5.0_04.

Usually an unmarshalling exception is caused by the classes not matching up on the server & client end. The classes are there I think, because otherwise it would have thrown a classnotfound exception instead. Can you try actually copying and pasting the classes either from the server to the client or vice versa? I've had weird issues where sometimes the compiler compiles the same class differently in different locations, so your safest bet is to make sure the client & server classes (that you're passing as arguments & returning from the server) are identical.
Good luck!

Java.rmi.server.SkeletonMismatchException: interface hash mismatch

I am trying to get a MBORemoteSet from the session, which actually gives me the list from the database table. when i click on a combo box returning me the list using the MBOSetRemote object it throws me the exception.

Well this error occurs if the RMI files are different on the server and client side.
It basically tells you that the stub and skeleton don't match with each other. Get the latest version of the RMI jar file or whatever file you are using on the server side to replace the file you are using oon the client side. This would make stub and skeletons to communicate with each other effectively . enjoy :)

Regular RMI server object with WebLogic JNDI

Is that possible to register a regular RMI object with WebLogic JNDI
tree? I was building a simple program (using javac and rmic only) based
on the java.rmi.* (without changing the import statements to
weblogic.rmi.*) and using the weblogic.jndi to register the server
object. Below is some piece of code,
Context ctx = null;
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL, "t3://172.20.20.20:7001");
ctx = new InitialContext(ht);
ctx.bind("HelloServer", obj);
The code failed for the following reason,
javax.naming.NamingException. Root exception is
java.rmi.MarshalException: failed to marshal public abstract void
weblogic.jndi.internal.NamingNode.bind(java.lang.String,java.lang.Object,java.util.Hashtable)

exception is:

Java.rmi.server.ExportException...

I am making a bridge code.
the server is in a package called bridgeserver.
The client in a package called bridgeclient.
I have compiled all files in the packages.
I do rmic bridgeserver.BridgeServer(name of server program) from jdk1.3
I do c:\jdk1.3 >rmic bridgeclient\BridgeClient(name of client).
then start rmiregistry
then when I do java bridgeserver.BridgeServer(runnign thr server) I get the follwowing exceptions:
java.rmi.server.ExportException : Unable to access remote reference,
nested exception is
java.rmi.server.SkeletonNotFoundException:
Skeleton class not found :bridgeserver.BridgeServer_Skel;nested exception is ;
java.lang.ClassNotFoundException :bridgeserver.BridgeServer-Skel
Is there sometyhign wrong with the classpath?

on your rmic line include the option
-v1.2
This should get rid of skeleton junk. (But of course may uncover other problems.)

RMI server and client in one application - Exceptions during some calls

I wrote an application, which is an RMI-Server (Server1), and another separate application, which is an RMI-Client (Client1). Because I wont use dynamic class loading, I gave the client beside the interface.java also an interface_implementation.java, which is only a dummy of the original interface_implementation of the server. This dummy contains only declarations of the methods (parameters and return values) and no functional code. From this dummy the _stub.class is generated, and it works fine - no problem.
Now I want to modify Client1 to become also an RMI-Server (Server2) for a second, separate Client (Client2), the methods used are different from the first RMI connection. This Client2 uses a dummy of the implementation of Server2 in the same way as described above. The application Client1+Server2 only has to "translate" the calls from Client2 to Server2 into calls of Client1 to Server1 (Server1 is not changed at all). In case of primitive method parameters or return values this chain of RMI-applications works fine, but in case of more complex structures (my own classes) during the call of Client1 to Server1 an "ClassNotFoundException: access denied to class loader" occurs by running through the stub. Both stub.classes are found, all of the applications know the objects needed, the call of Client1 to Server1 is exactly the same call as it was during the simple version (only Server1 and Client1).
Does anybody know, why this exception occurs and how I can overcome this ?
Axel

I figured out a solution - it's a problem of policies. In detail: Server1's codebase entry (file:) refers to the class directory of Server1's project. In the simple case of only Client1, which has no codebase entry, it works fine without a file permission on the side of Server1. In the complex case of Client1+Server2, which has to have a codebase entry (file:) refering to the class directory of the Server2's project on a separate machine, for exactly the same method call from Client1 to Server1 a file permission entry on the side of Server1 is needed for Server1's class directory. But WHY ???
It seems to be a little confusing with the codebase entries, many of the posts are contrary to others and to my personal experiences. Some comments given by Adrian Colley throw a little light upon some aspects. Is there anybody, who can explain the whole topic, when, why, and which part of RMI application deals with codebase entries, also in case of not dynamic code downloading ? May be there is also a reference into the java docs, which I didn't found up to now.
Thanks in advance

Raising new Exception within RMI server

hi all,
i implemented an RMI server which, in one of his method, throws my custom exception.
Since my RMI server is loading classes dynamically, i grabbed all those exceptions that comes when a class cannot be loaded in an MyClassNotLoadedException
in my code i write the following lined
try {
MyClass example = (MyClass)class.forName("MyClass").newInstance();
} catch(Exception e) {
throws new MyClassNotLoadedException(e);
when i am running my test client, i always got the following exception:

can anyone help me?? is it so that every exception that i raise in my RMI server must
extends RemoteException??
hope that someone can help me
thanx in advance and regards

Don't need to extends RemoteException. But have you defined your
Exception that is implements Serializable?
public class YourException extends Exception

RMI-server communicates oracle: Exception

Hallo everybody,
My task is:
- to implement in oracle Java stored procedure,
- to implement RMI server
- to load in oracle wrapper for Connection-object (ConnectionImpl), that has a reference at Connection (default oracle Connection), this ConnectionImpl-object will be passed to RMI-server, the RMI-server will call a method on this object.
- Stub and Skeleton of ConnectionImpl are on both sides available (inside of oracle (as .jar) and on RMI-server side).
First I start RMI-server. Then I call the stored procedure. It finds RMI-server, calls the method on RMI-server side, then RMI-server tries to call the method of ConnectionImpl with the following result:

I will be thankful for every tip, how I can resolve it.

Its clear you have the java permission set to allow db Java to write to a socket, since the call to the RMI server works, but maybe you are missing the permission to allow db java to listen and/or read from a socket?
See:

My RMI Server application Not work under Linux: Exception: Connection reset

Under Red Hat Linux 8.0 my RMI server application, when I try to bind the Impl class, sends me the exception:
"java.rmi.UnmarshalException: Error unmarshaling return header;
nested exception is: java.net.SocketException: Connection reset".
And it works under Windows 2000 without any problem.
What could it be?
Many thanks,
Ales.

Hi Ales,
Try to change your /etc/hosts file, and change the line that says :
127.0.0.1 MDK localhost.localdomain localhost
(where MDK is the machine's name).
Remove MDK from this line and add a new one mapping it to a 'real' outside IP address, visible (check firewall!!!) to the network from where you are approaching the Linux Box
Good luck,
Aart

Why constructor of rmi server throws remote exception

why is it that the constructor of the class extending UnicastRemoteObject i.e rmi server has to throw RemoteException?

Writing an RMI server is a matter of defining a class, exporting it when constructed and implementing one or more remote interfaces. How to export?
auto export happens when u call super() in the constructor. It is then registered with the rmi system and made to listen to a TCP port. The various constructors for UnicatRemoteObject allow the derived classes to export at the default port.
Because this automatic export step occurs at construction the constructors throw this exception.

PS:Sorry for my spaghetti-english :D

I had similar issue and i got rid of it by doing the following:
i. Start rmiregistry from the server code (so that the JVM remains the same) like this
// Server.java
Process pro = Runtime.getRuntime().exec("rmiregistry 1099 &");
// ... ii. Use java.rmi.server.codebase property while starting the server
D:\rmiEx\bin>java -Djava.rmi.server.codebase=file:/D:\rmiEx\bin example.hello.Server

RMI Server Basic Problem

Hi,
I have a special problem for which I have no idea at the moment how to solve, although I am pretty new to RMI.
I get this error message
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: rmikochbuch.RemoteDateImpl_Stub
when I try to start an executable jar-file.
What I have is:
On my development PC (Win2k WS) I run
java -jar RMI_Server_Test_01.jar
(of course after "start rmiregistry") and it works. Now I take this jar file and copy it to two other PCs (Win XP / Win2k Server). So when I try to start my jar file on these machines too, I get the error messages you see above. All three machines have the same SDK 1.4.2_07 installed.
I have neither an explanation why it does not work on the other machines nor do I have any idea how to solve this problem. :(
Additional info:
The error message occurs in this code block:
      RemoteDateImpl im = new RemoteDateImpl();
      System.out.println( "DateServer starting..." );
      Naming.rebind( RemoteDate.LOOKUPNAME, im );The "DateServer starting..." gets displayed but then the program crashes and exits.

Got this problem solved now.
What I had to do - and this is not mentioned in the Java cookbook (O'Reilly):
Copy the Interface, the Implementation plus Stub + Skel .class files to the CLASSPATH on the server.
Now comes the second part - connect from a client to this server...

Any ideas, I am going crazy I have cjecked the paths individually using another command prompt and it is fine. Advice???

Please check that your program can find all necessary classes. It looks like your application is missing some classes. Check the "visibility" of your classes, their names etc. (public MyClass ..)
As the error says no class found... if you are using "package"-keyword please check that you are importing right classes from packages.(import packagename.YourClass...)
