Rmic and java.rmi troubles

Hi
Have been trying to run the rmi calculator-example at http://java.sun.com/developer/onlineTraining/rmi/RMI.html, but keep getting:
Exception in thread "main" java.lang.InternalError: Unexpected exception while defining class CalculatorImpl
<<No stacktrace available>>
Caused by: java.lang.ClassNotFoundException: java.rmi.server.UnicastRemoteObject not found in [file:./, core:/]
<<No stacktrace available>>
when i do ">rmic CalculatorImpl"
Suspected at first that it was a classpath-problem. But using ">rmic -classpath c:\j2sdk1.4.2_05\lib CalculatorImpl" gave the same error.
Anyone know why I get this error?
regards

Sorry, my error, I didn't read your post closely.
Exception in thread "main" java.lang.InternalError: Unexpected exception while defining class CalculatorImplInternal Error = Thrown to indicate some unexpected internal error has occurred in the Java Virtual Machine.
VirtualMachineError =Thrown to indicate that the Java Virtual Machine is broken or has run out of resources necessary for it to continue operating.
I would have to take a wild guess and that wouldn't be fair to you. Normally I would congradulate you on breaking the JVM but I don't suppose you're ready for that yet.

Weblogic.rmi and java.rmi

Hi,
I would like to use weblogic to access a java object on another machine that
is using java.rmi. I am using the java "rmiregistry" on the non weblogic box.>
How can I write a java program that maintains state to that object at weblogic
startup and call it with a weblogic client?
Thanks

Rebind Method and java.rmi.server.hostname

Hello,
We are trying to execute a server on the internet which is installed in a machine whose private IP address is 10.X.X.XX.
To access the server by internet, the IP address is 196.XXX.XXX.XX and is converted by NAT to the IP address 10.X.X.XX.
I start the server with the command:
java -Djava.rmi.server.hostname=196.XXX.XXX.XXX myServer
Also, and according some recommendation in this forum, we don't use the "rmiregistry" and instead we use the method:
Registry r = LocateRegistry.getRegistry(MYPORT);
r.rebind("MyServer", obj);
However,
And it takes about over 4 minutes for this app to execute the rebind method. Does anyone know why ?
If I start without java.rmi.server.hostname propert. it executes immediatelly, but then I can't access the server from outside firewall.
Am I missing something?
Any advice or idea?
Thanks
Gerardo
PS. I am using Java 1.4.1 under Linux Red Hat 9.0.

I start the server with the command:
java -Djava.rmi.server.hostname=196.XXX.XXX.XXX myServerThe wait is probably due to your DNS setup. Is a client inside the firewall able to reverse-resolve a 196.xxx.xxx.xxx address?

Java-rmi.exe

Hi,
I have client (applet) server (RMI) system that needs to work through a firewall.
Everything i have read says that there is a java-rmi.cgi and java-rmi.exe files in the bin dir of the JDK. I have jdk 1.3.1.1 installed and could not find it. I downloaded JDK 1.2.1 and that didnt have it either. I found that jdk 1.1 did have the java-rmi.cgi file but now i dont know how to use it properly.
I am running a windows server with IIS 5 and am not sure how to configure it to run cgi. Maybe i should find the exe version? Where is it?
Cheers
Stew

It is java-rmi.cgi or java-rmi.exe depending on the platform. Instructions are given in the JDK. However this is for RMI/JRMP. This is the RMI/IIOP forum, and java-rmi.cgi doesn't work for RMI/IIOP.

Trouble: java.rmi.ServerException:

Hi all,
I tried to execute the example given in Sun tutorial.
I am getting the following error
Trouble: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: CalculatorImpl_Stub
Thanks

Hi,
This exception means the client attempted to download a stub from the server and couldn't find it.
You can get this exception for a variety of reasons:
1) The server-side doesn't have the stub. This is done by running the rmic tool against the implementation of a remote Interface
2) The server doesn't store the stub where the client can find it. This may be due to setting the System property java.rmi.server.codebase incorrectly, or not at all.
3) The server doesn't serve ("export") the stub. The server must have rmiregistry runnning on the server, and must make sure the rmiregistry CANNOT see the exportable object via its CLASSPATH.
3) The client is looking in the wrong place for the stub.

Trouble in storing and retrieving RMI object in Weblogic 7 JNDI tree.

I have created a simple server (BankImpl), implementing a RMI interface
called Bank. A stub class (BankImpl_Stub.class) is generated from BankImpl
class using
"rmic -v1.2". Then I bind an instance of the BankImpl class to the JNDI tree
in Weblogic
server 7 under the name of "PeopleBank".
After the binding, I can see the stub class in the JNDI tree, but with a
different name: BankImpl_WLStub.class). when a
client program is trying to lookup the stub associated with "PeopleBank", it
failed with a puzzling message:
java.io.NotSerializableException: BankImpl_WLStub
Why a stub of a RMI object is not serializable? Does Weblogic needs a
different rmic to generate RMI stubs?
Thanks,
Lian

Question about Java RMI and Eclipse

I would like to create an application with which I can easily connect to a JAVA program, installed on a web server, through JAVA RMI. I have already created a ClientRMI.java and a ServerRMI.java and compiled them. The stubs also have been created properly.
When I run the application outside the Eclipse editor, everything works just fine! However, when I want to integrate the files into a bigger project in Eclipse... and starts running it, he tells me he can't find the stub class or something like that. I need to place this one in the classpath but I don't know how to do that in Eclipse? Could anyone help me with this problem?
Thanks!
This is the fault message I get:

D-me

Do you have an idea of what the answer to our
question could be?I don't have much idea about the question myself. I was groping in the dark. :-)
Anyway, the project classpath settings and the external jars (or dependent projects) are a few things which could be experimented with. I'm afraid I couldn't be much help without having a look at what you are trying to do. :-(

Does ATS load testing support Java RMI and T3 protocol?

Hi Experts,
Does ATS load testing support Java RMI and T3 protocol or EJB(J2EE)?
Thanks!

Joseph,
Oracle Application Testing Suite is mainly used for testing of applications from a end user perspective and offers an intuitive capture/replay for web, Siebel, EBS, JDE, Fusion apps or SOA based application through WebServices WSDL imports.
The scripting environment (Oracle OpenScript) does not support script creation by recording JAVA RBI or T3 protocol as we lack a recorder for it, but the scrips are created as pure JAVA code so you could use the JAVA language to write a small RMI cor T3 client for your testing.
We have customers that have used Application Testing Suite to test non-UI based testing, like: JMS, FTP, Tuxedo and others, but it require a bit of coding.
Please let me know if you would like to know more or discuss your options

Standard Java RMI and WLS5.1?

I would surmise that the problem you are seeing is the result of the fact
that we do not except standard Java RMI calls using the functionality in the
JDK. You must use the WebLogic implementation of RMI. It is exactly the
same in terms of APIs, but we have gone through and optimize the underlying
protocol.
Please see the documentation for more details.
We offer both RMI over IIOP and RMI over T3.

Hello,
I was trying to get a simple callback demo working using standard java
RMI and the WLS5.1. Unfortunately, although things seemed to compile
and launch smoothly, when the client started up and tried to talk to the
WLS I would get the following error:
weblogic.rmi.server.ExportException: A description for CallbackImpl was
found but it could not be read due to: [Failed to find a stub for [class
CallbackImpl] implements at least one interface [interface Callback]
which extends Remote.]
weblogic.rmi.StubNotFoundException: Failed to find a stub for [class
CallbackImpl] implements at least one interface [interface Callback]
which extends Remote.
I tried determining if this was a classpath problem, but all my efforts
kept producing this result.
On the flip side, if I retool my objects slightly in order to make them
use weblogic.rmi.*, then everything works perfectly.
Is there a tradeoff to using weblogic.rmi over java.rmi?
Also, does anyone have any ideas as to what might be causing my error
when using standard rmi?
Thanks so much in advance,

Java RMI and P2P

Hello everybody...
I'm planing a school project regarding Peer-to-Peer networking using Java RMI technology. The general idea is to use a Java Applets (using a special security manager) which acts as a P2P client and uses RMI to communicate with other Clients. I think security would be no problem if I use signed Applets...
With this foundation I will be able to programm a chat or a multiplayer chess or whatever.
Do you think this concept is possible and realistic or are there any better solutions?
Thank you for your advice.
Best regards

Rmi cobol and java

Friends is it possible to have interaction between java and Cobol.
I mean I want to use JSP as front end and the entered data(by some user) should be passed as parameter to a COBOL program.Then the data is processed and the o/p from COBOL program should be passed to JSP .
thanks.

Easy - as long as you can find a remote object protocol that is supported by java AND cobol. CORBA should do the trick - is there are cobol CORBA? I doubt cobol supports java rmi - though it may support IIOP, which would also be effective.

Java.rmi.ServerException: Server unavailable, please try later

I'm testing a service proxy in JDeveloper 10.1.3.1.

Is this a failure of the RMI server on my side or is it a failure to connect to the service? Is the destination service sending this to me or just the transmission code?
It looks to me from the trace and the vagueness of the message that this is from the Oracle transmission code in the StreamingSender class, not a message received from the destination webservice. Would love some confirmation, though.
Thanks for any help.

RMI Trouble - UnmarshalException

I had several classes thata had been working great under RMI until I made a smalla change
I change the package path of my classes adding a parent package and adding a level in the
directory path (from D:\Des\MicroApl to D:\Des\MicroAplsrc), so my directory tree change from:
D:\Des\MicroApl
transmision
modelo
controlador
vista
to:
D:\Des\MicroApl
jars
make
classes
docs
src
rut
transmision
modelo
controlador
vista
So I change the package statement in the classes adding the new level, for instance, from:
package modelo;
to:
package rut.modelo;
and i change my make files in order to compile the classes acordingly, from:
javac modelo\ModeloMaestro.java
to:
javac rut\modelo\ModeloMaestro.java
and from:
rmic modelo.ModeloMaestro
to:
rmic rut.modelo.ModeloMaestro
I also changed the path of my call from:
java -cp .\mimjdbc-2_2.jar;. modelo.ModeloMaestro
to:
java -cp D:\Des\MicroApl\jars\mimjdbc-2_2.jar;. rut.modelo.ModeloMaestro
Now, after compiling without any error, I get a big runtime error, as follows:
Excepcion Remota de servidor: RemoteException occurred in server thread; nested exception is:
     java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
     java.lang.ClassNotFoundException: rut.modelo.ModeloMaestro_Stub

InitialContext and javax.rmi.PortableRemoteObject

I've been trying to locate a very annoying problem that I get when I try to bind remote objects in JNDI. I have now located the problem but I have no idea why this causes a problem or how to fix it. It seems that creating an InitialContext has different effects depending whether I create an instance of javax.rmi.PortableRemoteObject before.
Here's what I am doing...
1:Context ctx = new InitialContext(); //Create Initial context
2://Instantiate remote object (extends PortableRemoteObject and stubs gen with rmic with -iiop flag)
3:Hello hello = new HelloImpl();
4:ctx.rebind("hello", hello); //Bind to JNDI
5:System.out.println("Object bound!!!!!");
This code works fine. The problem occurs when I try to instantiate the remote object before creating the InitialContext for the first time (I.e. I move line 3 to the top) I then get the following exception:

I assume the problem is in the javax.rmi.PortableRemoteObject's (HelloImpl's) constructor since that is the only code that's beeing executed. But how could that effect the instantiation of the InitialContext? I should also say that it seems that it is only the first time that an InitialContext is created that is critical. If I create on instance of it before instantiating the first PortableRemoteObject, all subsequently created instances of InitialContext succeed in binding remote (RMI-IIOP) objects.
Can someone help me understand why this happens and how to avoid it? I don't want to have to create an InitialContext the first thing I do in the code. It seems the PortableRemoteObject constructor somehow changes the configuration in a way that makes the bindings fail... How? Why? Can I prevent it from happening?
Any input appreciated!

my bean is running in my EJBServer, and I have it in the classpath of the RmiRegistry (which runs as part of my server). The RmiRegistry is an actual ".bat" file that starts an RMI Registry (I assume).
The client is not a bean and is run like this:
java com.titan.cabin.Client_1
All it does is create a cabin and then read it back. It works, it not only gets the context, but also creates, persists and reads that cabin bean.
Is it because java automatically finds all RmiRegistries running on the computer? This makes sense, but I read on java.sun.com that you need a stub class for your clients. And if it is true, then how does it get the context and remote/home interface of a bean on another server?
