Unseen exception (RMI)

I am using RMI to create a client server hotel booking system applet.
My client sends the server a new booking by calling the addBooking() method that the server provides. iI get the following error when I try to send it to the server that I don't understand.
MalformedURLException
java.rmi.MarshalException: error marshalling arguments; nested exception is:
java.io.NotSerializableException: BookingCan anyone help?

It didn't but I added the "implements seriailizable" bit and now get this exception.

How do you make the client stub class available to the Server? Is it present in Server JVM's classpath or are you relying upon the dynamic class loading of the stub class from the client to the server?
If you're using dynamic class loading (and from your description it seems so) then make sure that the java.rmi.server.codebase property has been set appropriately in the client side so that the server can get the Stub class definition of the client when you register the client as a remote object to the server. From the stack trace it looks like the server can't unmarshall the remote reference passed by the client because of a malformed URL while trying to get the client Stub class.
Try this first. Keep the client stub (generated by rmic) in the server's classpath and code just the way you're doing now. I think the problem will then disappear.
Of course that may not be a desirable solution (especially if your client is an applet). In that case you'll have to figure out ways of making the client stub available to the server JVM. You may end up writing your own custom RMIClassLoader or explicitly use RMIClassLoader.loadClass() method.

Exception when using RMI in tomcat 5.5, after reloading webapp

When I freshly start tomcat and deploy my web app, I can use RMI by creating a local registry and binding my objects.
However, as soon as I reload the web application, RMI no longer works and gives me this exception:

Hi all!
I get the same Exception using Tomcat 5.5. When registering an object outside tomcat lookup works fine. Only when registering an object inside a webapp!
Would be great if anyone got a tip to solve it!

RMI ClassNotFoundException:HelloImpl_stub

Hi there,
I'm trying to start my Rmi Server but I always get this exception:
RMI ClassNotFoundException:HelloImpl_Stub
In the rmiregistry window the following message appears:
File not found when looking for: HelloImpl_stub
All my class files are in the dir c:\mysrc, and I started rmiregistry there, with no classpath setted. The classes aren't inside packages.
Then, I used the following command line, with the CLASSPATH including c:\mysrc :
java -Djava.rmi.server.codebase=file:c:\mysrc -Djava.rmi.server.hostname=computer07 HelloImpl
When I do that I get those messages showed above.
I'm using Windows NT Workstation and I'm not using a Web Server.
I would aprecciate any help.
Thanks,
Nei

Change of ip in wireless networks - urgent!

hi everyone!
i am developing an application using rmi in a wlan network and face the following problem:
my application is distributed among a notebook and a pda, uses rmi for all transfer and method invokation and works fine after setup.
but when my pda changes its ip address (dhcp), problems come up.
i do rebind and export correctly, but still receive a java.rmi.ConnectException because rmi still tries to send the objects to the old ip address, which is not valid any more.
does rmi cache this ip somewhere? how can i work around this problem?
what do i have to do to make rmi recognize the new ip?
any cure???
thanks for help!!
kirk

hi ejp!
thanks for reply, but i do exactly want you tell me to do:
program works like this:
export object
rebind
lookup
change of ip new object
export
rebind
lookup stub
i cannot unexport the old object, since i have to use personal java on the pda, so i create a new object and still receive a connect exception.
rmi cannot make a connection to old ip address and is not recognizing that my device changed its location.
still any ideas?
thx a lot!

Tutorial problems

Hi!
I'm trying to learn how to use RMI, but I'm stuck even with tutorial. I just can't compile that simple HTTP server, I get error:
ClassFileServer.java:22:cannot find symbol
symbol: class ClassServer
public class ClassFileServer extends ClassServer {
I'm sure it's something simple, I just never worked with this suff.
Thanks!

I followed everything in the tutorial as written. But to be honest, either I'm doing something really wrong, or there is problem with this tutorial, because even before I tried to run that server, I noticed warnings in interface Compute and class ComputePi, which I think shouldn't be there, since it's copy-paste tutorial...
Never mind, I found another one [http://java.sun.com/developer/onlineTraining/rmi/exercises/BootstrapExample/index.html] and started HTTP server successfuly. But when I tried to start RMIServer, I got exception
"RMI TCP Connection(idle)" java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:3285 accept,resolve)
Is it problem with the port? I'm not sure what to set there, when I'm trying to do it on localhost.

Client can't access Serializable classes on Server

Hi there, i have created a very simple client server model and had it running fine. I then added a new serializable class to the server and return it in a new method. Now when i try to run that method on the client side it complains it cannot find my new serializable class ("no class def found exception: rmi/server/ServerObject.class"). This is how it's setup at the moment:
Server
-ServerFront extends Remote
-Server implements ServerFront
-ServerObject implements Serializable
The server binds itself to the registry as such:
ServerFront engine = new Server();
String name = "Server";
ServerFront stub = (ServerFront)UnicastRemoteObject.exportObject(engine, 0);
Registry registry = LocateRegistry.getRegistry();
registry.rebind(name, stub);The ServerObject class looks like this:
public class ServerObject implements Serializable
    private static final long serialVersionUID = 10L;
    //methods
}The ServerFront interface has a method as such:
ServerObject getServerObject () throws RemoteException;    Client
-Client
The client gets a reference to the server as follows:
String name = "Server";
Registry registry = LocateRegistry.getRegistry("127.0.0.1");
server = (ServerFront)registry.lookup(name);Then tries to run the getServerObject() method:
ServerObject = server.getServerObject();I run the client and server from jar files using the following commands:
start java -Djava.rmi.server.codebase="http://www.xenwars.com/Server.jar" -Djava.security.policy=security.policy -jar Server.jar
java -Djava.security.policy=security.policy -jar Client.jar"security.policy" allows all access, and the codebase URL points to my webserver where i uploaded an identical copy of the Server jar file that i'm trying to run.
So... i've read all the Sun documentation and such and i'm massively confused why my client isn't simply downloading the serializable class as it's supposed to. Any help is massively appreciated, thanks :D

By a mirrored interface i mean i just created an interface based off my existing serializable classes, i.e. copied the method constructors into an interface class and made the serializable class implement that interface.
I think that must have been the problem then, that i wasn't giving the client an interface to the serializable classes on the server that it was attempting to download. I thought by using RMI on a serializable class it would just download that class when it needs it and so wouldn't need an interface pre-defining it.
Thanks for the help! I'm now working on a system with 3 servers and one client, where two servers have various methods implemented and the third one acts as a bridge between the other two servers and the client - so the client only has to deal with one server. It's working fine but it's pretty annoying having to mirror all the methods from both servers' interface classes in the server that acts as a bridge's interface class - is there any way that the bridge server can inherit the other two servers interfaces into its own so i don't need to make loads of duplicate "shell" methods like this:
// second server
public ArrayList<Thing> getAllThings ()
    return things;
// bridge server
private SecondServerFront secondServer; // reference loaded in constructor
public ArrayList<Thing> getAllThings () throws RemoteException
    return secondServer.getAllThings();
}

OS Signal Handling problem

Hi, I have a problem trying to handle operating system signals. The exception I get is: Exception already handled by de JVM.
The enviroment that runs my application is:
-IBM AIX 4.3
-IBM JRE 1.3.0
The process is launched with "nohup"
The complete line is: nohup java -jar -Dlog4j.configuration=log.xml etec.jar >/dev/null 2>/dev/null &The code is:
try
if (senyalInterrupcion != null)
    Signal.handle(new Signal (signalName), new SignalHandler ()
      public void handle(Signal arg0)
        System.exit(0);
catch (IllegalArgumentException ex)
ex.printStackTrace ();
}I know that the use of com.sun.* classes is not recommended by Sun, but I need to communicate the JVM in wich my application run with the shell, if anyone knows a better method (except RMI) please let me know.
P.S. Sorry for my english
Thanks in advance,
Juanjo

As of jdk1.3, run w/ Java -Xrs option (i.e., java -Xrs myProg) so default JVM signal handlers are not run. Then, you can install your own signal handlers using sun.misc.Signal and SignalHandler and they will not conflict with the JVM's handlers. See the following article for excellent coverage of the topic:

Rmi-iiop: calling secured method on Ejb -- NO PERMISSION Exception

In WL6.1, I have an Ejb with secured methods. The (Swing) client application accesses the Ejb through rmi-iiop using the JDK1.3.1 Orb.
Unfortunately, it seems that the caller identity (which was supplied in the InitialContext lookup) is not propagated
to the server: any call to a secured method
fails with a CORBA NO_PERMISSION Exception.
Using the t3 protocol the program works fine, but that would require the 25Mb weblogic.jar on all clients, which is unattainable for us.
Any ideas how this situation can be corrected?

Hi Allard,
Please pose this in the weblogic.developer.interest.rmi-iiop.

Java.rmi.RemoteException: EJB Exception: while calling an EJB method,

Hi
I am getting below error while calling a stateless EJB method. There is some validation checks while performing ejb's modify() method and a RuntimeException is thrown in case of validation failure.The modify() method internally calls other stateless ejb as well.
The problem I'm facing is, instead of getting the expected RuntimeException in the Servlet, i am getting RemoteException. I am using WLS 9 MP1, all participating ejbs are stateless and i am using default transaction attributes(Supports) for these ejbs.
The interesting part is, at the ejb layer RuntimeException is thrown as expected, but this exception changed to RemoteException at the servlet's end where i am catching the ejb call exceptions.
I am new to WLS, please suggest/help me out of this exception.
Any help is truly appreciated.

Hi,
If i don't misunderstand, you are using the RuntimeException as an application exception, right?
Have you annotated it or denoted it in deployment descriptor?

This exception means that xml namespaces are different.
Etc. soap has xml element which doesn't belong to namespace of parent xml element and namespace is set without prefix.
I had such problem.
Try to set namespace prefix for this element.
Example:
<el1>
<el2 xmlns="http://..."/>
</el1>
Should be
<el1>
<q:el2 xmlns:q="http://..."/>
</el1>

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.

Connection to CRX via RMI and getting WeakReference value..... with an exception!

Hi there,
I have the following problem.
I opened a ticket in Day Care Support system, about CRX users/group membership that got lost while synchronization with our LDAP server.
Although when the user and the group had been created (and therefore taken from that same LDAP server), the membership was good.... but after some time the membership got lost......
So what i am trying to do now is a Java program that connects to CRX via RMI.
And gets the list of all the users from a group (aka membership).
The idea is to monitor the membership each seconds.
But when trying to get the property "rep:members" of the group, I have the following exception :
javax.jcr.ValueFormatException: Unknown value type 10
          at org.apache.jackrabbit.rmi.server.ServerObject.getRepositoryException(ServerObject.java:13 9)

          at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:322)"
I searched a little bit and found that "10" is the number for type WeakReference.
That's normal to me because memberships are stored in the group as a list reference to users linked to that group....
Anyways, what's not normal to me is that when the type is "10" the API does not let me get the Value (cf. ServerProperty.getValues() method)
