Hi I'm trying to run a java application that binds a class to the naming server, but i constantly get a ClassNotFoundException
First I start the registry:
rmiregistry
then from eclipse I try to execute the server but get this error
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.lang.ClassNotFoundException: progInternet2008.commons.NominabileFactory at sun.rmi.server.UnicastServerRef.oldDispatch(UnicastServerRef.java:396) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:250) at sun.rmi.transport.Transport$1.run(Transport.java:159) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:155) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:535) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:790) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:649) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:255) at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:233) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:359) at sun.rmi.registry.RegistryImpl_Stub.rebind(Unknown Source) at progInternet2008.Pozzobon.tesi.Slave.main(Slave.java:54) Caused by: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.lang.ClassNotFoundException: progInternet2008.commons.NominabileFactory at sun.rmi.registry.RegistryImpl_Skel.dispatch(Unknown Source) at sun.rmi.server.UnicastServerRef.oldDispatch(UnicastServerRef.java:386) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:250) at sun.rmi.transport.Transport$1.run(Transport.java:159) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:155) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:535) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:790) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:649) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.ClassNotFoundException: progInternet2008.commons.NominabileFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:247) at sun.rmi.server.LoaderHandler.loadProxyInterfaces(LoaderHandler.java:711) at sun.rmi.server.LoaderHandler.loadProxyClass(LoaderHandler.java:655) at sun.rmi.server.LoaderHandler.loadProxyClass(LoaderHandler.java:592) at java.rmi.server.RMIClassLoader$2.loadProxyClass(RMIClassLoader.java:628) at java.rmi.server.RMIClassLoader.loadProxyClass(RMIClassLoader.java:294) at sun.rmi.server.MarshalInputStream.resolveProxyClass(MarshalInputStream.java:238) at java.io.ObjectInputStream.readProxyDesc(ObjectInputStream.java:1531) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1493) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1732) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) ... 12 more
I've read the RMI Java tutorial but still could not get it working...
As VM Arguments I've set this:
-Djava.rmi.server.codebase=file:${workspace_loc}/progInternet2008
please help me
(I'm using Java 6)
Run the rmiregisrty
command from your /bin, /build, or /build/classes folder, whichever folder is the root of your built files.
I spent half a day trying to solve that same thing.
