java.rmi.UnmarshalException: unrecognized method hash: method not supported by remote object

I have two web application, the first one RMIServer contains the following

public interface EasyPDFGeneratorRemoteInterface extends Remote {

public File generatePDFAmin(File sourceFile) throws RemoteException ;
}

public class EasyPDFGenerator extends UnicastRemoteObject 
    implements EasyPDFGeneratorRemoteInterface {


    public File generatePDFAmin(File sourceFile)  {
//implementation details....
}

then an object of type EasyPDFGenerator is registered in the registry.

And the Second contains 

public interface EasyPDFGeneratorRemoteInterface extends Remote {

public File generatePDFAmin(File sourceFile) throws RemoteException ;
}

class test {

private File generatePDF(File file) {

    File pdfFile = null;
    try {

        EasyPDFGeneratorRemoteInterface easyPDFGenerator = getRemoteEasyPDFGenerator();// get the remote object.
        easyPDFGenerator.getClass.getMethods();// the array contains the method generatePDFAmin.
        pdfFile = easyPDFGenerator.generatePDFAmin(file);// throws the exception.

    } catch (RemoteException ex) {

    }

}
}

I am not sure what could be causing the problem since am getting the remote object ,and it does contain the method that the UnmarshalException is thrown when it gets invoked.

You changed your remote interface definition without reploying all the .class files affected. If you're using a generated stub, you didn't regenerate that either.
