Hello,
I want to export a Repository with RMI. So I gathered bot
jackrabbit-core and jackrabbit-jcr-rmi stuff and (of course) have some
problems. Could you please point me to the right direction?
When I run the sample code it throws the following exception:
Exception in thread "main" java.rmi.server.ExportException: object
already exported
at sun.rmi.transport.ObjectTable.putTarget(ObjectTable.java:172)
at sun.rmi.transport.Transport.exportObject(Transport.java:75)

sun.rmi.transport.tcp.TCPTransport.exportObject(TCPTransport.java:190)

at
java.rmi.server.UnicastRemoteObject.exportObject(UnicastRemoteObject.java:235)
at jackrabbit.rmiserver.Server.main(Server.java:27)
My server code:
public class Server {
public static void main(String[] args) throws Exception {
Repository repository = getRepository();
RemoteRepository remoteRepository = getRemoteRepository(repository);
RemoteRepository stub =
(RemoteRepository)UnicastRemoteObject.exportObject(remoteRepository, 0);
Registry registry = LocateRegistry.getRegistry();
registry.bind("rmi_repo", stub);
System.out.println("Server ready");
}
private static RemoteRepository getRemoteRepository(Repository
repository) throws RemoteException {
RemoteAdapterFactory factory = new ServerAdapterFactory();
RemoteRepository remote = factory.getRemoteRepository(repository);
return remote;
}
private static Repository getRepository() throws NamingException,
RepositoryException {
String configFile = "repotest/repository.xml";
String repHomeDir = "repotest";
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.jackrabbit.core.jndi.provider.DummyInitialContextFactory");
env.put(Context.PROVIDER_URL, "localhost");
InitialContext ctx = new InitialContext(env);
RegistryHelper.registerRepository(ctx,
"repo",
configFile,
repHomeDir,
true);
Repository r = (Repository)ctx.lookup("repo");
return r;
}
}
