Vysper/PubSub problem

[Radó András]

Hello,

I created a simple service with vysper and pubsub module.
The demo PubSubClient (from vysper project) connects to it, but after 
connect failed with exception:

(I've tried both trunk and 0.7 versions of demo client)

This is the server snippet:
        XMPPServer server = new XMPPServer("localhost");
        server.addEndpoint(new TCPEndpoint());
        StorageProviderRegistry providerRegistry = new 
MemoryStorageProviderRegistry();
        final AccountManagement accountManagement = (AccountManagement) 
providerRegistry
                .retrieve(AccountManagement.class);

        try {
            if (!accountManagement.verifyAccountExists(EntityImpl
                    .parse("user1@localhost"))) {
accountManagement.addUser(EntityImpl.parse("user1@localhost"), "password1");
            }
            server.setStorageProviderRegistry(providerRegistry);
            server.setTLSCertificateInfo(new 
File("src/main/resources/bogus_mina_tls.cert"), "boguspw");
            server.start();
            server.addModule(new SoftwareVersionModule());
            server.addModule(new EntityTimeModule());
            server.addModule(new XmppPingModule());
            server.addModule(new AdhocCommandsModule());
            server.addModule(new PublishSubscribeModule());

Can anyone help me?

Thanks,
Andras
