I am developing a simple program in JXTA 2.7 and it is showing me the following error.

public static void main(String[] args) throws IOException, PeerGroupException {
        System.setProperty(Logging.JXTA_LOGGING_PROPERTY, Level.OFF.toString());
        NetworkManager manager = new NetworkManager(NetworkManager.ConfigMode.EDGE, "Test");
        System.out.println(" S t a r t ing JXTA");
        manager.startNetwork();
        System.out.println(" JXTA St a r t ed ");            
}

Error:

I am not able to figure out what is going wrong here. I have downloaded the missing libraries jetty and has given it into the library path(netbeans 7.0.1). Anyone please help me out.

  • Actually i downloaded the netty from the given website and included it in library. Even i also put them in ext/lib folder of my jdk. But still it is showing me the same error. – ATR Mar 01 '12 at 19:51

    OK, well add a comment after Norman's answer - otherwise he won't be pinged that you've commented. – halfer Mar 01 '12 at 19:54

You need to include netty into your classpath. You can get it from netty.io website.

  • I have done as you said but still it is not working. i have included the jar file in libraries(netbeans). – ATR Mar 01 '12 at 20:27
  • What version of Netty are you using? See [here](http://stackoverflow.com/questions/9482029/jxta-practical-jxta-ii-examples-exception-when-netmanager-startnetwork-is/9485309#9485309) – halfer Mar 01 '12 at 22:16
  • I am the one who released JXTA 2.6 and 2.7. And yes, you need to have the proper version of Netty in your class path. We delivered a temporary one in the jar dependencies, because the code was not already included in Netty's final release. But things should be cleared by now. – Jérôme Verstrynge Mar 11 '12 at 00:16
  • @JVerstry : That problem got solved. I want to send a message from one peer to another peer. I am not getting any simple exact example for that. From many days i am reading just documents of JXTA. Can you give any link to such a simple example where one peer in network sends a simple hello message to another peer in the same network using jxta 2.7/2.6 ? – ATR Mar 12 '12 at 15:03
