Finally my freepastry nodes are working

In past few weeks I have been working with Freepastry in order to implement a p2p substrate. Freepastry is the java implementation of pastry algorithm based on DHT. But I was very unhappy in this case that the Pastry nodes implemented in different machines were not communicating. More technically bootstrap node is not identified by the lately come nodes and hence the nodes are not organizing into a ring. But while running on same JVM it works well. Btw finally I could able to make it worked. i.e nodes are now joining to pastry ring and communicating residing even in different machines also.
Initially It was not working because of that I had forget to implement one code line that perform the call to register() method of endpoint reference object.

Not only that. There are some other points also that I found and which was not mentioned in freepastry tutorial.
1) For the Bootstrap node bootAdress(InetAdrress) should be the real Ip( or the domain name also could be worked but I didn't check ) of the machine and the boot port and bind port should be equal.
e.g
int bindport = Integer.parseInt(args[0]);
InetAdress bootaddr = InetAddress.getByName(args[1]);
int bootport = Integer.parseInt(args[2]);
..............
............
node.boot(bootaddress);

Note that here if you start new node as the bootstrap(parent) node then you should pass local IP or domain name of local maching as as the bootaddr and same port number for both bindport and bootport.
So if the ip of the local machin is 192.168.1.100 then your command line arguments should be like
$java [-options] class 9001 192.168.1.100 9001

2) In FreePastry Application class (in this example MyApp) where we normally initiate the reference for Endpoint, dont forget to call register() method.


import rice.p2p.commonapi.Application;
import rice.p2p.commonapi.Endpoint;
import rice.p2p.commonapi.Id;
import rice.p2p.commonapi.Message;
import rice.p2p.commonapi.Node;
import rice.p2p.commonapi.NodeHandle;
import rice.p2p.commonapi.RouteMessage;


public class MyApp implements Application {

protected Endpoint endpoint;

public MyyApp(Node node) {

this.endpoint = node.buildEndpoint(this, "myinstance");

this.endpoint.register();
}

//some codes go here
................
..................
}

Therefore the Warning is...
If somebody wish to implement freepastry and forget to call this register() method your other pastry nodes who are waiting to receive messages from the first node wont receive pastry messages.
