Hi,
I created this Java network server:
import java.net.*;
import java.io.*;
public class EchoServer
{
ServerSocket m_ServerSocket;
public EchoServer()
{
try
{
// Create the server socket.
m_ServerSocket = new ServerSocket(12111);
}
catch(IOException ioe)
{
System.out.println("Could not create server socket at 12111. Quitting.");
System.exit(-1);
}
System.out.println("Listening for clients on 12111...");
// Successfully created Server Socket. Now wait for connections.
int id = 0;
while(true)
{
try
{
// Accept incoming connections.
Socket clientSocket = m_ServerSocket.accept();
ClientServiceThread cliThread = new ClientServiceThread(clientSocket, id++);
cliThread.start();
}
catch(IOException ioe)
{
System.out.println("Exception encountered on accept. Ignoring. Stack Trace
:");
ioe.printStackTrace();
}
}
}
public static void main (String[] args)
{
new EchoServer();
}
class ClientServiceThread extends Thread
{
Socket m_clientSocket;
int m_clientID = -1;
boolean m_bRunThread = true;
ClientServiceThread(Socket s, int clientID)
{
m_clientSocket = s;
m_clientID = clientID;
}
public void run()
{
// Obtain the input stream and the output stream for the socket
// A good practice is to encapsulate them with a BufferedReader
// and a PrintWriter as shown below.
BufferedReader in = null;
PrintWriter out = null;
// Print out details of this connection
System.out.println("Accepted Client : ID - " + m_clientID + " : Address - "
+
m_clientSocket.getInetAddress().getHostName());
try
{
in = new BufferedReader(new
InputStreamReader(m_clientSocket.getInputStream()));
out = new PrintWriter(new
OutputStreamWriter(m_clientSocket.getOutputStream()));
// At this point, we can read for input and reply with appropriate output.
// Run in a loop until m_bRunThread is set to false
while(m_bRunThread)
{
// read incoming stream
String clientCommand = in.readLine();
System.out.println("Client Says :" + clientCommand);
if(clientCommand.equalsIgnoreCase("quit"))
{
// Special command. Quit this thread
m_bRunThread = false;
System.out.print("Stopping client thread for client : " + m_clientID);
}
else
{
// Echo it back to the client.
out.println(clientCommand);
out.flush();
}
}
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
// Clean up
try
{
in.close();
out.close();
m_clientSocket.close();
System.out.println("...Stopped");
}
catch(IOException ioe)
{
ioe.printStackTrace();
}
}
}
}
}
I want to insert this code into OSGI bundle. At the moment I don't have
configured Glassfish with datasource to test the bundle. What I have to do
in order to configure the Java server to listen for incomming connections
when I deploy it on Glassfish server?
Do I need to add somenthing into the OSGI bundle activator to make the Java
server listen for incomming connections?
Best Wishes
