not getting response to logon message

USING FIX 5.0

I am trying to send logon message from initiator but not able to see any response in acceptor.

In initiator i setField for logon type(35) and i send message by session.sendToTarget(message);

but i am not getting any response in acceptor side and logon is not successfully done.

*********Acceptor side code**********

---AlertAcceptor.java
class AlertAcceptor

{ Application application = new AlertServer(); //All setting is done socketAcceptor acceptor=socketAcceptor(application ,,,); acceptor.start(); //sleep acceptor.stop(); }

---AlertServer.java

class AlertServer implements Application

{ OnLogon() { //expecting logon from initiator but not getting } OnLogout { }

fromApp() { }

toApp() { }

fromAdmin()
{ }

toAdmin()

{ } }

*********Initiator Side code***************

--AlertInitiator.java

class AlertInitiator

{ Application application = new AlertProcess(); //All setting is done socketInitiator initiator=socketInitiator(application ,,,); initiator.start(); //sleep initiator.stop(); } --AlertProcess.java class AlertProcess implements Application { OnLogon() { Message msg=new Message(); msg.getHeader.setField(new String(35,"A"));//header //additionally two more fields from body session.sendTotarget(msg); } OnLogout() { } fromApp() { } and so on.. }
