Is it possible to take control over ssl handshake process?

Question

Hi,
I'd like to write an application that will show whole ssl handshake process step by step. So I was wondering if it is possible to do something like that:
when user connects his ssl client to ssl server he can push eg."Next" button moving to the next handshake step. But to do that i must have control on that handshake process:).
Thanx.

Yeah I forgot about read and write. Forgive me please my questions, but I am just beginning programmer. Anyway I still get this exception: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
Ofcourse I screwed something again, can you tell me what?
Here is client part:
while(myAppData.hasRemaining()){
     SSLEngineResult result = engine.wrap(myAppData, myNetData);
//     System.out.println(result.getStatus()); //here i get BUFFER_OVERFLOW why?
     if(result.getStatus() == SSLEngineResult.Status.OK){
     myAppData.compact();
     while(myNetData.hasRemaining()){
     int num = socketChannel.write(myNetData);
                              System.out.println(num);
     if(num == -1){
          System.out.println("close channel");
     }else if(num == 0){
          System.out.println("no write");
     System.out.println(result.getStatus());
     int bytesConsumed = result.bytesConsumed();
     System.out.println("Bytes consumed: "+bytesConsumed);
     int bytesProduced = result.bytesProduced();
     System.out.println("Bytes produced: "+bytesProduced);
     handStatus = result.getHandshakeStatus();
     System.out.println(handStatus);     //NEED-UNWRAP
     }else if(result.getStatus() == SSLEngineResult.Status.BUFFER_OVERFLOW){
//          System.out.println(result.getStatus());
     }else if(result.getStatus() == SSLEngineResult.Status.BUFFER_UNDERFLOW){
//          System.out.println(result.getStatus());                    }                                   
and server part:
int num = sc.read(peerNetData);
     System.out.println(num);
     if(num == -1){
          //closed channel
          System.out.println("num=-1");
     }else if(num == 0){
          //no bytes read
          System.out.println("num=0");
     }else{
          peerNetData.flip();
//here I get this exception
          result = engine.unwrap(peerNetData, peerAppData);
          if(result.getStatus() == SSLEngineResult.Status.OK){
               peerNetData.compact();
          int bytesConsumed = result.bytesConsumed();
          int bytesProduced = result.bytesProduced();
          hStat = result.getHandshakeStatus();
                         SSLEngineResult.Status status = result.getStatus();
     System.out.println(status);
     System.out.println(hStat);
     if(peerAppData.hasRemaining()){
          //use peerAppData               
}
