SocketRequestResponseServer.java - Socket Server Testing Program

This section provides a tutorial example on how to write a socket level server side testing program to receive and record request received from a client program.

In order to learn how input parameters are encoded in the SOAP Body element when executing the test program described in the previous tutorial, I need to capture the HTTP request generated by Axis2.

So I need a socket server test program to verify how my client program is doing by recording whatever received from the client. This is very important because there is no 'trace" function on the client side to see what client is sending.

Here is my socket server test program, SocketRequestResponseServer.java:

/* SocketRequestResponseServer.java

import java.io.*;
import java.net.*;
public class SocketRequestResponseServer {
   public static void main(String[] args) {
      PrintStream out = System.out;

// Checking command line arguments
      if (args.length < 2) {
         out.println("Usage:");
         out.println(
            "java SocketRequestResponseServer inFile outFile");
         return;
      }
      String inFile = args[0];
      String outFile = args[1];

      try {
// Reading the response from a file
         File objFile = new File(inFile);
         int resLen = (int) objFile.length();
         byte[] resBytes = new byte[resLen];
         FileInputStream inStream = new FileInputStream(objFile);
         inStream.read(resBytes);
         inStream.close();

// Creating socket socket
         ServerSocket server = new ServerSocket(8888);
         out.println("Listening at 8888");
         Socket con = server.accept();
         out.println("Connection received from "
            +con.getInetAddress().toString());

// Receiving the request
         InputStream reqStream = con.getInputStream();
         byte[] reqBytes = new byte[10240];
         int reqLen = reqStream.read(reqBytes);

// Sending the response
         OutputStream resStream = con.getOutputStream();
         resStream.write(resBytes);

         reqStream.close();
         resStream.close();

// Writing the request to a file 
         FileOutputStream outStream = new FileOutputStream(outFile);
         outStream.write(reqBytes,0,reqLen);
         outStream.close();

// Output counts
         out.println("Request length: "+reqLen);
         out.println("Response length: "+resLen);
      } catch (Exception e) {
         e.printStackTrace();
      }
   }
}
