HTTP RECEIVER Stopping on CALL ADAPTER

Question

Hi All,
I'm having a problem with HTTP Receiver adapter, It's an IDOC that need to send to a HTTP Listener. Everything works until send the XML to the http listener, I have made a single listener in java to verify how this XML is coming from adapter.
I got the follow information:
POST /?msgguid=45ECD392770B0046020000000AA00D4B&service=MYSERVICE&namespace=urn%3amynamespace%3atest%3aintegration&interface=MI_ED_MYIDOC_IB&qos=EO HTTP/1.0
content-type: text/xml
content-length: 1550
connection: close
accept: */*
user-agent: SAP Web Application Server (1.0;640)
host: 10.10.10.10:5556
accept-encoding: gzip
<?xml version="1.0" encoding="UTF-8"?>
It stops on first line of XML <b><?xml version="1.0" encoding="UTF-8"?></b> and stay stoped until I break the connection.
The server is SAP XI 3.0 SP15.

Answer 1

Hi Renjith, yes it's a custom java program and I'm trying to write on the console the stream on the console.
What I need to do is certify if SAP XI is delivering the message to the legacy system. So, I know that all configuration on scenario for integration between this legacy system and SAP R/3 is correct. And I'm almost sure that error is on the legacy system side that I don't have credentials to verify.
Look at the source code below:
import java.io.*;
import java.net.*;
class SocketServer {
   ServerSocket server = null;
   Socket client = null;
   BufferedReader in = null;
   PrintWriter out = null;
   String line;
   SocketServer(){ //Begin Constructor
     this.listenSocket();
   } //End Constructor
  public void listenSocket(){
    try{
      server = new ServerSocket(5556);
    } catch (IOException e) {
      System.out.println("Could not listen on port 5556");
      System.exit(-1);
    try{
      client = server.accept();
    } catch (IOException e) {
      System.out.println("Accept failed: 5556");
      System.exit(-1);
    try{
      in = new BufferedReader(new InputStreamReader(client.getInputStream()));
      out = new PrintWriter(client.getOutputStream(), true);
    } catch (IOException e) {
      System.out.println("Accept failed: 5556");
      System.exit(-1);
    try{
      int i = 0;
      while((line = in.readLine()) != null){
        line = in.readLine();
     System.out.println(i+":"+line);     
        i++;
      //this.finalize();
    } catch (IOException e) {
      System.out.println("Read failed");
      System.exit(-1);
  protected void finalize(){
//Clean up
     try{
        in.close();
        out.close();
        server.close();
    } catch (IOException e) {
        System.out.println("Could not close.");
        System.exit(-1);
  public static void main(String[] args){
        SocketServer frame = new SocketServer();
Thanks,
Daniel
