ServletInputStream in Servlet Forwarding empty

Question

Please help me, i think i have a problem.
After reading and checking "request"
seem that the xml message soap included in "request" disappear.
I have to forwarding it to another servlet.
Is too late? I have lost it?
Where is it ?
I use the RequestDispatcher.forward() method for forwarding
but (i'm sure) the second servlet receives the "request.getInputStream()" empty.
Who can help me?
Thanks in advance
my code :
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ServletInputStream in = request.getInputStream();
byte[] fre=null;
String xml="";     
while (in.available()>0) {
try {
fre = new byte[in.available()];
in.read(fre);
xml = xml + new String(fre);
} catch (Exception exc) {
exc.printStackTrace();
if (ckeck(xml)) {     
request.getRequestDispatcher("myservlet2").forward(request,response);
}

You have already read the input stream. Once read, and it gets read, it can not be re-read. If you want the information in both places, read it in the first servlet and store it in a scope that the other servlet can read (like as a request attribute:
  byte[] fre=null;
  String xml="";
  while (in.available()>0) {
    try {
      fre = new byte[in.available()];
      in.read(fre);
      xml = xml + new String(fre);
    } catch (Exception exc) {
      exc.printStackTrace();
  request.setAttribute("xml", xml);
  if (ckeck(xml)) {
    request.getRequestDispatcher("myservlet2").forward(request,response);
//... then in myservlet2
  String xml = (String)request.getAttribute("xml");
