Attached is the code in Java Mapping
        private InputStream  payload ;
     /* (non-Javadoc)
@see com.sap.aii.mapping.api.StreamTransformation#setParameter(java.util.Map)
     public void setParameter(Map arg0) {
          this.param = arg0;
       if (param == null) {
           this.param = new HashMap();
     /* (non-Javadoc)
@see com.sap.aii.mapping.api.StreamTransformation#execute(java.io.InputStream, java.io.OutputStream)
     public void execute(InputStream arg0, OutputStream arg1)
          throws StreamTransformationException {
               DefaultHandler handler = this;
               try {
                 payload = arg0;
             BufferedReader inp = new BufferedReader(new InputStreamReader(payload));
       StringBuffer buffer = new StringBuffer();
       String line="";
     while ((line = inp.readLine()) != null) {
                    buffer.append(line);
                      source=buffer.toString();
  if(source != null)
  param.put("key1",source);
  else
  param.put("key1","Its Empty");
               catch (Exception e){
                    e.printStackTrace();
