Add XML header?

Question

Hi Experts ,
I need to add this extra 2nd line in my generated xml output of graphical mapping.
<?xml version="1.0" encoding="UTF-8"?>
<?Siebel-Property-Set EscapeNames="false"?>
Is there any smart way to add this 2nd line? I have already created a graphical mapping for the message with complex lookups and do not wish change it much.
Thanks
Shamly.

Hi Shamly,
You are on right path.
Use your graphical mapping (for complex lookup and other logic) after that use another Java Mapping ( to add <?  ?> line) in Operational Mapping.
Use this bolg to develop Java Mapping /people/carlosivan.prietorubio/blog/2007/12/21/implementing-a-java-mapping-in-sap-pi
Hope this code will help you
import java.io.*;
import java.util.*;
import com.sap.aii.mapping.api.*;
public class DynamicMapping implements StreamTransformation {
    private Map param;
    public void setParameter(Map param) {
        this.param = param;
    public void execute(InputStream in, OutputStream out) throws StreamTransformationException {
        try {
          byte[] b = new byte [in. available ()]; //  in.available() is in square brackets
                        in.read(b);
          StringBuffer input = new StringBuffer( new String(b));
                        /*note         "   '  '   "       in double Quotes  we can have single Quotes.
                        /Here we are inserting <?Siebel-Property-Set EscapeNames='false'?>  after <?xml version="1.0" encoding="UTF-8"?> i.e after ?> */
          input.insert(input.indexOf("?>")+2, "<?Siebel-Property-Set EscapeNames='false'?>");
                       out.write(b.toString().getBytes()); 
        } catch (IOException ex) {
           ex.printStackTrace();
