Hello Vijay,
I think this is your code:
import com.sap.aii.mapping.api.StreamTransformation;
import com.sap.aii.mapping.api.AbstractTrace;
import com.sap.aii.mapping.api.StreamTransformationConstants;
import java.util.Map;
import java.io.*;
public class PayloadToXMLField1 implements StreamTransformation {
    String strXML = new String();
   //Declare the XML tag for your XML message
   String StartXMLTag = "<DocumentBody>";
   String EndXMLTag = "</DocumentBody>";
   //String StartXMLTag1 = "<Code>";
   //String EndXMLTag1 = "</Code>";
    AbstractTrace trace;
    private Map param = null;
    public void setParameter(Map param) {
        this.param = param;
    public void execute(InputStream in, OutputStream out) {
        trace =
            (AbstractTrace) param.get(
                StreamTransformationConstants.MAPPING_TRACE);
        trace.addInfo("Process Started");
        try {
            StringBuffer strbuffer = new StringBuffer();
            byte[] b = new byte[4096];
            for (int n;(n = in.read(b)) != -1;) {
                strbuffer.append(new String(b, 0, n));
            strXML = strbuffer.toString();
        } catch (Exception e) {
            System.out.println("Exception Occurred");
        String outputPayload =
            StartXMLTag
         + "<![CDATA["
         + strXML
         + "]]>"
         + EndXMLTag;
        try {
            out.write(outputPayload.getBytes());
         trace.addInfo("Process Completed");;
        } catch (Exception e) {
            trace.addInfo("Process Terminated: Error in writing out payload");;
I need this code to be converted in UDF if Java map cannot be called in Message Map.
Can anyone help me how to write UDF for the same java map.
Thanks and Regards
