Re: UDF required !! Cannot create target element Values missing in queue context

Hi

The easiest solution will be , write an simple java map for your response mapping.

Please provide your target structure , if you need any help on the java mapping.

Sample code:

Response message from web service

Image may be NSFW.
Clik here to view.

target msg:

Image may be NSFW.
Clik here to view.

java code:

package com.sap;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.transform.Result;

import javax.xml.transform.Source;

import javax.xml.transform.Transformer;

import javax.xml.transform.TransformerFactory;

import javax.xml.transform.dom.DOMSource;

import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

import org.w3c.dom.Node;

import org.w3c.dom.NodeList;

import com.sap.aii.mapping.api.AbstractTransformation;

import com.sap.aii.mapping.api.StreamTransformationException;

import com.sap.aii.mapping.api.TransformationInput;

import com.sap.aii.mapping.api.TransformationOutput;

publicclass populateResponseMessage extends AbstractTransformation {

      publicvoid transform(TransformationInput arg0, TransformationOutput arg1)

                  throws StreamTransformationException {

            try {

                  DocumentBuilderFactory tfactory = DocumentBuilderFactory

                              .newInstance();

                  DocumentBuilder tbuilder = tfactory.newDocumentBuilder();

                  Document doc = tbuilder.parse(arg0.getInputPayload()

                              .getInputStream());

                  Document newdoc = tbuilder.newDocument();

                  Element root = (Element) newdoc.createElementNS(

                              "urn:sap-com:document:sap:rfc:functions",

                              "ns1:ZTEST_FAULT_MESSAGE_DATA.Response");

                  newdoc.appendChild(root);

                  NodeList nlList = doc.getElementsByTagName("ConversionRateResult");

                  if (nlList.getLength() != 0 && nlList != null) {

                        Node data = nlList.item(0);

                        String sourceval = data.getTextContent();

                        Element rate = (Element) newdoc.createElement("RATE");

                        rate.setTextContent(sourceval);

                        root.appendChild(rate);

                  }

                  Transformer transformer = TransformerFactory.newInstance()

                              .newTransformer();

                  Source source = new DOMSource(newdoc);

                  Result output = new StreamResult(arg1.getOutputPayload().getOutputStream());

                  transformer.transform(source, output);

            } catch (Exception e) {

                  e.printStackTrace();

            }

      }// end of transform

}
