Hi All,
I tried to follow the blog and I using NWDS Java editor to integrate my code with the given code as per the blog.
Code Details:
package com.sap.xi.tf.user.functions;
import com.sap.aii.mapping.api.*;
import com.sap.aii.mapping.lookup.*;
import com.sap.aii.mappingtool.tf7.rt.*;
import java.io.*;
import java.lang.reflect.*;
import java.util.*;
import com.sap.ide.esr.tools.mapping.core.Init;
import com.sap.ide.esr.tools.mapping.core.Cleanup;
import java.net.URL;
public class MM_JAVAANDGRAPHICALMAPPING {
InputAttachments inputAttachments;
InputHeader inputHeader;
InputParameters inputParameters;
DynamicConfiguration dynamicConfiguration;
OutputAttachments outputAttachments;
OutputHeader outputHeader;
OutputParameters outputParameters;
public void transform(TransformationInput in, TransformationOutput out) throws StreamTransformationException{
try
{
dynamicConfiguration = in.getDynamicConfiguration();
inputAttachments = in.getInputAttachments();
inputHeader = in.getInputHeader();
inputParameters = in.getInputParameters();
outputAttachments = out.getOutputAttachments();
outputHeader = out.getOutputHeader();
outputParameters = out.getOutputParameters();
InputStream is = (InputStream) in.getInputPayload().getInputStream();

* **************************** GuideLines for Java Mapping ********************************************************************
* You can have java mapping code INLINE if it is few lines. And if it is a big and complex code, then I recommend to isolate
* java mapping logic and develop it separately as a NORMAL java program. Import it as 'imported archive' and refer it in graphical mapping
* And then call the externally developed public method here
* Recommendation for external method signature: public ByteArrayOutputStream YourExtBussLogicMethod(InputStream is, ...)

I am getting error at statement super.transform(transformInObj, out);
Could you advice with what details I need to create transformInObj because I would like to write my java code in the same code which will provide the xml structure retrieved from URL and the same will be provided as source to graphical mapping for further mapping with IDoc.
Thanks,
Dhill
