Issue in Excel to XML Conversion

Hi Gurus,

I am creating a custom java module in sap nwds 7.3 for Excel to XML Conversion. But I am getting following error

Classpath dependency validator message.

Classpath entry  will not be exported or published. Runtime ClassNotFoundExceptions may result.

I imported the Jars from a different PI system and i am using NWDS in local PC with creating a separate folder with all JARs and also imported them using build path option.

This issue is occuring for all the jars imported.

I am using following code.





import java.util.Map;



import java.util.HashMap;

import jxl.Cell;

import jxl.Workbook;

public class JavaMappingExcelToXML implements StreamTransformation{

private Map map = null;

private AbstractTrace trace = null;

public void setParameter(Map arg0) {

map = arg0; // Store reference to the mapping parameters

if (map == null) { = new HashMap();




public static void main(String args[]) { //FOR EXTERNAL STANDALONE TESTING

try {

FileInputStream fin = new FileInputStream ("c:/ashu.xls"); //INPUT FILE (PAYLOAD)

FileOutputStream fout = new FileOutputStream ("C:/Users/ashutosh.a.upadhyay/My Documents/ashuXML2.xml"); //OUTPUT FILE (PAYLOAD)

JavaMappingXLStoXML mapping = new JavaMappingXLStoXML ();

mapping.execute(fin, fout);


catch (Exception e1) {




public void execute(InputStream inputstream, OutputStream outputstream) {

String msgType = "Message Type name will come here";

String nameSpace = "Namespace Name will come here";

String xmldata = "";

try {

Workbook wb = Workbook.getWorkbook(inputstream);

xmldata ="<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"+ "<ns0:"+msgType+" "+"xmlns:ns0=\""+nameSpace+"\n">";

Cell[] cells ;

Cell[] cellNames ;

cellNames = wb.getSheet(0).getRow(0);

for(int j=1;j<wb.getSheet(0).getRows();j++){

xmldata = xmldata+"\n<Record>\n";

cells = wb.getSheet(0).getRow(j);

for(int i=0;i<wb.getSheet(0).getColumns();i++){

xmldata = xmldata+"\t<"+cellNames[i].getContents()+">"+cells[i].getContents()+"</"+cellNames[i].getContents()+">\n";


xmldata = xmldata+"</Record>";


xmldata = xmldata+"\n</ns0:"+msgType+">";




byte by[] = xmldata.getBytes();




System.out.println("\n"+"File processed");


catch (Exception e) {





Request you to guide how to resolve this issue.

Thanks  in advance

Hi Mridul,

As per your error, Please import the below class in your imports.;

And When I see your thread that its an Adapter module then why are you using an AbstractTransformation?

Please follow the bellow blog to create an adapter module to read an excel file
