Creating a custom java module for excel to xml conversion.

Question

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.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Map;
import com.sap.aii.mapping.api.StreamTransformation;
import com.sap.aii.mapping.api.AbstractTrace;
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) {
this.map = 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) {
e1.printStackTrace();
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+">";
System.out.print(xmldata);
xmldata.getBytes();
wb.close();
byte by[] = xmldata.getBytes();
outputstream.write(by);
inputstream.close();
outputstream.close();
System.out.println("\n"+"File processed");
catch (Exception e) {
e.printStackTrace();
Request you to guide how to resolve this issue.
Thanks  in advance
