import java.io.IOException;
import java.util.Collection;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;

import org.apache.poi.openxml4j.exceptions.InvalidFormatException;

import net.sf.jxls.exception.ParsePropertyException;
import net.sf.jxls.transformer.XLSTransformer;

public class XSLTTransformation {
    public static void main(String[] args) {
        Collection<Employee> staff = new HashSet<Employee>();
        staff.add(new Employee("Derek", 35, 3000, 0.30));
        staff.add(new Employee("Elsa", 28, 1500, 0.15));
        staff.add(new Employee("Oleg", 32, 2300, 0.25));

        Map<String, Collection<Employee>> beans = new HashMap<String, Collection<Employee>>();
        beans.put("employee", staff);
        XLSTransformer transformer = new XLSTransformer();
        try {
            transformer.transformXLS("C:/Users/hussain.a/Desktop/malay/newprojectpocdetails/temp.xls", beans, "C:/Users/hussain.a/Desktop/malay/newprojectpocdetails/proovNYOutput.xls");
        } catch (ParsePropertyException e) 
        {
            e.printStackTrace();
        } catch (InvalidFormatException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();

i have placed the jar which has this class , i am not able to identify real prob

Definitely missed library in a classpath. Just check it on more time, or ask someone else to take a fresh look :) — udalmik, Apr 02 '13 at 14:10
Depending on your IDE you also may need to add the jar's to your deployment artifact. What ide are you using? — zmanc, Apr 02 '13 at 14:10
