I want to read the contents of a file "a.xls" i have kept in war. I am
creating a servlet as follows:
import java.io.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.cummins.lms.shared.Streams;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
public class ExcelUtility extends HttpServlet{
public void doGet(HttpServletRequest request, HttpServletResponse
response)
{
try {
FileInputStream is = new FileInputStream("a.xls");
Workbook workBook = Workbook.getWorkbook(is);
Sheet sheet = workBook.getSheet(0);
System.out.println(workBook.getNumberOfSheets());
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
On calling the servlet,it gives an exception:
com.google.apphosting.utils.jetty.JettyLogger warn
WARNING: Error for /excel
java.lang.NoClassDefFoundError: jxl/Workbook
