Nikako mi ne uspjeva da pokrenem ovaj servlet.
Sta mi je ciniti?

Code:

import java.sql.*;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperPrint;
import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.util.HashMap;

import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import net.sf.jasperreports.engine.JREmptyDataSource;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperRunManager;

public class Servlet1 extends HttpServlet
{

  public void service(HttpServletRequest zahtjev, HttpServletResponse odgovor)
      throws IOException
  {
odgovor.setContentType("application/pdf");
    ServletOutputStream servletOutputStream = odgovor.getOutputStream();
    byte[] bytes=null;
    try {
       Class.forName("com.mysql.jdbc.Driver").newInstance();
         } catch (Exception ex) {
                 // handle the error
          }
            try {
                Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/imenik?useUnicode=true&characterEncoding=utf8&user=bantu&password=electronic");
             JasperReport jasperReport;
             JasperPrint jasperPrint;
                try {
                  HashMap da= new HashMap();
                  da.put("par", "%č%");
                  jasperReport = JasperCompileManager.compileReport("c:\\da1.jrxml");
                  bytes = JasperRunManager.runReportToPdf(jasperReport, da, conn);
                  odgovor.setContentLength(bytes.length);
                  servletOutputStream.write(bytes, 0, bytes.length);
                  servletOutputStream.flush();
                  servletOutputStream.close();
                    } catch (JRException e)
                     {
                       e.printStackTrace();
                     }

               } catch (SQLException ex1) {
                                     // handle any errors
                  }
   }
  }
