My code:

try{

System.out.println(jasperReport.getPrintOrder());//jasperReport have created exactly

jasperPrint=JasperFillManager.fillReport(jasperReport,parameters,conn);//Wrong here!!! }catch (Exception ex){

database1.closeConnection();

ex.printStackTrace();

}

 

I have putted the axe in the helve about how to use JDBC driver in an Applet.

HaHa!I resolved this problem by myself!In JBuilder you make the jar with "include all" option,then the prolbem is gone!

But annother problem is coming:the jar is very big!It is 36MB!My God!Who can tell me which jaseprReport's jar(s) must be compressed in the jar(s)?Which not?;)
