import net.sf.jasperreports.view.JasperViewer;
import java.sql.Connection;
import java.sql.DriverManager;
public class CustSys {
public static void main(String[] args) {
try {
JasperDesign jasperDesign = JRXmlLoader.load("CIS.xml");
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
Map parameters = new HashMap();
parameters.put("Title", "Customer Information");
Connection conn = null;
try {
     //String url = "jdbc:mysql://localhost/cust";
     Class.forName ("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost/cust");
catch (ClassNotFoundException e) {
System.out.println("Error loading driver: " + e.getMessage());
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, conn);
               JasperManager.printReportToPdfFile(jasperPrint,"CIS.pdf");
// JasperExportManager.exportReportToPdfFile(jasperPrint, "CIS.pdf");
JasperViewer.viewReport(jasperPrint,false);
} catch (JRException e) {
e.printStackTrace();
i have error in this coding. can anyone point out to me the error?

Hi,
I'm the same problem.
I create a simple reports with IReport.
And i want to call my report in my java code.
But i don't reach that.
Look my java code:
<%@ page import="net.sf.jasperreports.engine.JRDataSource" %>
<%@ page import="net.sf.jasperreports.engine.JRExporterParameter" %>
<%@ page import="net.sf.jasperreports.engine.JasperExportManager" %>
<%@ page import="net.sf.jasperreports.engine.JasperPrint" %>
<%@ page import="net.sf.jasperreports.engine.JasperReport" %>
<%@ page import="net.sf.jasperreports.engine.data.JRBeanCollectionDataSource" %>
<%@ page import="net.sf.jasperreports.engine.export.JRHtmlExporter" %>
<%@ page import="net.sf.jasperreports.engine.export.JRHtmlExporterParameter" %>
<%@ page import="net.sf.jasperreports.engine.export.JRXlsExporter" %>
<%@ page import="net.sf.jasperreports.engine.export.JRXlsExporterParameter" %>
<%@ page import="net.sf.jasperreports.engine.JasperCompileManager" %>
<%@ page import="net.sf.jasperreports.engine.JasperFillManager" %>
<%@ page import="net.sf.jasperreports.engine.util.JRLoader" %>
<%@ page import="net.sf.jasperreports.engine.xml.JRXmlLoader" %>
<%@ page import="java.util.Collection" %>
<%@ page import="java.util.HashMap" %>
<%@ page import="java.util.Map" %>
<%@ page import="java.util.Vector" %>
<%@ page import="java.sql.Connection" %>
<%@ page import="java.sql.DriverManager" %>
<%@ page import="java.sql.ResultSet" %>
<%@ page import="java.sql.Statement" %>
<%@ page import="net.sf.jasperreports.engine.design.JasperDesign" %>
<%@ page import="net.sf.jasperreports.engine.xml.JRXmlLoader" %>
<%@ page import="net.sf.jasperreports.engine.JRException" %>
<%@ page import="org.gjt.mm.mysql.Driver" %>
JasperReport report = null;
JasperPrint print = null;
//design compile (my error is here!!)
JasperDesign design = JRXmlLoader.load("D:/" + "reporttest.jrxml");
//report compile
report = JasperCompileManager.compileReport(design);
try {
if (connection == null) {
Class.forName(driver).newInstance();
connection = DriverManager.getConnection(base, user, pass);
catch (Exception e) {
System.err.println("Error connection");
e.printStackTrace();
HashMap params = new HashMap();
print = JasperFillManager.fillReport(report,params,connection);
And my log error:
org.apache.jasper.JasperException: org/apache/commons/digester/SetNestedPropertiesRule
at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254)
at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)
Why have I this error?
Thanks to your help me :'(
