2004-08-26 20:50

I get no result on the following code!

Just blank screen!

 

<%@ page errorPage="error.jsp" %>

<%@ page import="dori.jasper.engine.*" %>

<%@ page import="dori.jasper.engine.util.*" %>

<%@ page import="dori.jasper.engine.export.*" %>

<%@ page import="java.util.*" %>

<%@ page import="java.io.*" %>

<%@ page import="java.sql.Connection" %>

<%@ page import="java.sql.DriverManager" %>

<%@ page import="java.sql.SQLException" %>

 

 

<%

//Change these settings according to your local configuration

String driver = "com.mysql.jdbc.Driver";

String connectString = "jdbc:mysql://localhost/x";

String user = "y";

String password = "z" ;

 

Class.forName(driver);

Connection conn = DriverManager.getConnection(connectString, user, password);

 

/*

JasperManager jpr = new JasperManager();

jpr.printReportToPdfFile(application.getRealPath("i1.jasper"), "a.pdf");

 

*/

File reportFile = new File(application.getRealPath("i1.jasper"));

 

JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());

 

Map parameters = new HashMap();

parameters.put("ReportTitle", "Address Report");

parameters.put("BaseDir", reportFile.getParentFile());

 

JasperManager jpr = new JasperManager();

jpr.runReportToPdfFile(application.getRealPath("i1.jasper"), "a.pdf", parameters, conn);
