ireport 3.7.4 na netbeans 6.9.1 nie zostanie wykonany - netbeans, jasper-reports, raport, netbeans-6.9, jbutton

Jestem nowy w java i jasperreport, mam problem z wykonaniem małego raportu, dodałem cały wymagany plik jar i nie napotkałem żadnych błędów.

W jaki sposób mogę utworzyć plik PDF przy użyciu automatycznie generowanego zdarzenia "mouseclicked" z jbuttonem? Poniżej znajduje się kod, który pracowałem z samouczka thainetbeans i ireport tutorial site:

final String JDBC = "com.mysql.jdbc.Driver";
final String DB = "jdbc:mysql://localhost/afemdb?user=root&password";
private Connection con;
/** Creates new form NewJPanel */
public MyiReportViewer() {
initComponents();
try{
Class.forName(JDBC).newInstance();
con =DriverManager.getConnection(DB);
}
catch(Exception e){

}
}

Odpowiedzi:

Dodaj to w swojej metodzie jButton1ActionPerformed. Nie potrzebujesz MouseClickedEvent.

try {
URL reportFileURL = getClass().getResource("C:/Documents and Settings/Lelou/Desktop/presentation/InstructorQuestionaire.jrxml");
File reportFile = new File(reportFileURL.toURI());
JasperDesign jasperDesign = JRXmlLoader.load(reportFile);
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, con);
JasperViewer jv = new JasperViewer(jasperPrint);
JDialog viewer = new JDialog(this, "Batch Report", true);
viewer.setBounds(jv.getBounds());
viewer.getContentPane().add(jv.getContentPane());
viewer.setResizable(true);
viewer.setIconImage(jv.getIconImage());
viewer.setVisible(true);
} catch (JRException exc) {
System.out.println(exc.getMessage());
} catch (URISyntaxException exs) {
System.out.println(exs.getMessage());
}

(*) Zwróć uwagę na ukośniki w nazwie ścieżki. Pozbądź się podwójnych ukośników!

Oto twój import:

import java.io.File;
import java.net.URISyntaxException;
import java.net.URL;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import javax.swing.JDialog;

import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.engine.design.JasperDesign;
import net.sf.jasperreports.engine.xml.JRXmlLoader;
import net.sf.jasperreports.view.JasperViewer;
import net.sf.jasperreports.engine.JasperPrint;

Oto potrzebne biblioteki (korzystam z iReport 4.0.1):

Większość z nich jest tutaj: C: Program FilesJasperSoftiReport-4.0.1ireportmodulesext

Sprawdź ciąg połączenia. W razie wątpliwości użyj tego konstruktora:

public MyiReportViewer() {
initComponents();
try {
Class.forName(JDBC);
//con =DriverManager.getConnection(DB);
try {
con = DriverManager.getConnection(
"jdbc:mysql://localhost:3306/afemdb?useUnicode=true&characterEncoding=utf-8",
"root", "password");
} catch (SQLException e) {
System.out.println("Con " + e);
}

} catch (ClassNotFoundException e) {
System.out.println("SQL" + e);
}
}

Jeśli nadal nie działa, musi coś być nie tak z twoim iReport.
