iReport 3.7.4 and Netbeans 6.8 problem in library

**mine0926** · 08-17-2010, 01:37 AM

I created the report in iReport 3.7.3 nad linked it in netbeans 6.8,
it is working great until i upgrade in iReport 3.7.4. I uninstall the 3.7.3 version and
install the 3.7.4, after that I try to load the program using coded program, it returns
no error, it loads the JDialog but do not show the report.

Then I try to:
* uninstall the netbeans 6.8
* uninstall (again) the iReport 3.7.4
* install netbeans 6.8
* install iReport 3.7.4
* add iReport plugins at netbeans
* add the iReport library in netbeans

but nothing change, it just load the JDialog but not the report.

Hope you can help me here.

HERE IS THE CODE:

Java Code:

import java.awt.*;
import java.sql.*;
import java.util.HashMap;
import javax.swing.*;
import net.sf.jasperreports.swing.*;
import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.engine.design.JRDesignQuery;
import net.sf.jasperreports.engine.design.JasperDesign;
import net.sf.jasperreports.engine.xml.JRXmlLoader;

public class ReportView extends JDialog {

    String file;
    String query;
    HashMap param;

    public ReportView(String file, String query, HashMap param)
    {   this.setModalityType(ModalityType.APPLICATION_MODAL);
        initComponents();
        int width = Toolkit.getDefaultToolkit().getScreenSize().width;
        int height = Toolkit.getDefaultToolkit().getScreenSize().height;
        this.setMinimumSize(new Dimension(400, 297));

        this.setLayout(new BorderLayout());
        this.add(scrollview, BorderLayout.CENTER);
        this.setPreferredSize(new Dimension(width, height));

        this.setLocation(0, 0);

        pack();

        this.file = file;
        this.query = query;
        this.param = param;

        scrollview.setVisible(false);
        pb.setVisible(true);
        pb.setIndeterminate(true);
        showReport sr = new showReport();
        sr.execute();
    }

    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new ReportView("none", null, null).setVisible(true);
            }
        });
    }

    // Variables declaration - do not modify                     
    private javax.swing.JProgressBar pb;
    private javax.swing.JScrollPane scrollview;
    // End of variables declaration                   

 class showReport extends SwingWorker<Void, Void>
    {   @Override
        protected Void doInBackground() throws Exception
        {   try
            {   String url = "jdbc:mysql://server:3306/MyDatabase";
                Class.forName("com.mysql.jdbc.Driver").newInstance();
                Connection conn = DriverManager.getConnection(url, "USER", "PASSWORD");
                
                if(query != null)
                {   JRDesignQuery aquery = new JRDesignQuery();
                    aquery.setText(query);

                    JasperDesign design = JRXmlLoader.load(file);
                    design.setQuery(aquery);

                    JasperReport report = JasperCompileManager.compileReport(design);
                    JasperPrint print = JasperFillManager.fillReport(report, null, conn);

                    JRViewer viewer = new JRViewer(print);
                    viewer.setZoomRatio(.75f);
                    viewer.setVisible(true);
                    scrollview.setVisible(true);
                    scrollview.add(viewer);
                    scrollview.setViewportView(viewer);
                    pack();
                }
                else
                {   JasperReport report = JasperCompileManager.compileReport(file);
                    JasperPrint print = JasperFillManager.fillReport(report, param, conn);

                    JRViewer viewer = new JRViewer(print);
                    viewer.setZoomRatio(.75f);
                    viewer.setVisible(true);
                    scrollview.setVisible(true);
                    scrollview.add(viewer);
                    scrollview.setViewportView(viewer);
                    pack();
                }
            }

            catch(Exception ex){ex.printStackTrace();}
            return null;
        }
        @Override
        protected void done()
        {   Toolkit.getDefaultToolkit().beep();
            pb.setIndeterminate(false);
            pb.setVisible(false);
        }
    }
}

I try to debug the project it says that

Java Code:

Have no FileObject for C:\Program Files\Java\jdk1.6.0_18\jre\lib\sunrsasign.jar
Have no FileObject for C:\Program Files\Java\jdk1.6.0_18\jre\classes

Did you check that file is exist in that location?

**mine0926** · 08-17-2010, 05:58 AM

Yes, I check the code and the actual path.

**Eranga** · 08-17-2010, 06:25 AM

If the file exist, are you sure that all the necessary libraries are included into your project? (check on project properties, on NetBeans project menu).

**mine0926** · 08-19-2010, 01:38 AM

Sorry for late reply, problem is solve now. I look for backup of the project and copy the libraries from the back up.

Thanks,

Better to keep track of all the stuff when you are backup the projects. My advice is don't do that partially. Backup make sens if you can setup the application in a different location (should be workable) rather just keep a copy of the source code.
