    Wink Java Swings

    Can anyone please help me in correcting the following code:

    package APackage1;
    import java.awt.Container;
    import java.util.HashMap;
    import net.sf.jasperreports.swing.JRViewer;
    import net.sf.jasperreports.engine.*;
    public class AViewer extends javax.swing.JFrame
    {
    public AViewer(String fileName)
    {
    this(fileName,null);
    }

    /** This method is called from within the constructor to
    * initialize the form.
    * WARNING: Do NOT modify this code. The content of this method is
    * always regenerated by the Form Editor.
    */
    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">

    setDefaultCloseOperation(javax.swing.WindowConstan ts.EXIT_ON_CLOSE);

    javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
    getContentPane().setLayout(layout);
    layout.setHorizontalGroup(
    layout.createParallelGroup(javax.swing.GroupLayout .Alignment.LEADING)
    .addGap(0, 400, Short.MAX_VALUE)
    );
    layout.setVerticalGroup(
    layout.createParallelGroup(javax.swing.GroupLayout .Alignment.LEADING)
    .addGap(0, 300, Short.MAX_VALUE)
    );

    pack();
    }// </editor-fold>

    public AViewer(String fileName,HashMap parameter)
    {
    super("View Report");
    try
    {
    JasperPrint print = JasperFillManager.fillReport
    ("C:/Documents and Settings/c.smith/Desktop/Gayu/report2.jasper", parameter);
    JRViewer viewer=new JRViewer(print);
    Container c=getContentPane();
    c.add(viewer);
    }

    catch(JRException jre)
    {
    jre.printStackTrace();
    }

    setBounds(10,10,600,500);
    setDefaultCloseOperation(DISPOSE_ON_CLOSE);


    }
    public static void main(String args[])
    {
    HashMap parameter=new HashMap();
    parameter.put("productID",1);
    parameter.put("samplenum",123.55);
    parameter.put("sampledt",17/10/2011);
    AViewer viewer=new AViewer("C:/Documents and Settings/c.smith/Desktop/Gayu/report2.jasper",parameter);
    viewer.setVisible(true);
    }
    }


    // Variables declaration - do not modify
    // End of variables declaration

    I am trying to display a Jasper Report file through a Java application. In this code, the JFrame is getting loaded, but the report is not. I am getting an error Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/groovy/control/CompilationFailedException. I dont understand why. This is the first time I am working with Jasper Reports, so please help me. And, am using NetBeans IDE 7.

    Thanks.
