¿Cómo puedo obtener un jPanel que está dentro de un JtabbedPane?

I'm developing a Image Editor in java, i inserted a JPanel inside a JTabbedPane, to create a JTabbedPane with tabs that rapresent the Image Filter i want to apply to the image, i don't know how to obtain a The inner JPanel of a TabbedPane to decide witch filter is selected, because when i do " jTabbedPane1.getSelectedComponent(); " i can obtain only a component not a JComponent..

anyone knows something, sorry for my english thank's a lot..

Esto es parte de mi código:

package javaapplication22;

import javax.swing.JPanel;

/**

 */
public abstract class FilterTab extends JPanel {

    public FilterTab() {

    }

    protected void ApplyFilter() {

    }

    protected void ResetFilter() {

    }

}

public class InvertFilterTab extends FilterTab {

    private InvertFilter filter;

    public InvertFilterTab ()
    {
        filter = new InvertFilter();
    }

    /**
     *
     * @param originalImage
     * @param modifiedImage
     */
    public void ApplyFilter(BufferedImage originalImage, BufferedImage modifiedImage) {
        modifiedImage = filter.filter(originalImage, modifiedImage);
    }

    @Override
    public void ResetFilter() {

    }

}

private void button1ActionPerformed(java.awt.event.ActionEvent evt) {                                        

    BufferedImage originalImage = jOriginalPanel.getImage();
  //  BufferedImage modifiedImage = new BufferedImage(
    //        originalImage.getWidth(), originalImage.getHeight(), 
      //      BufferedImage.TYPE_INT_ARGB);
    //modifiedImage = 

    FilterTab ft = jTabbedPane1.getSelectedComponent();   <--- the problem is here

            filter.filter(originalImage, modifiedImage);

    jModifiedPanel.changeImage(modifiedImage);
    jModifiedPanel.repaint();
