JTabbedPane上添加JPanel为何不显示？？？

JTabbedPane上添加JPanel为何不显示？？？各种方法都试了，就是不行！！！网上也没找到解决方法。希望能在这里找到答案。。以下是我的源代码，望高手指点！
JTabbedPane子类如下：
package com.fei.bean;

import java.awt.BorderLayout;
import java.awt.Dimension;

import javax.swing.JPanel;
import javax.swing.JTabbedPane;

import com.fei.main.BasicFrame;

public class LeftTabbedPaneBean extends JTabbedPane {
BasicFrame basicFrame = null;

public LeftTabbedPaneBean(BasicFrame basicFrame) {
this.basicFrame = basicFrame;
buildAndShow();
this.setPreferredSize(new Dimension(180,500));
}

public void buildAndShow() {
this.addTab("系统功能", basicFrame.getBasicFunctionPanelBean());
this.addTab("地理查询", basicFrame.getQueryPanelBean());
this.setTabPlacement(JTabbedPane.BOTTOM);
this.setVisible(true);


}

}


要添加的JPanel代码如下：
package com.fei.bean;

import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.Insets;
import java.awt.Rectangle;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.BorderFactory;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;

import javax.swing.JScrollPane;
import javax.swing.JTextField;
import javax.swing.JTree;
import javax.swing.SwingUtilities;
import javax.swing.border.CompoundBorder;
import javax.swing.border.EmptyBorder;
import javax.swing.border.TitledBorder;
import javax.swing.tree.DefaultMutableTreeNode;
import javax.swing.tree.DefaultTreeModel;
import javax.swing.tree.TreePath;

在这里先谢谢各位了。

basicFrame.getBasicFunctionPanelBean()与
basicFrame.getQueryPanelBean()这都返回你想要的JPanel了吗？

你的代码有点复杂，但是把JPanel对象添加到tab中去的过程可以简单一点，给出示意代码：

import javax.swing.*;

public class JTabbedTest extends JFrame{
	public static void main(String[] args){
		JTabbedTest frame = new JTabbedTest();

		frame.setSize(300,300);
		frame.setVisible(true);

	}

	public JTabbedTest(){
		final JTabbedPane jtp = new JTabbedPane();

		JPanel jp1 = new JPanel();
		JButton jb1 = new JButton( "This is a button!" );
		jp1.add(jb1);

		jtp.add( "first", jp1 );

		getContentPane().add( jtp );
	}
}

还有就是导入包的话 最好不要那么详细吧 看着都晕了
一句import java.awt.*就好了

这样简单的添加到一个窗口，是能添加上可以显示。但是一放到我的主界面上添加就不显示了。

道理是一样的 我感觉还是你添加的顺序有问题

谢谢各位了啊！
