프레임창에 배경으로 이미지를 넣고싶은데...

프레임창에 이미지 화일을 올리고 싶은데...

이 소스는 Canvas를 상속받은 BannerCanvas라는 클래스에 이미지를 띄우는 로직을 넣고, ShowFrame (Frame상속) 클래스에서 이미지를 띄웁니다....(제 계획은 이렇죠 -.-;;)

그런데, 생각되로 되질 않네요~

도와주세요~

//=========================================
// BannerCanvas.java
//=========================================

import java.applet.*;
import java.awt.*;

public class BannerCanvas extends Canvas
{
private Image bannerImg;
private int widthSize, heightSize;

public BannerCanvas( Image banner, int width, int height )
{
super();
bannerImg = banner;
widthSize = width;
heightSize = heightSize;
}

public void paint( Graphics g )
{
g.drawImage( bannerImg, 0, 0, widthSize, heightSize, this );
}
}

//============================================
// ShowFrame.java
//============================================

import java.awt.*;

public class ShowFrame extends Frame
{

TextArea ta= new TextArea(14, 60);

String grp;
String to;
String mes;

public ShowFrame(Image banner)
{
BannerCanvas bc;

bc = new BannerCanvas( banner, 450, 100 );

GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints c = new GridBagConstraints();

setLayout(gridbag);

c.fill = GridBagConstraints.BOTH;
c.weightx= 1.0;
c.weighty = 1.0;

c.gridwidth= (mes==null)?2:1;
c.gridx=0;
c.gridy=0;

gridbag.setConstraints(bc, c);
add(bc);

c.weightx= 0.0;
c.weighty = 0.0;
c.gridwidth=1;
c.gridx=0;
c.gridy=1;

c.fill= GridBagConstraints.VERTICAL;

c.anchor= GridBagConstraints.EAST;
c.gridx=1;
Button b= new Button(" Close ");
gridbag.setConstraints(b, c);
add(b);

resize(400, 300);
move(300, 300);
}

public boolean action(Event e, Object o)
{
if(o.equals(" 보내기 ")|| o.equals(" Close ")||o.equals(" OK "))
dispose();

return super.action(e,o);
}
}

//===========================================
// ShowImage.java
//===========================================

import java.applet.*;
import java.awt.*;

public class ShowImage extends Applet {

Button b= new Button("참가");

public void init()
{
Label l;

GridBagLayout gbl= new GridBagLayout();
setLayout(gbl);
GridBagConstraints c= new GridBagConstraints();
c.fill= GridBagConstraints.BOTH;

l=new Label("대화명:");
gbl.setConstraints(l, c);
add(l);

gbl.setConstraints(b, c);
add(b);

resize(300, 150);

}

public boolean action(Event e, Object s)
{
if(e.target==b)
{
Image banner = getImage(getCodeBase(), "running.gif");

ShowFrame sf = new ShowFrame(banner);
sf.show();
}
return super.action(e,s);

}
}
