Hi,My problem is when I am running my applet in appletviewer index.html, Its work fine but not run from the browser as http://localhost:8080/ProgressoApplication/index.html I am using "dynamic web application" in eclipse. I want all the 52 cards will be show in browser as by "appletviewer" and run as "java applet" I can be problem in code also. please check my code.
1) Card.java
package com.progresso;
import java.awt.Image;
public class Card{
private static final long serialVersionUID = 1L;
Image image;
int x;
int y;
public Card(Image image, int x, int y) //here x and y is 0-51;
{
this.image = image;
this.x = x;
this.y = y;
//System.out.println("Card is: "+this.image); // image name of the package cards.cards
}
}
2) CardDemo.java
I am running this file as java applet its working, but not on browser.
Please check can I call a CardDemoGUI constructor from CardDemo class constructor, because when I am comiling this .java file from command prompt with JDK set path, its giving ERROR.
ERROR is ----
CardDemo.java:94: cannot find symbol
symbol : class CardDemoGUI
location: class com.progresso.CardDemo
this.setContentPane(new **C**ardDemoGUI());// error on bold line,
please help me ASAP, because I am trying for three day's, please help me
am using class file that is generated in build/classes/com/progress/MyAll.class file
Code is for CardDemo.java------
