I have created a simple applet application that is embedded in a HTML. When I did compiled it, I received an error of ClassNotFoundException. I'm using Jdeveloper11gR1. Please see screenshot.
This is my error :
java.lang.ClassNotFoundException: cams.gsis.applet.CAMSApplet at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)
[Code] ....
And this is my Error on java console.

I want to embed an existing JAVA applet in to my swing application which is a standalone application. The applet is used in some other application which is not developed by me or my company. The application is open source application (So I have the source code). The entire existing application is basically one of the parts of my new application.
convert or move standalone java thread application into Tomcat server container for accessing its JNDI services? Also is it possible to schedule this thread application in Tomcat server? is it possible to keep this app in tomcat as web application and schedule in window's scheduler.
I am new to work on JNLP program. I have created a SWING program, JNLP file when i deploy the ear file i am getting 404 error. Please find the steps in details.
1.Created a dynamic web project JWStartProject in eclipse
2.Create a HelloWorld.java class under default package.
import javax.swing.*; public class HelloWorld extends JFrame { private static final long serialVersionUID = 4968624166243565348L; private JLabel label = new JLabel("Hello Java Web START!"); public HelloWorld() { super("Jave Web Start Example"); this.setSize(350, 200); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE ); this.setLayout(null);
[Code] ....
Now I exported this project as JWStartProject.war contains following code.
Created Server in Websphere Admin console
Deployed this war file under the server and started.
I have added MIME types also.
I am unable to launch the application. I am getting 404 errors. May I know where I went wrong?

I have been tasked with creating an invoice (school assignment). Part of the calculations is creating an interest depending on the amount of days between the current date entered, and invoice date entered (The program prompts the user to enter both the current and invoice dates by asking for the day, month and year).
We are also supposed to set the contructor to a default date of 1/1/1900.. but I don't know how or where to code that.
How to calculate the difference between the CurrentDate and Invoice. I have displayed the dates to the user as follows.
I have just begin to understand collections in Java. I read about the differences between LinkedList and ArrayList but have several doubts on it. I have mentioned them below
1) Why retrieving in ArrayList is faster then LinkedList?. Since both have the get method how does performance differ?.
2) How does re-sizing happens internally in ArrayList when a item is added or removed?. How slow this is compared to the pointer re-shuffling in LinkedList when a item is added or removed?.
I read that InputStream is used for byte based reading it reads 1 byte at a time.And InputStreamReader is used for charcter based reading so it reads one charcter at a time so no need to convert this first to int then read it.Here is reading using InputStream.
input=new FileInputStream("D:/input.txt"); int c; while((c=input.read())!=-1) { System.out.print((char)c); }
and here is reading using InputStreamReader
input=new FileInputStream("D:/input.txt"); reader=new InputStreamReader(input,"UTF-8"); int c;
so what is difference between InputStream and InputStreamReader in both case i have to use a Int and then read it and at the end if I want to print that data I have to cast that with "(char)c".So what is advantage of using InputStreamReader?
I know that oracle has released a statement saying that JavaFX will eventually replace Swing. What is the advantage of JavaFX? The new format, using "stage" instead of JFrame, seemed weird. Why is this change necessary? What benefit do we reap from JavaFX that Swing does not have?
Im working on my homework and it mentioned element for one exercise and an index in another, what is the difference, If Any, Between An Element And An Index?
If I am making an application using Java SE8 and I use new concepts of JavaSE8 like "Lambda Expressions" and "Default Methods".
After completing my application I give it to client who are using Java Platform less than 8 like Jdk1.7._; then will this application will work fine as it is working on JavaSE8.
a JavaSE8 application works well on Java SE7 platform.
I know this has been covered before but none of the answers made sense to me. I'm hoping there is an easy way to do this. I have 2 user inputted strings that I have converted to dates and I just want the difference in days.
My code :
import java.util.Date; import java.text.SimpleDateFormat; import java.util.Scanner; import java.text.ParseException; public class DateTest { /** * @param args the command line arguments */ public static void main(String[] args) throws ParseException {
[Code] ....
Apparently I can't just subtract the dates like I would in VB.
I have finished a Java 101 class but the most we did was create a gui for a timer program. I figure I need more training and every book I pick up wants to teach me hello world and the difference between a class and object again.
