I have an applet which I want to embed into HTML. In applet viewer in Eclipse IDE the view is this(see pict01), and when I access my index.php on local server I get this view(see pict02). I don't know what I am doing wrong. I checked it with Firefox, IE and chrome. No changes. Here is source code:
import java.util.*;
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.applet.*;
import java.net.URL;
public class WCURL extends JApplet {
//static final int WIDTH = 8;
//static final int HEIGHT = 12;
[Code] ......
I have these files in my local servers folder where I am trying to access it from(see pict03).

I compiled the applet, then put the applet in an HTML file using notepad and saved the html file in the right place for it to run correctly. The HTML file runs smoothly, but then it only shows the scrollbar part of my applet, and not the images or any text...
Why is This?????
Java Code:
import java.awt.*;
import java.applet.Applet;
import java.awt.event.*;
import javax.swing.ImageIcon;
public class Temperature_Convert extends Applet
implements AdjustmentListener {
private Image temp;
private Scrollbar bar;
private int old, newtemp = 0;
[code]....

I coded up a simple applet and some html with an applet tag and it tested out OK using the applet viewer. But it doesn't do anything (except draw a grey empty box 100x200) when executed from the application server. For the applicaton server test, I put the applet tag in the HTML Body of the JSP page i.e.
<applet code=CatApplet.class height=100 width=200> </applet>
The applet class file is in the same directory as the JSP page. The source for it is:
import java.awt.*;import java.awt.event.*;import javax.swing.*;import java.io.*;import java.net.*;
import java.util.Date;public class CatApplet extends JApplet{public void init (){setBackground(Color.green);
resize (250,100);}public void paint (Graphics g){g.drawString ("lets get some cat gui going", 35, 15);}}
Why won't my applet run when the applet tags are in the JSP page?

I work on SSH for creating a external tool to manage remote OS.
I find out the JSch library and i create the java GUI project as jar application, and worked for me very well. (i am working on Netbeans ).
I introduce the JSch library with Netbeans as follow. Right click on the Project-> Properties -> Libraries ->Compile ->Add JAR/Folder.
After that i try to transform the project to applet in order to work it form web server.
I made the transformation in all the code.
When i run the applet through the Netbeans it worked for me. When i build the project to create the jar file.
I create a folder with the my.jar file, index.html, a folder named (lib) which contains the jsch-0.1.50.jar file.
Then try to run the index.html, the GUI appear but cannot connect to the remote with the SSH, and does not give any error.
I think that the problem is that my.jar cannot communicate with the jsch-0.1.50.jar.
Why the project runs trough the Netbeans an does not run when i call it from the next html code.
index.html
Java Code:
<Html>
<Head>
<Title>Java Example</Title>
</Head>
<Body>
This is my page<br>
Below you see an applet<br>
<br>
<Applet Code="AppletUI.class" archive="my.jar" width=600 Height=700>
</Applet>

I am trying to create a simple web application which will store fingerprint of a person in database. I have a U.Are.U 4500 fingerprint device from Digital Persona. My database is MS SQL Server 2008.
Basically the web app will consist of 2 JSPs. The first JSP AskUser.jsp will ask for a user_id and will have a button Next. A user will type in his/her user_id and then click Next button.
The second JSP EnrollUser.jsp will ask for user's fingerprint and will have a button Save. User will scan his fingerprint and then click Save button which will save the fingerprint in database.
The concern I have is regarding second JSP. How to wait until the user has scan his fingerprint? I mean how will the app know that scan is done? Also can I show the fingerprint on screen when user scan his fingerprint?

Can explain difference between applet and application?
What are differences in code? How to write application?
What are differences in use? I looked for some answers, but I can't understand what they are talking about.
For example:
Application:
Called as stand-alone application as application can be executed from command prompt
Applet:
Requires some third party tool like a browser to execute
But... While I export applet in exclipse I can use it without any browser, just like application(as I and avarage user knows it).
Ok, I understand difference like "Applets cannot read from or write to hard disk files."
So. What should I use while creating what?
For example, something as simple as windows calc, some 2d simply platformer, some more expanded app, like idk, spotify or media player or whatever?
Since after update 51 of java web applets are nearly useless(as I know, maybe I'm wrong?), what is better?
Can application have GUI or it is only applets thing(stupid question?)?
Where can I find any application tutorial? Everything that I found was for applets. Why?

I am trying to design properly a simple 1to50 game (yes, the one that is so popular among mobile apps), but as a web application that allows two player games. I tried to document myself on the technologies I could use and came to the decision that some kind of Java would be suitable. I know that HTML, HTML5, CSS, JavaScript are client side languages with what I can basically design the client application that runs on a web browser. I installed Tomcat web server, configured Java Servlet API, done some research on Servlets and JSP, but I still cannot really imagine how all of this can work. Servlets form the Controller, JSP files the Model? How can I make them communicate, how can Servlets "tell" JSP files what to dynamically generate? Can JSP files communicate with JavaScript? Is JavaScript even necessary?
I thought that this question is not basically about a specific thing regarding JSP or Servlets, more about design and general concept, that is why I put this question under beginning Java.

To get starated I now want to create a simple JFrame application that works in the following way. On the opening screen I want to present 4 buttons. Based on the selection I want the JFrame to change layout and components so that the same JFrame behind the scenes contains 5 layouts but only one visible at any time. What is the best way to accomplish this? Or should I do this in another way using multiple JFrames or similar?

Using Netbeans 7.4, I have hand coded a GUI (SE desktop distributable application), created a single table database (Java DB using 'Embedded Driver' connection).
As I'm at that stage of creating a (non-CRUD) database application using Hibernate 2.0, is it possible to use the Java DB/Embedded Driver with Hibernate or does it need to be a 'localhost' connection?

I'm reasonably new to Java and NetBeans.
I'm developing an SE Java application which allows the user to view a database that I've created. I've done the data binding to a JTable but don't see any data. I've read the Derby/Java DB manual and it seems that I need to put data into this Embedded database (single table). All I want to know is how to put the data in - can I copy the files from '.netbeans-derby' folder or do I have to utilise another method?

I have an embedded browser in a standalone java app running on windows. The browser calls up web pages over the internet with no problem.
import org.eclipse.swt.browser.Browser;
final Browser browser = new Browser(group01, SWT.NONE);
browser.setBounds(0, 0, 1000, 400);
browser.setVisible(true);
browser.pack();
browser.setUrl(texturl.getText());
I have a C executable which captures and documents network traffic. I communicate with it by entering http://27.0.0.1:6500 into any browser (it works with them all). It responds with a simple html form (three buttons, a tick box, a label, and one text box).However I cannot get it to work with the embedded SWT browser.
