NetBeans, html won't update

[yuriythebest]

right this is a newbie question. I have installed netbeans and created a java application with a single applet file for hello world. First time when I build it it and run the app an html file is created that displays it. However if I make any changes and rebuild/recompile everything it just won't update. When I rightclick myApplet.java in netbeans and select run the changes are displayed- I have tried building the project, compiling the package and compiling the actual file in the netbeans project viewer thingy but nothing.

it just won't update.

What is the "it"? The HTML might not need any changes if the class name stays the same.

[yuriythebest]

that's just it- I do not edit the html file. The applet inside the html does not update after the first compilation.

applet inside the html does not update

Is it a browser caching problem?
How does the <APPLET tag in the HTML access the class file? Does it use a jar file or just a class file?

What happens if you move the HTML and the jar file to a different folder and open the HTML in a browser?

hmm tried opening in both firefox and IE with the same results.
while a jar file is created the code in the generated html file seems to only access th class:

<APPLET codebase="classes" code="NewApplet.class" width=350 height=200></APPLET>

My "first" compilation was of a blank java project with nothing in it- when I move the file to another folder even if I put the jar and class files together with it I get a square with an X indicating it couldn't find em or something like that.

Is that everything working fine on Applet Viewer once you select run on that menu on the class file?

I get a square with an X

When you open the HTML file in a browser, there should be a java console for the java vm output messages. Copy the contents of that console here.
If you have a jar file containing the java class files, change the <APPLET tag in the HTML to include the archive=<jarfilename> attribute and remove the codebase= attribute.

When you open the HTML file in a browser, there should be a java console for the java vm output messages. Copy the contents of that console here.

You should enable that from the control panel. By default it's disable.

Depends on your browser.
On Mozilla, Java console is under Tools|Web Development
On FireFox Java console under Tools

ok I have managed to get the console but it doesn't help much. After my initial success it won't update again.

1.I create java project
2.add a file of type "java applet"
3.modify my code so it looks like so:

*/
import java.applet.Applet;
import java.awt.Graphics;

public class NewApplet extends java.applet.Applet {

/** Initialization method that will be called after the applet is loaded
* into the browser.
*/
public void init() {
// TODO start asynchronous download of heavy resources


}

public void paint(Graphics g) {
g.drawString("Hello world!", 50, 25);
}

3.then I compile it and in

F:\netbeans-5.0\javaAppNew\build

an html file appears with hello world

4. I change "Hello world!" to "hello world! 123!", compilt it and run it- inside netbeans works but when I open it through that html page it's still "hello World!"

I have tried changing the <APPLET tag in the HTML to include the archive=<jarfilename> attribute and remove the codebase= attribute but it does not help and why would I have to do that should that not be done automatically??

java is so frustrating and silly! I am very grateful for your patience with me please don't give up on me!

[yuriythebest]

yess I figured out the problem!! In firefox REFRESH= USELESS!! I have to close firefox completely and open it again then it updates. Very silly java.

[Norm]

a Browser's caching is not part of java.

[Eranga]

I don't think it's an issue with Java, since you close the Firefox document it wont update.

[yuriythebest]

ok my mistake sorry :)

[Eranga]

ok my mistake sorry :)

Which Firefox version are you using? On 3.0.1 there is a browser crash with a memory issue. But they have fix it on 3.0.3, the latest version.
