Hi,
I want to do a program with .html and .jsp that has two clocks in it:



1.One classic . And 2. One that would be digital, for example: 3:07. And that the user could edit the hour in the cloks.

what jsp/java classes or other technologies can i use to do this?

thanks for any response...

Unless you are thinking of an applet, I don't see much in the way of JSP or Java in this. It's much more in the domain of DHTML.

So which way do you want to go? Applet or DHTML?

Have you tried searching Google?
It looks like there are quite a few clock applets already out there:

This one looks pretty cool:

I downloaded the source code in zip:

Exception in thread "main" java.lang.NoSuchMethodError: main

How are you running it? Applets are not applications that you can run from the command line - they don't have a "main" method. You need to open an HTML file that contains an applet tag for this particular applet in your web browser.

i need some help with this program.

I was asked to do two clocks and that the user could edit the hours, as I said in the first post.
But I was told too, that i cannot use applet.


So:
To do such a program that I could not use applet nor dhtml.
How should I do it?

is this an assignment of some sort, designed to make your life harder than necessary?

Well, what technologies can you use then? A standalone Java application? Flash?

Umm ... the same way you would do it in an applet. Are you familiar with the AWT and/or Swing drawing toolkits?

this is my program:
I put it all here, so you can run it, and see what happens
I converted it to a standalone Java application.
the program runs, and gives the time, but it stays there, it doesn't update.

What can I do so it updates?

You don't seem to ever call the start method. In applets, the method is called by the container, but the code you have is not an applet.
