I need this applet located here link text (the same in a popup is here: http://tcip.mste.illinois.edu/applet_popup.php?num=2)

I have downloaded (actually mirrored the whole site :D ) all the jars & the js files.

one of the js (tcip.js) describes which applet will be called & from which class located in a particular jar file.

So, how can I execute/run it offline? is it like that I have to include all the jar files in a netbeans project and then run it?

As am using Java and I need this applet for a Power Grid presentation in my college.

One of the lines which I was able to get in page's source was this:

edu.uiuc.TCIP.education.summer06.lessons.lesson4.Lesson4Applet

what does this mean..? is it like all the 5-6 jar files which I have download are run simultaneously.. and then one of the jar file named "lessons" or "lessons_old_naming" is having this structure

edu.uiuc.TCIP.education.summer06.lessons.lesson4.Lesson4Applet

as in this is the package structure..? and Lesson4Applet is what I want to get executed..?

How can I get it for offline viewing/execution..?

would appreciate it..if anyone from you could get it working for me..for offline (locally executed jar) viewing.

Delving into the JS that launches that applet suggests the relevant applet element is:

<APPLET name='myApplet' WIDTH = 800 HEIGHT = 600 
        CODE='edu.uiuc.TCIP.education.summer06.lessons.lesson2.Lesson2Applet' 
        ARCHIVE='jfreechart-1.0.10.jar , jcommon-1.0.13.jar , jama-1.0.2.jar, lessons_old_naming.jar , psdataobjects.jar, psdisplayobjects.jar, anl_lpsolver.jar , zebLP.jar'>
</APPLET>

If you create an HTML with that applet element and a codebase of http://tcip.mste.illinois.edu/, it should work. Mind you, once the applet loaded in my FF, I got simply a 'black screen' (shrugs).

BTW - do you have permission from the makers of the applet and the site to use their applet?

BTW - I have tested this applet element and seen it work locally!

Later: Now I look at your question more carefully, I realize that I never really answered it correctly, because I missed the 'offline' specifics. My bad!

By adding the codebase attribute, I was 'cheating' by allowing the JRE to reach back to the originating site for all the resources. AFAIU those resources are:

  1. The Jars mentioned in the archive attribute.
  2. The images used by the applet.

This is going to be a little more tricky.

Let us assume you want the HTML to be (poorly) named OFFLINE_applet.html, and you want everything located into the powergrid directory. In that case, the structure would be..

  • powergrid
    • OFFLINE_applet.html
    • jfreechart-1.0.10.jar
    • jcommon-1.0.13.jar
    • jama-1.0.2.jar
    • lessons_old_naming.jar
    • psdataobjects.jar
    • psdisplayobjects.jar
    • anl_lpsolver.jar
    • zebLP.jar
    • applet_images
      • the images found in http://tcip.mste.illinois.edu/applet_images/

Actually, not every image in applet_images is required. This applet only uses about 20 of them AFAIR, but download all of them it and should work.

Of course, remove the 'codebase' attribute, or the JRE will still be trying to reach back to the http://tcip.mste.illinois.edu/ site for the resources!

Test it and get back to me.

Save the result of the php page as html page and open it in any browser. It the applet does not need a server connection then it will work.
