Solved Re: Unsuccessful making widget from simple applet

Summary:
Add access key to info.plist. I added the 'AllowFullAccess' key and I see your applet-Hello Java sample on my Dashboard. Ignore what I said earlier about Cocoa-Java projects.

    <key>AllowFullAccess</key>
    <true/>


From Apple's online docs:

-----------------------8<---------------------------

Access Keys

If your widget needs resources that extend beyond your widget’s bundle or HTML, CSS, and JavaScript technologies, you need to use Dashboard’sInfo.plist Access keys into account.


Detail:
Using Access Keys

Dashboard allows you to “declare your intentions” when you:

      Access files outside of your widget bundle
      Use a Web Kit or standard browser plug-in
      Access network resources
      Run a Java applet
      Run a command-line utility
      Using a widget plug-in
-----------------------8<---------------------------


and then later ...

"If you attempt to use any of these resources without first specifying them in your widget’s information property list file, your attempt fails." Apparently without an error-message! :-)

My two cents, not based on experience but looking at Apple's example code, you're widget doesn't work because you use Java not Javascript. If you want to use Java, you'll need a widget-plugin:

I'm suggesting the plug-in because of Apple's 'Fortune' example code; that code uses a Cocoa plug-in, unlike every other example which is Javascript. Apple's documentation specifies a Cocoa-plugin so a Cocoa-Java project may work.

Sample code is from 10.4's install DVD: /Developer/Examples/ Dashboard/Fortune

I tried to make a Macintosh OS 10.4 widget from a Hello World java applet and couldn't get it to work. The full code is at: www.segal.org/java/widget/ along with a downloadable Hello Java.sit file and a copy of the applet working in the web page.

Although I know a fair amount about Java applets, I know very little about the Macintosh per se, so it is possible I am committing some basic Macintosh error. I'd appreciate if someone could point out what is wrong so I could post some cookbook applet widget code and help Java people make widgets (although the demand that is most obvious so far is from my 5 year old, who is completely obsessed with widgets, but that should be a good leading indicator).
