I am trying to run some Java code I wrote in a Google Site I have created. I know there's an issue with this but I tried both of the following options:
Using the Code Wrapper gadget as described here: http://web.michaelchughes.com/how-to/embed-java-applets-in-google-sites. I used the Code Wrapper gadget from the following URL: http://hosting.gmodules.com/ig/gadgets/file/105629041657992777031/code-wrapper.xml with the following Javascript code:
<script type="text/javascript" src="http://www.java.com/js/deployJava.js"></script>
<script type="text/javascript">
/* <![CDATA[ */
var attributes = {
code: 'com.fusego.wimbeep.applet.ScreamURLApplet.class',
archive: 'http://sites.google.com/site/wimbeep/technology/wimbeeptools.jar',
width: 500,
height: 100
};
var parameters = { };
var version = '1.6';
deployJava.runApplet(attributes, parameters, version);
/* ]]> */
</script>
This does not work - I open a debug console in my Firefox browser and I see that deployJava is undefined.
Using the Embed Gadget with tags:
<_applet archive="http://sites.google.com/site/wimbeep/technology/wimbeeptools.jar" code="com.fusego.wimbeep.applet.ScreamURLApplet.class" height="400" width="400"/>
This does not work - I see that the JRE starts but there's an error and the console reports the following:
load: class com.fusego.wimbeep.applet.ScreamURLApplet.class not found.
java.lang.ClassNotFoundException: com.fusego.wimbeep.applet.ScreamURLApplet.class

This is really frustrating. I tried many combination, with and without the .class postfix in the code attribute, it just doesn't work. Any ideas?
I had encountered a similar problem, and I chose the simple expedient of hosting the applet on another site with an ordinary link posted on sites.google.com. Alternatively, this thread suggests loading the applet via java-web-start, citing this example.
Addendum: This (somewhat more transparent) example illustrates several approaches.
