IE publications compiled with HTML Executable can contain Java applets, although support for any Java applet is not guaranteed. A Java Virtual Machine is required. For instance, the Java applet below was working with Oracle Java JRE Version 6 Update 27 on Windows 7 x64.

• the built-in HTTP server must be enabled in your publication.
• add the following JavaScript script to your HEAD HTML tag:

myexample.txt

<script type="text/javascript">
window.external.StartInternalServer();
</script>

• the codebase attribute of applet tags must be explicitly written with JavaScript in the HTML document. In fact, the codebase should be set to the root path of the built-in HTTP server.

myexample.txt

<script type="text/javascript"> var localpath = window.external.GetGlobalVariable('HEBuiltInServerHost', ''); 
document.write('<applet codebase="' + localpath + 
'" code="Clock3D.class" align="bottom" width="200" height="200">'); 
</script>

• add the CLASS file(s) and any additional file(s) they require to the Page Dependencies of the HTML page that embeds the Java applets.

The following Java applet is a “3D clock”:

The HTML code used:

myexample.txt

<p class="center">
<script type="text/javascript">
var localpath = window.external.GetGlobalVariable('HEBuiltInServerHost', ''); 
document.write('<applet codebase="' + localpath + 
'" code="Clock3D.class" align="bottom" width="200" height="200">'); 
</script>
