CFApplets seem to not be installed

Question

I am currently moving a legacy application from CF7 to CF9. One trouble I'm having is with the cfgrid tag. The applet is failing. To ensure that this is a problem with my server setup and not the applicaiton I created a test case:
<cfquery datasource="user" name="users">
select  *
from    Main_Users
order by lastname, firstname
</cfquery>
<div style="background-color:yellow" >
<h3>cfgrid Example</h3>
<i>Currently available courses</i>
<!--- cfgrid must be inside a cfform tag. --->
<cfform>
    <cfgrid
        query="users"
        name="urupdating">
    </cfgrid>
</cfform>
</div>
The java applet fails and when I click it for more details I get:
load: class coldfusion.applets.CFGridApplet.class not found.
java.lang.ClassNotFoundException: coldfusion.applets.CFGridApplet.class

Seems like I don't even have this part of CF installed. I've compared the Extenstions from the working CFAdmin to my own and don't see anything missing. If this is something internal to the installation I haven't been able to find any clues to installing it. Checking the documentation indicates that I don't need to intsall anything further.

Answer 1

I can access that .jar file through the URL -
Admin is : ApplicationName:8307/CFIDE/administrator/index.cfm
Jar file is : ApplicationName:8307/CFIDE/classes/cfapplets.jar
The problem is that CF is attempting to access that jar file through /CFIDE/classes/cfapplets.jar. Whithout specify the Application Name and port. Looking at the CFGrid documentation I dont' see  a way to specify those things. The first half of the rendered tag is:
<embed type="application/x-java-applet;version=1.3" pluginspage="http://java.sun.com/j2se/1.3/jre/index.html" code="coldfusion.applets.CFGridApplet.class" archive="/CFIDE/classes/cfapplets.jar" mayscript="true" width="300" height="300" autowidth="false" .....
So without being able to configure the archive tag I found that I could copy the CFIDE directory and place it in the applications webroot. Removing all other directories but Classes I can now get the CFGRID tag to work.
