CGG error on first step

I'm trying to use CGG component for the first time,
but it's already giving me a hard time.
I looked up the forum and webdetail CGG page, but couldn't find where it went wrong.

This is the step I took.
1. open CDE dashboard and press Shift+G.
2. check one of my charts (that has no parameter at this moment), copy URL, then save the dashboard.
3. confirmd that js file for chart has been created on the same folder.
4. pasted url on browser. ( localhost:8080/pentaho/plugin/cgg/api/services/draw?script=/home/Isaac/Protovis/bubble_protovisComp1.js&outputType=png )
--> I get HTTP Status 404 error page.
5. Find out that on Webdetail CGG page, they are using different url to call cgg component. (http://www.webdetails.pt/ctools/cgg.html)
So, modified my url to follow that instruaction. (localhost:8080/pentaho/content/cgg/draw?script=/home/Isaac/Protovis/bubble_protovisComp1.js&outputType=png)
--> this time, I'm getting "Sorry, We really did try" error message...
6. Checked the log and found this exceptions.

I'll appreciate if anyone can tell me where it went wrong...or experienced similar issue before.

I'm using pentaho 5.0.1 EE version on Mac OSX 10.8.5.
All CDE,CDF,CDA, and CGG are updated recently.
