Analytic Application in CE7.2

Hi,

I developed a analytic application to display a pie chart in webdynpro. When I run the application, I am not able to see the pie chart. A small icon is displayed and when I click on that wheel keeps on running but no output is displayed.

Are there any specific prerequisite that we need to follow to run the analytic applications. I am following the PDF "Developing Analytics Applications with Webdynpro for Java".

Please help.

Regards
