Hi friends, I get the same old json string using DataSourceHelper too. Please anyone guide me how to process data using a servlet and showing the chart in a "single event". I used Requestdispatcher but that seems to be a bad idea. I used DataSourceHelper.executeDataSourceServletFlow method too, but get json string on the browser I am trying to built a website and when the user clicks "go " button the data should be processed by the servlet and chart should be drawn by the html code i am following this tutorial http://code.google.com/apis/visualization/documentation/dev/dsl_get_started.html need a design suggesion!!!! Need guidance as to how should i go about it. I get proper results when i follow the tutorial step by step but donno how to integrate it. regards Akku
