I too have been facing  a similar problem when trying to access the webpage below:

http://charting.bseindia.com/charting/index.asp?SYMBOL=532129

when i try to access the above page, the panel on the right where the graph is to appear, remains blank with a msg that there is a error in the page. A screenshot of this is attached. And when i click on the details, I get the following in the Java console:
