Hi,

Based on your exception there is something wrong when creating the SVG graph. Does any graph work or is it just some specific one?

cheers,

None of the charts show up on chrome and firefox. Basically, the entire application become unstable.

Hi,

I just noticed that you are using gnu.xml.dom (GNU JAXP). I have never tried that, but I’d bet its got something to do with it. Can’t you use standard DOM implementation?

cheers,

Thanks a lot for your help. I had used the gnujaxp library. By removing the jar file, application is now working well on firefox and chrome.
