grid load data in other browser other in ie

I was developing the app in ie and it is working fine. but today I tried for some other browser, safari. when grid load data from data, exactly same data from server (java servlet) side, it is poping up error msg. incorrect xml… please help. I thought it is multi browser compatible…

problem solved by java server side.

response.setHeader(“content-type”, “text/xml;charset=UTF-8”);
I wrote
response.setHeader(“content-type”, “text/html;charset=UTF-8”);
