[Sunetra Sen]

Hi,

I have deployed a web application in Weblogic. When i am trying to access the
first page, i am getting the following exception:--

java.lang.IllegalStateException: Attempt to change ContentType after calling
getWriter() (cannot change charset from 'ISO-8859-1' to 'UTF-8')

---------------------------------------------

The application was running successfully on Apache+Tomcat but because of a
requirement change i had to deploy the same on Apache+Weblogic using the
standard connector.

I am using Apache 2.0.52 and Weblogic 8.1 (SP4) Server and mod_wl_20.so as
connector.

Please help me out as i am very new to Weblogic. :roll:

Thanks and regards,
Sunetra
