Can someone please explain or highlight the primary general causes of the following error:

"Unable to clear JspWriter buffer, data already written to stream"

Thanks a lot.

If you're using a forward

Try increasing your buffer size in the page directive

<%@ page buffer="16k" autoFlush="true" %>

The above tag tells the JSP to buffer the first 16k of output then flush to the client. At that point the data has been written to the stream. This is where your IOException comes from.
