JSP clear a buffer -- FLUSH ERROR

Question

Hai everybody!
I've 3 jsp files. The First and the Second jsp file's will be forwarded to the Third jsp file when it completed certain process in each of the page.
The problem that I faced is that, the First page can be forwarded to Third jsp file, but the Second page cant and this exception is cought.
"org.apache.jasper.JasperException: Error: Attempt to clear a buffer that's already been flushed"
So how should I solved this problem?
I tried to put <%@ page autoFlush="true" %> at the begining of the Third jsp file but still doesnt work.
in First.jsp
....< do some process here >
..<jsp:forward page="Third.jsp"/>
in Second.jsp
.....< do some process here >
..<jsp:forward page="Third.jsp"/>
in Third.jsp
<%@ page autoFlush="true" %>
....< other code goes here >
........Any help...Thanks
