JSP include causes IllegalStateException: Cannot forward as OutputStream or Writer has already been obtained

Description:
Hello
 I am using Tomcat 3.1 with IIS 4.0 on Windows NT 4.0 Pentium 233 MMX machine and JDK 1.3 .
 When I include a JSP file in another JSP file the page does not come properly. 
 It shows an 'IllegalStateException: Cannot forward as OutputStream or Writer has already been obtained'.
 I have a file login.jsp which validates a user and on successful login includes another JSP file depending upon the type of user. The following error is reported

IllegalStateException: Cannot forward as OutputStream or Writer has already been obtained

The same file i had been able to run on a win 98 machine with PWS 4.0 JDK 1.2.2 and Pentium Pro 200.

Please help me to solve this problem. Any help would be appreciated.
