Writing to response after forward??

[Anand Wadhwani]

Be it dispatcher.include or dispatcher.forward, these are just method calls and the java execution control does comes back to caller. What if I try to write something to response after forward(). I am getting lazy in doing it on tomcat, does anyone know already if it will throw IllegalStateException or will just ignore the data wrote to response after forward?

BTW, just to share, data wrtten to response after response.sendError() are ignored and IllegalStateException is not thrown.

This is what i had in my code

  
RequestDispatcher rd = request.getRequestDispatcher"/errorPage_BusinessException.jsp");
rd.forward(request,response);
 
response.sendError(HttpServletResponse.SC_CREATED,"Error occured");
 

This was the exception i encountered (as expected)

java.lang.IllegalStateException
org.apache.coyote.tomcat5.CoyoteResponseFacade.sendError(CoyoteResponseFacade.java:325)
com.servlet.TestServlet.doGet(TestServlet.java:49)
com.servlet.TestServlet.doPost(TestServlet.java:30)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
