IllegalStateException

[tzablock]

Here is my troubling issue:

this is the source code:

public class MovieSearchControllerServlet extends HttpServlet
{
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
{
String option = request.getParameter("option");
if(!request.isUserInRole("FSUser")
&& !request.isUserInRole("FSAdmin") && option.equals("delete"))
{
response.reset();
RequestDispatcher view = request.getRequestDispatcher("/FSWise/loginerror.jsp");
view.forward(request,response);
}

and after i access the resource i get:

java.lang.IllegalStateException: Cannot forward after response has been committed
pl.com.filmservice.web.MovieSearchControllerServlet.doGet(MovieSearchControllerServlet.java:96)
javax.servlet.http.HttpServlet.service(HttpServlet.java:697)
javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)

why is that?

tzablock,

The Java 2 Platform EE API javadocs for reset() method explicitly state that reset() may throw this exception and why. So I guess your real question is why has the response been commited? Do you have any filters or other servlets that excute before this one?
