getOutputStream() has already been called for this response
Help,
Why would this code:
public class Controller extends HttpServlet {
...
protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, java.io.IOException {
HTMLTagHelper tagHlpr = new HTMLTagHelper( getServletContext() );
include(request, response, "/Include/stdHead.inc");
// out.println("<html>");
// out.println("<head>");
java.io.PrintWriter out = response.getWriter();
out.println("<title>Servlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<p>pathInfo=>" + request.getPathInfo());
out.println("<p>pathTrans=>" + request.getPathTranslated());
out.println("<p>requestURI=>" + request.getRequestURI() );
out.println("<p>RealPath=>" +
getServletContext().getRealPath("." ));
out.println("<p>ServletPath=>" + request.getServletPath());
out.println("<p>QueryString=>" + request.getQueryString());
out.println("<p>ContextPath=>" + request.getContextPath());
out.println("</body>");
out.println("</html>");
out.close();
}
protected void include( HttpServletRequest request,
HttpServletResponse response,
String page )
throws ServletException, java.io.IOException {
RequestDispatcher dispatcher = request.getRequestDispatcher( page );
dispatcher.include( request, response );
} // protected void dispatch
...
}
Throws this error:
java.lang.IllegalStateException: getOutputStream() has already been called
for this response
at
org.apache.catalina.connector.ResponseBase.getWriter(ResponseBase.java:755)
at
org.apache.catalina.connector.ResponseFacade.getWriter(ResponseFacade.java:1
65)
at Controller.processRequest(Controller.java:54)
at Controller.doPost(Controller.java:88)
...
If I remove the call to include and uncomment the lines everything works
fine.
Tomcat 4.0.2
Thanks in advance for thoughts suggestion whatever I really need to mix
includes
with the PrintWriter in this application.

Hi Lance,
You should get writer before include.
