8. JSP: IllegalStateException problem

Does your code do any forwarding? If so, to what? You get this error if your JSP has already sent some response text (and the response buffer has been flushed) before the forward takes place. The reason being that whatever you forward to may want to discard the existing output buffer with resetBuffer. A possible cure would be to set a ...

9. IllegalStateException of pageContext.forward( )

I ensure that I have not sent any output to the client before I called the forward method. The code is as followings: <%@ page language="java" %> <%@ taglib uri="/WEB-INF/app.tld" prefix="app" %> <%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %> <%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %> in the tag it has the forward method to the other jsp page. Thanks! Stephen

11. IllegalStateException in JSP

JSP automatically creates the variable "out" by getting an output stream from the response. Therefore your line ServletOutputStream os = response.getOutputStream(); causes the exception you see. Somewhere on the there is a lovely short summary of JSP technology syntax that shows the syntax for the various tags and includes a list of the "Implicit objects" such as out - that ...

12. Why it thorws IllegalStateException ?

hello David, going thru your code, there is the possibility that your response.redirect() will be executed twice, which commits the response twice. This causes the error IllegalStateException. That is, the container will sense that the response has already been committed in the first response.sendRedirect, so upon seeing the second redirect, it will throw up the exception. You should try to work ...

26. IllegalStateException is coming if I use sendRedirect() method..

Hi Shashi, It'll be better if you use in place of response.sendRedirect("/abc/welcome.jsp"); after checking all the necessary conditions for the login stuff. This tag doesn't notify the browser about the new page. The new page is opened but you need to notice that the address in the address bar remains the same. Thank You, Nishant
