Re: Error: Cannot forward after response has been committed?
Ok...
Assuming you have a tiles layout definition like:
You can make the header content a tile definition by itself, and use that
definition to declare your Controller class, which will be the one with the
logic for forwarding:
And put the forward inside the HeaderController class:
public void execute(ComponentContext tileContext, HttpServletRequest
request,
HttpServletResponse response, ServletContext servletContext) throws
Exception {
HttpSession session = request.getSession(false);
if(null == session || null == session.getAttribute("loginForm")) {
response.sendRedirect("/index.jsp");
}
}
Also, make sure that your '/common/mainLayout.jsp' page doesn't have any
html code before the invocation, or it
will make a response being sent to the client.
Regards.

Re: Error: Cannot forward after response has been committed?
What if the Tiles layout composing header, menu and body. Where the Tiles Controller belongs to? Does it stick one layout?

Re: Error: Cannot forward after response has been committed?
The error happens when part of your jsp page has already been sent to the client. My recommendation would be to define a Tiles Controller (see org.apache.struts.tiles.ControllerSupport) that would do the forwarding logic. I hope this helps.
