However, if it is the case, tiles is really silly.
The forward logic should be inside each content tile. There's no way I can move the logic into a jsp page before calling any tile, e.g. layout.jsp.
There should be a better way, otherwise, tiles is not useful at all.

You have to make sure the the "forward" or "redirect" happens before anything is written out to the HTTP response.
One way is to invoke the <logic:forward name="logon"/> the first thing in your JSP page before you call any tiles.

I tried to migrate my struts project to use tiles. Hit some problems with forward.
In a tile, I have: <logic:notPresent scope="session" name="user"> <logic:forward name="logon"/> </logic:notPresent>
If the user is not logged on, he will be directed to the logon page. It works as a standalone jsp page. However, once I put it into a tile, it is not working. The following exception is thrown: [ServletException in:/docs/SubmitFile.jsp] Exception forwarding for name logon: java.lang.IllegalStateException: Cannot forward after response has been committed'
Looks like the way tiles works is to put all the tile definition into one http response and write to the response even before the forward happens.
I tried to use logic:redirect, no exception is thrown, but the user is not directed to the logon page.
Can someone help? Thanks.
