Error: Cannot forward after response has been committed?

2005-09-01 Thread 梁炳場 
Within a Tiles layout,
I try to forward to another jsp when a bean not exist?

But it leads to the subject line error message?

In the header layout jsp, I put this

logic:notPresent scope=session name=loginForm
jsp:forward page=/index.jsp/
/logic:notPresent
  
If it is not allowed or it is not a good way,
what is the better way or another way to do so?

Thanks
PC Leung

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.

What if the Tiles layout composing header, menu and body.

Where the Tiles Controller belongs to?
Does it stick one layout?

Thanks

Ok... 

Assuming you have a tiles layout definition like:

definition name=.basic.layout path=/common/mainLayout.jsp
put name=header value=/common/headerTile.jsp /
put name=content value= /
put name=footer value=/common/footerTile.jsp /
/definition

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:

definition name=.basic.layout path=/common/mainLayout.jsp
put name=header value=.basic.layout.header /
put name=content value= /
put name=footer value=/common/footerTile.jsp /
/definition

definition name=.basic.layout.header page=/common/headerTile.jsp
controllerClass=my.package.HeaderController
/definition


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 tiles:insert attribute=header / invocation, or it 
will make a response being sent to the client.

Regards.
