Can i 'intercept' output?

Hi,

in a existing spring mvc web project i want to check for some condition and then output generated html code instead of what would be shown normally, how is this possible?

Pretty much what in PHP would be:

Code:

if ( $condition ) {
  die( '<html><body>denied</body></html>' );
}

i do have the ServletResponse on this point, so i was going for:

Code:

PrintWriter pw = response.getWriter();
pw.write( "Test" );

But this does not seem to work (plus i don't know how to prevent the rest of the view to be displayed)

Any ideas?

I think a cleaner approach would be to put this condition logic within your controller and use a different "view" based upon the condition. This way you are not putting logic within your jsp.

You may use a HandlerInterceptor as shown in http://static.springsource.org/sprin...ng-interceptor

Cheers
