Hi, I am in the process of building a web application with struts and tiles. I am looking at access control. I was planning to simply set an attribute in session scope when a user has logged in. Each JSP page would simply check if the attribute was set and if not forward to the login page: <logic:forward name="start" /> However I get the following error when I try this: org.apache.jasper.JasperException: Exception forwarding for name start: java.lang.IllegalStateException: Cannot forward after response has been committed I was wondering if anyone has come accross this and may be able to provide some more insight. Regards, Derek.
