What you are looking to do doesn't quite make sense so you might have to review your approach. The issue is that under normal circumstances a JSP page is called into action by a user entering a url into their web browser. You are looking to call the JSP page into action when a new phone call enters your asterisk server which doesn't fit the normal JSP model. There are ways around this problem but we probably need to know a bit more regarding what you are trying to do. Taking a guess at what you are trying to do, I would suggest: One possible solution is the AJAX model of programming which is some times used to 'simulate' server event handling. Basically your html would contain AJAX code which does a request to the server. Unlike a normal http request the server would not respond immediately. Instead it would put the servlet to sleep with a 'wait()' statement. When a fastagi event arrives the servlet would be woken up using a 'notify()' statement. The servlet can then obtain the caller id from the fastagi service and return the details to the html page. The HTML page can then take further action using javascript to display a page based on the caller id. The servlet also needs to return periodically otherwise the browser gets upset. This is non-trival coding. We have an AJAX based 'Answer bar' which we have developed which uses a similar technique to 'screen pop' a web page and I know the developers spent a fair bit of time to get it working just right. We also used the manager api rather than the fastagi, but either will probably work, the manager api simply delivers more information and doesn't require hooks in the dial plan.
