Java EE (Java Enterprise Edition) General Discussion

I deploy my web app. on tomcat server. The web application that consists of servlets and jsps. I am also running a quartz cron job in my application that sends email once a day to some configured addresses. In the email, I need to provide a url to a web app resource. Because I'm building the url on the fly, I need to determine the servername/host, port and the application contextPath at runtime.

How can I get this information in the quartz job class?

thanks,
