Fire off an internal ServletRequest in Tomcat

Question

I am using Quartz to schedule background tasks for a web application. Some of these tasks just fire off requests against the same web application.

I want to avoid depending on any kind of network settings (for example a request with my own domain name might not be routed properly if made from within the data center). Is there a Java API to fire off a ServletRequest and have it handled by Tomcat internally (without any actual HTTP involved)?

I still want to wrap the work into a Servlet request rather than calling the Java code for the background tasks directly, so that I can go back to regular HTTP request as a configuration option.

Tomcat-specific code is acceptable.

Answer 1

What do you want to get from that scheduled tasks? Standard web-server behavior is to get HTTP request and respond with particular data. I assume that your tasks don't need that, i.e. you want just to perform particular processing which codebase resides within the web-application.

If the assumption above is correct you can just decouple servlet/jsp logic from business-processing logic and call business-logic layer classes directly from your scheduled tasks.
