# Class Diagram The chapter and sections can be helpful for us to understand EasyWeb framework. Form the class diagrams, we can see two parts of framework: 1. core basic objects and building * **WebContextLoadListener** Servlet context listener, initialize framework from here * **WebConfigure** Configuration of framework * **WebProcesser** Processor of objects such as WebContainer, WebController, WebFilter, WebMethod * **WebContainer** store mappings which from request path to WebMethod instance 1. handler for HTTP request * **FilterHandler** Base handler, mostly used in EasyWebFilter, hold WebMethod from WebFilter * **WebHandler** Handler used in EasyWebDispatcher, hold WebMethod from WebController * **EasyWebDispatcher** Main servlet for framework to dispatch http request * **EasyWebFilter** Main filter for framework to main servlet EasyWebDispatcher ![](https://692849660-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LOWz706pyxeJitQ0e16%2F-LOWzbSdLrH1KzTZoRd5%2F-LOWzdnaNP6AEyvSx6j5%2Feasyweb-core-classes.png?generation=1539242369129666\&alt=media) ![](https://692849660-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LOWz706pyxeJitQ0e16%2F-LOWzbSdLrH1KzTZoRd5%2F-LOWzdnc2E1j7_kJlpWA%2Feasyweb-handler-classes.png?generation=1539242369096703\&alt=media) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
