You might want to include resources in your web application that allow you to pass dynamic information to Nucleus components through the Dynamo request. Such resources include context parameters, filters, servlets, web services, and tag libraries. The resources you create need to be consistent with the J2EE (or W3C for web services) standards described in their respective specifications. After resources are created, you must register them with the web application by adding them to web.xml in accordance with the J2EE specifications.

Keep in mind that the J2EE servlets you create are processed after the servlet pipeline. Therefore, custom filters should be called just after PageFilter. Thus, PageFilter first activates the servlet pipeline; on completion, your custom filters execute.
