Modifying The Main Filter Chain

The main filter chain is a standard servlet filter chain, and can be modified in the normal way. To insert a filter of your own, for example, you would need to:

• Write your own filter class that implements the interface javax.servlet.Filter

• Declare and configure it by adding a filter element to WEB.XML

• Insert it into the filter chain by modifying the filter chain mapping in WEB.XML
