Hi Harinath, You've not mentioned the book name you're referring.
You can configure the DD to create a filter chain so that each filter is executed in a predefined order. The order of <filter-mapping> elements in the DD determines the execution order of the filters applied to web components that match the <url-pattern> tag. According to the servlet specification, the order the container uses in building the chain of filters to be applied for a particular request URI is as follows: 1. First, the <url-pattern> matching filter mappings in the same order that these elements appear in the DD. 2. Next, the <servlet-name> matching filter mappings in the same order that these elements appear in the DD. This means that a filter mapped with the <url-pattern> element is always preferred over another filter mapped with <servlet-name> element.
I hope this will help.
