How is a filter configured in the deployment descriptor?

Rating:

A filter is configured in the deployment descriptor as follows:

<filter>
       <filter-name>Filter1</filter-name>
       <display-name>filter1</display-name>
       <description>This is a test filter</description>
       <filter-class>FilterClass</filter-class>
   <icon>
      <small-icon>SmallIcon</small-icon>
      <large-icon>LargeIcon</large-icon>
   </icon>
   <init-param>
      <param-name>testfilter</param-name>
      <param-value>test</param-value>
   </init-param>
</filter>

Of these tags, the <filter-name> and <filter-class> tags are mandatory. The <init-param> tag is optional, and there can be many <init-param> tags present for a filter. Also, the <icon>, <description>, and <display-name> tags are optional.

A filter is mapped using the deployment descriptor as follows:

<filter-mapping>
   <filter-name>Filter1</filter-name>
   <url-pattern>f1</url-pattern>
</filter-mapping>
