Annotation Type WLFilter

@Target(value=java.lang.annotation.ElementType.TYPE)
 @Retention(value=RUNTIME)
public @interface WLFilter

The WLFilter annotation is used to mark a Filter class with necessary metadata so it can be deployed without being declared in the web.xml descriptor.

Example:

  @WLFilter (
    name = "BAR",
    initParams = { @WLInitParam (name="one", value="1") }
    mapping = {"/bar/*"}
  )
  public class MyFilter implements Filter { . . . }
 

Annotating a Filter class with the above annotation is equivalent to declaring the following in the web.xml descriptor:

  . . .
  <filter>
    <filter-name>BAR</filter-name>
    <filter-class>MyFilter</filter-class>
    <init-param>
       <param-name>one</param-name>
       <param-value>1</param-value>
    </init-param>
  </filter>
  . . .
  <filter-mapping>
    <filter-name>BAR</filter-name>
    <url-pattern>/bar/*</url-pattern>
  </filter-mapping>
  . . .
