You can not write such a filter mapping. The specification does not allow the use of a * in the middle of an expression.

My suggestion would be set it up to match as far as the * in the filter mapping, and then have the filter explicitly check for the remainder

     <filter>  
         <filter-name>NewFilter</filter-name>  
         <filter-class>pack1.NewFilter</filter-class>  
     </filter>  
     <filter-mapping>  
         <filter-name>NewFilter</filter-name>  
         <url-pattern>/component/*</url-pattern>  
     </filter-mapping> 

And then in the filter...

public static final String MANAGER_SUFFIX = "/lgn/manager.jsp";
if (request.getRequestURI().endsWith(MANAGER_SUFFIX)){
  // do the work for the filter
}

My suggestions would be to ditch those URLs completely, and come up with more RESTful URLs that end with the variable part.

[chandu gattu]

you can use as <url-pattern>/component/*</url-pattern> . It will work perfectly
