          <filter-class>edesign.filter.EDesignImageFilterfilter-class>
          <init-param>
              <param-name>pathsparam-name>
              <param-value>/photos/,/lphotos/,/userHome/,   /attachments/param-value>
          init-param>
filter>
      <filter-mapping>
          <filter-name>edesignPhotoFilterfilter-name>
          <url-pattern>/photos/*.jpgurl-pattern>
      filter-mapping>
      <filter-mapping>
          <filter-name>edesignPhotoFilterfilter-name>
          <url-pattern>/lphotos/*.jpgurl-pattern>
      filter-mapping>
      <filter-mapping>
          <filter-name>edesignPhotoFilterfilter-name>
          <url-pattern>/userHome/*.jpgurl-pattern>
      filter-mapping>
      <filter-mapping>
