spring - Struts 2 Annotation With Interceptors not Working -

i have been trying implement interceptors in application each , works fine till time don't include interceptor annotation in action. but, when add interceptoref tag in action code below:

@interceptorrefs({       @interceptorref("mylogging")   })  public class loginaction  implements modeldriven{ 

it starts giving me exception

i using struts 2 struts2-convention-plugin , hibernate, spring , using maven dependency management.

i have following dependencies have defined in maven's pom file:

            <dependency>         <groupid>org.apache.struts</groupid>         <artifactid>struts2-core</artifactid>        <version>2.1.8.1</version>         </dependency>      <!-- struts 2 + spring plugins --> <dependency>     <groupid>org.apache.struts</groupid>     <artifactid>struts2-spring-plugin</artifactid>     <version>2.1.8.1</version> </dependency>            <!-- mysql database driver -->     <dependency>         <groupid>mysql</groupid>         <artifactid>mysql-connector-java</artifactid>         <version>5.1.9</version>     </dependency>     <!-- spring framework -->      <dependency>         <groupid>org.springframework</groupid>         <artifactid>spring</artifactid>         <version>2.5.6</version>     </dependency>     <dependency>         <groupid>org.springframework</groupid>         <artifactid>spring-web</artifactid>         <version>2.5.6</version>     </dependency>     <!-- hibernate core -->     <dependency>     <groupid>asm</groupid>     <artifactid>asm-all</artifactid>     <version>3.3</version> </dependency> <dependency>     <groupid>asm</groupid>     <artifactid>asm</artifactid>     <version>3.3</version> </dependency>    <dependency>     <groupid>org.hibernate</groupid>     <artifactid>hibernate-core</artifactid>     <version>3.6.7.final</version> </dependency> <dependency>           <groupid>org.apache.struts</groupid>       <artifactid>struts2-convention-plugin</artifactid>       <version>2.1.8.1</version>     </dependency>           <dependency>      <groupid>javax.servlet</groupid>     <artifactid>javax.servlet-api</artifactid>   <version>3.0.1</version>     <scope>provided</scope> </dependency>           <dependency>     <groupid>log4j</groupid>     <artifactid>log4j</artifactid>     <version>1.2.15</version> </dependency>   

i have placed struts.xml in src root. far think there must missing in configuration.

struts.xml file configuration:

<struts>     <constant name="struts.devmode" value="false" />      <constant name="struts.convention.package.locators.basepackage" value="com.abc.lab"/>      <constant name="struts.convention.exclude.packages" value="org.apache.struts.*,org.apache.struts2.*,org.springframework.web.struts.*,org.springframework.web.struts2.*,org.hibernate.*,warfilename.*"/>      <constant name="struts.convention.action.checkimplementsaction" value="false"/>  <constant name="struts.convention.package.locators" value="action,actions,struts,struts2"/> <package name="default" extends="struts-default" namespace="/">      <interceptors>             <interceptor name="mylogging"                  class="com.abc.lab.interceptor.logginginterceptor">             </interceptor>             <interceptor-stack name="loggingstack">                 <interceptor-ref name="mylogging" />                  <interceptor-ref name="defaultstack" />                 </interceptor-stack>         </interceptors> </package> </struts> 

if errors "unable find interceptor class referenced ref-name xyz". means package convention placing actions, not extend package interceptor defined. fix problem either 1)use @parentpackage annotation(or struts.convention.default.parent.package) passing name of package defines interceptor, or 2) create package in xml extends package defines interceptor, , use @parentpackage(or struts.convention.default.parent.package) point it.
