Interceptor to Autheticate User

[manoj sinha <ma...@yahoo.com>]

Hi,
Wiil appreciate if some one come with Solution!!
I am writing customized Authentication Interceptor.It Checks username & password from database by calling EJBs.
Code is Here:
public class AuthenticationInterceptor extends LoginSupport implements Interceptor {

    public void destroy() {
        }

    public void init() {
        }

    public String intercept(ActionInvocation actionInvocation) throws Exception {
       
        InitialContext jndiContext =SystemUtil.getIntialcontext();
        Object ref = jndiContext.lookup("Login");
        Authentication auth =null;
        Encryption encrypt = new Encryption();
        String encryptPassword = encrypt.encryptString(getPassword());
        auth = (Authentication) new AuthenticationFactory().getAuthenticat(Constants.AUTHENTICATION_MODE);
        Vector loginVector =auth.doAuthenticate(getUsername(),getPassword()); 
               
        
        if(loginVector!=null){
            if(((String)loginVector.elementAt(0)).equals("success")){
            return actionInvocation.invoke();
        }
            return Action.ERROR;
        }
        return Action.INPUT;
    }
    }

Here LoginSupport class contains getter/setter methods.
I hace defined Interceptor Stack that is like
<interceptor name="userAuthentication" class="com.....AuthenticationInterceptor"/>
<interceptor-stack name="login">
              <interceptor-ref name="userAuthentication"/>
              <interceptor-ref name="defaultStack"/>
          </interceptor-stack>
But Error is :
[[default]] Servlet.service() for servlet default threw exception
java.lang.NoClassDefFoundError: com/...../...../util/SystemUtil
    at com......AuthenticationInterceptor.intercept(AuthenticationInterceptor.java:26)
    at com.opensymphony.xwork2.DefaultActionInvocation.invoke(DefaultActionInvocation.java:200)
    at org.apache.struts2.impl.StrutsActionProxy$1.call(StrutsActionProxy.java:27)
    at org.apache.struts2.impl.StrutsActionProxy$1.call(StrutsActionProxy.java:26)
 Will be Obliged if suggestion comes...
Thanks
Manoj

It looks like SystemUtil class is not available on the classpath.
