Hi, the problem might be because you have forgotten to import certain jar
that should contain
SystemUtil class.

Subject: Interceptor to Autheticate User
Date: Fri, 16 Feb 2007 06:17:32 -0800 (PST)
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
