Interceptor result control

[Torben Hedstrøm <to...@gmail.com>]

Hi...

How do I control the result from within my Interceptors ?.

-I have defined :


        <interceptors>
            <interceptor name="exceptionhandler"
class="org.husejerforeningen.interceptor.ExceptionInterceptor"/>
            <interceptor-stack name="hf-default">
              <interceptor-ref name="exceptionhandler" />
              <interceptor-ref name="params" />
              <interceptor-ref name="servletConfig"/>
            </interceptor-stack>
        </interceptors>
        <default-interceptor-ref name="hf-default"/>

        <global-results>
         <result name="error">/err.jsp</result>
        </global-results>



So to test things...


public class ExceptionInterceptor implements Interceptor {
...
    public String intercept(ActionInvocation ai) throws Exception {
    ...
        ai.invoke();
        return "error";
    }
...
}


But my application does not go to the result defined by the "error"
outcome. Am I missing the point here ??.

Yep!

The result has already been rendered by the time `invoke()` returns. [1]
