Correct it was a typo.
I have modified my Interceptor with the following internal class:
private class TimerPreResultListener
implements PreResultListener {
private long started;
private Logger log = LogManager.getLogger(TimerInterceptor.class);
public TimerPreResultListener() {
started = System.currentTimeMillis();
}
@Override
public void beforeResult(ActionInvocation invocation, String result) {
long timeDiff = System.currentTimeMillis() - started;
ActionContext ac = invocation.getInvocationContext();
ac.getParameters().put(Constants.REQUEST_TIME_KEY,new Long(timediff));
ac.getValueStack().setValue(Constants.REQUEST_TIME_KEY,new Long(timediff));
log.debug("Request Execution Time: " + timeDiff + " milliseconds.");
}
}
The interceptor's intercept method now looks like this:
@Override
public String intercept(ActionInvocation actionInvocation)
throws Exception {
actionInvocation.addPreResultListener(new TimerPreResultListener());
return actionInvocation.invoke();
}
The problem I face is I still cannot get the value to print in my JSP using the
s:property tag. Constants.REQUEST_TIME_KEY = 'seekRequestTimeKey'.
Thoughts?

Yes, I think this is exactly the issue raised in my last post. Your
result is being processed before the lines that follow the action
invocation. Insert a PreResultListener and it can do the job of
updating.
(BTW, your method is called interceptor() but it should be Intercept()
- I'm guessing that's probably a typo.)
