Actually, I noticed computeURL has a backward compatibility hack that gets the default app module config and stores it in the request scope if one isn't already there. If you do have a recent version of struts built, perhaps the webapp has an older version of struts installed. Maybe replacing it with a fresh struts.jar would work. It looks as though this should not be happening. It doesn't happen when requesting html-link.jsp in struts exercise-taglib webapp, but i havent installed struts-el. -adam k. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
