Hi,
I would be obliged if someone could help me out: 1) I would like to know how to submit a form using struts without using Java Script. 2) I would like to know how to display text, when the user moves through a select box. When the user moves down, I would like to display text in the side.=20 Thanks, Raghu -----Original Message----- From: adam kramer [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 23, 2003 2:10 PM To: Struts Developers List Subject: Re: Problems with exercise-taglib, link tag, or modules?

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] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
