Meanwhile, Struts itself doesn't require JavaScript. The controller doesn't really even know that JavaScript exists. You can submit a form anyway you like and Struts will take what it gets.
The optional Validator package has an optional JavaScript validation mode, but you are not required to use that if you prefer not.
Changing text as users move down the list and such is a pure client-side issue. Whatever works without Struts will work just the same with Struts. Our main focus here is the part of the cycle where the request is submitted and a response is selected.
But, again, questions like this are best submitted to the USER list.

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

I've been working on some minor updates to Struts-EL, to match recent changes to the base tag library, so I've been running through some tests. I'm using WebLogic 8.1 for these tests.
I first noticed that the strutsel-exercise-taglib application dies with the following stack trace:
----------------- java.lang.NullPointerException at
org.apache.struts.util.RequestUtils.pageURL(RequestUtils.java:1591)

org.apache.strutsel.taglib.html.ELLinkTag.doStartTag(ELLinkTag.java:675)
-----------------
Line 1591 is the following (after I added a couple of debugging lines):
String pagePattern = moduleConfig.getControllerConfig().getPagePattern();
I found that "moduleConfig" is null here, but I don't know why.
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.
