Hello,

i am currently working on my first struts application. That is why i am
looking at the example and there are a few things i do not understand.

The tour says something about an action-mapping

<action path="/EditRegistration"

indeed there is nothing like this in the struts-config.xml

How does struts know which Action to execute? It could know that from
the name because there is an EditRegsitrationAction.class but how does
it know which jsp to use? There is a Regsitration.jsp which handles
EditRegsitration.do but i don't see a action-mapping for that. I also
don't see any form-bean definitions for the whole Registration stuff.
Are there naming conventions which handle all that? And if they exist
where do i find documentation about that.
I read the UserGuide but that does not tell about naming cenvetions for
form-beans or action-mappings.

I hope you can answer my questions.

Henning,

>From the Tour:

If you check the struts-config.xml, you'll see that the
editRegistration action is mapped to the (surprise again!), the
EditRegistrationAction; it uses a registrationForm bean, and
registration.jsp for input.

<!-- Registration form bean
<form-bean name="registrationForm"
type=""/>

<!-- Edit user registration
<action path="/editRegistration"
type=""
name="registrationForm"
scope="request"
validate="false"
input="/registration.jsp">
<forward name="success" path="/registration.jsp"/>
</action>

The fact that the path, type, and forward values are similar is simply a
convention that makes it easier to understand without memorizing the
struts-config file.

The /editRegistration.do URL is mapped to the EditRegistrationAction
class in the <actiontag shown. It's tied to the form-bean above
through the name attribute of the <actiontag.

The Action forwards to the JSP view via a call at the end of its execute
method:

return mapping.findForward( "success" );

And as you see there is a local forward for this action keyed on
"success" to "/registration.jsp". If it was absent, there would need to
be a global forward for it.

I hope this helps.

I'm a Struts newbie myself, hoping to improve my understanding through
helping others (and being corrected unmercifully).

If all the things you described where in the .war files
struts-config.xml i would not have asked, because i read how it works
in theory.

I now had a look at 1.2.9-src und 1.2.8-bin, the struts-config.xml does
not have these entries.
I mean
So i did what the tour says. I had a look at the file and did not only
look at what the tour says the file should contain.

Ah, well, I didn't know what "tour" you were looking at.

So I googled for "struts tour editregistration" and found this as the
first hit:

That's where I got the bits of the struts-config.xml file I quoted.

Good luck!
