Hi Chuck,
i'm also addicted to convention and i do it like that:
/register!input
(i don't remember well if it is ! or some other character but that is
possible for sure)
If one call such an address his browser will land on input result with
no validation being fired.
Also if You want to depent on request method chech the REST plugin,
maybe it will suits your needs best.

Best greetings,
Pawel Wielgus.

Charles,

I haven't really found any way to get around the setup you are talking
about... If you want validation, you pretty much have to map to
different actionable URLs. From the framework's perspective, it really
can't know that you want validation or not without different request
URLs. The alternative is to try to code around it, but then your UI
logic becomes entangled into your application code.

Hello all,

I am using struts2.1.8.1 & tiles2.0.7.

The following doc says that dispatch will work, but when I setup:
http://www.vaannila.com/struts-2/struts-2-example/dispatchAction-in-struts-2-example-1.html

My page goes to the correct URL, but the action class "ProcessTest" is
not called at all; only after refresh the page, the "edit" function is
called. Someone knows why and how?

My configurations are:
===========================

(1) jsp
<s:form namespace="/Edit" action="ProcessTest">
  ... ...
  <s:submit value="Edit" theme="simple" action="edit">

</s:form>



(2) struts.xml
<package name="Edit" namespace="/Edit" extends="struts-default">
<result-types>
<result-type name="tiles"
class="org.apache.struts2.views.tiles.TilesResult"/>
</result-types>

<action name="editProcessTest" class="ProcessTest" method="edit">
  <result name="input"  type="tiles">edit_it  </result>
  <result name="error"  type="tiles">browse_it </result>
</action>



(3) In Tiles
  <definition name= "edit_degname"
template="/WEB-INF/layouts/mainLayout-page.jsp">
    <put-attribute name="title"     value="Edit" />
    <put-attribute name="body"     value="/WEB-INF/p1.jsp"  />
  </definition>

After clicking (1)."Edit", browser goes to /Edit/ProcessTest, but the
method "edit" in ProcessTest.java class never being called?

Thank you for your help!

That form doesn't look like it is calling the action... Your action is
named 'editProcessTest', but the form points to 'ProcessTest'. Are
there more pieces (spring configuration, etc.) that we need to see?

Will the Java App(let) be up and running, or will you need to launch
it with the information passed to it?

When information are sent to the web server, they are always directed towards
a Servlet, but it can be intercepted by a Filter or Listener. Even with JSP,
we're talking about a Servlet that was created automatically by the container
from the JSP page. AFAIK, these are the only classes that can interact
*directly* with the web application.

Then come the frameworks, which deliver a set of classes (again, Servlets,
Filters, Listeners...) that abstract all the complexity for us and we can
develop simpler classes that interact with the WebApp. But in reality, they
are interacting with the classes the framework provides.

With Struts2, you can create Actions, register them with the framework and
they can receive the data directly from the web pages. Struts2 will
automatically convert and inject them in the action's properties, given the
rules have been followed correctly.

I don't know if I understood your question right, so I don't know if I
answered it well.

Ciao,

Vítor Souza

I don't think an upgrade is necessary. I think you just need to
understand a little better how things work in a JSP/Servlet
environment... The page that launches the MainMenu application is
bound to have either an <applet... or <object... tag. It has been a
while for me, I can't remember which. But, if there is information
that needs passed to the MainMenu, then you need to make that
information into params. Then, when the page that launches the
MainMenu is rendered, pass the information to the MainMenu by
rendering the appropriate <param... tags.

There is an http header result type and two redirect result types that
are much better suited for this. You can use properties in the
struts.xml file as params for the result. I am on my phone, but
perhaps someone else can post an example.
