Re: best practices in struts 2.1 - Tiles and Convention - clean URLs with minimum number of actions
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.

I'm using struts 2.1.8.1 here and have a question about best practices in
the following situation:
I have a form page, 'register'. It takes several fields, username, password,
etc.
I want the initial form page to be rendered via GET:
http://my.server.net/register
This shows the blank form (the tile definition below), without attempting to
validate the fields.
definition name=registrationPage extends=defaultLayout
put-attribute name=content value=/WEB-INF/pages/registration.jsp/
/definition
On POST to the same URL 'http://my.server.net/register', I want to perform
validation on the form, (via register-validation.xml or Annotation). If the
form validates then perform the action that triggers the underlying business
logic. Otherwise re-display the form with validation errors (again, same
URL, 'http://my.server.net/register').
I am using the Convention plugin and the Tiles plugin. The combination of
these two seems to throw a wrench in the works.
It seems that with the Convention plugin, I can only depend on execute()
being called, or I need to define multiple actions.
The approach I'm using now works reasonably well but there must be a cleaner
way:
@ParentPackage(testing)
public class Register extends ActionSupport
{
�...@action(value=register,result...@result(name=input, type=tiles,
location=registrationPage)})
�...@skipvalidation
public String execute() throws Exception
{
return this.isBlank() ? INPUT : submit;
}
�...@action
(
value=register-submit,
results=
{
�...@result(name=input, type=tiles,
location=registrationPage),
�...@result(name=error, type=tiles,
location=registrationPage),
�...@result(name=success, type=tiles,
location=registrationSuccessfulPage)
}
)
public String executeValidate() throws Exception
{
// perform business logic
return SUCCESS;
}
private boolean isBlank()
{
return StringUtils.isBlank(this.username)
StringUtils.isBlank(this.password)
}
}
Someone can still link in to /register-submit, which isn't awful, since
validation is performed. But I'd like to minimize the number of actionable
URLs on my site and avoid writing an isBlank() method for each form.
It would seem more straightforward if I could depend on an INPUT result on
the first load of the page (with @SkipValidation), and then execute()
thereafter, with only a single action defined at the class level instead of
multiple actions at the method level.
Is this possible, and if so, what is the most appropriate way to do this via
struts 2.1?
I am addicted to the Convention plugin annotation, and I cannot do without
Tiles.
For reference, I'm using the following in struts.xml:
constant name=struts.convention.action.alwaysMapExecute value=false/
package name=testing extends=struts-default
!-- Set the tiles result type as the default for this package. --
result-types
result-type name=tiles
class=org.apache.struts2.views.tiles.TilesResult default=true/
/result-types
/package
Many thanks for any alternatives or refinements of this approach.
/ chuck

Forwarding to a Java Application
In a Web Application I need to redirect the flow of the information to a Java class nor to a Servlet or a JSP. However in the web i have found a lot of material but none mentions what i am looking for. How is this achieved? Any idea is welcome.

how to access struts2 propery from jsp or vice versa
Hello,
I am stuck in trying to access some variables from value stack in jsp
page. Is there anyway to do it easily?
Is there anyway to communicate with a bean defined in jsp with
jsp:useBean tag from struts2? I can access values in struts but not
from jsp side. ..Basically I am trying to do something similar to
%
response.sendRedirect(..url based ons:property
value=%{GRTGRTGT}/ .);
Please, tell me if and how can I accomplish something like this.
Regards,
Parminder Lehal

I have used a similar construct quite a bit, but normally, I refer to
parameters like this -
s:if test=%{#parameters['view'] != null}
view
/s:if
s:else
not view
/s:else
In cases like this, I just want to affect the way a view is rendered.
So, leaving the getter/setter off of the action is the way to go.

Re: how to access struts2 propery from jsp or vice versa
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.
