confused about validation
Hello everyone:
I am totally new to struts. I decided to go with struts 2. But the
documentation is not complete, and I believe alot of you may agree with me.
The example on this page
http://struts.apache.org/2.0.6/docs/validating-input.html says that the
validation file follows the name convention SomeAction-validaton.xml.
In the field validation example in the showcase application in struts 2
distribution, the name of the file is struts-validation.xml. Now, none
of the examples are working for me basically because none of them is
complete. The one in the show case is great but there no explanation for
the code.
For example what is the name space here in struts applications ?
Can some one look into what I did and advice me what to do next ? I have
a webpage called newAccount.jsp:
<%@ taglib prefix="s" uri="/struts-tags"%>
<s:form action="createAccount" >
<s:textfield name="firstName" label="First Name" required="true"
></s:textfield>
<s:textfield name="lastName" label="Last Name" />
</s:form>
I need to validate the fields in this page, so I did this in
Account-Validation.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
<field name="firstName">
<field-validator type="requiredstring">
<message>first name is required</message>
</field-validator>
</field>
</validators>
and in my struts.xml I did this:
<action name="createAccount" class="billing.Account">
<result name="SUCCESS">/pages/accountView.jsp</result>
<result name="ERROR">/pages/exception.jsp</result>
</action>
but nothing is happening and no validation is taking place. can any one
kindly recommend something?
Thank you.

Confluence provides a "label" feature. From "Browse Site", we can
select the label tag, and then view a list of pages by label. Right
now, we're mainly using labels to tag the "experimental" features.
Indexing a site (or a book) is not a trivial task, but it is helpful,
if someone has the time.

"Reliable" is a complex word. The HTML version of the site has a
Google search feature that seems to work well for me. On the
Confluence side, we can narrow the search to the Struts Documentation
space. But, it's still a simple keyword search.

Is 't possible (easy) to add a master index, so users can search that
page using a key word ?
So if I am looking for theme, I can easily find all the pages that deals
with this term.
I think this can help.
having a reliable search service is another option.

The problem with links like these is that the path is pointing to the
"java" folder rather than the "resources" folder. Anyone with a CLA on
file can find and fix these.
The changes won't show up on the */2.0.6/* version, since that is a
historical archive. But they will show up on the */2.x/* draft
version.

That could be done by using the Confluence include macro, so that the
content is not duplicated.

I wish I knew how to make it better, but, honestly, I don't. The wiki
format is great for group editing, but it's very difficult to make
sweeping changes to the organization.

The location of the validation error messages is determined by the theme.

The best thing might to be file JIRA tickets with very specific
suggestions, or, alternatively, file a CLA, and implement the changes
directly.

The first thing I would do is fixing the broken links. For example if
you go to the page:
http://struts.apache.org/2.0.6/docs/basic-validation.html
you'll find this error at the bottom:
An error occurred:
http://svn.apache.org/repos/asf/struts/struts2/trunk/apps/showcase/src/main/java/org/apache/struts2/showcase/validation/QuizAction-validation.xml.
The system administrator has been notified.
and all the validation examples will have the same error.
Second thing I will re factor the documentation and try to keep all the
links on one single page. For example,
I will put all the
details of selecting a type found on this page
http://struts.apache.org/2.0.6/docs/result-types.html, under the link
"Selecting Results
<http://struts.apache.org/2.0.6/docs/selecting-results.html> We setup
different results for different result codes."
on the first page of the tutorial. I you may think this doesn't make
lots of difference as the material exist already. But I the links for
detail explanation at the bottom of every page is no very obvious to
find, and it will take time for the visitor of the site to find what she
is looking for. And it's easier to search and navigate back and forth.
As you can see from questions, the answers were there, but I couldn't
reach them. This tells that the documentation is sufficient to get a
newbie started, but the information has to be placed in a handy place so
that they can be easily reached.
The problem I am running into right now is how to control the location
of the validation error. My guess is to use css,
but I am looking for an example. I have feeling that it's there
somewhere there on the site, but the problem is how to find it.
I will let you know if I noticed any thing else that can be adjusted and
provide you with the suggestion.

I'd say that someone who is learning the framework is in the best
position to know what other newbies need to know.
What specific changes could we (meaning you) make to the documentation
so that someone else wouldn't have the same problem.

Cool...
Always feel free to post with documentation
observations or make a comment directly on the Wiki
page in question; there's a growing body of
documentation editors churning away :)

Well, you *don't* have a result for "input", which is
exactly what the error message says.
Also, the built-in result names are lowercase,
"success" and "error" etc. just like in the tutorials.

*type* Exception report

*exception*

No it's not. I moved it to the package, but now I am getting error that
the action is not found !
HTTP Status 404 - /Invoice/pages/createAccount.action

*type* Status report
*message* _/Invoice/pages/createAccount.action_

(/Invoice/pages/createAccount.action) is not available._

However, the error shows that it's using wrong path for the action. If I
know how to rectify this, I this I will make a progress.

You may need to use a lowercase v in -validation.
At runtime, is the Account-validation.xml in the same package/folder
as the Java class?
