Struts2 Annotation based Validation
Using Annotation based Validation, I want to try the following:
The Validation Error message can be retrieved in our jsp using :
<s:actionerror />
<s:fielderror />
Do I have any alternative method of using the above tags ?
For eg. can I retrieve the error using session.getAttribute(actionerror) ?
Are actionerror and fielderror stored in a request or a session object ?
Please help me understand this .
Thanks,
Tauri.

Thanks Lukasz!
I tried request.getAttribute("actionerror") and
request.getAttribute("fielderror") in my jsp but it did not work.
Am I doing it the wrong way ?

I get the following log in my console:
2008-Mar-18 16:21:17,671 - DEBUG freemarker.cache - Could not find template
in cache, creating new one;
id=[template/xhtml/fielderror.ftl[en_US,UTF-8,parsed] ]

template/simple/fielderror.ftl[en_US,UTF-8,parsed] cached copy not yet

Does it have anything to do with caching of the page?
Thanks,
Tauri.

I almost always put my messages to file named package.properties in
the same folder as my action's classes.

Depends. it can be in the same ackage as the action class and named
${actionClassName}.properties, for example. The localization docs [1] gives a
set of rules for locating resource files.

Lukasz,
I tried as you advised. I get the default error message 'Please enter a
value for first name ' which is in the "message" .
Im expecting the error messaage from the properties file.
I think Im placing my properties file in the wrong location. And therefore
my validation returns me the default error message.
Im not sure where to place my properties file.
Thanks,
Tauri.

Hi,
You mess too many thing, please try like this:
@RequiredStringValidator(key = "error.required", message = "Please
enter a value for First name")
error.required = ${fieldName} is required!

Re: Struts2 Annotation based Validation
Posted by Tauri Valor <su...@gmail.com>.
Thanks again.
I tried the following:
In my action:
@RequiredStringValidator(key = "error.message", message = "")
public String getFirstName() {
return firstName;
}
I created the properties file just under my action with the name
"MyActionName.properties" with the following contents:
error.message = ${getText(firstName)} is required.
fieldFormat = ${getText(fieldName)} is not formatted properly.
But I do not the error message as: "error.message" instead of "firstName is
required"
Where am I erring ?
Thanks,
Tauri

Yes, you can, just add key = some.error.message to your annotation, like below
@RequiredStringValidator(key = "some.key")
public void setFirstName(String firstName) {
this.firstName = firstName;
}

By default s:password tag don't shows value of your password, you can
change such behaviour by adding attribute showPassword=true, but you
should consider security issue.

Re: Struts2 Annotation based Validation

Thanks Lukasz it worked for textfields using <s:textfield>
But I have the same problem when I use it for <s:password>
this is my listbox:
<tr>
<td> <s:select label="Country" name="country" headerKey="1"
headerValue="Please Select"
list="#{'AU':'Australia',
'CN':'China',
'HK':'Hong Kong',
'IN':'India',
'ID':'Indonesia',
'JP':'Japan',
'MY':'Malaysia',
'NZ':'New Zealand',
'PL':'Philippines',
'SG':'Singapore',
'KR':'South Korea',
'TW':'Taiwan',
'TH':'Thailand'}"/></td>
</tr>
And my password fields:
<tr>
<td><s:password name="pwd" label="Your Password"/></td>
</tr>
<tr>
<td><s:password name="confirmPassword" label="Confirm your Password"
/></td>
</tr>
Please suggest.
Thanks,
Tauri

But as I see, you don't use <s:textfield> for your form and that's way
you don't see values in the form. If you want to add html tags as
above, use theme=simple and s:textfield

Hi Lukasz,
Thanks for responding..
Snippet of Jsp:
<form name="myForm" method="post" action="MyAction.do" validate="true"/>
<tr>
<td width="115">First Name</td>
<td width="142"><input type="text" name="firstName" id="firstName"
class="form_field"></td>
<td>
<s:fielderror>
<s:param>firstName</s:param>
</s:fielderror>
</td>
My Struts-config:
<action name="MyAction" class="activationPendingAction">
<result name="input" type="tiles">MyForm</result>
<result name="failure" type="tiles">MyForm</result>
<result name="success" type="tiles">SuccessPage</result>
</action>
Thats the snippet of my code.
Thanks,
Tauri.

Re: Struts2 Annotation based Validation

Thanks Jeromy and Lukasz!
I could manage to get the field specific error messages using :
<s:fielderror>
<s:param>firstName</s:param>
</s:fielderror>
I have a new problem, when validating the page I get error messages as
desired.
Eg: Mandatory field validation gives out message saying "Field is
mandatory".
But when I enter the value in the textbox and click submit again, the
validation error for next is displayed correctly but entered value
disappears in the textbox which is abnormal .
Why is this happening ? Please help me understand.
Thanks,
Tauri

In Struts2 error messages are stored in the ValueStack in an object
implementing ValidationAware.
If your action extends ActionSupport, then means they're available as a
property of your action.
You can read them from any object in the ValueStack using OGNL. Have a
look at ValidationAware.
eg. to iterate through action errors:
<s:iterator value="actionErrors"></s:iterator>
They're not available in the request object. They are available in the
session object only if something puts them there for you (which is not
the default case).
The actionError tag applies a template. You may be better off creating
a custom template.

Jeromy Evans
