how to Validate tabular input.
I want to make a tabular input along with validation.
For example:
IN JSP:
<% for (int i=0;i<=someBussinessLogicResultSet.size();i++) { %>
<s:textfield name="mytext" />
<% } %>
<s:submit>
Then in Action I wrote:
@Validation
public myaction extends ActionSupport{
public String execute()
{
return SUCCESS;
}
@RequiredStringValidation(message="Please enter value in text box")
public void getMytext() {return mytext;}
public void setMytext(List mytext) {this.mytext=mytext;}
private List mytext;
}
I know the above code will not work unless i remove the validations.
But however if I need a validation so that a error message is displayed on
only those text fields which are left empty by the user, how can I do so??
Although just for note I am not using scriplet as shown above but my text
fiels are within display tags.

The XML and annotation-based validation doesn't really have support for list-
based (or map-based) properties. With indexed properties, it's best to
implement a 'validate' method on your action.
Yes, it's a pain, but, before you file an improvement JIRA, I would suggest
trying to come up with a patch. I know I, for one, have been patiently waiting
on JSR-303 before I consider writing improvements to the validation framework.

I would really like to know the answer as well, how do you validate a list of
fields with annotations?
let me tweak your example a bit so it will at least work (before
validation).
(See http://struts.apache.org/2.x/docs/tabular-inputs.html)
<s:iterator value="myText" status="stat" >
<s:textfield name="myText[%{#stat.index}]" value="top"/>
</s:iterator>
public List<String> getMytext() {return mytext;}
public void setMytext(List<String> mytext) {this.mytext=mytext;}
private List<String> mytext = new ArrayList<String>();
