form validation in struts2

[Nitesh Patel]

Hi All,

I need to validate the form which I have developed in Struts2. I need to validate it using Struts2. I am able to do simple validation using XML where my field name is something like

 <s:textfield name="firstName"/>   

But when we have field as below,

 <s:textfield name="user.firstName"/>   

Here user is our model object having different properties.

Can anybody please help me ?

You could use like this.
mention here 1.0.2 dtd.
<validators>
<field name="firstName">
<field-validator type="requiredstring">
<message>Please enter the name</message>
</field-validator>
</field>
</validators>

Hi Suraj,

Thanks for reply, but it is not working like that. We have user (object)as one property into our action and we don't want many fields.

Hi All,

I found the reason why our code doesn't work. When we use theme,

theme="simple" 

into form, it doesn't display error messages if any. But when we don't use theme attribute into

form 

then it validate it and display error messages. We don't want to use default theme as it shows fields into thier table format. Is there any way to use validation with

 theme = "simple" 

.

You can use css_xhtml theme. Or can use <s:fielderror fieldName="name_of_the_field"></s:fielderror> or <s:actionerror /> tags.
