http://struts.apache.org/2.x/docs/type-conversion.html
The last topic "Type Conversion Error Handling".
I had the same problem. It turns out that there's no "validation"
concept of a "type" (similar to Struts1"), however Struts 2 will give
you control over type conversion problems (similar approach, but with
more control).
So, you really don't have to do much (other than formatting the message
if the default doesn't suit your needs)

Thank you Laurie ,
Using 'Long' is the correct way to get 'required' validator worked.
But now I want show error message when user will put string or character
instead of any long value.
What validator to use?

The 'requiredstring' validator will check for both not-null and
not-empty, where 'required' only checks for non-null. If you're using a
numeric primitive type (i.e. 'long' rather than 'Long'), you can never
have a null value, so required can never fail. In that case, you need to
specify range constraints in your validation, or switch to using the
wrapper type instead of primitives.

Use "required" validator only when a field contains a number. Use

Yeah,
I am using following -

Other validators are working.
Anyway have anyone ever used "required" validator or can you use it now

to test.
Thanks

Do you have the Validation Interceptor on your Stack?

I want to validate -
1) The text box should have some value("required" validator doesn't
show
any
error message even if it's empty)..
2) The text box must have any numerical(I am using long data type)
value. I
have no clue how to do it for long.
Can anyone please help..
Thanks
