Struts Validation Framework

[Chinni Bujji]

Hi all,

I have some questions regarding the Validation Framework in Struts

I am writing the validator-rules.xml and validation.xml.

The validation rules are written in validation.xml

validator-rules.xml contains some predefined routines that are reusable in validation.xml

where do i need to put javascript code
and if i use javascript dont i need to write the validation.xml ?

and in the validation.xml
how can find the mask value i.e how to evaulate the regular expression ?
