hi, i want to compare the date field with the current date. for that i need current date into the validation.xml file so that i can compare it how can i implement it i m using struts2. how can we compare in validation.xml??

Using OGNL, but to be honest, I'd do this in a validate() method. Anything beyond the most simple stuff I take out of XML configuration.

You could also write a custom validator.

Thanks for the update.
May i know the advantage of using validate() instead of validation.xml

one more question-- we can do server side validations in 3 ways right,
1) using annotations
2) using validate()
3) using validation.xml

Which one will take high precendence if i am doing the validations in all the above ways for the same field/ form element.

Easier unit testing and re-use.

Honestly, I don't remember... I *think* it's XML, annotations, then validate, but could be completely wrong--it'd be easier to just test.

The precedence is
Validation.xml
annotations
validate()
