Need Help Creating a Custom Validator

[Mano Dasanayaka <ma...@mubasher.net>]

Hi all,

Can any one suggest me a good article that describes adding a custom
validator and how to configure.  Sample code along with required
configurations is also appreciated.

Thanks In Advance.

Mano

I think the question was regarding custom validators.

I'd recommend looking at [1] and any of the included validators--whichever
one comes the closest to whatever it is you're trying to validate. [2] is a
WebWork article that goes into a bit of detail, but I think looking at one of
the validators included in the distro would be helpful.

Try this:
http://opensource.atlassian.com/confluence/oss/download/attachments/4942
/validating-input.pdf?version=3

Basically, all you need to do for custom or complex validation is to
have the action in question implement Validateable, and then have a
public void validate() method that makes calls to
addActionError(String). Also check out the built-in validators that you
can apply with annotations. They're a real time-saver for simple
validations.

Is this what you were talking about?

Hi all,

Can any one suggest me a good article that describes adding a custom
validator and how to configure.  Sample code along with required
