Struts2 Validation

[ec hurley]

I am using Stuts 2 w/ Tiles 2. The validation is not working for me. I will post the code if anyone can help.

[David Newton]

It'd make helping a little easier.

Hi,

I can also help you if you put your code.


And for Basic you need to learn.


First of all for Struts 2 validation your xml name must specify by your Action-validation.xml.

Every field in Xml file must with same jsp field name.

When your validation done your Action method not called so if you get contains data from Action class then make data list to global. and define in validate() method.

@Override
public void validate() {
call your method which retrieve your data.
}

Hi,

No need to change more in your code.

first you have to change your validatin xml file.

validatin xml file must same name as your action class.

so, change and make it to loginAction-Validation-xml.


every thing is perfect still if you face any problem then post again your reply and question.



Thanks,
Nishan Patel.

I solved my own problem. Once I brought tiles into the mix, I had to use programmatic validation. Thanks for making me think harder.

[David Newton]

XML validation works with Tiles as well.
