Struts2 custom interceptos not calling when validation errors coming from validation xml file?

Question

I wrote an interceptor for struts2 application and configured in struts configuration file. Here i am using this interceptor for only some actions , not for globally.So here my problem is when validation errors are coming from ActionName-validation.xml at that time my custom interceptor is not working.Please give me suggestion/solution.

Answer 1

First of all, read how the validation (and conversion) error are handled by Struts2, then move your Interceptor BEFORE the Validation/Parameters/ConversionError Interceptors

The easier way is to define a new stack with your interceptor at first (or in the middle, "exploding" the defaultStack) like follows:

<interceptor-stack name="customStack">
    <interceptor-ref name="customInterceptor"/>
    <interceptor-ref name="defaultStack"/>
</interceptor-stack>

And then apply customStack or defaultStack action by action or package by package, according to your needs.
