java - How to disable Struts Validation Interceptor? -

i'm trying build javascript / ajax uploader submits form / file upload action. when form submitted, validation interceptor prevents action being run reason, , returns 'input' result. i'm not sure why, i'd stop.

how can disable validation interceptor myaction.execute()? here's interceptors code struts.xml:

    <interceptors>         <interceptor name="appinit"             class="com.example.myapp.interceptors.appinit">         </interceptor>         <interceptor-stack name="appdefault">          <interceptor-ref name="servletconfig"/>             <interceptor-ref name="appinit" />             <interceptor-ref name="defaultstack">              <param name="exception.logenabled">true</param>              <param name="exception.loglevel">error</param>              <param name="params.excludeparams">dojo\..*,^struts\..*,^session\..*,^request\..*,^application\..*,^servlet(request|response)\..*,parameters\...*,submit</param>           </interceptor-ref>         </interceptor-stack>   </interceptors> 

here's how go bypassing validation specific action. (i'm assuming wouldn't want disable interceptor entire application.)

<action name="myaction" class="pkg.path.to.myaction">   <interceptor-ref name="appdefault">     <param name="validation.excludemethods">execute</param>     <param name="workflow.excludemethods">execute</param>   </interceptor-ref>   <result>success.jsp</result> </action> 

the validation interceptor logs errors. it's workflow interceptor checks if validation errors logged , if yes redirects view mapped input result code.

edit:
i think nested stacks causing trouble syntax parameter override , i've never tried <stack-name>.<interceptor-name>.excludemethods before. may give try though. update: above works. :)

but, instead of trying exclude execute() rename input() (which on exclude list) , add method="input" <action>. kinda makes sense file upload too.

you override validate() action (though prefer declaratively through struts.xml)

public class myaction extends actionsupport {   ...   @override   public void validate() {     setfielderrors(null);   } }
