Struts 2 ajax validation unable to find interceptor class jsonValidationWorkflowStack
I'm trying to implement ajax validation in my Struts 2 application. I have included struts2-json-plugin in the build path. Whenever I start the server in Eclipse, I get the following error: Unable to find interceptor class referenced by ref-name jsonValidationWorkflowStack - interceptor-ref - file:/C:/path/struts.xml:15:60 This is what my struts.xml looks like: <struts> <constant name="struts.url.includeParams" value="all" /> <constant name="struts.devMode" value="true" /> <package name="default" extends="struts-default"> <action name="submitForm" class="action.FormAction" > <interceptor-ref
