Subject Re: REST question

Hi Ken,

Thanks for the pointer, In fact the app uses open session in view with a
custom interceptor, but does the REST Plugin changes the struts-default and
the json-default packages when you include the
struts2-rest-plugin-2.3.16.jar?


That could explain what is happening, but, how I assing the rest-default
stack to my Rest controllers ONLY, and the other 'old' actions continue to
work with the custom stack (Spring + Open_session_in_view +
paramsPrepareParamsStack), based on package json-default? It's a rather big
application and can't be refactored to be REST only.

Thanks for your time reading an replying the question.
