i would like to expand my existing webapp by adding RESTful ws. i do not want to create a separate webapp which would serve solely as web service.
but as soon as i add REST plugin to th classpath of my struts2 based webapp, all actions (which worked correctly before) stop working and i get errors:
java.lang.NoSuchMethodException <...> MyActionName.index().
i thought that it could be solved by reconfiguring "ActionMapper"s. i configured that in this way:
<constant name="struts.mapper.prefixMapping" value="/ws/rest:rest,:struts"/>
but this does not solves the problem. "normal" actions throw "Cannot handle CGLIB enhanced proxies with multiple callbacks"..
i suggest to implement conditional enabling (based on the namespace of the request) of the REST plugin. this can be done by changing RestActionProxyFactory class a little bit. my solution (see the patch) adds a "namespace" property (with setter only). that property has default value or can have injected a config value named "struts.rest.namespace". the default value is "/" which means that after update the functionality of the plugin will remain the same unless one adds a config like:
<constant name="struts.rest.namespace" value="/rest" />
