Ok, calling it from AJAX, instead of <s:action>, seems to work, but
unfortunately it appears the JSON Plugin isn't compatible with Struts 2.1.
I'm currently using 2.1.2, but the documentation says that it works with
2.0.6. Is there any plan to update it to work with 2.1? What I'm seeing
is:
java.lang.NoSuchMethodError:
com.opensymphony.xwork2.ActionContext.get(Ljava/lang/String;)Ljava/lang/Object;
at com.googlecode.jsonplugin.JSONResult.execute(JSONResult.java:157)
at
com.opensymphony.xwork2.DefaultActionInvocation.executeResult(DefaultActionInvocation.java:355)
at
com.opensymphony.xwork2.DefaultActionInvocation.invoke(DefaultActionInvocation.java:259)
...
Thanks.
