In Struts, Is it possible to add a global 'json' result for a package?

Question

It seems that in order to define a json result for a struts 2 action, you have to define it seperately for each action, in the following way:

<action name="someJsonAction" class="com.something.Struts2Action">
    <result type="json">
        <param name="noCache">true</param>
        <param name="excludeNullProperties">true</param>
        <param name="root">jsonString</param>
    </result>
</action>

Is it possible to add this as a global result to a package, so that I won't have to include the 3 parameters (noCache, excludeNullProperties, and root) with each action, and instead I can just define a result named 'json' and it would know to inherit those 3 parameters which I described?

Thanks.

You should check the package if it supports a global result. — , Nov 03 '13 at 11:33
Any package, but it should be outpost to the default package. — , Nov 03 '13 at 12:17
@nikpon Well, in my package, I'm able to define global results, however they only seem to work if I don't add a `result type`, e.g `/foo.jsp` works, but ` — Ali, Nov 03 '13 at 14:37
Sometimes it works, sometimes is not working, are you sure it works if you place it to the action? — , Nov 03 '13 at 18:15

You didn't answer my question. That link is a different question. Both answers are correct. What kind of help do you need? — , Nov 04 '13 at 08:45

Yes of course, there's a way :

See the global results section in the Documentation

<global-results>
    <result name="success" type="json">
       <param name="noCache">true</param>
        <param name="excludeNullProperties">true</param>
        <param name="root">jsonString</param>
    </result>
</global-results>

In Struts, Is it possible to add a global 'json' result for a package?
