Hi sameer,
In struts 2.1.8.1 having 'struts2-dojo-plugin-2.1.8.1.jar' file so we don't
need to use 'jsonplugin-0.34.jar' for using json. This is my understanding :)
If we are not including 'jsonplugin-0.34.jar' then we cannot use
"com.googlecode.jsonplugin.JSONResult"
With new Struts 2.1.8.1 version how to use json without using any
annotations in action.
Can someone please send me some examples for using json in this new
version of struts2.
Thanks in advance.
Regards,
Sharath.

Do something like this:
In your struts.xml define result types as follows:
<package name="package_name" extends="struts-default"
namespace="/namespace_name">
<result-types>
<result-type name="json"
class="com.googlecode.jsonplugin.JSONResult" />
</result-types>
then in the action mapping:
<action name="action_name" class="AutocompleteField "
method="getCities()">
<result type="json">
</result>
</action>
and put annotation in the getter method in your action class:
@JSON
public Map<String,String> getJson() {
return json;
}
and u can use this json map in the jsp page.
I Hope it helps!
