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!
