Hi,
whis is the mapping for the action as it is currently used in the application.
No json here:
<action name="getDailyAssetUtilizationReport"
class="com.pbvm.crr.web.assetcalendar.AssetCalendarAction"
method="getDailyAssetUtilizationReport">
<result>/jsp/crr_Asset_Calendar_Daily_Report.jsp</result>
</action>
This is the mapping I have created which points to the same action but with
json enabled:
<action name="getDailyAssetUtilizationReportNew"
class="com.pbvm.crr.web.assetcalendar.AssetCalendarAction"
method="getDailyAssetUtilizationReport">
<result type="json">
<param name="root">jsonData</param>
</result>
</action>
The only method I have added to the action is this:
public String getJsonData() throws Exception {
return getDailyAssetUtilizationReport();
}
Do you need any additional information?
