Re: RE: Adding Json to existing action
Hi,
I already use the json plugin. I have written a new action to test the plugin
and it works fine - I get my json result.
But for some reason it doesn't work with the existing action (I didn't write
this action).
Here's what I did:
* Installed the json plugin by copying it into WEB-INF/lib
* Added a mapping to struts.xml which refers to the existing
action but has a json result type and a different name.
* Added the getJsonData() method to the action with return execute();
in the body.
Now I can call the action by it name myJsonData.action but it only
returns success.

What I meant was either to use Json Plugin for struts 2. Read the
following Wiki page:
http://cwiki.apache.org/WW/json-plugin.html
The JSON plugin is bundled with Struts since 2.1.7. Or you can write your
customized Struts 2 Result type for JSON and register it in your
struts2.xml for use [does not make sense to do that if you are using 2.1.7+].
To learn how to do that, take a look at the a sample provided in struts 2
in action. That should do it as well.
Hope this helps.

I just noticed a mistake I made. When
adding the parameter to the result I also have to add a
getJsonData() method to the action, right?
I have added this method which actually calls execute().
Now I don't get null as a result anymore but I get
success which is also not what I expected.
I guess I have missed something. Since this is the first
time I use struts, I have no idea what I did wrong. Any
hints are appreciated.

Thanks for that hint. I have extended my mapping by
adding param
name=rootjsonData/param to my action
mapping's result tag. Now I don't get any
Exception and the server log looks just fine. However,
the value returned
by the action is just null.
Do you have any idea what could be wrong here?

Hi,
I need to call an existing struts action
within my
application from a
JavaScript function. I thought it might
be possible to
create an additional entry in the struts
mapping file like
this:
action name=getDataJson
class=com.mypackage.MyAction
method=getData
result type=json /
/action
and then call the action with
getDataJson.action.
Unfortunately, when I try this a
NullPointerException
occurs in the action code. It seems,
some parameters are not
properly initialized.
What I'd like to know is: what is the
recommendet way of
calling an existing action
Re: RE: Adding Json to existing action
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=rootjsonData/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?

Proccessing parameters inside Struts action
Hi, I'm using a Struts2 action to devliver JSON data. This action is calleb by an Ajax HTTP request. Now, I need to send some parameter along with the request. The sending of the parameters works fine but I don't know how to access them from within the struts action. So my question is: what is the proper way to pass POST parameters to a struts action and how do I retrieve them from within the action? Many thanks in advance.
