Set timezone in jsonwriter for date conversion
Hello,
I'm using Struts 2.3.16.3. I use the json plugin to return information
to the client (browser and ios App). The problem I have is that the
dates/times are local to my server, and since I have the option to know the
client's timezone, I would like to return the date to the client converted
to his local time. In order to do that I need to set the timezone of the
DateFormatter used by the json plugin. I don't see any issue way to do
that, apart from extending JSONWriter. Is that something possible? how I
would indicate the plugin to use my own version of JSONWriter?
Thanks
JL

Yeah, right now it's hard. I think the best option is to write your
own JSON result with all the custom stuff you need - JSONWriter &
JSONUtil. I'm going to refactor JSON plugin to be more extensible but
it won't happen till Struts 2.5.

Hello,
Let me clarify the issue I have. I would like to be able to customize
the way the JSON plugin formats the date when converting an objecto to
json. Specifically, when I'm returning a JSONResult to a client. In order
to do that I need to modify the DateFormatter used by JSONWriter so I can
change its timezone. I took a look at the code, and it seems that make that
modification is going to be hard. It would be something like this:
Extend JSONWriter to be able to use timezone with a Date(Maybe receiving
the timezone as a parameter, or using annotation at the field level)
Extend JSONUtil to call my custom JSONWriter.
Extend JSONResult to call my customer JSONUtil, by overriding the method
createJSONString. This would pretty much imply copy the whole code, as the
method has a bunch of dependences from private variables when calling
JSONUtil.
Can anyone suggest a better approach?
