Subject Re: JSON Property
Date Tue, 04 Jan 2011 01:48:27 GMT
well for me I do have an custom tag
the tag converts any entity into JSON, so for example i have

List<MyEntity> myEntities;

in my JSP i can do <s:iterator ....> or output as Javascript array <sx:json
value="myEntities"/> without action knowing what the output will be
formated.

and in the tag i have my own formatting rule for JSON. of course i am sure
there are tones JAVA -> JSON converter out there you can use.

this way i have more control over the output  (possibly more bug lol)

thats the way i do it......
