Struts2, JQuery and JSON result to create a dynamic ajax website
Hello all,
i wrote a simple guide that explains how to use together Struts2 and
JQuery to create dynamic content with Ajax and JSON.
http://www.zulutown.com/blog/2009/07/12/ajax-dynamic-content-with-struts2-jquery-and-json-plugin/
I hope someone can appreciate it
Thank You

You're right too ;-)
I didn't want to substitute to the plugin documentation.
I'd prefer the "include properties" behaviour anyway.
I believe a good idea could be to use @JsonInclude annotation on the
entity properties to define (just ONE time on the entities) which of
their properties are "safe to return" in the json serialization
Thank You again.

Did you look at the "Excluding properties" example in the json plugin
documentation?

You're absolutely right,
but there is a "security reason", in real-world application, the
objects i get from business service, are usually JPA entities, and
putting a "full JPA entity" on the json result will lead to issues in
the case there are some properties of that object that have to kept
"hidden" to the end users.. (i.e. in the case of a "User" entity,
would a not good idea to return in the json result its hashed
password).
Your suggestion would surely lead to a "clean code" but an
unexperienced programmer might show to its website user some
information he didn't want to...

A quick look at your tutorial makes me think you are underestimating the
capability of the JSON plugin. It is fully capable of serializing most java
objects to JSON. Rather than explicitly creating a hashmap, why not put the
'item' on the action and then set a json result with item configured as the
root object.
