Re: Struts service facade

[Musachy Barroso]

Well, you can use the plugin to "send the data back", using a "json" 
result, instead of writing to the OutputStream directly, like Joe 
mentioned. The plugin has a helper class to write to an stream, or build 
an string from an object also. I recently added an interceptor, to 
populate an action from a request containing a JSON string.

I have never used Flex, but it seems like it plays nicely with JSON:


It does, and you don't need a plugin. If you just want to get data 
back from
the server, you can send JSON and use ActionScript's 'eval' function 
to turn
that into a data structure, just like you would in JavaScript.

For rendering beans or other Java object into JSON, you might want to 
take a
look at some code that Don wrote that's sitting in the Struts sandbox. 
See:

https://svn.apache.org/repos/asf/struts/sandbox/trunk/flow/src/java/org/apache/struts/flow/json/JSONSerializer.java 


I wrote a more generalised and extensible JSON renderer at my day job, 
but
I'd need to get permission before I could post that.

You can use the JSON plugin to serialize your actions into JSON. If you
post this question on the user list, you'll probably get more answers
