Hi lsy,

Your message has been moderated.

Please subscribe to the user ML for such questions and then use your email 
client
See also why here http://ofbiz.apache.org/mailing-lists.html

You will get a better support , it's more fair to share with everybody  and 
people can answer you on the ML rather than directly to you
The wider the audience the better the answers you might get

Also it's more work for moderators who have to accept your messages as long as 
you have not subscribed.
I'll personally no longer accept them (other moderators still could)

Thanks

Jacques

It's been a month since I used Ofbiz.
I want to use JSON Array sent from Ajax.
How does JAVA handle this?
1. controller.xml




 


2. service.xml

 
 
 

3. crudList.ftl


4. service.java
public static Map CRUDList(DispatchContext dctx, Map context) {
Delegator delegator = dctx.getDelegator();
 Map result = ServiceUtil.returnSuccess();
 GenericValue userLogin = (GenericValue) context.get("userLogin");
 
 List reqData = UtilGenerics.checkList(context.get("data"));

 String str = reqData.get(0);
JSONArray data = new JSONArray();
data = new JSONArray(str);
...
}

**result = data.length ==> 1
When I take a JSONARray and size it, it's 1.
I don't know why.
I'd appreciate it if you could explain why.
And then, Please let me know if there is an easier way to use Java by
sending an arraylist to Ajax.

Unless I am overlooking something, you simply need to associate the key
“data” with the Java list you want to be converted to a JSON list like
this:

   result.put("data", *the java list you want to be converted in JSON*);
   return result;

The  is supposed
to convert the service result map (plus other things) to JSON
auto-magically.
