[Ravi Kiran Va]

Hi ,


Upon selecting a Country in one combo box , i am displaying all the channels related to taht Country inside another combobox

Curently i am constructing a JSOn response inside the Servlet using StringBuffer .

Constructing a JSOn response inside a servlet is some what complicated , are there any tools or API , taht will help

Thsi si what i am trying :

StringBuffer emps = new StringBuffer("{"+channel+":{");

			while(rsmt.next())
			{
				emps.append("{names:\"" + rsmt.getString(1) + "\"},");	
				
			}
			 emps.append("}");

Could anybody please guide me , if this is the correct way of constructing a JSON response using a StringBuffer .

Thanks .

Hey,

Firstly, please call me Sean...

That is correct you will not need to use StringBuffer to construct the JSON response as that is what the APIs are there to do.

Since JSON is a fairly simple concept I'm sure that any of the APIs will be able to help you achieve your requirement, personally I have only used the org.json one but perhaps there are other people who have tried others and can give you more of an insight into others on that list.

Help with what? As Sean said, generating JSON isn't rocket science. Just look at a few of the libraries and choose one that you like; you can't go wrong by much, if at all.

Help with what

I mean that there is JSON rpc , json.org , net.sf.json .

I dont know what package to pick from these things and one more question is that can i use JSONArray for this .

Thanks

Just TRY one for goodness sake. Geez.

It's actually better to use StringBuilder because it does not contain the thread-safe, synchronization overhead that StringBuffer does.

But yes, just use a JSON library.
