Which one is efficient JSON or XML in case of Server client J2EE applications?

I am using Jquery in my J2EE application. I am still using XML to get pass and get the data from the 开发者_如何学Pythonserver. My client side code is very vague to see. Is it better to move from XML to JSON ?

There have been big discussions about XML vs. JSON. Speaking in performance, there is actually no way around JSON. Its just so well recognized by JavaScript. Parsing & Encoding is way way faster than XML.

Still, there is a right to exist for XML. If you got very large datastructures with lots of information for instance, XML might be a better choice.

So I think it really depends on what kind of data structure you want to transfer, but in general, I'd always prefer JSON for server->client (javascript) data transfer.
