Class JSONPRequestFilter

java.lang.Object

org.bch.fhir.i2b2.util.JSONPRequestFilter

All Implemented Interfaces:

javax.servlet.Filter

@WebFilter(value="/rest/*")
public class JSONPRequestFilter
extends java.lang.Object
implements javax.servlet.Filter

This filter wraps qualified requests for JSON content with that standard JSONP padding. This makes these calls accessible cross-domain using standard JSONP approaches.

To qualify for wrapping the request must be made to the /rest/* path, and contain a query parameter call jsoncallback that defines the JSONP callback method to use with the response.
