The Java API for JSON Processing (JSON-P) feature provides a standardized method for constructing and manipulating data to be rendered in JavaScript Object Notation (JSON).
To enable the JavaScript Object Notation Processing 1.0 feature, add the following element declaration inside the featureManager element in your server.xml file:
<feature>jsonp-1.0</feature>
If you are developing a feature that depends on the JavaScript Object Notation Processing 1.0 feature, include the following item in the Subsystem-Content header in the feature manifest file for your new feature:
com.ibm.websphere.appserver.jsonp-1.0; type="osgi.subsystem.feature"
