Thanks, Bertrand.
It is odd: my BindingsValuesProvider implementing class is in a separate OSGi
bundle from the Velocity bundle, and it is defined as a service. I can see it
in the Felix console - it has a Service ID assigned to it and a Component ID.
So I would think this is a good thing. But I'm not seeing the binding in the
scripts.
My class is fairly simple:
/*
* @scr.component immediate="true" metatype="no"
* @scr.service
*
* @scr.property name="service.description" value="Test Bindings"
* @scr.property name="service.vendor" value="CU"
*
* @scr.property name="javax.script.name" value="any"
*/
public class CUBindingsValuesProvider implements BindingsValuesProvider {
public void addBindings(Bindings bindings) {
bindings.put("testData","Hello world");
}
}
In my Velocity template I attempt to access it via ${testData} and in JSP I
attempt to access it via <c:out value="${bindings.testData}"/> but nothing
shows up in either case.
I have the "javax.script.name" property set to "any", similar to the
CurrentNodeBindingsValuesProvider example on the wiki. I tried removing the
property entirely (in case "any" is the incorrect way of specifying this...
although this is what is done on the wiki page) but it did not help.

There are a few examples in [1] that are used in integration tests [2].
No configuration is needed - all active OSGi services which implement
BindingsValuesProvider are used by script engines, and the
javax.script.name service property can be used to restrict them to a
specific script engine. I guess the value of that would be "velocity"
in your case, haven't checked.
