Call OSGi service from sightly javascript use function

I am trying to access an OSGi service from a sightly javascript use function. Through the sling SlingScriptHelper. I can call the sling.getService(Service.class) method from javascript, but I do not know how to specify the class in javascript.

It looks like it should be possible to reference java classes using the fully qualified name or using rhino's importPackage(..).

However, I get the following exception:

org.apache.sling.scripting.sightly.SightlyException:
org.mozilla.javascript.EvaluatorException: Can't find method
org.apache.sling.scripting.core.impl.InternalScriptHelper.getService(object).
Solution

  • To do this, prepend Packages to the fully-qualified class name, e.g.

    var myService = sling.getService(Packages.com.myco.MyService);

    (where com.myco.MyService is the service interface)
