The class implementing ScriptEngine is loaded by reflection after being found in the classpath at META-INF/services/javax.script.ScriptEngineFactory Groovy jars have this declaration in this file: org.codehaus.groovy.jsr223.GroovyScriptEngineFactory
I believe the bundle which creates the ScriptEngine will have to use dynamic import: DynamicImport-Package: org.codehaus.groovy.jsr223 It can, then, load the class above.But you also need java.util.ServiceLoader to work, as the script engine uses that. See this: http://blog.osgi.org/2013/02/javautilserviceloader-in-osgi.html The best solution, though, is to not use ScriptEngine and expose the script engines as OSGi services... if you can. Hope that helps.
