classRef -

Returns:

Throws:

ClassNotFoundException

BundleNotFoundException

getClassRef

public static Utils.ClassRef getClassRef(String classRef)

                                         BundleNotFoundException

Get a class proxy reference for the given class reference

Parameters:

classRef -

Returns:

Throws:

Exception

ClassNotFoundException

BundleNotFoundException

getClassRef

public static Utils.ClassRef getClassRef(String classRef,
                                         org.osgi.framework.Bundle bundle)
