If base and property are not
null and base is
an instance of ResourceHandler , perform the following:
If property doesn't contain : treat property
as the resource name and pass property to ResourceHandler.createResource(String)
If property contains a single : treat the content
before the : as the library name, and the content after the
: to be the resource name and pass both to ResourceHandler.createResource(String, String)
If property contains more than one : then throw
a ELException
If one of the above steps resulted in the creation of a Resource
instance, call ELContext.setPropertyResolved(true) and return
the result of Resource.getRequestPath()
