Answer 1

Spring 3.2 lists this method as deprecated ">here; I suspect what has happened is that you have compiled against a version that still had this method, but are attempting to run it in an environment in which the deprecated method has been removed. The one without the method would be more current. Check the versions of libraries in both places, and ensure that you only have one such library in each place.
