    def manage_exportObject(self, id='', download=None, toxml=None,
                            RESPONSE=None,REQUEST=None):
        """Exports an object to a file and returns that file."""

        ... 
            ob._p_jar.exportFile(ob._p_oid, f)
        ...

    def _importObjectFromFile(self, filepath, verify=1, set_owner=1):
        # locate a valid connection
        connection=self._p_jar
        obj=self
        ...

        ob=connection.importFile(
            filepath, customImporters=customImporters)
        ...
