ST_geometry import to Geometry

Hi Everyone,
i have ST_geometry column in oracle db, and i want to read this column and convert the st_gemetry to Geometry for further processing. is it possible with geometry-api.

on accessing data Oracle does return the ST_geometry in correct format , however i am not able to convert ST_GEOMETRY to some usable java object to get individual attributes.
OperatorImportFromESRIShape does not work.
i cannot use sde.ST_AStext method , since my middle tier does not allow it.
Thanks for any help,
Kim
