Exception hibernate syntex issue

While creating hibernate query getting exception,
dont know from where I got .(don’t in front of table name )
insert into .inward_request_header (EMPLOYEE_ID, GRADE_ID, EXP_REQ_HED_ID, ORG_UNIT_ID, CREATED_BY_ID, FOR_UNIT_ID, AC_HEAD_ID, …

Maybe you configured an empty schema or catalog name?
