What is JTS ?

JTS is Transaction related services and it specifies the implementation of a Transaction Manager, which supports the Java Transaction API (JTA) 1.1 Specification at the high-level and implements the Java mapping of the OMG Object Transaction Service (OTS) 1.1 Specification at the low-level. JTS uses the standard CORBA ORB/TS interfaces and Internet Inter-ORB Protocol (IIOP) for transaction context propagation between JTS Transaction Managers.

A JTS Transaction Manager provides transaction services to the parties involved in distributed transactions: the application server, the resource manager, the standalone transactional application, and the Communication Resource Manager (CRM).JTS does not support nested transactions it means it can not start a new transaction unless the previous one is completed.
