OTS is the OMG (as in CORBA/IIOP) API for a transaction manager and
transaction propagation. It's just an API and specification.

JTS is the OTS mapping into Java plus one interface that allows a JTS
server to hook up into the CORBA ORB.

An EJB server must implement, or use a transaction server and provide
the JTA (not JTS) interface to beans. It can do so on top of JTS/OTS, it
can use an existing JTS/OTS server, or it can do so in any other way it
sees fit. JTS/OTS is only really required for IIOP interoperability.
