Is an EJB, JMS, or general-purpose Java application server a transaction manager?

It depends on the server implementation. The JTA and JTS specifications define client-, application-, and transaction manager-level operations. There is nothing to prevent a Java application server from implementing, JMS, EJB, and JTS functionality. On the other hand, it could (if available) obtain transaction manager services indirectly from another server.
