AFAIK, you can obtain a reference to TransactionManager by looking up in
JNDI using a vendor *specific* name. In GlassFish, the
TransactionManager is bound to java:appserver/TransactionManager in JNDI.
But that interface is *not* designed for application developers. Can't
you use /UserTransaction.getStatus()/ to see if there is already
transaction started in the thread stack or not?
