AFAIK, J-Engine is the same as WLS, T-Engine is the same as WLE, which is a
different EJB engine sitting on top of the Tuxedo core (or rather, the C++
framework built on top of it that also supports the CORBA API). So I would
say that you can have distributed transactions in WLE, but will have to use
the T-Engine to do so. I think the J-Engine - WLS - is include because the
T-Engine doesn't support JSPs, Servlets or JMS, but WLS does. Although BEA
likes to market things differently, WLE and WLS are - again, AFAIK - still
unrelated products that share a version number and, in case of WLE, a box
they're wrapped in.
I have no experience with WLE's EJB performance.
