Because it is an unnecessary restriction. Different vendors use
different tree structures, and one shouldn't limit in a specification
how the tree should be formed. Also, when you say "serverspecific code",
what do you mean? You're note implying that you're hardcoding JNDI names
in your app, are you?!? ;-)
Break it out into .properties files and this should not be a problem.
But then you should consider when it is appropriate to use the TM
anyway. According to the JTA1.0 spec (p. 9, section 3.2) the TM is
mainly used by the application server. What you refer to is probably the
UserTransaction interface, whose JNDI name is also not specified. But
since the majority of applications will be (guessing here) made by using
automatic transaction demarcation I don't see that as a (big) problem.
And if you need to use client demarcated tx's: make the name
configurable through some text file or whatever.
In short, I don't think this will be a big problem in practice.
