The config/domain.xml doesn't allow you to pick a JVM, however; only to
configure it.
In V2, you will need a completely different installation of glassfish,
because it will always use the JVM defined as AS_JAVA in the
config/asenv.conf file (that is the /path_to_glassfish/config directory;
not the domain config directory). That variable must be defined in V2.
In v3, if that variable isn't in the asenv.conf file, then glassfish
will use whatever java binary is in your path. So you could have
separate domains started in separate shells with different paths running
the different domains.
However, as always I'm curious as to what use case you have for a 64-bit
JVM -- meaning does your heap really consume more than 3.5GB? If you're
caching database values (JPA does that pretty much automatically) then
that's one reason, but I'd be interested to hear another reason if it
applies.
Also, I completely agree with Alexis that the best workaround is to use
a Java alternative :-)
