AFAIK, acs4 tcl only uses java in oracle for cms and webmail. acs 4
java (which i'm working with right now) will deploy in any servlet
2.1 container with jsp1.1 support. it should work out of the box
with tomcat and probably resin, other containers might require a
little installation tweaking. the data model appears to be identical
to the tcl version. the acs4 java is pretty interesting because
righting a package or page in it is remarkably similiar to writing
an acs4 tcl page, thanks to a precompiler. it should be relatively
easily to make an openacs java version once the data model is ported.
there is some minor use of j2ee ( so far i see it for JavaMail,
Servlet, and JDBC APIs), but no ejbs. i'm speculating now, but i
believe more oo and javaisms will make their way into the system
come acs5.
