I know that we had the previous project related to RDF and ABCL, building wrappers around the http://jena.apache.org/, but all initiatives that I know are not active anymore. I was trying to learn the best approach to use nowadays. 

[JSS][] certainly remains a key part of integrating Java code into into ABCL,
mainly because Alan Ruttenberg keeps adding features, and its users keep fixing

But JSS is just part of [contributions we ship with ABCL][abcl-contrib] that
may be used in making Lisp wrappers of Java libraries.  Of equal importance in
ABCL-CONTRIB is probably [abcl-asdf][], which allows one to refer to the
installation of Java libraries from the distributed network of Maven
annotations.   In the “project related to RDF and ABCL” (i.e. Jeannie), it is
this ability to refer to the [Jena artifacts in the ASDF definition][jeannie]
that is probably more useful than JSS itself, as it “automates” the steps that
the end user needs to perform to install the Java libraries that one is
wrapping.   Note Jeannie is probably still as active a project as it has ever
been, in that I still ensure that Jeannie works for my usage, updating the Jena
artifacts when I have the need.

For a more groovy experience in interactively working with Java code,
there exists [a substantial re-working of SLIME with
abcl-1.5.0][slime/abcl].  Work on [merging these patches with mainline
SLIME][slime/pull/502] constitutes on ongoing project.
