There are (fetch) and (store) functions in Jess, described in the same
place in the manual that discusses Java store() and fetch(); if you
store() something in Java, you can also (fetch) it in Jess; i.e.,
after the above code, you can say
(bind ?vector (fetch VECTOR"))
and have a reference to the same Vector object.

The manual does discuss calling Java methods from Jess (in chapter 2);
it's easy. Basically it just looks like
(?vector addElement "Hello")
