Hi, I had a very happy start on using cl-dot with java-objects, utilizing methods such as cl-dot:graph-object-points-to directly specialized on java classes: (defmethod cl-dot:graph-object-points-to ((graph (eql 'graph)) (object (java:jclass "SomeClass"))) ...) This all went very well until I realized that java objects are boxed and a second call to the same java method returning the same java object will result in a different wrapper each time, so that in lisp they aren't eql, which is what cl-dot would expect. Now I realize that at least they are equal. But is this == or Object.equals? As an aside: Is it possible to call == from lisp? I know there has been a thread "eql for java objects" some time ago. I am looking here for a practical solution about how to use cl-dot with java objects. If anybody would like to comment on how to go about it, please go ahead. Best, Kilian
