It might be that I'm in the wrong package. Although the repl is in cl-user, and even if I change to that package the code in the previous mail has no effect.

I don't know if this is the correct way to do it, but I did:
(defparameter *debugger-hook* #'sys::%debugger-hook-function)
In the repl (from running java -jar abcl.jar), this worked as expected. However, I can't seem to get it working with the .eval function of my interpreter instance.

Short story: if you call into Lisp using the JSR-223 API, conditions are automatically rethrown as Java exceptions.
Long story: the way this is implemented is by binding *debugger-hook* to an internal, probably undocumented function, that already does what you want. It is called sys::%debugger-hook-function.

I should add that a solution from inside CL would also work. I'm using
the
ABCL eval to execute all code, so maybe I could wrap the call with
something
like this:
(handler-case (... do-stuff ...) (... catch CL-condition + throw java exception ...))
I don't know if that would work. Also, my CL skills are not good enough
to
finish the code above (how do I capture all conditions?), so help would
be
appreciated.

Hi again, :)
I'm currently running CL-code from java. The gui is completely
implemented
on the java side. It would be nice if all errors occuring inside abcl
could
be captured from the java side (to be displayed in the gui as an
error). Is
that possible?
