I downloaded StartOzServer.oz into a suited directory. The file ob-oz.el had to be adapted for looking for StartOzServer.oz in that directory. Now executing (C-C C-C) on a code block the process Org-babel-OPI-socket is started but now I get the error message:
Org-babel: executing Oz expression Create OPI socket for evaluating expressions open-network-stream: make client process failed: Connection refused, :name, *Org-babel-OPI-socket*, :buffer, nil, :host, localhost, :service, 6001, :nowait, nil If I execute (C-C C-C) once more I get a different message: executing Oz code block... Org-babel: executing Oz expression Create OPI socket for evaluating expressions org-babel-insert-result: Wrong type argument: markerp, nil If I do it a third time then all works fine, i. e. executing the code block #+begin_src oz :results value 39 + 3 #+end_src results in insertion of #+RESULTS: : 42 into the org file. It seems a bit strange for me, but it is usable. Johannes
