A famous friend of mine Bruno , is leading a development here at Summa Technologies do Brasil.
He asked to me how easy or hard would be create a new Editor special for Janino in NetBeans, this editor should have sintax highlight, code-completion and so on, cause his team was in troubles to edit and to turn it fast and easy to edit.
After a couple of minutes and a good answer on NB-DEV-LIST EVERYTHING is ready to use.

Now my friends at Summa are happy with opportunity of to edit and create with a real productivity for Janino files using NetBeans.
