Our website provided a free download of Obba 6.2.2 for Mac. This Mac application was originally designed by Spacelike. The program is included in Business Tools.
From the developer:
Obba provides a bridge between spreadsheets and Java classes. With Obba, you can use spreadsheets as GUIs (Graphical User Interfaces) for your Java libraries. Loading of arbitrary jar or class files at runtime through a spreadsheet function. Instantiation of Java objects, storing the object reference under a given object label.
