Obba 1.8.25

Obba 1.8.25 is a useful too which provides a bridge from spreadsheets to Java classes. With Obba, you can easily build spreadsheet GUIs (Excel or OpenOffice) to Java code.

Major Features:

1. Loading of arbitrary jar or class files at runtime through an spreadsheet function.
2. Instantiation of Java objects, storing the object reference under a given object label.
3. Invocation of methods on objects referenced by their object handle, storing the handle to the result under a given object label.
4. Asynchronous method invocation and tools for synchronization, turning your spreadsheet into a multi-threaded calculation tool.
5. Allows arbitrary number of arguments for constructors or methods (avoids the limitation of the number of arguments for Excel worksheet functions).
6. Serialization and de-serialization (save Serializable objects to a file, restore them any time later).
7. All this though spreadsheet functions, without any additional line of code (no VBA needed, no additional Java code needed).
