Obba provides a bridge from spreadsheets to Java classes. With Obba, you can easily build spreadsheet GUIs (Excel or OpenOffice) to Java code.
Here are some key features of "Obba":
· Loading of arbitrary jar or class files at runtime through an spreadsheet function.
· Instantiation of Java objects, storing the object reference under a given object label.
· Invocation of methods on objects referenced by their object handle, storing the handle to the result under a given object label.
· Asynchronous method invocation and tools for synchronization, turning your spreadsheet into a multi-threaded calculation tool.
· Allows arbitrary number of arguments for constructors or methods (avoids the limitation of the number of arguments for Excel worksheet functions).
· Serialization and de-serialization (save Serializable objects to a file, restore them any time later).
· Obba is able to provide all this through spreadsheet functions, without any additional line of code (no additional Java code needed, no VBA needed).
· OpenOffice 3.0
· Java 1.5 or later
· 30 days trial
