dotnetfromjava is a Java software API to provide access to the .NET APIs without writing native code. From the Java developers' point of view, the main Java object that makes .NET API calls is NetObject. From the .NET developers' point of view, NetObject is the RuntimeType of a .NET (Object) Instance. NetObject is the root object of the dotnetfromjava library and can invoke (nearly) any member via reflection of (nearly) any .NET Object.
ivata masks is a library of routines developed in Java/JSP/Struts that automatically create masks and lists based on Java reflection and settings specified in XML, which saves a huge amount of time. Rather than developing input screens and lists for each value object class, you need to define just two screens - one for lists, the other for input masks. An XML file defines which fields should be displayed or filtered out in each, and the library automatically interrogates the value object classes to discover which fields are available for display. Struts messages automate the field labels based on the field name as a key.
Jeff's Java Scanf Library is an implementation of the C-Runtime scanf, fscanf, and sscanf functions. The syntax of format strings is very similar (%*s, %3d, etc.) to that of the standard C implementation of scanf. Instead of taking wrapper objects, all scanf functions return an Object, whose types can be inferred from the format string.
