Important
JDemetra+ v3 is under active development and improvement, while v2 is in maintenance mode. The v3 has all the features of v2, and it can use v2 workspaces. However, note that the opposite is not true: once a v2 workspace is modified by v3, v2 cannot read it anymore. JDemetra+ v2 will reach its end of life in December 2026, which coincides with the end of Java 8's official support.
JWSACruncher is the Java implementation of the .NET application "WSACruncher". It is a console tool that re-estimates all the multi-processing defined in a workspace. The workspace may have been generated by means of Demetra+ (.NET), of JDemetra+ (Java) or by any user tool.
