Extensions

Jwsacruncher is an application whose capabilities can be broaden by extensions.
Technicaly, these extensions are called uber-jar and are just jar files that contains both the code and all its dependencies.

Installation

Extensions can be installed manually and are stored in a specific directory.

1. Download required extension (*-uber.jar file) and save it locally.
2. Copy the uber-jar to the lib/ext directory of jwsacruncher.

Example use

This example uses the JDemetra+ Access extension.

1. Install the desktop plugin (see demetra-access-desktop-*.nbm)
2. In JDemetra+, create a new SA multi processing
3. Open an Access file and drag&drop some time series into the multi processing window
4. Save the workspace somewhere
5. Install the cruncher extension (see demetra-access-cruncher-*-uber.jar)
6. Run jwsacruncher on the saved workspace.
   The "Refreshing data" step outputs a "processed" status message if the extension is properly installed. If the extension is absent or broken, a "failed" status message is displayed instead.
