Middleware4j
Middleware4j is a file-based message transformation and routing engine developed as a companion to Commander4j. It has no dependencies on Commander4j and can be used independently for any system integration requirement.
Its primary purpose is to link systems that use incompatible data formats. It monitors directories for incoming files, transforms them using configurable XSLT stylesheets, and delivers the results to one or more output destinations in the required format — running continuously in the background as a service.
For a full explanation of how the application works, see Overview_Middleware4j.
