This module generates an XML scheme file for the MINA Spring configuration namespace. This XSD is referenced by Spring configuration files using MINA components to have a much less verbose configuration. When used with the XBean application context loader the same old Spring ApplictionContext is generated from this more intuitive and terse configuration file.

There is a newer version: 2.2.4
