Modified: fortress/container project.xml
Added: fortress/container/src/impl/org/apache/avalon/fortress/util
ReflectiveConfigurator.java
Log:
Fortress-Creator that uses reflection instead of Parameterizable/Configurable
to configure a component. This allows to configure components
with forcing them to implement avalon interfaces.
