Hi Oliver:
Thank you for clarifying. Incidentally, if you go to the Commons Configuration
home page under Documentation, click 2.1.1 > User’s Guide > Declaring and
Creating Beans > An Example or click
http://commons.apache.org/proper/commons-configuration/userguide/howto_beans.html#An_Example.
The Java code example uses the dot notation:
BeanDeclaration decl = new XMLBeanDeclaration(config,
“gui.windowManager”);
I’d recommend adding a note to the documentation that states the default
expression engine is being used in the example. I think I probably cut and
paste an example that was using the XML path expression engine instead.
Thanks again,
John
