A typical approach is to pass a DataSource up to the model (hence the
DataSource manager). The model then just uses whatever DataSource it is
given to snag a connection.
I recently came up with a ConnectionAdaptor that can be used by the
model directly. The servlet instantiates the adaptor an

Hi Donald,
The approach I have used is to define a base exception that contains a map
of error messages. Have your business exceptions extend this. In the struts

I totally agree with this statement, but I've been having real problems
keeping the Model from knowing it's a webapp and still being able to
properly share a database connection. I'm still a beginner to java

I generally use the second approach. The whole ResourceBundle concept is
part of the Java platform and not Struts specific. So I have I my
business classes return message tokens and any pertinent replacement
parameters. The parameters do not usually need to be translated so this

I would agree that your model should not be manipulating ActionError(s).
If your requirement is that you MUST send multiple errors back from the
model then perhaps a custom exception (with a list of other exception,
errors string, or keys to i18n, internal to it), that you can pick apart in
