This week's book giveaway is in the Other Open Source APIs forum. We're giving away four copies of Storm Applied and have Sean Allen, Peter Pathirana & Matthew Jankowski on-line! See this thread for details.
The objective of the Adapter design pattern is to enable "objects" to work together. Your statement of using the pattern to make two "systems" work together is a bit off key.
"Systems" and "objects" are not the same terms and cannot be used interchangeably, in my opinion.
I would have been looking for you to explain the what, why and how of what you implemented in the "project", rather than a rudimentary answer not related to the "project." Demonstrating that you might know the definition of a design pattern does not show that you have experience implementing the pattern.
