From Trisha (SVQJUG mailing list):
O’Reilly are giving away a free eBook on Modern Java EE Design Patterns. The author, Markus Eisele, is a Java Champion and very active in the Java community. I know quite a few people in this group are working with Java EE, and may be interested to see how it lends itself to modern architectures like microservices.
The book can be downloaded here: http://oreil.ly/1QZKbBn
