I am happy to announce that Reza Rahman will visit the ACGNJ Java Users Group on October 10, 2017.  He will present, " Java EE 8 and Java EE 9 - What You Need to Know " at the Scotch Plains Rescue Squad (second floor) starting at 7:30pm. The process of defining the scope for Java EE 8 was the most community opinion driven in the history of the platform.   Java EE 8 is supposed to solidly enable HTTP/2, Server-Sent Events (SSE), JSON and aligning all parts of the platform with Java SE 8.  It includes a much awaited security API overhaul, a brand new MVC API as well as a slew of critical updates to APIs like JSF, JMS, JPA, JAX-RS and CDI.  Unfortunately the road to Java EE 8 has not been smooth.  After a long and silent delay Oracle announced updated plans for Java EE 8 and Java EE 9.  The plans now include adding support for dynamic configuration, health-checks, NoSQL, fat-jars, eventual consistency, multi-tenancy, dynamic discovery and circuit breake

The April ACGNJ Java Users Group meeting featured guest speaker, Elliotte Rusty Harold .  His presentation was entitled, " Exceptions: I'm Telling You for the Last Time ." Elliotte discussed the three rules of using exceptions: Rule #1 - try blocks should be long, not short Rule #2: Checked exceptions indicate environmental problems. Runtime, i.e., unchecked exceptions indicate program errors. Rule #3 - If you can't handle it, bubble it. Harold provided his reasoning for not using exceptions.  He stated, "If we haven't learned how to use exceptions within the last 20 years, will we learn over the next 20 years?  Maybe exceptions are just too hard.  And if exceptions are too hard, then what about Java features such as lambdas and data binding?" Sun forgot to document exceptions when they were first introduced in Java 1, alpha 3.  Elliotte encouraged everyone to search for the original white papers by James Gosling, Patrick Naughton, and Bi
