Java Weekly #6: Micro Services, CDI 2.0, NoEstimates and more...

Java

After using Scala for some days and switching back to Java, Lucas Eder started to miss some features of the Scala syntax. He wrote a blog post about The 10 Most Annoying Things Coming Back to Java After Some Days of Scala. 

Java EE

Roberto Cortez wrote a great tutorial on how to deploy Spring Batch as a Wildfly module. You should have a look, if you want to use one of the most feature rich implementations of JSR-352 with Wildfly.

Monitoring the O/R mapper becomes an important task, if you need to analyze performance issues of a Java EE application. Therefore Hibernate provides its Statistics Interface which exposes several statistics related to sessions, entites, queries and more. If you like to learn how to activate these statistics and how you can access them, have a look at Hibernate Statistics with Hawtio and Jolokia by Markus Eisele.

The proposal for the CDI 2.0 specification was accepted. If you like to learn more about the main goals of the specification, have a look at the CDI specification website where the team explains what’s new in the CDI 2.0 JSR.

There are lots of discussions about Micro Services at the moment and the number of available frameworks is constantly growing. One of them is Fabric8 which provides an application server agnostic way to implement and manage Micro Services. James Strachan provides a short tutorial and video on how to use Fabric8 to implement Micro Services.

This and That

Customers often ask for a first estimation for complex project but the creation of it is always an issue. Pietro Polsinelli and Massimo Iacolare suggest in their article From #NoEstimates to #YesPrototypes to provide a prototype and focus on the dialog with the customer instead of creating estimations. This allows both parties to focus on the required learning process and to avoid high economical risks.

Done!

That were the most interesting Java related resources I found this week. I hope you find them useful.

If you think I missed something, please post a comment with the link. I will check it and include it in the next issue of Java Weekly.
