Questions for the November edition of the http://airhacks.io show:
- Question about ejb scheduler vs java ee batch processing. What are pros and cons when using batch processing over ejb scheduler ? Marek
- Question about multi datasource and EJB. What is the best way to deal with EJBs
which need to use a specific database for caller/user? Should I use
Interceptors? Should I use injection with request scoped? Wesley - Statement: "You forgot to say one advantage of Spring over JEE. Spring you can deploy on any container." Mauricio
- 'How do you manage deployed microservices (status, healthchecks, restarting) locally and on servers?' Tomek
- 'How do you use Docker (what setup) locally and on servers? Tomek
- Does JSF play well with JavaScript frameworks? [Edward]
- Why It Is Impossible To Automatically Handle javax.persistence.OptimisticLockException? "...I had even more finding on optimisticLockException. I had encounter this
exception and my solution was pretty straight forward which was just retry and
it works fine with my design and the data were good. The catch is, recently I added a new table which has a relationship to the row
which was throwing the optimisticLockException. I noticed that the entry in the second table was not created because of this exception. However the record data consistency was maintained because of the retry. But I loose an important
information in my related table. Does anyone have suggestion on what to do with this kind of scenario?..." [Anuj] - can you share some updates on how to do high availability JEE apps in light of
JEE7 and tackling session stored data Ahmed
About:
Yeah! Great Idea: Deploying some sort of container into another full-featured container to get 20000 lines of XML-style configuration and tons of spring-anykind.jar dependencies...
For sure: There is no(!!) advantage to bring nearly the same idea (namely the Dependency Injection) with another proprietary container and install it on top of a container that offers this idea (including other great ideas) out-of-the-box, specified (and compatibility-proofed with TCK) by a large and developer-friendly community.
Well, I've seen projects, deploying embedded-glassfish-all.jar inside a WAR into some sort of Application Servers to get all the best-of-breed libraries (jersey, tyrus, a.s.o.) in the application and wondering, why the application will not work as expected.
