Hi Adam, Are you tried the security library PAC4J? (http://www.pac4j.org/) I think it plays very well with JavaEE. Thanks!

Mr. Bien, can you please explain about entity manager and transactions.
I.e I have 2 crud services(stateless session beans) each has an entitymanager
ejected and first service has also a second service ejected via @ejb. The
question is, if I have a method in first service which uses its em and calls a
method in second service which in turn also uses its em, do the 2 em's share
the same db connection? what If we have lots of entities with corresponding
crud services each with its own em, what is the best practises regarding
implementation of access to em?

Hi,

I have a question about how to properly organize the code in a microservices project, both when it comes to the different services themselves and the module and package structure within earch service.
One repo or one per service? One module per service or several? And then we have package structure, which I am not sure what would be best practice to use. After some googling I can't seem to find any really good answers, but surely some ways must work much better than others!

Jonas

Hi Adam,
Two questions:

1. What is your perception on the adoption of using gradle in the industry today? Do you see it replacing maven in the long run?
2. JavaEE enterprise applications often need to come with resources like sql-scripts and customizing/config-scripts for application-servers: What is your recommendation on packaging these resources to later on making them available to the parties that need them (sql to DBA, WS-customizing-scripts to Websphere Admin). What approaches have you seen to work best? Package within the jar/war and extract later for those other parties; or package those resources in seperate rar-archives maybe?

Regards,
Daniel

Hi Adam,

my client, a small company, is very concered about oracles aggressively pursuing java licensing fee. What do you recommend? Is OpenJDK a solution? What are the difference between Oracle JDK und OpenJDK?
