问题
As mentioned in the article https://community.jboss.org/wiki/DataSourceConfigurationInAS7 JBoss 7 provides 2 main ways to configure a data source.
What is the BEST practice of configuring a data source in JBoss 7 AS ? Is it
- As a module?
- As a deployment?
(The same question has been asked in the thread https://community.jboss.org/thread/198023, but no one has provided an acceptable answer yet.)
回答1:
The guide JBoss AS7 DS configuration says the recommended way is to configure the datasource by deployment
But according to discussion on the link Jboss 7 DS configuration JBoss Community Discussion on page 54 of the guide it mentions that the recommended way to deploy JDBC driver is to use modular approach
But I personally say that the better(not the best) approach to configure JDBC driver would be to use modules because of 3 reasons
- JDBC driver will generally not change.
- Re-usability : You can use the same module across various applications and not deploy the jar along with each application, this prevents duplicacy
- Space Effective : Using the module approach lets you reduce the size of your EAR/WAR as you do not need to supply the jar with the package
Hence I would argue that the better of the two approaches is via modules

@Mukul Goel It's not necessary to include it the EAR of your application it's sufficient to put the .jar inside the deployments folder so:
no need to embed in ear no need to create a module
Jist deploy in deployments folder or via admin console
