How to decalare a new datasource in jboss as 7

Question

As I know with the new JBoss application server, there is 2 ways to declare datasources :

• Adding the datasource to the standalone.xml file
• Adding the datasource under application.ear/META-INF/datasource-ds.xml

My questions are :

1. what is the best way to declare datasources in term of (best practices/maintainability,.. )
2. If I use the 2sd way, does my datasource shared between all ear deployed?

Thanks in advance

Answer 1

The best way (and safest) to add a datasource is by means of adding at first a new module for the JDBC driver, then creating a datasource which uses the JDBC driver as a module. See here how to create a datasource with JBoss AS 7
Deploying a datasource along with your application should be used for test purposes only as it is won't be manageable from the AS 7 Console/CLI this way.
