Configure a DataSource in TomEE in system.properties instead of tomee.conf - apache-tomee

Question

I'm able to configure a DataSource Resource in TomEE by modifying the "conf/tomee.xml" file. However, it's sort of awkward to automate this modification, as I have to insert the DataSource definition before the "" line. I heard from a comment in a related SO posting from me that it's easier to append to the "system.properties" file.
So, I tried translating this:
<Resource id="sus2" type="DataSource">
JdbcDriver = oracle.jdbc.driver.OracleDriver
MaxActive = 10
MinIdle = 2
MaxIdle = 2
MaxWait = 10000
JdbcUrl = jdbc:oracle:thin:#${DB_HOST}:${DB_PORT}:${DB_SID}
UserName = ${DB_USER}
Password = ${DB_PASSWORD}
</Resource>
Which works, to the following:
db = new://Resource?type=DataSource
db.id = Resource/sus2
db.JdbcDriver = oracle.jdbc.driver.OracleDriver
db.MaxActive = 10
db.MinIdle = 2
db.MaxIdle = 2
db.MaxWait = 10000
db.JdbcUrl = jdbc:oracle:thin:#${DB_HOST}:${DB_PORT}:${DB_SID}
db.UserName = ${DB_USER}
db.Password = ${DB_PASSWORD}
which does not work. It fails, saying it couldn't find the "Resource/sus2" resource.

The configuration reference can be found at http://tomee.apache.org/ng/admin/configuration/resources.html
You have to understand that XML attributes becomes URI query parameters then I think it will work.
In other words:
db = new://Resource?type=DataSource
becomes
sus2 = new://Resource?type=DataSource
and your db.id doesn't do anything - I think it is logged.
In short: replace all your "db" by "sus2" and it will work
