[jboss-as7-dev] Special content overlays (Was: Re: Oracle datasource missing dependencies)

The problem is the driver itself.
Oracle 10.2 jdbc driver is type 3 driver and it can't be loaded by
java.util.ServiceLoader using the META-INF/services directory in the jar.
And it's the only way we are supporting jdbc as module or deployment.
IOW we are just supporting type 4 driver.
Use Oracle 11g driver, I've tested it and it's working.
Exactly right. We do need an easier way to support JDBC 3 drivers
though. Once https://issues.jboss.org/browse/AS7-431 is merged we
should have more options though.
First option would be to deploy a neighboring content root which
includes the requisite META-INF/services file alongside the JDBC driver
JAR like this:
<deployment name="my-driver.jar">
<fs-archive path="deployments/my-driver.jar"
relative-to="jboss.server.deploy.dir"/>
<fs-exploded path="user-stuff/my-driver-overlay"
relative-to="jboss.server.base.dir"/>
</deployment>
Where user-stuff/my-driver-overlay contains the
META-INF/services/java.sql.Driver file.
Or, we could introduce a new content type just for services:
<deployment name="my-driver.jar">
<fs-archive path="deployments/my-driver.jar"
relative-to="jboss.server.deploy.dir"/>
<service type="java.sql.Driver">
<class name="com.foo.blah.SomeDriver"/>
</service>
</deployment>
Granted opens a door to a whole new concept: including deployment
description in the management model.
