JBoss 4.x: How to retrieve a Datasource from a standalone Ja

[afl]

I know that this is the 10.000.000 time this question is asked:

How can I retrieve a DataSource from a piece of Java code that does not run inside JBoss? Just a few lines of sample code would be sufficient!

Please do not let me die stupid!

Regards,
Andreas
