Dynamic datasource name and resource-ref to it

[simix]

Hello.

I need to specify datasource JNDI name dynamically for my enterprise application.

Can i add this datasource to resource-ref dependency ? Name of datasource  is unknown previously.

I need resource-ref because it is control shutdown order (datasource after my application).

You can use a variable name on your persistence.xml or web.xml, an example

<jta-data-source>${ks.ds}</jta-data-source>

For this to work you need

1) in the EE subsystem (Web Console -> Configuration -> EE), change the "Spec Descriptor Property Replacement" to true

2) set the property/value in the Properties view (Configuration -> System Properties)

So, while I try this recommendation, I have found more fit method for my case - using default datasource binding on the page EE -> default bindigs. Is it JavaEE compliant (specify JNDI of default datasource in container) ?

Datasource will inject with code

@Resource

private DataSource myDatasource

and shutdown order is safe

Thank you
