Resource Injection Question

Hi all,

I have seen many sample codes on the internet on resource injection. The codes requests a javax.sql.DateSource to an instance field.

The above code, injects a DataSource object How does the target database,
database username, database password are specified. Is this the responsibility of the Application deployer through the deployment tools.

Thanks in advance.

thats right; in the ejb core spec it reads:

"16.3.3 Deployer�s Responsibility
The Deployer must ensure that the values of all the environment entries declared by an enterprise bean are created and/or set to meaningful values.
The Deployer can modify the values of the environment entries that have been previously set by the Bean Provider and/or Application Assembler, and must set the values of those environment entries for which no value has been specified.

The description elements provided by the Bean Provider or Application Assembler help the Deployer with this task."
