You still need to create a custom resource [1] for GlassFish to be aware
of this resource. The context.xml definition [2] is equivalent to the
web.xml definition [3] but still needs the custom resource to be created
for the server.
[1] asadmin create-custom-resource --restype
javax.naming.spi.ObjectFactory --factoryclass
com.foo.bar.StringObjectFactory bar
For example,
[2]
<Context ...>
...
<Resource name="jdbc/EmployeeDB" auth="Container"
type="javax.sql.DataSource"
description="Employees Database for HR Applications"/>
...
</Context>
[3]
<resource-ref>
<description>Employees Database for HR Applications</description>
<res-ref-name>jdbc/EmployeeDB</res-ref-name>
<res-ref-type>javax.sql.DataSource</res-ref-type>
<res-auth>Container</res-auth>
</resource-ref>
