I'd like to clarify some of the requirements around resource annotations.
There's two kinds of resource annotations that can be applied to a class:
1. Resource reference annotations such as @Resource. This is probably
rarely used (as opposed to injection), but can be useful in cases where
dynamic lookup of the resource is required.
@Resource(name = "myDS", lookup = "java:app/application-database")
public class Something {
public void someMethod() {
...
InitialContext ic = new InitialContext();
DataSource ds = (DataSource)ic.lookup("myDS");
}
}
2. Resource definition annotations such as @DataSourceDefinition.
@DataSourceDefinition(
name = "java:app/applicaiton-database",
className="org.apache.derby.jdbc.ClientDataSource",
url="jdbc:derby://localhost:1527/myDB;user=bill",
databaseName="testDB",
serverName="luckydog"
)
public class SomeOtherClass {
...
}
I have some questions that I'd like each of you to answer:
For Java EE implementors:
In your implementation, what classes may contain each of these
types of annotations?
A. A limited set of container-managed classes.
B. Any class that also supports injection (table EE-5.1).
C. Any class in the application package (ear/war/jar file).
D. Any class in the application package or referenced as an
external library.
E. Other. (Explain)
For Java EE developers:
What classes do you expect may contain each of these types of annotations?
A. A limited set of container-managed classes.
B. Any class that also supports injection (table EE-5.1).
C. Any class in the application package (ear/war/jar file).
D. Any class in the application package or referenced as an
external library.
E. Other. (Explain)
For everyone:
What classes do you think the Java EE 7 spec requires must be able
to contain each of these types of annotations?
A. A limited set of container-managed classes.
B. Any class that also supports injection (table EE-5.1).
C. Any class in the application package (ear/war/jar file).
D. Any class in the application package or referenced as an
external library.
E. Other. (Explain)
F. I don't know.
Thanks.
