Re: [seam-dev] First cab off the rank!
Remoting now has full support for looking up qualified beans, so you can
now do cool stuff like this:
<script type="text/javascript">
function sayHello() {
var name = prompt("What is your name?");
if (name == null) return;
var callback = function(result) { alert(result); };
Seam.Component.create("org.jboss.seam.remoting.examples.helloworld.HelloAction",
"@HelloQualifier(foo = 123, bar =
String.class)").sayHello(name, callback);
}
</script>
@Retention(RUNTIME)
@Target(TYPE)
@Qualifier
public @interface HelloQualifier {
int foo();
Class bar();
}
@HelloQualifier(foo = 123, bar = String.class)
public class HelloAction {
@WebRemote
public String sayHello(String name) {
return "Hello, " + name;
}
}
If the bean is @Named then you can simply pass in the name to
Seam.Component.create() in JavaScript, otherwise you can use a
combination of bean type and qualifiers. I need to still do some work
on the API, instead of Seam.Component.create() I'm thinking
Seam.Bean.instance() instead.

Good point - isn't this simply a case though of implementing the
equals() and hashCode() methods and checking that the members are equal,
i.e. the same way that AnnotationLiteral does it?
