Hi!
I'm pretty sure your dataSource is being injected, otherwise you'd
receive a different error and not an NPE.
This looks wrong to me:
binder.bind(DataSource.class,
AppModule.getJndiDataSource().getClass()).withId("blog.dataSource");
Specifically the:
AppModule.getJndiDataSource().getClass()
Do you not know what the class is at compile time? Rather than
binding, you may want a use Builder method.
Also, the binding gives an ID of "blog.dataSource" but you're
injecting "myDataSource"...?
As an aside, I usually inject services in my Module with this:
public void contributeWebSecurityManager(
final Configuration<Realm> configuration
@Local DataSource dataSource) {
...
}
No need for @InjectService.
The @Local tells T5-IoC to look for a service defined in *that* module
class. Because DataSource is a popular interface, it could be defined
in other modules. The annotation helps to dis-ambiguate between them.
