Re: AppModule: using injected service in ContributeWebSecurityManager
Hi,
I created a JNDI object provider to directly inject JNDI resources into
managed services :
public class JNDIObjectProvider implements ObjectProvider {
@Override
public T provide(Class objectType, AnnotationProvider
annotationProvider, ObjectLocator locator) {
JNDIResource annotation =
annotationProvider.getAnnotation(JNDIResource.class);
if (annotation == null) {
return null;
}
String name = annotation.value();
try {
Context ctx = new InitialContext(); T resource =
(T) ctx.lookup(name);
return resource;
} catch (NamingException e) {
throw new RuntimeException("JNDI lookup failed for name: " +
name, e);
}
}
}
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.FIELD)
public @interface JNDIResource {
String value();
}
Used in a service :
@Inject @JNDIResource("java:comp/env/jdbc/myDataSource")
private DataSource dataSource;
Hope it can help

Re: AppModule: using injected service in ContributeWebSecurityManager
Thanks.
It works.
I created
public static DataSource buildMyDataSource() {
// ... implemenation.
}
then inject the code using @Local @Service("myDataSource") DataSource
dataSource like you suggested.

Re: AppModule: using injected service in ContributeWebSecurityManager
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 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.

AppModule: using injected service in ContributeWebSecurityManager
Hi i have the following problem. I have set the following code.
public void contributeWebSecurityManager(
final Configuration configuration
//, @InjectService("myDataSource")final DataSource
dataSource
) {
final JdbcRealm realm = new JdbcSaltedRealm();
realm.setDataSource(getJndiDataSource());
// realm.setDataSource(dataSource); -- does not work
realm.setAuthenticationQuery(AppModule.AUTHENTICATION_QUERY);
realm.setUserRolesQuery(AppModule.USER_ROLES_QUERY);
realm.setPermissionsQuery(AppModule.PERMISSION_QUERY);
realm.setPermissionsLookupEnabled(true);
realm.setCredentialsMatcher(this.credentialsMatcher);
configuration.add(realm);
}
In the same AppModule class I have this
public static void bind(final ServiceBinder binder) {
binder.bind(DataSource.class,
AppModule.getJndiDataSource().getClass())
.withId("blog.dataSource");
}
When i run my app it seems the datasource is not injected. How am I able to
inject the datasource binded into ContributeWebSecurityManager.
This is error i am getting when using service injection instead of just
manually getting the datasource.
