How to Resolve the 'No Method Found Annotated with @Named#value' Error?

What does the error 'No method found annotated with @Named#value' mean in Java EE?

@Named
public class MyService {
    public String getServiceName() {
        return "My Service";
    }
}

The error 'No method found annotated with @Named#value' typically indicates that your code is attempting to access a bean or method that is not properly defined or accessible in the context it is being called from. This issue commonly arises in Java EE or CDI (Contexts and Dependency Injection) environments.

@Named("myService")
public class MyService {
    public String getServiceName() {
        return "My Service";
    }
}
// Accessing the bean
@Inject
@Named("myService")
private MyService myService;

Causes

• The method or bean you are trying to access is not correctly annotated with @Named.
• There may be a naming conflict or typo in the method/function name used in the @Named annotation.
• The class containing the method is not in the correct package or is not being scanned by the CDI container.
• Dependencies are not properly configured, leading to the bean not being recognized.

Solutions

• Ensure that all classes and methods you want to use with @Named are correctly annotated.
• Double-check the naming in your calls to make sure they match the definitions exactly, including case sensitivity.
• Verify the configuration of your CDI container to ensure it scans the appropriate package containing your beans.
• Review your project's dependencies and ensure that you are using compatible versions of the required libraries.

Mistake: Incorrect casing or spelling in the '@Named' annotation value.

Solution: Ensure that the exact name specified in the '@Named' annotation is used while injecting or referencing the bean.

Mistake: The Java class is placed in a non-scanned package, failing to register within the application's context.

Solution: Check the application configuration to confirm that your package structure is included for CDI scanning.
