How to Get Service Without @Inject annotation

Hi..

Could anyone give me an example how to get service bean, without using
@Inject annotation, in page class?
Is it using ObjectLocator? What built-in service to inject, in order to use
ObjectLocator?

I can use this when using tapestry-spring and spring ioc:
@Inject
private ApplicationContext springContext;
and use this statement to get bean:
entityManager = springContext.getBean(beanNames[0]);

How to do the same thing using tapestry-ioc?

Thanks..

Best regards,
Yohan

Thank you very much for your help.
I use the registry from ServletContext.

I'm using this code:
@Inject
private Context context;

and use this statement to get bean:
Registry registry = (Registry)
context.getAttribute(TapestryFilter.REGISTRY_CONTEXT_NAME);
entityManager = registry.getService(clazz);


Thanks..

Injecting ObjectLocator into a page or component class is not supported. You
need to provide a wrapper service, which uses ObjectLocator. Then inject it
into your page and retrieve your services.

Alternatively you can retrieve the Registry from ServletContext. Check this
out.
