injecting services outside default packages
Hi! I want to insert some service like this:
@Inject private MyService myService;
If I do it in default packages (base, pages, components) it just
works... but I have a class outside this packages and TapIOC does
nothing (myService is null). Some way to solution? thanks!!

When you instantiate some object directly, Tapestry-IoC cannot do any
injections on it.

As your MyBean isn't and shouldn't be a proper service, inject the
ObjectLocator service and the use its autobuild(Class type) method to
instantiate your class: MyBean bean =
objectLocator.autobuild(MyBean.class);
Why would an object in a session have a reference to a service? That's
something I don't recommend.

I think that's the problem, my bean is here
/pages
/components
/myPackage/MyBean.java
..and the problem is that I instanciate ( new MyBean() ). MyBean.java
is a class I want to have in the session... how can I instanciate it
with T5IoC? thanks in advance

It should work as long as both services (the one with the @Inject field
and the injected one) are instantiated by Tapestry IoC.
