Ok, thanks for the suggestion.  I'll re-word it.  And of course, I'll need to add an explanation of outjection and Seam contexts.

Another question: imagine a very simple component like this:

@Name("bob") public class Bob {
  public String getHello() { return "Hi, I'm Bob!"; }
}

Would you really say that this is outjected?  Perhaps you could, because the Seam loader is outjecting it when the JAR file is scanned?  Or is there some other word?  I would almost say, inserted into the context.

The reason I'm making a distinction here is because to me, outject implies @Out, while all the other ways of putting something into Seam context maybe should use some other word?

I only ever say something is outjected if it's set into the context using @Out or @Factory, but in general I prefer to use something like stored in the context or aliased from the context.

what about @DataModel?  that outjects as well...

That too :)

This is really confusing....

@Unwrap is for simple cases where a component needs to be injected into a context, and the class that does the managing doesn't need to be accessible. You'll see what that means when we compare @Unwrap with @Factory.

We'll create a POJO using @Unwrap to inject a simple component. @Unwrap is suited to simple cases. This particularly simple POJO will first inject a string that gives the current time

I would think every word here should really be outject.  @Out is outject and Unwrap is similar to Out, is it not, or am I really confused.  I thought Out took a POJO variable and placed it into context. Unwrap takes not the variable but the return value and places that in the context, so should not this be worded outject instead of inject.

This part really is confusing...

component needs to be injected into a context

Considering variables are only ever outjected into a contect.  They are never injected into a context

Well, that is my opinion.

@Unwrap doesn't place anything into a context, read what I wrote again :p

This whole article sounds like it was written from the reference of a context, but I thought @Out and outjected and @In and injected where from the reference of the POJO.  ie. you outject from a pojo which puts the outjected thing IN the context.  you inject to a pojo which gets the injected thing FROM the context.  Am I incorrect or are all the terms accidentally reversed?  Otherwise, I think it would be a pretty good article, though I personally am still confused between using @DataModel and @Out and such with @Factory myself.  I wish this article had more on DataModel with Factory.  We keep getting something wrong and resulted in a hack in our pages for now until we understand this better.

The difference between @Factory and @Unwrap is that @Factory creates two Seam components

Technically @Factory does not create two seam components, there is only one seam component (the manager with the @Factory annotation). The value that is outjected is not a component, just a value in a context.

Thank you for your article.

I've just finished one myself to clarify differences between @Out and @Factory :

Who’s @In ? who’s @Out ? Clarification on Seam bijection (part 1)

I think it can complete your article on @Out and @Factory usages
