Can you use Charged Headlong with a javelin?

[LoveMeAndDespair]

1. Assume I have initiative for this question.
2. I play Charged Headlong
3. It says "Game Text: If you have initiative, discard a possession to play a possession from your discard pile."
4. I discard a javelin (Riddermark Javelin or Rohirrim Javelin - Archery: Discard this possession to make the fellowship archery total +1.)
5. I play some other possession from my discard pile
6. Has +1 been added to the fellowship archery total?
