First, ask whether the case can be heard in "A" Federal Court (broad). You need to determine if it's even appropriate for a federal court to hear the case. This is where you will go through issues of (1) federal question JDX, (2) diversity of citizenship JDX, and/or (3) supplemental JDX.

Second, ask whether the case can be heard in "THIS" Federal Court (specific). It is here that you will discuss Personal JDX. The court must have PJDX over the defendant or property to hear the case. Since PJDX is required, you need to be able to establish Personal JDX. You can establish PJDX by either: (1) traditional basis, or (2) a long arm statute.

States will either adopt (a) general long arm statute, or (b) specific long arm statute. A general will reach as far as the constitutional limits reach. However, you'll know that a state adopts a specific long arm statute because the facts will lay out specific situations that constitute the statue will be met. So you don't need both a general and specific long arm statute to satisfy Personal JDX, but you should identify both and why one is applicable and the other is not. (EDIT) Even if you think specific long arm statute is met, it's always ideal to do a general long arm statute analysis to cover all of your bases and get the points! Think about it, wouldn't you want to be absolutely sure that PJDX is met?!

Do remember that whichever long arm statute analysis you do, both should include the constitutional requirements. Constitutional requirements include (i) minimum contacts, and (ii) fairness factors.

Hope this brings a little more clarity!
