The J2EE application server is used as a control element for a material cutting machine for plussize bras, bigger than cup size I2.
J2 is a Level 2 bra. Normal measurement goes from A to Z. Since you only have 26 letters you switch to Level 2. After Z comes A2, B2, C2, ..., J2.
EE stands for Extra Emphasis. Just a kind of push up bra to emphasize the cleavage.
A J2M application server (M=Minimizer) is more common in that business. You can imagine that a J2 endowed woman rather wants to hide her assets.
