We study the finite temperature phase transition in 2+1 dimensional compactQED and its dual theory: Josephson junction. Duality of these theories at zerotemperature was established long time ago by Hosotani. Phase transition incompact QED is well studied and we employ the `duality' to study thesuperconductivity phase transition in a Josephson junction. For a thickjunction we obtain a critical temperature in terms of the geometricalproperties of the junction.Comment: 9 pages, discussion added about the role of the solitons. To appear in JHE
