There is undoubtedly water on the extrasolar planets we've discovered, but more than likely NOT in liquid form on the surface; most of the "hot Jupiters" are simply too close to their primary and water can only exist as vapor. Others are too far away and/or so big, water is either ice or in vapor clouds like Jupiter and the other Jovian planets. That's not to rule out that any moons of these large planets might not have liquid water on their surface.

Yes, through an analysis, Jupiter has been found to have trace amounts of water in it's inner atmosphere. Also, the moon Europa also has water on it. Mars also has some water under it's surface.
