The six-player deal completed Wednesday reshapes the rebuilding Bucks while giving Cleveland an additional scoring threat and Oklahoma City an instant fan favorite, Desmond Mason, in the first year of the franchise's move from Seattle.
In exchange for Williams -- who averaged 17.2 points per game last season in the first year of a six-year, $51.5 million contract -- the Bucks receive Damon Jones from Cleveland along with guard Luke Ridnour and forward Adrian Griffin from Oklahoma City.
Oklahoma City gets Mason from Milwaukee and former No. 1 pick Joe Smith from Cleveland.
The Cavs have long sought a scorer to take pressure off James, who led the NBA last season with a 30-point average.
James' lack of help was particularly noticeable in Cleveland's Game 7 loss to Boston in the Eastern Conference semifinals when he scored 45 of the Cavs' 92 points.

Ferry said the team let James know of the deal even though he's on the other side of the world.
"We've communicated with most of the team," Ferry said. "All these guys are very excited. They respect Mo as a player, and they're looking forward to playing with him."
Larry Hughes was supposed to be James' sidekick, but couldn't fulfill the role and was sent to Chicago last year at the trade deadline in a 10-player deal.
Cleveland also has been searching for years for a point guard, and considered trades in the past for Mike Bibby and Jason Kidd, but never made one. Williams could be that big trade, Ferry said.
"I think this is a move to be able to get a talented, young, 25-year-old point guard that can be part of the future," said Ferry, who added that restricted free agent Delonte West remains in the team's plans even with the trade.
