The Pacers also sent guard Sarunas Jasikevicius and forward Josh Powell to the Warriors, who gave up forward Ike Diogu and guard Keith McLeod.
"We feel we made a pretty significant trade for the franchise that will be good for both teams," Pacers president Larry Bird said in a statement. "We feel the players we got will make a significant difference in the franchise."
Murphy, Dunleavy and Diogu had been reduced to high-priced backups for failing to measure up to new coach Don Nelson's expectations this season, while Jackson was dogged by legal troubles and attitude problems in Indiana.
"We have acquired players who will fit in very well with our particular style of basketball," said Chris Mullin, the Warriors' executive vice president of basketball operations. "As with any trade, we also had to surrender players that we like both on and off the court. I think this transaction will be good for both teams and all of the players involved."
The deal left injury-plagued Golden State with just six healthy players on its roster for Wednesday night's game against the Los Angeles Clippers - two fewer than the NBA minimum required to avoid forfeiting a game. The Warriors were expected to sign another player to a 10-day contract and suit up one of their injured players to avoid the forfeit.
Harrington - one of the Warriors' top targets in free agency last season - averaged 15.9 points and 6.3 rebounds this season, second on the team in both categories to Jermaine O'Neal. Jackson has scored 14.1 points per game, but embarrassed the club with an early-season fight at a strip club and a spat with coach Rick Carlisle in December.
Murphy, a former Notre Dame star who has been bothered by injuries this season, is averaging 8.9 points and 6.0 rebounds - both his lowest totals since his rookie year. Dunleavy has scored 11.4 points in another disappointing season, so the deal rids the Warriors of three players who didn't fit with Nelson's ideas - including two prominent targets of his criticism this season.
Jackson, the sharp-shooting guard, has been almost nothing but trouble for the Pacers this season, beginning with a fight outside an Indianapolis strip club on Oct. 6. He is scheduled to go to trial Feb. 12 for firing a gun during the fracas.
In December, the Pacers briefly suspended Jackson for a heated exchange with Carlisle, who kicked him off the bench during a loss to Cleveland. The Warriors' last look at Jackson was impressive, however: Earlier this season, Jackson hit a 3-pointer with 1 second left in a 108-106 victory for Indiana at Golden State.
Dunleavy and Murphy lost their starting jobs to Andris Biedrins and Matt Barnes.
Dunleavy, the No. 3 overall pick from Duke in 2002, has been a huge disappointment - hurting with Warriors with everything from poor play and unimpressive athleticism to an uncaring attitude and a tendency to blame teammates for mistakes.
Even the incredibly loyal Warriors fans at Oracle Arena have booed him loudly and regularly this season.
