BEA WebLogic was chosen to be the first Beta target for integration due to customer demand and its number one position in terms of application server market share.

"ATG's platform and applications are even more valuable to our organization now that they are being built to run on additional application servers," said Robert Brunner, Partner, Financial Services at KPMG Consulting, Germany.
