Java/XML Code Integrates Financial Applications


New architecture could span all enterprises where transaction processing is critical



March 1, 2001 — 
In an unusual move that cracks open an otherwise closed industry, the German bank Dresdner Kleinwort Wasserstein has released a Java/XML infrastructure to the open-source community that integrates financial data without the need to write customized code to do so. Calling the technology OpenAdaptor, the bank released the source code towww.openadaptor.org, where it will be maintained by CollabNet Inc.

"The bank has been running a global trading system with this Java/XML architecture," said Frank Hecker, CollabNet's systems engineering manager. He said that besides the obvious financial institutions such as banks and brokerages that could benefit from the architecture, "any enterprise such as aerospace, health care, insurance and manufacturing that has large-scale transaction systems that need to be integrated" would benefit.

Bernie Mills, CollabNet's vice president of marketing, added that companies experiencing growth through mergers and acquisitions that find data spread throughout several databases in need of integration would also find the open-source architecture useful.

Hecker described OpenAdaptor as a Java/XML architecture for the rapid integration of business systems without the need for custom code to integrate them. "It was developed as a toolkit at the bank for integrating its own systems and deploying to partners it was interacting with," he said.

Mills said that because the architecture doesn't deploy actual business applications or services of the bank, bank officials decided to make the code available for open-source developers to create backbones for their own applications. Mills said, "Dresdner can't make a commercial success of this, except for the applications it puts together internally." Indeed, he said, Dresdner developers looked forward to accessing innovative code developed by open-source developers to add to their own bank systems.

"It will also increase the base of developers available to build on the code," he added.

Openadaptor.org will offer open-source developers a license to use the code for their own purposes within an enterprise-or to jointly develop new applications-as well as actual code. And, through CollabNet's (www.collabnet.com) SourceCast software, the site will also provide an issue-tracking system for defects; a source repository to obtain copies and keep them updated via subscription to an e-mail service; and discussion groups on evolution of the code and applications being written for it.
