This is the second of two articles describing how JP Morgan in London
developed an XML interface between a Web-based bond trading system and one of
its back-office systems. Part 1 (Vol. 8, issue 8) focused on parsing the XML
file; Part 2 shows how to write an NT service in PowerBuilder.
Why Use an NT Service?
JP Morgan's XML interface has to perform three core functions: Process
incoming XML messages. Watch for state changes in the database. Process
outgoing XML messages. These tasks had to be performed 24/7, without human
intervention, in a secure and reliable manner. The ideal solution was an NT
service. This could be installed on a server and configured to start as soon
as the machine booted up without the need for anyone to log on. We knew that
Microsoft had a utility, SRVANY, that would let any EXE be deployed as a
service. A bit of research showed that it would... (more)
JP Morgan in London recently used PowerBuilder to implement an XML interface
between a Web-based bond trading system and one of their back-office systems.

developed.

details of the trade would be written down and then entered into a
back-office system. The dealers, banks, and c... (more)
