Suhail, There is a Java implementation of the Trader Object Service at http://www.intellisoft.com/~mark called Jtrader. It may be a starting point for development of a C++-based service if that's what is needed. Jtrader is said to work with VisiBroker 3.0 or OmniBroker v2., a different free ORB. He says it may be portable to other ORBs. Kim Gillies kgillies@gemini.edu
