Hello,
Yes I am just playing with some few examples.
It seems for full functionality there will have to be few of them.
1. One web service for one MSDOS program that is executed now as subprogram ,,,and is critical legacy component ran on one exactly PC
so to be executed in open environment from database stored procedure, that MSDOS program will have to be wrapped into WebService It seems
2. For upper design I am now only trying to design architecture in open source technogolgy ( Postgress + Apache + Java ) and Oracle technology ...
