VaGen and CoolGen both are two different interface layer programs used to expose mainframe to front end Java application. As usual, Java can not understand mainframe Cobol logic. It needs translator. These two will act as translators to convert logic into Java understandable syntax.
This enables companies to transform their OS390 and Unix applications to large-scale Web solutions that leverage proven technology. Check here the architecture
Organizations do not have to have applications re-written as the solution ensures that the functionally of the application in COBOL/CICS is identical to that of the applications when they ran in the original VAGen or CSP environments.
