My technology literacy is not very high - therefore, my question - Currently a component of aa architectual system is implemented using Webserver APIs from both Microsoft and Netscape (ISAPI and NSAPI) and they are migrating to J2EE. Could you please explain the differences, including the benefits and disadvantages of migration to J2EE. Also how long cumbersome is this process? Finally, what do you need to do in order to roll-out the new architecture to your existing client base? How difficult is this? Finally, in layman terms is it possible to explain what J2EE does?

I cannot explain much about NSAPI(Netscape Server API) at the moment. But can explain something about ISAPI(Internet Server API) and J2EE(Java 2 Enterprise Edition) differences, etc.
Win32 API has extensions for writing DLL interfaces with Microsoft web servers. It is good if the server platform is Microsoft e.g IIS on NT. You would invoke a ISAPI program from browser as http://www.someserver.com/some.dll?args
I have a feeling that NSAPI concept should be similar. NSAPI is used to write programs to interface with Netscape servers.
J2EE(Java 2 Enterprise Edition) is a technology entirely different from Microsoft ISAPI and is from Sun. It is used to write Java based client/server programs including Java Servlets, Java Server pages and certain other java based server side components. J2EE provides a solid infrastructure to create distributed, client server applications in Java which can easily be web applications also. I feel Java's main strength is supporting a server platform particular for web. If ur

I feel Java's main strength is supporting a server platform particular for web. If ur thinking to migrate to J2EE from ISAPI, its a very good choice. Writing ISAPI programs also involves much windows programming. But its very good, if Microsoft server is ur choice and u have good expertise in windows programming.

Hope I helped..
