Hello & Welcome Bob!

I see at runtime we deploy on Websphere which uses IBM JDK to run the application.

However in general while developing usually everyone develops against Sun/Oracle JDK.

I would want to know what is the tradeoff here? Meaning do we get any benefit if we actually use IBM JDK at the time of application development?

Would your book give more information about internals of Websphere and how Java/JDK is used/works within Websphere?

Regards,
Ravi

Hi Ravi,
The book is written as an introduction to java and OOP. I then cover the WebSphere (and non-WebSphere - like basic Windows concepts) technologies needed to create and implement client and server based apps. No real coverage of performance (Well, I discuss the adv/disadv to precompiling JSPs and why nested if are more efficient - basics). It more like learning how to drive a car not tune it. I show how to install to WAS not how WAS works internally. Re: the JDKs. I develop against the RAD JDK but install client based apps to the Oracle JDK. I've never had a problem but I'm not using any real advanced java features. If I was going to install to WAS I would develop using the RAD/IBM JDK in case there were some differences. Hope that helps.
