IBM Rational Business Developer with EGL Book

I really wanted to like this book, as I'm a person who believes you can avoid mistakes yourself by learning from the mistakes of others. Unfortunately, after going through about 20% of this, I realized that it was I who had made this mistake here, so I decided to move on to something else.

Don't get me wrong... There are some good lessons here; I simply found an increasing level of diminishing return with each page and didn't feel like putting so much effort in for something with such little application to my situation.
