引用別人的話"它不是一門技術(shù),更不能把它刻錄到光盤去賣什么的..它提供的是一種思想!就想OO思想一樣!
IBM WebSphere Integration Developer, Version 6 software is Eclipse technology-based tooling designed to enable you to rapidly assemble business solutions based on a composite application development framework and using minimal programming skills.
