They would need some time to make some mistakes. To even recognize those mistakes, they’d need mentors looking over their shoulders. The brutal truth was plain—to join even the lightweight Java club, they’d have to pay a high initiation fee and learn many secret handshakes. Joining the club would take much more time than they wanted to invest. Even Java developers with experience are not immune to steep learning curves. A developer with good experience with JDBC, Java’s most basic database access API (application programming interface), would still have to work hard and long to learn alternative persistence frameworks such as Hibernate or JDO.
If you can take existing frameworks and corporate assets, a common perception is that you can always be more productive overall, even with a less-productive technology. Witness the millions of lines of COBOL and CORBA (a distributed objects technology). But if you’re at all typical, you’ve spent way more money chasing reuse than you’ve saved, and modern reuse models, which we’ll discuss in Chapter 6, Bridges, on page 92, will often let you reuse code written in other languages. JRuby and the simplified Ruby on Rails web services are two technologies that allow excellent reuse across language boundaries.
You’ve seen how you can take a more productive language and use it to your advantage. But the flip side is also true—your competition can do AT R ISK 31 A L OOK the same to you.
