JRuby Online Books

Hi, Are there any good online JRuby e-books? Thanks

From stackoverflow

• I've had good success with O'reilly books. They offer a 'cookbook' which I think is the best way to learn JRuby - learn from example. It's available in print or as an e-book.

• You can see some tutorials at http://jruby.codehaus.org/Tutorials, but why are you looking for books and tutorials relating to JRuby specifically?

  For the most part, JRuby is compatible with Ruby and most Ruby books will also be applicable to JRuby. Unless there's something specific that you're trying to do that you can't figure out?

  rjh : JRuby on rails, Spring/Hibernate/JNDI/JMS integration, calling Java from Ruby and vice-versa. The tutorials are a little sparse right now, so I don't blame him.

  Lennie : Calling Java from Ruby.

• According to Ola Bini. Most of what applies to Ruby may apply to JRuby it self.

  Even Matz somehow acknowledges that ( arouns min 28 )

  So, most Ruby books should do for JRuby

  Lennie : Calling Java from Ruby.

  OscarRyz : That's just another library. Take a look at the Ola Bini video above. It displays some samples on how to do the invocation.
