This doesn??™t work in all cases, though, because Java??™s class loader semantics are a little tricky.
For example, it doesn??™t work for JDBC database drivers, and not for XML drivers either. In most
cases, things that are found by some kind of service provider interface won??™t work in this way.
However, all other classes should be fine.
APPENDIX B ?– JRUBY REFERENCE 313
Resources
This chapter will give you a long list of helpful links, and pointers to a few useful books. I??™ve
tried to categorize the books by main subject, and I hope most of the addresses are still valid
when you read this. Remember that the absolutely best resource when starting out with Ruby
is your local Ruby User Group (RUG). Many cities in both the United States and Europe have
a group that meets up once or twice a month, where members share information and help
one another with problems. You should search the Internet for the closest RUG to you; it can
be invaluable.
Ruby and Rails
These links are specifically about Ruby or Rails.
The Ruby Programming Language
http://www.ruby-lang.org
This is the main Ruby language home page. Go here first to find information about Ruby. This
home page also contains lots of pointers to other resources not covered here.
Ruby-talk Mailing List
This mailing list is the main mailing list for everything related to Ruby. It??™s a high-volume mailing
list, but you can usually get answers to questions related to Ruby here. You subscribe from
the Ruby-lang home page.
