I am taking over management and development of a website developed in Java using Hibernate and Postgres, running on Apache/Tomcat.  I am an experienced Java developer, and have experience in Ruby on Rails, and am expert in Oracle SQL.  What is the best documentation for me to read?
What reading is recommended for an experienced Java/SQL Developer moving to Apache/Tomcat, Postgres, Hibernate
java;web development;hibernate;postgres;tomcat
For Hibernate, I can recommend Java Persistence with Hibernate. I found it very useful and thorough - it may be that others feel it's too dense, but if you are an SQL expert already, I don't think you will have any problem with it.
