我正在尝试将JRuby on Rails war部署到Tomcat6中。出于某种原因，它无法找到activerecord-jdbcmysql-adapter。我正在运行Rails 2.3.8，JRuby 1.5.5，JRuby-Rack 1.0.3。创业板打包带捆扎机，我看到它的WEB-INF /宝石/宝石目录：Tomcat无法找到JRuby war中的jdbcmysql适配器
drwxr-xr-x 3 root root 4096 2010-11-19 20:07 WEB-INF/gems/gems/activerecord-jdbcmysql-adapter-0.9.2
我丢失了一些环境变量或东西是引起Tomcat来没有找到宝石？它显示在宝石列表中，它也在适当的目录中。
我的database.yml如下所示：
production:
adapter: jdbcmysql
encoding: utf8
database: mydb
host: localhost
port: 3306
username: foo
password: somepassword
