我一直在尝试为 Jetty 配置 c3p0 db 连接池，但我不断收到 ClassNotFoundException：

我是 Jetty 的新手，我希望最终让 phpMyAdmin 和 WordPress 通过 Quercus 和 JDBC 连接在其上运行。这是我的 WEB-INF 目录中的 web.xml 和 jetty-web.xml 文件。
jetty-web.xml：

我猜我丢失了一些罐子之类的东西。目前我已将以下 jar 放在 WEB-INF/lib 目录中：
c3p0-0.9.1.2.jar
commons-dbcp-1.4.jar
commons-pool-1.5.4.jar
mysql-connector-java-5.1.12-bin.jar
我也尝试将这些 jar 放在 JETTY-HOME/lib/ext 中，但无济于事......请有人告诉我我的配置有什么问题。我厌倦了挖掘 Jetty 的蹩脚文档。
