我正在使用http://www.eclipse.org/jetty/documentation/current/session-clustering-jdbc.html
实现jetty会话群集我的jetty-jdbc-sessions.xml文件看起来像

当我用java -jar start.jar
启动jetty时,我得到了异常

我在$ JETTY_HOME / lib目录和$ JAVA_HOME / lib目录中都有我的mysql jdbc驱动程序jar文件,所以我不确定为什么我仍然会收到错误
答案 0 :(得分:3)
将MySQL JDBC Driver jar放在$JETTY_HOME/lib/ext
目录中。
答案 1 :(得分:1)
我必须在start.init中为jetty添加--module = ext来处理来自lib / ext目录的jar。
