安装好mysql后，在开发JSP页面使用mysql时，出现了如下问题. java.sql.SQLException: Communication failure during handshake. Is there a server running on localhost:3306? 我的mysql是mysql-5.0.22，JDBC驱动是mysql-2.0.4.jar， 网上找个半天，发现是版本的问题。JDBC驱动器的版本和mysql的版本不匹配， 结果把JDBC的驱动改为mysql-connector-java-5.0.8-bin.jar， 就okay了。 另外在用新的驱动器的时侯要把老的给删掉。
