java(非web应用)连接mysql数据库的时候老是报出没有找到驱动jar，但是我已经设置的环境变量了呀~？

CLASSPATH的值.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;C:\Program Files (x86)\MySQL\mysql-connector-java-5.1.18\mysql-connector-java-5.1.18\mysql-connector-java-5.1.18-bin.jar
eclipes报出的错误是
Exception in thread "main" java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
