定时器，简单记录

定时器学习笔记，记录一下。
这里使用的jar包是：quartz-all-1.6.0 jar
使用定时器的jar时，需要引用其他的依赖包
com.springsource.org.apache.commons.beanutils-1.8.0.jar
com.springsource.org.apache.commons.collections-3.2.1.jar
com.springsource.org.apache.commons.digester-1.8.1.jar
com.springsource.org.apache.commons.logging-1.1.1.jar
jta-1.1.jar
quartz-all-1.6.0.jar
才能正常的启动。
