第三方包

通过测试。一个简单任务只需要以下几个包：commons-beanutils.jar、commons-collections.jar、commons-logging.jar、commons-digester.jar、quartz.jar即可

名称	必须/备注	网址
activation.jar	主要是 JavaMail 要用到	http://java.sun.com/products/javabeans/glasgow/jaf.html
commons-beanutils.jar	是	http://jakarta.apache.org/commons/beanutils
commons-collections.jar	是	http://jakarta.apache.org/commons/collections
commons-dbcp-1.1.jar	是，假如用到数据库作为作业存储	http://jakarta.apache.org/commons/dbcp
commons-digester.jar	是	假如你使用了某些插件，就需要它
commons-logging.jar	是	http://jakarta.apache.org/commons/logging/
commons-pool-1.1.jar		http://jakarta.apache.org/commons/pool/
javamail.jar	发送 e-mail 用	http://java.sun.com/products/javamail/
