如何快速地部属Struts2
开发工具－Eclipse Struts2.0
从新建Web/Dynamic Web Project开始
不说简单的了，只说几点要特别注意的
1.应用Struts2
将xwork-2.0.4.jar、commons-logging-1.0.4.jar、freemarker-2.3.8.jar、ognl-2.6.11.jar、struts2-core-2.0.11.jar这几个包copy到web程序的lib下。其它的不要。否则发布的时候会报：Unable to load bean: type:com.opensymphony.xwork2.ObjectFactory class:org.apache.struts2.spring.StrutsSpringObjectFactory - bean错误
原因是：If any Struts 2 Plugins are included, then other JARs may be needed too. For example, the optional Spring Plugin requires the Spring JARs to be present.
2.部属

<?
xml version="1.0" encoding="ISO-8859-1"
?>

3.Action Class
继承ActionSupport（com.opensymphony.xwork2.ActionSupport）
实现execute
返回ERROR，INPUT，LOGIN，NONE，SUCCESS之一
