关于struts表单提交的问题..

刚开始学struts好郁闷,还感觉不到它的好处..我用的是MyEclipse自带的struts1.3版本..

做一个发送Email的页面

在Action的execute方法里面验证成功后,我怎么使用Email发送的那个Servlet呢?还是直接在execute里面直接Email发送的代码..

如果直接在execute里面写代码,又有一个问题...Servlet里面是有一个public void init(ServletConfig sc){}这个方法的,但是Action没有,没有这个初始化方法,我不能获得工程的绝对目录吧..我以前是定义一个ServletContext sc变量,然后在init里面

this.sc = sc.getServletContext();

附件上传的时候用sc.getRealPath("/");就能获得到工程的路径!

发送应该在action里面直接调用发送的系统支持类。比如
MyEmail.send(....);
然后按照发送的结果转到不同的处理结果页面

怎么获得工程的绝对路径呢?还请大家帮我看一下..谢谢.
