java action 路径问题

StringBuilder path = new StringBuilder(request.getScheme());
  path.append("://").append(request.getServerName());
  path.append(":").append(request.getServerPort()).append(request.getContextPath());
  System.out.println("***********path:" + path);
  System.out.println(request.getRealPath("./"));
  System.out.println(request.getContentType());
  System.out.println("method:" + request.getMethod());
  System.out.println("pathInfo:" + request.getPathInfo());
  System.out.println("PathTranslated:" + request.getPathTranslated());
  System.out.println("getProtocol:" + request.getProtocol());
  System.out.println("getQueryString:" + request.getQueryString());
  System.out.println("RequestURI:" + request.getRequestURI());
  System.out.println("getServletPath:" + request.getServletPath());
结果：
***********path:http://localhost:8080/boe-portal
C:\Program Files\Tomcat 6.0\webapps\boe-portal\.
application/x-www-form-urlencoded
method:POST
pathInfo:null
PathTranslated:null
getProtocol:HTTP/1.1
getQueryString:null
RequestURI:/boe-portal/mydocument/sendMail.action
getServletPath:/mydocument/sendMail.action
