我用的是MyEclipse,原文件如下(Register.jsp):
<%@ page language= "java " import= "java.util.* " pageEncoding= "gbk "%>
<%@ taglib uri= "WEB-INF/struts-html.tld " prefix= "html "%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+ ":// "+request.getServerName()+ ": "+request.getServerPort()+path+ "/ ";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN ">
<html>
<head>
<base href= " <%=basePath%> ">
<title> My JSP 'index.jsp ' starting page </title>
<meta http-equiv= "pragma " content= "no-cache ">
<meta http-equiv= "cache-control " content= "no-cache ">
<meta http-equiv= "expires " content= "0 ">
<meta http-equiv= "keywords " content= "keyword1,keyword2,keyword3 ">
<meta http-equiv= "description " content= "This is my page ">
<!--
<link rel= "stylesheet " type= "text/css " href= "styles.css ">
-->
</head>
<body>
<html:form action= "Registor.do ">
rUsername <html:form type= "text " property= "username "/> <br>

re-enter password <html:form type= "password " property= "password1 "/> <br>
<html:form type= "submit " value= "Register "/>
