servlet 如下：
package servlet;
import java.io.ioexception;
import java.io.printwriter;
import javax.servlet.servletexception;
import javax.servlet.http.httpservlet;
import javax.servlet.http.httpservletrequest;
import javax.servlet.http.httpservletresponse;
public class hellowservlet extends httpservlet {
public hellowservlet（) {
super（);
}
public void destroy（) {
super.destroy（); // just puts "destroy" string in log
// put your code here
}
public void dopost（httpservletrequest request, httpservletresponse response)
throws servletexception, ioexception {
response.setcontenttype（"text/html");
printwriter out = response.getwriter（);
out
.println（" <!doctype html public \"-//w3c//dtd html 4.01 transitional//en\"> ");
out.println（" <html> ");
out.println（" <head> <title> a servlet </title> </head> ");
out.println（" <body> ");
out.println（"hello world <br> ");
out.println（" </body> ");
out.println（" </html> ");
out.flush（);
out.close（);
}
public void init（) throws servletexception {
// put your code here
}
}
web.xml
<?xml version="1.0" encoding="utf-8"?>
<!doctype web-app public "-//sun microsystems, inc.//dtd web application 2.3//en" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name> hellowservlet </servlet-name>
<display-name> this is the display name of my j2ee component </display-name>
<description> this is the description of my j2ee component </description>
<servlet-class> servlet.hellowservlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> hellowservlet </servlet-name>
<url-pattern> /hellowservlet </url-pattern>
</servlet-mapping>
</web-app>
jsp 調用：
<%@ page language="java" import="java.util.*" pageencoding="big5"%>
<%
string path = request.getcontextpath（);
string basepath = request.getscheme（)+"://"+request.getservername（)+":"+request.getserverport（)+path+"/";
%>
<% string url=request.getcontextpath（) + "/helloservlet"; %>
<!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>
<form method="post" action=" <%=url%> ">
input type="submit" name="button1">
</form>
</body>
</html>
爲會麽在websphere 訪問不了servlet 出現http 404 找不到
但在apache tomcat 下就可以訪問
不知websphere 下怎樣設置才能訪問servlet? |
