JavaMail API的使用:
- 建置JavaMail的開發環境:
(1)下載mail.jar:至 http://java.sun.com/products/javamail/downloads/index.html 下載JavaMail 1.3.2 API(或至本站下載)
(2)下載activation.jar:至 http://java.sun.com/products/javabeans/glasgow/jaf.html 下載JAF 1.0.2(或至本站下載)
(3)解壓縮JavaMail,將mail.jar複製到到應用程式目錄下的WEB-INFO/lib目錄中即可
(4)解壓縮JAF,將activation.jar複製到到應用程式目錄下的WEB-INFO/lib目錄中即可
- 撰寫簡單輸入介面程式及寄信程式:(取自JSP 2.0技術手冊)
簡單的郵件訊息輸入介面：
<html>
<head>
<title>JavaMail.html</title>
<meta http-equiv="Content-Type" content="text/html; charset=big5">
</head>
<body>
<h2>利用JavaMail來傳送電子郵件</h2>
<form name="Form" method="post" action="JavaMail.jsp">
<p>寄信人：<input type="text" name="From" size="30" maxlength="30"></p>
<p>收信人：<input type="text" name="To" size="30" maxlength="30"></p>
<p>主題：<input type="text" name="Subject" size="30" maxlength="30"></p>
<p>內容：</p><p><textarea name="Message" cols=40 rows=5></textarea></p>
<input type="submit" value="傳送"> <input type="reset" value="清除">
</form>
</body>
</html>
信件寄出：:
<%@ page import="javax.mail.*" %> <==?#93;含在mail.jar
<%@ page import="javax.mail.internet.*" %> <==?#93;含在mail.jar
<%@ page import="javax.activation.*" %> <==?#93;含在activation.jar

<h2>利用JavaMail來傳送電子郵件 </h2>

簡單的郵件訊息輸入介面+附加檔案功能+可用HTML格式：
<html>
<head>
<title>JavaMail.html</title>
<meta http-equiv="Content-Type" content="text/html; charset=big5">
</head>
<body>
<h2>利用JavaMail來傳送電子郵件 - 附?#91;檔案</h2>
<form name="SendMessage" Method="post" action="JavaMail3.jsp" enctype="multipart/form-data">
