此處利用java mail來寄信，java mail是J2EE中較晚加入的API，使用時需另外安裝Java Mail和JavaBeans Activation Framework兩個package。

利用session得到validate.jsp所傳遞過來的資料
String username = (String) session.getAttribute("a");
String body = (String) session.getAttribute("b");
String myname = (String) session.getAttribute("c");
String toaddress = (String) session.getAttribute("d");
String fromaddress = (String) session.getAttribute("e");
String picture = (String) session.getAttribute("f");
String mypicture = (String) session.getAttribute("g");
template.txt中記錄著電子賀卡外?#91;的樣板，以下?#123;式將使用者輸入的資料套入樣板，最後結果存入變數content中

int index = 0;

while ((line = reader.readLine()) != null)
{
if (line.indexOf("%getpic%") > 0 )
{
index = line.indexOf("%getpic%");
line1 = new StringBuffer(line);
if(picture.equals("other"))
{
line1.replace(index,index+8, mypicture);
}
else
