<P> JSP页面的作用就是获得表单提交过来的数据，并将这些数据赋给Java Mail

<P> 如何发送HTML类型的邮件 </P>
<P> 在上面的例子中，我们实现了如何发送文本格式的邮件，那么HTML格式的邮件该如何发送呢？那就看看下面的例子吧。<BR> 该例由四个文件组成：<BR> ·form.htm：用来建立邮件信息的表单<BR> ·send.jsp：用来获取表单提交的信息，并调用mymail.mail.HTML.send()方法发送邮件<BR> ·StringDataSource.Java：用户自定义的JavaBean，用来将邮件的Body部分转化为HTML格式<BR> ·HTML.Java：用户自定义的JavaBean，用来发送HTML格式的邮件。在send.jsp文件中提到的mymail.mail.HTML.send()方法就在该JavaBean中定义。
