发送邮件和java图形？

[dingdong1104]

我现在做一个性能管理系统，用户定制报告，要求在指定的时间生成比如对指定机子的内存的一段时间的柱状图示，并把这个图示发送到指定的油箱里。

我现在想问如何实现才能使之打开油箱能看到用户定制的内存柱状图示？

使用HTML格式的信件。

但不推荐，因为html信件对大多数收件人来说都是不受欢迎的，因为其中可能包含恶意script代码。

[dingdong1104]

如果按楼上的想法，那么我需要在服务器端用jsp?

[yayv]

不，你在服务器短没必要写jsp，写纯java代码就可以。

哦，我明白了，你误会我的意思了。

MIME提供了一种信件格式： text/html

你可以给自己发一封html格式的email，然后察看原始信息就能看到。使用foxmail/outlook/outlook express/mail(linux/unix)/pine(linux/unix)都可以。

这些功能使用j2ee sdk中的javax.mail包就可以完成。
