那位大侠写过用javamail api和sun的pop3.jar来收信的?(255分)

小弟最近学习javamail,但是一直找不到有pop收信的帮助或文档请问各位大侠有一个小例子没有?或者哪里有pop收信比较详细的文档和javamail的文档?感觉不尽啊,我所以的分都送上了!

E文的要不要。

也要,但是不要是javamail自己带的那些,那个我看过,讲了等于没有

为什么要用java做？有点好奇。

用jsp+servlet来开发的webmail

>>但是不要是那些..,那个我看过,讲了等于没有
javamail自己带的不很好吗？

我给你一段源程序：

OK,我这摸够意思吧，给你这样长的原程序。

你写了这么多,我非常感谢,但是我问的是用sun的javamail api来实现收信
发信我都搞定了,就是不知道如何收,不知道孙老师试过那个javamail没?

看下面的代码：
import java.io.*;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class GetMessageExample {
public static void main (String args[]) throws Exception {
String host = "yourhost";
String username = "username";
String password = "password";
Properties props = new Properties();
Session session = Session.getInstance(props, null);
Store store = session.getStore("pop3");
store.connect(host, username, password);
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
BufferedReader reader = new BufferedReader (
new InputStreamReader(System.in));
Message message[] = folder.getMessages();
for (int i=0, n=message.length;
i<n;
i++) {
System.out.println(i + ": " + message.getFrom()[0]
+ "/t" + message.getSubject());
System.out.println(
"Do you want to read message? [YES to read/QUIT to end]");
String line = reader.readLine();
if ("YES".equals(line)) {
message.writeTo(System.out);
} else
if ("QUIT".equals(line)) {
break;
}
}
folder.close(false);
store.close();
}
}

怎么不能全部帖出来？下面是余下的：
Message message[] = folder.getMessages();
for (int i=0, n=message.length;
i<n;
i++) {
System.out.println(i + ": " + message.getFrom()[0]
+ "/t" + message.getSubject());
System.out.println(
"Do you want to read message? [YES to read/QUIT to end]");
String line = reader.readLine();
if ("YES".equals(line)) {
message.writeTo(System.out);
} else
if ("QUIT".equals(line)) {
break;
}
}
// Close connection
folder.close(false);
store.close();
}
}

capitain:代码全部帖出来了，只是没显示出来。
你用查看源文件的方法查看吧。

eguy很感谢!!!!!!!!!!,
还有一个小问题,收下来的是乱码
怎么才可以把它编码为可以看见的字符
用getbyte来转?还是有专门的类来解决?
要用到那些类,那些方法呢?
编码是在收信时就编码(用接口),还是收到本地再编码?
那个activetion的类这样的吗?可以给一个小例子?英文的都可以了
我现在一个人学,很需要入门的一些这方面的文档,
我愿意再出200分!

<p>sorry.我没有对代码测试。<br>
下面我改了一下。<br>
1。添加一个方法：<br>
public static void printParts(Part p) {<br>
try{<br>
Object o = p.getContent();<br>
if (o instanceof String) {<br>
System.out.println(&amp;quot;This is a String&amp;quot;<br>
System.out.println((String)o);<br>
} else
if (o instanceof Multipart) {<br>
System.out.println(&amp;quot;This is a Multipart&amp;quot;<br>
Multipart mp = (Multipart)o;<br>
int count = mp.getCount();<br>
for (int i = 0;
i &amp;lt;
count;
i++) {<br>
printParts(mp.getBodyPart(i));<br>
}<br>
} else
if (o instanceof InputStream) {<br>
System.out.println(&amp;quot;This is just an input stream&amp;quot;<br>
InputStream is = (InputStream)o;<br>
int c;<br>
while ((c = is.read()) != -1)<br>
System.out.write(c);<br>
}}<br>
catch (Exception e) {<br>
e.printStackTrace();<br>
}<br>
}<br>
2。将<br>
if (&amp;quot;YES&amp;quot;.equals(line)) {<br>
&amp;nbsp;&amp;nbsp;&amp;nbsp;
message.writeTo(System.out);<br>
} <br>
改为<br>
if (&amp;quot;YES&amp;quot;.equals(line)) {<br>
&amp;nbsp;&amp;nbsp;&amp;nbsp;
printParts(message);<br>
} <br>
</p>

多谢!我明白了
我现在也正在看那个javamail,
懂了许多,
多谢大哥了
以后还要多多请教!
