Answer 1

要安装 Javamail，您应该查看 ReadMe .其中指出:

Note that the JavaMail API requires the JavaBeans(TM) Activation Framework package to be installed as well if you're using JDK 1.5 or earlier. Download the latest version of the JavaBeans Activation Framework from

http://www.oracle.com/technetwork/java/javase/index-jsp-136939.html

and install it in a suitable location.

和

1. Unzip the javamail1_4_5.zip archive. (You may have already done this.)

2. Set your CLASSPATH to include the "mail.jar" file obtained from the download, as well as the current directory.

   Assuming you unzipped javamail1_4_5.zip in c:\download the following would work:

   set CLASSPATH=%CLASSPATH%;c:\download\javamail-1.4.5\mail.jar;.

   Also, if you're using JDK 1.5 or earlier, include the "activation.jar" file that you obtained from downloading the JavaBeans Activation Framework, in your CLASSPATH.

   set CLASSPATH=%CLASSPATH%;c:\download\activation\activation.jar

3. Go to the demo directory

4. Compile any demo using your Java compiler. For example:

   javac msgshow.java

5. Run the demo. The '-' option lists the required and optional command-line options to successfully run any demo. For example:

   java msgshow -

   lists the available options. And

   java msgshow -T imap -H -U -P -f INBOX 5

   uses the IMAP protocol to display message number 5 from your INBOX.
