How to parse a Mbox file with JavaMail API?

Question

I want to use JavaMail to parse an .mbox file just like this one http://mail-archives.apache.org/mod_mbox/lucene-java-user/201210.mbox.

What I thought of doing was:

Session session = Session.getDefaultInstance(new Properties());
Store store = session.getStore("Here should go the .mbox file");
store.connect();

Folder folder = store.getFolder(server);
folder.open(Folder.READ_ONLY);
...

Which proved wrong. Any suggestions would be helpful.

Thank you in advance.

Update: Working example

public class MBoxFileReader implements MessageReader {
    private final Path path;  // Path to .mbox file

    public MBoxFileReader(Path path) {
        this.path = path;
    }

    @Override
    public Message[] readMessages() {
        Message[] messages = new Message[0];
        URLName server = new URLName("mbox:" + path.toString());
        Properties props = new Properties();
        props.setProperty("mail.mime.address.strict", "false");
        Session session = Session.getDefaultInstance(props);
        try {
            Folder folder = session.getFolder(server);
            folder.open(Folder.READ_ONLY);
            messages = folder.getMessages();
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        return messages;
    }
}

Answer 1

You can use the JavaMail mbox Store, but you'll need to build it yourself.

Answer 2

This can be done with Apache Mime4j:

    CharsetEncoder ENCODER = Charset.forName("UTF-8").newEncoder();
    final File mbox = new File(mboxPath);

    for (CharBufferWrapper message : MboxIterator.fromFile(mbox).charset(ENCODER.charset()).build()) {
        System.out.println(message);
    }

you'll need:

<dependencies>
    <dependency>
        <groupId>com.sun.mail</groupId>
        <artifactId>javax.mail</artifactId>
        <version>1.6.1</version>
    </dependency>
