How to parse raw mime content in java?

I have raw mime message which contains html content, inline images and attachments.

I want to parse and display the content in html page as like as mail client are displaying.

Read message by using MimeMessage and MimeMultipart from

import javax.mail.Session;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import java.io.ByteArrayInputStream;
import java.util.Properties;
...

        Properties props = System.getProperties();
        Session session = Session.getInstance(props, null);

        ByteArrayInputStream is = new ByteArrayInputStream(emailMessage.getBytes());

        MimeMessage message = new MimeMessage(session, is);

        if (message.getContent() instanceof String) {
            return (String) message.getContent();
        }

        MimeMultipart content = (MimeMultipart)message.getContent();

        if (content.getCount() <= 0) {
            return null;
        }

        String contentString = (String) content.getBodyPart(0).getContent();

You need to read the file, then create a MimeMessage:

   // read the file
    StringBuffer fileData = new StringBuffer(1000);
    BufferedReader reader = new BufferedReader(new FileReader(new File(/*PATH*/)));
    char[] buf = new char[1024];
    int numRead = 0;
    while ((numRead = reader.read(buf)) != -1) {
        fileData.append(buf, 0, numRead);
    }
    reader.close();



// Create a MimeMessage


Properties props = System.getProperties(); 
Session session = Session.getInstance(props, null);
MimeMessage message = new MimeMessage(session, new ByteArrayInputStream(fileData.toString().getBytes()));

Now that you have a mime message you can have access to its content using:

message.getContent();

The content type will depend on the mime type (could be a String, a Multipart object...)

Here is the JavaDoc for MimeMessage.
