Access GMail with imap using java mail api

 

I had to search through quite a few web pages for this. So I am putting it here for future reference. My conscience pricks for putting all the code in main method. But I guess this is an exception. 


import java.util.Properties;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.NoSuchProviderException;
import javax.mail.Session;
import javax.mail.Store;
public class InboxReader {
public static void main(String args[]) {
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
try {
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imaps");
store.connect("imap.gmail.com", "<username>", "password");
System.out.println(store);
Folder inbox = store.getFolder("Inbox");
inbox.open(Folder.READ_ONLY);
Message messages[] = inbox.getMessages();
for(Message message:messages) {
System.out.println(message);
}
} catch (NoSuchProviderException e) {
e.printStackTrace();
System.exit(1);
} catch (MessagingException e) {
e.printStackTrace();
System.exit(2);
}
}
}



Use the code below to get the available gmail folders for your account
 

Folder[] folder = store.getDefaultFolder().list();

// get the array folders in server
int i=0;
for( i=0;i<folder.length;i++)
System.out.println("Press "+i

 +" to read "+folder[i].getName()+" folder");
int choice=in.nextInt(); 

// getName() method returns the name of folder
