javamail and gmail

  1. The following code throws IndexOutOfBoundsException. Any idea why? 

     Folder folder = store.getDefaultFolder();
 folder = folder.getFolder("INBOX");

 int totalMessages = folder.getMessageCount();
 //totalMessages is 17000

  folder.getMessages(16900, 16999)   --- here I am trying to get the NEWEST 99                                                                                         messages.

This code throws the exception indexoutofbounds even though there are so many mails. What am I doing wrong?

  1. folder.getMessages() - get all the emails from 1st email to last. In my case 17000!! How do I get the emails starting from newest to oldest? I only want to see the latest emails - around 100 of them. Is this possible?

please open the folder in read or read_write mode first.

folder.open(Folder.READ_WRITE);

Never us magic values in code, it will just cause you pain. Try:

int messagesToDisplay = 100;
folder.getMessages(totalMessages  - messagesToDisplay , totalMessages);

From the JavaDoc the messages are identified with a 1 based array not 0.

Can you also add the stack trace please.
