Hi I'm new to all this. I have been trying to display fetched emails in a JTable using the JavaMail add-on. However when I ask the program to set the value it never does. I have been working in NetBeans if that is any help? the fetchMail class finds all may on a server. The gui class is used to display all emails in a table as well as creating mail.

You will probably think that I have tried it like a bull in a china shop, I am new to Java and trying to give myself a challenge. Any help/advice would be greatly appreciated

fetchMail:

    // SUBSTITUTE YOUR SUBJECT SUBSTRING TO SEARCH HERE!!!

    // Get a session.  Use a blank Properties object.
