Failed to load IMAP envelope

Question

Hi All,
     I have encountered a problem with JavaMail API, when a message exists on the Mail Server that has �null� for recipient field, JavaMail API throws an Exception when ever we try to retrieve getFrom() method, and also it returns �null� when I was retrieving BCC list.
Is there any thing wrong in this code, Pls. help me?
My Sample code:
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;
import javax.mail.internet.InternetAddress;
import javax.mail.Address;
public class InboxSearch
     public static void main(String[] args)
          String           host          =     "XX.X.XXX.XX"; //Host
          int               port          =     143;     //Port No          
          String           user          =     "XXXXXX";     //Username
          String          password     =     "XXXXXX"; //Password
          Properties      props          =      new Properties();
          Store          store          =     null;
          Folder          inbox          =     null;
          try
               Session session = Session.getDefaultInstance(props, null);
               store = session.getStore("pop3");
               store.connect(host,user,password);
               inbox = store.getFolder("INBOX");
               inbox.open(Folder. READ_WRITE);
               Message[] inboxMessages = inbox.getMessages();
               for (int counter = 0; inboxMessages!=null && counter <inboxMessages.length; counter ++)
                    Address from[] = inboxMessages[counter].getFrom();
                    //when i was retrieving it throws javax.mail.MessagingException:Failed to load IMAP envelope
                    String retriveBcc=null;
                    Address bcc[] = inboxMessages[counter].getRecipients(Message.RecipientType.BCC);
                    for (int bcccount = 0; bcc != null && bcccount < bcc.length; bcccount++)
                         retriveBcc = retriveBcc + bcc[bcccount];
                         if ((bcccount + 1) < bcc.length)
                              retriveBcc = retriveBcc + ", ";
                         System.out.println("BCC->"+retriveBcc);
                    //retrieving with BCC field it return null so it will throws NullPointerException
          catch (NoSuchProviderException nspe)
               System.err.println("invalid provider name"+ nspe.toString());
          catch (MessagingException me)
               System.err.println("messaging exception"+ me.toString());
          catch(Exception e)
               System.err.println("exception"+ e.toString());
          finally
               try{ if(store!=null){store.close();}}catch(Exception e){}
               try{ if(inbox!=null){inbox.close(true);}}catch(Exception e){}
     }//main end
}//class end

Hi All,
Thanks for your replay, Is there any way to find out which column is causing �inserted value too large for column� the problem? I'm trying to insert the data into a table by using Prepared Statement.
Note that I don't require like email_id length>column length then column name=�EMAIL_ID�
Appreciated ur help,
