OK, this is probably another newbie question, but let me try. I have
this testing program to copy all messages from one mbox folder to
another maildir one:

So, with help from people on I found a solution which
at least compiles and works somehow. However, not correctly. This is the

   import java.util.*;
   import javax.mail.*;

   public class CopyFolder {

       * @param args
       * @throws MessagingException
      public static void main(String[] args) throws \
            MessagingException {
         String urlStr = "/home/matej/.eclipse/workspace"+
         Session session = Session.getInstance(new \
         URLName storeURL = new URLName("mbox://"+urlStr);
         Store mboxStore = session.getStore(storeURL);
         Folder mboxFolder = mboxStore.getDefaultFolder();
         mboxFolder = mboxStore.getFolder("test");;
         URLName store2URL = new URLName("maildir://"+
         Store maildirStore = session.getStore(store2URL);
         Folder targetFolder = maildirStore.getDefaultFolder();
         targetFolder = targetFolder.getFolder("target");
         if (!targetFolder.exists()) {
            try {
               targetFolder.create (Folder.HOLDS_MESSAGES);
            catch(Exception e) {
               System.err.println("Cannot create target foldr: "+
               throw new RuntimeException(e);
         System.out.println("name of the folder is "+
         Message[] messages = mboxFolder.getMessages();
         System.out.println("There are "+mboxFolder.getMessageCount()+
               " messages in the source folder");
         System.out.println("There are "+messages.length+
        " messages in the selection");
         System.out.println("There are "+targetFolder.getMessageCount()+
               " messages in the target folder");



However, when I run it I don't get expected results:

[matej@hubmaier kmail2tbfolders]$ rm -rf examples/output/
[matej@hubmaier kmail2tbfolders]$ ls -lh examples/
celkem 2,0M
-rw-rw-rw- 1 matej matej 2,0M kv?? 2 20:23 test
[matej@hubmaier kmail2tbfolders]$ java CopyFolder
name of the folder is target
There are 40 messages in the source folder
There are 40 messages in the selection
There are 0 messages in the target folder
[matej@hubmaier kmail2tbfolders]$ find examples/output/target/* -type f |
wc -l
[matej@hubmaier kmail2tbfolders]$

And truly there are only 6 messages in the create maildir folder. Any
ideas why this doesn't work as expected? I feel so close, and yet I am
still not there!

Thanks for any reply,
