A4 BAD Protocol Error: "Specified set of flags is not valid"

Question

Hi there
I try to implement a copying procedure for mails. The application should copy all messages (with flags and all that stuff) from one mail account to another one. As mail server are used an Exchange 2003 Server and a Zimbra server (version 5). The connection protocol is IMAP. I'm using javaMail 1.4.0
Anyway, if I'm trying to copy a message which has set the flags RECENT and SEEN as well as some user flags, I get this error message:
javax.mail.MessagingException: A4 BAD Protocol Error: "Specified set of flags is not valid".;
  nested exception is:
     com.sun.mail.iap.BadCommandException: A4 BAD Protocol Error: "Specified set of flags is not valid".
     at com.sun.mail.imap.IMAPFolder.doCommand(IMAPFolder.java:2337)
     at com.sun.mail.imap.IMAPFolder.appendMessages(IMAPFolder.java:1289)
     at org.zimbra.exchange.MyTestClass.main(MyTestClass.java:323)
Caused by: com.sun.mail.iap.BadCommandException: A4 BAD Protocol Error: "Specified set of flags is not valid".

     at com.sun.mail.imap.IMAPFolder.doCommand(IMAPFolder.java:2332)
     ... 2 moreThis is a shortened source code which I'm using. In principle it is based on the sample files given in the documentation:
eStore = eSession.getStore();
eStore.connect(user, password);
zStore = zSession.getStore();
zStore.connect(userZimbra, passwordZimbra);
IMAPFolder fe = (IMAPFolder) eStore.getDefaultFolder().getFolder("inbox");
IMAPFolder f = (IMAPFolder) zStore.getDefaultFolder().getFolder("inbox");
f.open(Folder.READ_ONLY);
Message[] msgs = f.getMessages();
fe.appendMessages(msgs);Can someone help me and describe what I'm doing wrong??
thanks

Answer 1

Could You make an example?
I tried to subclass the class 'IMAPMessage' (messages which are returned with folder.getMessage() are of that type) and cast the messages to my new class. Unfortunately, I get always a 'ClassCastException'.
This are parts of my code:
public class MyIMAPMessage extends IMAPMessage {
     protected MyIMAPMessage(IMAPFolder folder, int msgnum, int seqnum) {
          super(folder, msgnum, seqnum);
          // TODO Auto-generated constructor stub
     public Flags getFlags() {
          Flags flags = new Flags();
          for (int i=0; i<flags.getSystemFlags().length; i++)
               flags.add(flags.getSystemFlags());
          return(flags);
f.open(Folder.READ_ONLY);
Message[] msgs = f.getMessages();
System.out.println(((MyIMAPMessage)msgs[0]).getFlags());
I think I do not exactly get your point. Maybe You could explain it a little more in detail.
