Serialising Mail Objects

Dear User-Group,

I would like to use JAMES to store incoming emails in text files and need some guidance here.

Is the way to go using java.io.Serializable ?


I saw that org.apache.mailet.Mail implements java.io.Serializable.

I have managed to serialisable it to file and read it back while running JAMES.

But strangely, if I make a testclass which runs from the copied BLOB

objIn = new ObjectInputStream(new BufferedInputStream(new FileInputStream("data/spool/MAILOBJECT.BIN")));
			org.apache.mailet.Mail mail = (org.apache.mailet.Mail) objIn.readObject( );

it comes to

java.io.StreamCorruptedException: unexpected end of block data
	at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1296)
	at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1845)
	at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1769)
	at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1646)
	at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1274)
	at java.io.ObjectInputStream.readObject(ObjectInputStream.java:324)
	at eon.SendEmailFromBlob.start(SendEmailFromBlob.java:19)
	at eon.Spool2Mail.main(Spool2Mail.java:11)

I have copied the .jar from the running james installation to the testclass to make sure that the same Mail object is used.


Any other ideas how to store mails including their headers with mailets ? 


Thank you ,

Thilo Müller

Hi Thilo,

Why you not just use the FileStore to store messages in the inbox in
the filesystem ? Do you need to implement your own store ?

Bye,
Norman
