You could have added the word transient on the field declaratio, this way JBossSerialization wont have used it.
I asked you about the version because there were some problems with JBossSerialization used on JBoss 4.0.4 RCLatest. I created a testcase serializing a SimpleDateFormat, and it works fine. If you upgraded your version you would probably have your test working. Also, just some TIPs non related to your post: - be careful on moving SimpleDateFormat to a static class since it's non multi-thread. - I actually (as a programmer) would recommend to not use SimpleDateFormat unless your formatting is stored in a database field since its performance is pretty bad, hence Apache created some FastDateFormat classes. Two cents from someone who wrote a Profiler.
