I have been inserting log4j entries into a mongodb database and each entry has been given an ISODate timestamp:
"timestamp" : ISODate("2012-01-17T22:30:19.839Z")
To create a mapping for this, I had to manually add the timestamp as Spring Roo did not allow timestamp to be used as it was a reserved word.
So I manually added:
@DateTimeFormat(style="MM/dd/yyyy") private java.util.Date timestamp;
But I started getting the following error:
Invalid style specification: MM/dd/yyyy
The stack trace for that error was:

To fix this I attempted to add the ISO date format for the @DateTimeFormat
@DateTimeFormat(style="yyyyMMdd'T'HHmmss.SSSZ") private java.util.Date timestamp;
Which still did not work and had the error.
To resolve this I shitched to use ISO.DATE_TIME as the style:
@DateTimeFormat(iso=ISO.DATE_TIME) private java.util.Date timestamp;
