Joda-Time (With EJB3) Page

Some developers prefer to use Joda-Time instead of Java's date and time classes.
Joda-Time can be used with Tapestry with the help of two components provided by JumpStart: InsertDateTime and DateMidnightPicker.
This page demonstrates the InsertDateTime component. It's similar to Insert, but it understands Joda Time's formatting.

First, we use InsertDateTime to display a database field: table DateStuff contains a column called dateMidnight. It's stored as an SQL DATE but the DateStuff object exposes it as a DateMidnight field. Here is InsertDateTime being used to render the DateMidnight field in various styles...

jwcid="@InsertDateTime":	date
jwcid="@InsertDateTime" style="S-":	date
jwcid="@InsertDateTime" style="M-":	date
jwcid="@InsertDateTime" style="L-":	date
jwcid="@InsertDateTime" style="F-":	date
jwcid="@InsertDateTime" formatter="ognl:french":	date
jwcid="@InsertDateTime" formatter="ognl:ISODate":	date

Some features of InsertDateTime:

The style parameter lets you specify a two-character Style pattern.
The formatter parameter lets you specify a DateTimeFormatter.
The component can render these Joda-Time classes: DateTime, DateMidnight, LocalDate, LocalTime, LocalDateTime.
It can also render these deprecated classes: YearMonthDay and TimeOfDay, for backwards compatability.
It can also render these Java classes: Date, Time, Number, java.sql.Timestamp, and java.sql.Date, for completeness.

Here is InsertDateTime being used with all 5 main Joda-Time types:

DateMidnight, style="L-":	date
DateTime, style="LL":	datetime
LocalDate, style="L-":	date
LocalTime, style="-L":	time
LocalDateTime, style="LL":	datetime
