Java date and calendar controls

Question

Does anybody have any recommendations of good date pickers (either drop down calendars or small calendar components) for use in a Java Swing application - either beans or source code? They need to be robust enough for commercial applications.

Solution 1

JCalendar is free and provides beans and source code. It is quite configurable and in my applications so far served its purpose quite well.

Solution 2

I agree with Dan Dimerman and can recommend the swingX library. We use JXDatePicker within a commercial application as well. And with JXMonthView you've got the possibility to write your own variant of date picker.

Solution 3

you can use this one just change the main on your needs ^^
