I would recommend jCalendar for your date picker widget.
Just right-click on the swing palette, then choose Palette Manager and from there you can add the jCalendar Jar files.
Question
I am using WindowBuilder (Eclipse Juno 4.2) to create GUI for my project. In that GUI I need to use date picker. I searched online for some date pickers and found out some library that will do work but for some reason I can't implemet it in WindowBuilder. Is there any Date picker that will work (that can be added as a Window Builder component) with WindowBuilder. Regards.

OTHER TIPS
For SWT there is an internal date picker but also a myriad of widgets in the Eclipse Nebula project.
