Besides the LAFs that are shipped with Java itself, additional third party LAFs can be added to Servoy, by placing the LAF library in the {servoyInstall}/application_server/lafs directory.

 A word of caution on third party Look And Feels

There are many third party Look And Feels around for Java, both free/open source LAFs and commercial LAFs. The quality of these LAFs differs, so when opting to use a third party LAF, make sure to properly test the LAF in combination with the developed Solution in Servoy. A public listing of the majority of the available third party LAFs can be found on http://www.javootoo.com/
