I can't browse for a servlet to be my Welcome File, but the paragraphs "Servlets as Welcome Files" in the link below says that it's possible with 2.4/2.0/Tomcat5.x: http://www.onjava.com/lpt/a/4553
Yes, I would qualify this as an enhancement. There is a workaround to write the servlet mapping manually.
OK. Please note that this issue is also applicable to error pages. In other words, it should also be possible to select a servlet as an error page. See: http://java.sun.com/developer/EJTechTips/2003/tt0114.html
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
