this is my first time to use JBDS, i was following a exemple in the doc to create my first seam application then i stopped in step 3 in project facet to choose which features i want in my project(axis2 web service,dynamic web module,java,JP,JSF,seam.web docklet).

i realized this feature isn't present in my IDE.my question is do i need to configure something?why configure project facet isn't present in my IDE?
