Eclipse 3.2: How to let an old project support "project facet"?

[Henry Leung]

When I right-click on a newly created "dynamic web project" and choose "Properties", there is a "Project Facet" section, in which I can add/remove project facets.

But when I try to do the same thing to our existing web project (created by WSAD 5.1), there is no "Project Facet" section in the "Properties" list. How can I make it appear, so that I can add/remove project facets?

Henry,
It's probably a setting/builder in the .project file. Try comparing a project created in Eclipse 3.2 to the WSAD 5.1 one and see what has been added.

Thanks Jeanne!

I compared our WSAD project to a new Eclipse 3.2 project, found that the Eclipse project has a few more lines in its .project file. Those lines are:

  
<nature>org.eclipse.wst.common.project.facet.core.nature</nature>
<nature>org.eclipse.wst.common.modulecore.ModuleCoreNature</nature>
<nature>org.eclipse.jem.workbench.JavaEMFNature</nature>

I added them to our WSAD project's .project file, then the "Project Facets" section appeared.
