I am using maven to create a dynamic webapp in Eclipse. I added some folders like src/test/java and src/test/resources. Also I changed the library in Java Build Path to obtain the JavaSE-1.7. It's all OK up to here.

When I tried to change the Projects Facet Dynamic Web Module something went wrong. I had change the Java to 1.7 in the same place. And it still told me, cannot change version of project facet Dynamic Web Module to 3.0.

I have changed everything that would effect the changing I think.

Another way is to edit the project facet configuration file itself: org.eclipse.wst.common.project.facet.core.xml

Change the dynamic web module version in this line to 3.0 - <installed facet="jst.web" version="2.5"/>

And then:

  1. Right-click on the project (in the Project Explorer panel).
  2. Select Maven » Update Project (or press Alt+F5)

You'll find this file in the .settings directory within the Eclipse project.
