2. Add the following code to the <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>
3. On the Eclipse project, right-click to refresh the project
4. Right-click on the project to enter properties
5. Click on "Project Facets" in the list item on the left, select "Dynamic Web Module" and "Java" on the right, click OK to save.
