1, into the project directory, to find the. project file, open.
2, find <natures>...</natures> code section.
3, in the 2nd step of the code snippet add the following label content and save:
<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>
4. classpath files under the project directory, change all Webroot strings to webcontent and save them.
5, the directory under the Webroot folder renamed WebContent.
6, add the libraries of the Web server to the Java resources:src directory in Eclipse, select Biuldpath----->configure build Path------> Select Add Library under the current window----->server Runtime------> select the Web server you want
7. Right-click the project on Eclipse and refresh the project.
8, on the project point right key, enter the property (properties)
9. Click "Project Facets" on the left-hand list item, select "Dynamic Web Module" and "Java" on the right, click Save.
You should be able to start the project normally under Eclipse.
Personal feeling that a lot of steps are useless. The most critical step is the nineth step.
