A small red fork appears when you import a Web project into your hands first

First click on the item in the right mouse button--"Select Properties

On the right side of the pop-out window, select the "Libraries" tab, select the place where the Red fork appears, and click "Edit ..." on the right. Button

Change it to your eclipse's operating environment JDK1.8-->JDK 1.7, Tomcat 8--and Tomcat 7

2. If all of the above steps are done, the Little Red fork disappears, but when you publish the project to Tomcat, you find the selected

The button posted to Tomcat 7 is grayed out, and this is where Eclipse's "project storage" is supposed to be found--"Find this item"

--"Click Open File Project Folder"--"Find the. Settings folder, click"-"Find the Org.eclipse.wst.common.project.facet.core.xml file"

--"Notepad open will be inside"

<?XML version= "1.0" encoding= "UTF-8"?><Faceted-project>  <Runtimename= "Apache Tomcat v8.0"/>  <fixedfacet= "Wst.jsdt.web"/>  <fixedfacet= "Jst.web"/>  <fixedfacet= "Java"/>  <installedfacet= "Java"version= "1.8"/>  <installedfacet= "Jst.web"version= "3.1"/>  <installedfacet= "Wst.jsdt.web"version= "1.0"/></Faceted-project>

Modify the appropriate version and environment

For example, modify the following

<?XML version= "1.0" encoding= "UTF-8"?><Faceted-project>  <Runtimename= "Apache Tomcat v7.0"/>  <fixedfacet= "Jst.web"/>  <fixedfacet= "Wst.jsdt.web"/>  <fixedfacet= "Java"/>  <installedfacet= "Java"version= "1.8"/>  <installedfacet= "Jst.web"version= "3.0"/>  <installedfacet= "Wst.jsdt.web"version= "1.0"/></Faceted-project>

Then it will be released!!!!
