java spring problem : project can not run on tomcat server even though edited the server.xml file?

Question

I am newbie with java spring and here is my problem.

I created a simple project named DiamonShop and tried to run it by tomcat 9.0.62.

But it show me this error

I think that the error is because of the file server.xml, because I have 2 projects named DemoSpringMVC and DiamonShop, in the file server.xml, I found that there is this line

<Context docBase="DemoSpringMVC" path="/DemoSpringMVC" reloadable="true" source="org.eclipse.jst.jee.server:DemoSpringMVC"/>
  <Context docBase="DiamonShop" path="/DiamonShop" reloadable="true" source="org.eclipse.jst.jee.server:DiamonShop"/></Host>

And the link http://localhost:8888/DemoSpringMVC/ worked perfectly When I changed the line above into this

<Context docBase="DiamonShop" path="/DiamonShop" reloadable="true" source="org.eclipse.jst.jee.server:DiamonShop"/></Host>

The link http://localhost:8888/DemoSpringMVC/ did not work, so I thought that maybe the link http://localhost:8888/DiamonShop/ must work? But it did not.

I also tried tomcat 8.5 and tomcat 10, but it showed the same error.

Here is my code (DemoSpringMVC and DiamonShop), for reference, if you need.

Here is my server.xml file

Here is my webapp at my apache-tomcat

Could you please give me some advices for this problem? Thank you in advance.

Most probably the docBase="DemoSpringMVC" you're referring to doesn't exist in webapp directory, because the war/jar file you might have built contains "SNAPSHOT" like strings.
