Good afternoon I am trying to run a java web service (.war) with the image of docker openjdk, I want to do this test, but I am getting that when I run the container I get the following error:

no main manifest attribute, in WebServices.war

My Dockerfile

FROM openjdk:12
COPY WebServices.jar WebServices.jar
CMD [“java”, “-jar”, “WebServices.jar”]

My web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="WebApp_ID"
    version="3.0">
  <display-name>WebServices</display-name>
   <listener>
     <listener-class>
        com.sun.xml.ws.transport.http.servlet.WSServletContextListener
     </listener-class>
   </listener>
   <servlet>
      <servlet-name>Hello</servlet-name>
      <servlet-class>
        com.sun.xml.ws.transport.http.servlet.WSServlet
      </servlet-class>
   </servlet>
   <servlet-mapping>
     <servlet-name>Hello</servlet-name>
     <url-pattern>/hello</url-pattern>
   </servlet-mapping>
 
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
</web-app>

How could I run this web service with an image like openjdk: 12 or java: 8?

In these examples I show continucaicon they do it:
