First you need a copy of the
Tomcat webapp server installed, which you can download as a ZIP file from tomcat.apache.org. Please note that depending on whether your
JEE packages are using the old version packages such as javax.http.Servlet or the newer Jakarta EE packages, you'll need either Tomcat version 9 or lower (old packages) or Tomcat 10 or greater (jakarta.ee).
To install Tomcat, simply unzip it. To deploy your WAR, just copy it into the tomcat
webapps directory.
Now start Tomcat: run the Tomcat
bin\startup.bat command.
The correct URL for a WAR named
AntTestProp would be
127.0.0.1:8080/AntTestProj/AddTwoNumbers.html - 124 is a mis-typed value. Instead of 127.0.0.1, you can also say
localhost.
