Eclipse - Maven project with Tomcat receives 404 Error

I go over the internet to figure it out why I receive 404 I tried almost all solutions and didn't help. I have:

  1. Eclipse Photom
  2. Tomcat 9
  3. Java version 1.8
  4. Maven project using Jersey 2.27

When I hit http://localhost:8080/Test/rest/testservice I got 404 "Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists."

I solved it. So if anyone experience problems with 404 even the fact that you did everything right then double check these steps:

  1. Always save (CTR + S) pom.xml and web.xml when you make any kind of modifications

  2. Replace index.jsp with index.html

  3. Right click the project go to Maven -> Update Project

  4. Right click the project go to Run as -> Run on Server (if I run it manually it doesn't work, but when I go from run as it is working correctly)

I have created a tutorial with step by step. If anyone wanted please contact me.
