title: Missing option "Run on Server" in Eclipse STS
body: <p>I am new to Spring and I wanted to learn how to develop REST APIs using Spring so I have followed this tutorial:</p>
  
  <p><a href="https://spring.io/guides/gs/rest-service/" rel="nofollow">https://spring.io/guides/gs/rest-service/</a></p>
  
  <p>I am using STS and the problem is that when I try to run it, I dont have a "Run on Server" option. Why ? Sorry for the noob question</p>
  
  <p>Regards</p>
