No options for Select deployment server in NetBeans

I’m trying to run a Java Spring project in NetBeans, and the following Select deployment server window opens:

window

But in that dropdown Server list there are no options available, although I have Tomcat running in the Services tab. What is going on?

Answer

The issue is resolved. This project was not created in NetBeans, it was imported from zip file. So I recreated the project as a web application and pasted the source files in the new project and it worked. When you create a web application, there’s a step where you are asked about the server type. I chose Tomcat there. Also when you you create a project from scratch, NetBeans adds a file called nb-configuration.xml, where this choice is remembered. And in the initial project this file wasn’t present.
