In short: The Web server is not configured.

Right-click the item on which the error occurred-->build path-->configure Build Path

When adding the server library step, there is an empty option, what if there is no Tomcat 7.0 choice?

1. Choose Eclipse's Windows menu Preferences preset

2. Locate the Server item in the list on the left, expand, check: Runtime environments, right click Add button

3, here to choose according to the version of Tomcat you use, not necessarily Tomcat 7.0;

I'm here to demonstrate adding Tomcat, and of course you can choose to add IBM Liberty, or a Web server like JBoss (Java ee container)

If you have not installed Tomcat, you can go to the official website to download a compressed package extracted to a directory.

4. Click the Browse button to choose where Tomcat is located

Choose JRE (Java Runtime Environment), of course you can use Eclipse's own,

But if you want to use your own installed version you need to add a bit, beginners to use their own on it;

5, the above all ready click on the Finish button will be OK.
