Answer 1

For me, the fix was simple:

• Go here in the Eclipse menu: Project | Properties | Project Facets
• Ensure "Java" and "Dynamic Web Project" are selected
• Click OK

You may need to also do this:

• Go here in the Eclipse menu: Project | Properties | Java Build Path | Libraries
• Remove "Web App Libraries"
• Click "Add Library"
• Choose "Web App Library". Click "Next"
• Choose your project in the drop down
• Click OK

Answer 2

If you have imported your existing project then , first add Server(Window>Preference>Server>Run Time environment) to your work space and then re-import your project.

or Option 2 Goto Project properties > Targeted RunTimes and select your server

This should add web library to your project.

Answer 3

For me, Brad Parks's answer didn't worked in Eclipse Luna ( 4.4.2 ) i.e. Adding Web App Libraries had no effect ..that remained empty.

What I had to is to configure Web Deployment Assembly ...My lib was in WEB-INF which was again like - /{project}/web/WEB-INF/lib and when I added a Deployment Assembly entry like shown below ,

Then below these two I had an entry for every jar from {project}/web/WEB-INF/lib directory with Deploy Path as WEB-INF/lib.

This Deployment Assembly automatically populated my Web App Libraries.
