After spending lot of time I figured out that the issue was with maven dependencies not being in deployment assembly and I followed below steps.
Solution

1) Go to project properties
2) Select Deployment Assembly
3) Click on Add
4) Click on Java Build Path Entries
5) Click Next
6) Select Maven Dependencies
7) Click Finish & OK
8) Restart your server
