javax.servlet.ServletException: Not running on Jetty, JSR-356 support unavailable

Question

I am facing a problem while deploying a war on to tomcat instance,

Tomcat version details,

D:\Kiran\Kiran\Softwares DH\Webservers\apache-tomcat-7.0.63\bin>version.bat

POM Dependency :

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-websocket</artifactId>
</dependency>

I have created a war using maven plugin and tried to deploy on tomcat 7. I was able to deploy but unable to start the webapp. When I find the logs for it, it gave below stacktrace,

SEVERE: Error during ServletContainerInitializer processing

Any help would be appreciated. Thank you.

Edit :

It runs fine when I run the application using STS

Search in pom.xml for

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jetty</artifactId>
</dependency>

and remove it.
