WildFly quickstart 'spring-greeter' contains errors after import into Red Hat CodeReady Studio

Issue solved by extending the pom.xml by adding the following dependency:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
