RESTful webservice doesn't start on Tomcat 8.0.5

Question

I wrote a simple webservice that parses an XMLfile with JAXB. This service works when I 'Run' it from the menu of NetBeans(Tomcat 8.0.3), But if I put the WAR file into webapps folder of tomcat and start tomcat(server.xml is identical between the two servers), I get the following error:

Please help resolve this:

Check if your servlet-api is included several times with:

mvn dependency:tree -Dverbose

If so, you can exclude transitional dependencies in one of them using (example of how I fixed same problem):

<dependency>
    <groupId>org.glassfish.jersey.test-framework.providers</groupId>
    <artifactId>jersey-test-framework-provider-jetty</artifactId>
    <version>2.23.2</version>
    <exclusions>
        <exclusion>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>
