Based on URL you are sharing, you are using wrong URL you have to use

localhost:8080/myapp/tramps

not

localhost:8080/myapp/WEB-INF/views/tramps/list.jsp

to invoke controller method, if you are new in spring mvc please check my YT channel

I am not for sure this is the root cause of your problem, but your code has at least two errors.

You need to specify "beans" prefix to the bean entry in your servlet-context.xml.

<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <beans:property name="prefix" value="/WEB-INF/views/" />
    <beans:property name="suffix" value=".jsp" />
</beans:bean>

tramp variable in your list.jsp does not have "key" and "value" property since its type is String.

<c:forEach var="tramp" items="${tramps}">
    <tr>
        <td>${tramp}</td>
    </tr>
</c:forEach>

Hope this helps.
