Elastic Beanstalk Servlet过滤器上的AWS Tomcat

Question

I'm trying to launch my web application for the first time on AWS Elastic Beanstalk (platform: Tomcat 8 with Java 8 running on 64bit Amazon Linux/3.0.0).

It succeeds in creating the application in beanstalk but when it tries to launch my application (uploaded with a war) it throws an error:

The SecurePathFilter is a javax.servlet.Filter class so I'm thinking it might be that jsp and servlet api jars are missing on the tomcat (or perhaps some other version of what I used locally) but how can I check this? And how could I add/change them?

Edit: As requested, the relevant pieces of my web.xml:

<filter>
    <filter-name>SecurePathFilter</filter-name>
    <filter-class>be.qsds.sade.filters.SecurePathFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>SecurePathFilter</filter-name>
    <url-pattern>/secure/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
</filter-mapping>

and my SecurePathFilter class is roughly:

public class SecurePathFilter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException, ServletException {
        ...

        filterChain.doFilter(request, response);
    }
}

@jontro led me in the right direction of the solution to my problem. I was building my application locally with the latest version of javax.servlet-api (4.0.1), where the Tomcat8.5 auto deployed on AWS uses an older version (3.1.0).

I changed the version in my pom, added some missing methods, rebuilt and uploaded my war and eureka!

Thanks for the guidance!
