Hi ,
I tried to create a sample servlet in aem 6.3 .

Please see below for the piece of code :

// all the import statements

@SlingServlet(

paths={"/bin/customservlet"}

)

public class Test extends SlingAllMethodsServlet {

private static final long serialVersionUID = 1L;

protected static final Logger LOGGER = LoggerFactory.getLogger(Test.class);

    @Override

    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {

    LOGGER.info("ENTERED THE SERVLET");

    }  

}

When I am trying to hit the servlet using locahost:4502/bin/customservlet  - it is giving the following message 

Resource at '/bin/customservlet' not found: No resource found

RequestURI=/bin/customservlet

Servlet= /apps/sling/servlet/errorhandler/404.html

I am not sure why  I am getting this error.I checked error logs as well which is giving the following error :

31.01.2018 11:01:08.475 *INFO* [0:0:0:0:0:0:0:1 [1517376668472] GET /bin/customservlet HTTP/1.1] org.apache.sling.engine.impl.SlingRequestProcessorImpl service: Resource /bin/customservlet not found

java.lang.Error: Unresolved compilation problems:

Only a type can be imported. com.adobe.cq.sightly.WCMUse resolves to a package

WCMUse cannot be resolved to a type

The method activate() of type ResponseStatus must override or implement a supertype method

The method getResponse() is undefined for the type ResponseStatus

at apps.sling.servlet.errorhandler.ResponseStatus.<init>(ResponseStatus.java:18)

Please let me know how I will be able to resolve it.

Thanks,
