"javax.ws.rs.NotFoundException: HTTP 404 Not Found" occurring after request

Question

I'm working on a Java8 Tomcat8 Jersey2 web app and it's randomly logging a bizarre exception after successfully responding to requests. I have a filter in place for all requests to do some logging and add some values to the MDC (e.g. requestId) and the exception is coming from here. Here's the stack:

The odd thing is though that the request was successfully processed and a success response (200 sent back to the calling client before this stack is showing up. I'm at a loss. Also, the line in the stack coming from my code (com.xyz.gatorws.webapp.LoggingFilter.doFilter(LoggingFilter.java:34)) is the following:

chain.doFilter(httpRequest, response);

This is bizarre given that the filter runs before the request is processed. Argh! I must be missing something. I clear the logging context in the LoggingFilter.destroy() method so I can't see that another request is involved, but I'm really at a loss.

Any thoughts would be much appreciated.

Answer 1

In case this can help the asker or others

My configuration was Java9 Tomcat9 Jersey2. I got a problem like this one cause the matched method wasn't annotated with any HTTP method annotation. In my case the @GET was missing. The method was returning a Response object and after the last statement before the return Response ... it was throwing NotFoundException. I think Jersey thought this method was a subresource locator that was found due to the @Path annotation.

So i changed from this:

@Path("unique/page")
@Consumes("*/*")
@RolesAllowed("owner")
public Response getUnique(@PathParam("userUUID") String userUUID) throws RuntimeException {
    LogNdc.log("userUUID: " + userUUID);
    SearchCompanieService scs = new SearchCompanieService();
    CompanyPagePojo cpp = scs.searchByFieldNameAutoCommit("userPojoOwnerId", userUUID);
    System.out.println(cpp);
    return Response.status(Status.OK).entity(cpp).build();
}

To this:

@Path("unique/page")
@GET
@Consumes("*/*")
@RolesAllowed("owner")
    public Response getUnique(@PathParam("userUUID") String userUUID) throws RuntimeException {
        LogNdc.log("userUUID: " + userUUID);
        SearchCompanieService scs = new SearchCompanieService();
        CompanyPagePojo cpp = scs.searchByFieldNameAutoCommit("userPojoOwnerId", userUUID);
        System.out.println(cpp);
        return Response.status(Status.OK).entity(cpp).build();

}

But in my case the request was not generating any 200 response code due to the exception, the client was getting 500 because I had a RuntimeExceptionMapper.
