Karaf 4.2.7 + Servlet Multipart java.lang.NoClassDefFoundError: org/eclipse/jetty/util/MultiPartInputStreamParser

[Davi Baldin Tavares]

Hi Karafers,

A) In case I use Annotation:

@WebServlet(name = "Sendgrid Inbound Parse receiver", urlPatterns = "/inbound")
@MultipartConfig
public class SendGridServlet extends HttpServlet implements Servlet { … }

I’m getting:

2020-06-07T11:59:47,485 | WARN  | qtp423783131-158 | HttpChannel                
      | 114 - org.eclipse.jetty.util - 9.4.20.v20190813 | /sendgrid/inbound
java.lang.NoClassDefFoundError: 
org/eclipse/jetty/util/MultiPartInputStreamParser

I’ve found:

https://issues.apache.org/jira/browse/CAMEL-14105

B) In case I use Camel suggestion…

                Collection<Part> parts = request.getParts();
                parts.forEach((part) -> {
                        log.info("Part --> {} : {} ", part.getName(), 
part.getSize() );
                });

I’m getting:

2020-06-07T12:14:23,180 | WARN  | qtp423783131-160 | HttpChannel

java.lang.IllegalStateException: No multipart config for servlet
        at org.eclipse.jetty.server.Request.getParts(Request.java:2215) ~[?:?]


C) In case I try this workaround: 
https://www.eclipse.org/lists/jetty-users/msg03294.html, I get the same issue 
as A (annotation).

What is the correct way to get working with multipart in Karaf?

Thanks,

Davi
