Answered on stack overflow.... you are setting the web.xml as the
default descriptor, so it is being run twice.
Don't set the default descriptor.

I have written a very simple test Filter, and am running it in an
embedded Jetty 9.2.18.v20160721 in debug mode in IntelliJ IDEA:
|System.out.println(TestFilter.class.getSimpleName()// line 12+" >
"+((HttpServletRequest)servletRequest).getRequestURL()+": IP
"+servletRequest.getRemoteAddr()+"; at "+newDate().toString());//
Pass request back down the filter
chainfilterChain.doFilter(servletRequest,servletResponse);// line 20}|
and added it to web.xml:
|<filter><filter-name>TestFilter</filter-name><filter-class>net.twentyonesolutions.TestFilter</filter-class></filter><filter-mapping><filter-name>TestFilter</filter-name><url-pattern>/*</url-pattern>
</filter-mapping>|
When running in debug mode in IntelliJ IDEA, the Filter's
doFilter() method is called twice, and the output from line 12 is
written twice. You can see the stack trace at the 2nd call below.
When I deploy the Filter to regular Jetty (same version), or
Tomcat, the output from line 12 is only written once, as expected.
Why is this happening in debug/embedded mode? TIA I posted this
question with a bit more detail at
