Re: [jetty-users] Virtual host proxy problems

For ProxyServlet the logging category is derived from the servlet name

The logic is here:
https://github.com/eclipse/jetty.project/blob/jetty-9.4.x/jetty-proxy/src/main/java/org/eclipse/jetty/proxy/AbstractProxyServlet.java#L206
Enabling DEBUG for that category should tell you a bit more.
Hmm, I seem to be doing something wrong. The servlet-name in web.xml is
"Proxy", and the servlet-class is "servlets.Proxy". I created a
resources/jetty-logging.properties which looks like this (copied from
the example in the documentation):
# Configure Jetty for StdErrLog Logging
org.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.StrErrLog
# Overall Logging Level is INFO
org.eclipse.jetty.LEVEL=INFO
# Detail Logging for proxy
Proxy.LEVEL=DEBUG
I then get a 500 response due to a NPE at line 65 of
ProxyServlet.service(): "if (_log.isDebugEnabled())..."
I then copied the code you linked to into my Proxy.init() and it
reported the servlet name as "servlets.Proxy.Proxy", but changing the
last line to "servlets.Proxy.Proxy.LEVEL=DEBUG" makes no difference; I
still get the same NPE. I also tried "servlets.Proxy.LEVEL=DEBUG"; still
no luck.
What am I doing wrong here?
