Re: [jetty-users] JSP using Java 1.7?

Look at the example contexts in the distribution.
You'll need to have the following set in your WebAppContext.
<Set name="defaultsDescriptor"><SystemProperty name="jetty.home" default="."/>/etc/webdefault.xml</Set>

Thanks, but I'm still not having much luck here. I didn't have a contexts directory (I only have a single context). I tried creating one, moving my webapp to "/demo", and putting the above in a "demo.xml" file:

  <Configure class="org.eclipse.jetty.webapp.WebAppContext">
    <Set name="contextPath">/demo</Set>
    <Set name="defaultsDescriptor"><SystemProperty
      name="jetty.home" default="."/>/etc/webdefault.xml</Set>
  </Configure>

I also tried putting it in jetty-env.xml and jetty-web.xml in the
WEB-INF directory, but that didn't work (picked up too late I
presume?). I seem to be just thrashing around here simply in order
that webdefault.xml will be used as per the documentation. Sorry
if I'm being a bit dumb. I have a configuration that I set up a couple
of years ago by trial and error, and it worked fine until I decided
to try moving to JDK 1.7, and now I find I don't really know how it
all works!

The error message I get is not terribly useful: "use -source 7 or
higher to enable try-with-resources"; I can't find anything about
"-source 7" anywhere in any documentation! And I have no idea how
to find out which XML files are being read or in what order when I
start the server.

My setup is minimal (I don't want to use the whole of the distro,
as most of it I don't need) -- I'm just trying to create a basic
JSP service for a specific app. My lib directory just contains
the jars I seem to need:

  jsp/*
  jetty-continuation-8.1.4.v20120524.jar
  jetty-http-8.1.4.v20120524.jar
  jetty-io-8.1.4.v20120524.jar
  jetty-security-8.1.4.v20120524.jar
  jetty-server-8.1.4.v20120524.jar
  jetty-servlet-8.1.4.v20120524.jar
  jetty-util-8.1.4.v20120524.jar
  jetty-webapp-8.1.4.v20120524.jar
  jetty-xml-8.1.4.v20120524.jar
  servlet-api-3.0.jar

My jetty.xml looks like this:
