Create a WFS 1.1 service in java

I wanted to create an OGC Web Feature Service (version 1.1) from scratch in java. When I tried to use jdk6 xjc with the OpenGIS schemas I had lots of errors so I had to create a bindings file to resolve them. It all works fine now, here are the results of my labours:

Ant fragment:

 <exec executable="${xjc}"
              failonerror="true"
              outputproperty="xjc.output"
              errorproperty="xjc.error"
              logerror="true">
            <arg value="-extension">
            <arg value="-verbose">
            <arg value="-httpproxy">
            <arg value="proxy:8080">
            <arg value="-b">
            <arg value="${opengis}/wfs/1.1.0/wfs-bindings.xml">
            <arg value="-d">
            <arg value="${generated}">
            <arg value="${opengis}/wfs/1.1.0/wfs.xsd">
            <arg value="${opengis}/cts/craft-feature.xsd">
            <arg value="${opengis}/ows/1.0.0/owsExceptionReport.xsd">
        </exec>

wfs-bindings.xml:
