Get started with Liberty
and again SuperSnoopServlet worked without problems, with a default server.xml : -
<?xml version="1.0" encoding="UTF-8"?>
<server description="new server">
<!-- Enable features -->
<featureManager>
<feature>webProfile-7.0</feature>
</featureManager>
<!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
<httpEndpoint id="defaultHttpEndpoint"
httpPort="9080"

<!-- Automatically expand WAR files and EAR files -->
