The namespace java:comp/env is reserved to be local to a webapp. That
is, it is designed to be called from code executing from the
associated WebAppContext. You cannot reference it from outside of the
webapp. The specification calls for names defined within the
container's namespace (via Resource declarations in jetty-env.xml or
jetty.xml) to be hooked up into webapps via <resource-ref> entries in
web.xml - this populates the java:comp/env namespace for a webapp.
Given the way you have defined your datasource Resource, if you want
to access it outside a webapp, you need to access it within the global
namespace as:
InitialContext ic = new InitialContext();
ic.lookup("jdbc/testDS");
