I've updated psi-probe's WEB-INF/tld/probe.tld so it now contains:
<taglib xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd" version="2.0">
I'm not sure if I've misunderstood something, from Mark's email I thought I just needed to update the xsi:schemaLocation as above (and restart tomcat). But I'm still getting the same error messages at startup:
