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: WARNING: Parse Warning Error at line 6 column 19: schema_reference.4: Failed to read schema document 'web-jsptaglibrary_2_0.xsd', because 1) could not find the document;
