I'm still interested to hear if anyone's actually gotten verbose output to work. I tried configuring commons logging with log4j, but that didn't seem to have any impact.
So, two potential workarounds came to mind. Only one of them succeeded, but I think the one that failed uncovered another bug. Here's the one that failed: Keep taglib directive in JSP the same: <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %> Add a taglib element to web.xml: <taglib> <taglib-uri>http://java.sun.com/jstl/core</taglib-uri> <taglib-location>/WEB-INF/tlds/c.tld</taglib-location> </taglib> Extract TLD from taglib JAR and place in /WEB-INF/tlds. This produces the same error with the same args passed to the TagLibraryInfoImpl ctor: prefix: c uriIn: http://java.sun.com/jstl/core location: { /WEB-INF/lib/standard.jar, META-INF/c.tld } This seems to indicate that Jasper is replacing explicit taglib map entries with implicit entries. According to the JSP 1.2 spec (JSP.7.3), implicit entries should only be added if the value of their taglib-uri is not already contained in the taglib map. With that in mind, here's what does seem to work: Modify the uri attribute of the taglib directive in JSP: <%@ taglib prefix="c" uri="/tlds/jstl/core" %> Add a taglib element to web.xml: <taglib> <taglib-uri>/tlds/jstl/core</taglib-uri> <taglib-location>/WEB-INF/tlds/c.tld</taglib-location> </taglib> Extract TLD from taglib JAR and place in /WEB-INF/tlds. This results in a clean run with the following args passed to the TagLibraryInfoImpl ctor: prefix: c uriIn: /tlds/jstl/core location: { /WEB-INF/tlds/c.tld, null } I guess the next step should be to submit these as bugs, but I thought I'd round out the thread in case anyone else runs into the same sort of problem...
