So it doesn't matter what my XSI schema URL is (web-jsptablibrary_2_1.xsd or bark.xsd), as long as the container has some file with a matching namespace URI and a matching version. Did I get this correctly? > > Does or offend your sensibilities to not have the "right" file name? Kind of, yea. I'm OCD. It's a personal problem, I know. I suppose the important point is, knowing that the JSP tag library specification is part of the JSP specification, regardless of schema URL or anything, I should be able to put the current JSP version in the tablib version attribute, but that won't work in this case, since the version would be 2.2 but Tomcat 7 doesn't have a 2.2 file, just a 2.1 file. There IS technically a JSP tag library 2.2 specification, it just doesn't actually differ from the 2.1 specification. So why can't I specify version 2.2? > >> This does not appear to be isolated to Tomcat.
