Make sure you don't have any conflicting jars between what is in your
WEB-INF/lib and what is in ${jetty.home}/lib/jspKeep in mind that Jetty itself, and even the maven plugin, isolates these differences for you with a webapp classloader. But with ANT you have no such safety net, so you have to be extra careful to not have duplicate classes in both places. A common scenario for that error is having 2 different (jstl) standard taglib jars. -- Joakim Erdfelt <[email protected]> webtide.com <http://www.webtide.com/> Developer advice, services and support from the Jetty & CometD experts eclipse.org/jetty - cometd.org On Thu, Nov 8, 2012 at 8:40 AM, Johnson, Wayne <[email protected]>wrote: > I am migrating a webapp from Jetty6 (stop laughing, it's worked well for > years) to Jetty8 and I'm getting the following error: > > org.apache.jasper.JasperException: > file:D:/dev/HEAD/eadev/clients/java/cfgmgr/jsp/displayAttribute.jsp(7,62) > PWC6188: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be > resolved in either web.xml or the jar files deployed with this application > > This compile use to work in Jetty 6 but now fails.
