Re: [jetty-users] Embedded Jetty 9 + JSTL = 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
|
James,
Prior to 9.2, jetty used the jsp impl from glassfish. This impl
requires that the jstl jars are on the server's classpath - ie on the
parent of the webapp's classloader. So putting the jstl jar into
WEB-INF/lib will not work. Neither can the jstl jar be unpacked onto
the classpath - it must appear as a jar. So you need to modify the way
you're setting up your executable jar to ensure that the jar
containing the jstl .tlds is found on a classloader that is the parent
of the webapp.
Also, just to be sure you've got the right mix of jetty, jsp and jstl
jars: run the jetty-maven-plugin with -X argument, and you'll see the
list of jars that plugin has on its classpath (ie the server
classpath) as compared with the webapp dependency jars (the virtual
'WEB-INF/lib'). Compare the plugin classpath jars to the ones you are
using with your executable jar.
regards
Jan
