2014-07-26 17:35:43,968 ERROR [org.apache.catalina.startup.HostConfig] Error
deploying configuration descriptor
/etc/tomcat7/Catalina/www2.pingtoo.com/examples.xml
This is because the standard tomcat7 distribution no longer ships a copy of
jstl.jar. Instead,
/usr/share/tomcat7-examples/examples/WEB-INF/lib/jstl.jar is a symlink to
../../../../java/jstl1.1.jar. (The same applies to standard.jar).
The solution is simple. When I add allowLinking="true" to the Context element
of examples.xml then the webapp starts normally.
