ubuntu org.apache.jasper.JasperException: 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

When finishing installing tomcat7 on Ubuntu 12.04.

Some example pages throw error (written in Title).

There is JSTL(I don’t know what it is exactly.)

I guess it’s not a big problem, so I googled, and decided ignoring error!!

However, if you’re interested in that error.

There is a great post in here. –> http://administratosphere.wordpress.com/2010/06/23/tomcat-missing-java-standard-tag-libraries-jstl-in-debian-and-ubuntu/
