I think I must be getting closer, but I'm still getting the same error. Now
that I'm escaping the *, the path seems correct.
Here are my current environmental variable settings:
$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home
$JENA_HOME
/Users/username/Documents/jena/apachejena370
echo $JENAROOT
/Users/username/Documents/jena/apachejena370
$ echo $CLASSPATH
/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/bin:/Users/
username/Documents/jena/apachejena370/lib/*
When I run the code:
$ sudo java Tutorial01
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/jena/rdf/model/ModelFactory
at Tutorial01.main(Tutorial01.java:34)
Caused by: java.lang.ClassNotFoundException: org.apache.jena.rdf.model.
ModelFactory

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
... 1 more
I've also somehow broken something because javac is no longer working:
$ sudo javac Tutorial01.java
Tutorial01.java:21: error: package org.apache.jena.rdf.model does not exist
import org.apache.jena.rdf.model.*;
