Louis,
The exception means that the classpth does not contain the jena-core
jar. Put all the jars from the distribution lib directory in the
classpath. Nowadays in java you can put '...\lib\*' on the classpath and
it will include all the jars in that directory.
See the bat scripts in the download or
https://github.com/apache/jena/tree/master/apache-jena/bat
then print out the classpath to make sure it is right.

I'm getting Apache Jena set up and am having some issues. I think my issue

Here is what I've posted on Stack Overflow:
Based on this tutorial
<http://staff.um.edu.mt/cabe2/lectures/webscience/docs/jena.pdf> I've
gotten my workspace set up. I've removed the package identifier from my code
The way to call main is to use it's full name, package included:
java -cp ... <fullname>
java -cp ... a.b.C
where C has the static main method
<https://stackoverflow.com/questions/36402759/error-could-not-find-or-load-main-class-classdemo>
.
Now I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/jena/rdf/model/ModelFactory at
Tutorial01.main(Tutorial01.java:34)
Caused by: java.lang.ClassNotFoundException:

I think it's a JENAROOT Issue. I think I'm setting it and adding it
<https://stackoverflow.com/questions/28177971/tdbloader2-fails-with-classpath-error/28181902#28181902>
to the path correctly. It's also mentioned here
<https://jena.apache.org/documentation/tools/>, but I haven't been able to
troubleshoot it yet.
Anybody can point me in the right direction?
Thanks,
Louis
