Hi William, Thanks for your reply.
My project uses OpenNLP 1.6.0. I have properly referenced both the *opennlp-tools-1.6.0.jar* and* opennlp-uima-1.6.0.jar* libraries. This is also reflected in the* .classpath* of my project. This error is therefore quite puzzling to me. I also have other projects using OpenNLP 1.6.0 yet they are able to load the model successfully.
