Hi Tim, The most likely cause seems to be that the model file represented by "sentenceModelPath" can't be found. You need to make sure that the binary model file is on the class path, which it probably is in your Eclipse environment, but not in the test server environement. Or you can try get the InputStream for the resource file like so: InputStream fstream = this.getClass().getResourceAsStream(sentenceModelPath);
