I have recently made a Java project with Sphinx4. I found this code online, and I slimmed it down to this to test if Sphinx4 was working:
public class App
{
private static final String ACOUSTIC_MODEL =
"resource:/edu/cmu/sphinx/models/en-us/en-us";
private static final String DICTIONARY_PATH =
"resource:/edu/cmu/sphinx/models/en-us/cmudict-en-us.dict";
public static void main(String[] args) throws Exception {
Configuration configuration = new Configuration();
configuration.setAcousticModelPath(ACOUSTIC_MODEL);
configuration.setDictionaryPath(DICTIONARY_PATH);
configuration.setGrammarName("dialog");
LiveSpeechRecognizer jsgfRecognizer =
new LiveSpeechRecognizer(configuration);
jsgfRecognizer.startRecognition(true);
while (true) {
String utterance = jsgfRecognizer.getResult().getHypothesis();
if (utterance.startsWith("hello")) {
System.out.println("Hello back!");
}
else if (utterance.startsWith("exit")) {
break;
}
}
jsgfRecognizer.stopRecognition();
}
}
However, it gave me this error:

I thought it might be something about it not being able to find the paths for ACOUSTIC_MODEL or DICTIONARY_PATH, so I changed the resource: strings to things like %HOME%\\Downloads\\sphinx4-5prealpha-src\\sphinx4-5prealpha-src\\sphinx4-data\\src\\main\\resources\\edu\\cmu\\sphinx\\models\\en-us or paths with forward slashes or with C:\Users\Username\... but none of the paths worked. I know the paths exist because I copy and pasted them from the properties window of the actual resources.
So my question is: is it some of the code that I deleted from the original source code that is causing this error, is it something wrong with the paths, or is it entirely different?
EDIT
By the way, I am using Maven to build my project. I added the dependencies specified on the Sphinx4 website to my pom.xml, but it didn't work (it didn't recognize imports such as edu.com.sphinx.xxx) so I downloaded the JARs from the website they said to download them from and added them to my projects "Libraries" in my Java Build Path in Eclipse.
