Sentence detector constructor and models

[IamLove]

Hi,
I am using the OpenNLP library in my java project for sentence detection. I have this code:

final String fs = System.getProperty("file.separator");
final String path = "C:" + fs + "Users" + fs + "Zdravko" + fs + "Documents" + fs + "Job" + fs + "EnglishSD.bin.gz";
sd = new SentenceDetector(path);

The code must load the model for English sentences, located in C:\Users\Zdravko\Documents\Job
Unfortunately, upon runtime I get this exception on the constructor line:

xception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: opennlp/maxent/DataStream

Could you give me any idea why? I would be grateful for any comments.
Thanks in advance!

I got it. The problem is that I missed the maxent and trove jar libraries.
