interface to stanford parts-of-speech tagger

[ahsan1]

This is the program in java which is an interface to stanford postagger. I have attached a copy of it. I am using netbeans 6.7.1 . I have placed the model file which is "left3words-wsj-0-18.tagger" in the bin folder of jdk and also placed the stanford-postagger.jar in that folder.
I have included the the stanford project in the src folder of netbeans projects so I could import files easily.But when I run this program, it gives following errors or exceptions:
run:
Enter sentence(s) to be tagged:
large cats eat small rats.

Exception in thread "main" java.lang.ExceptionInInitializerError
at testing.PosTagger.tag(PosTagger.java:18)
at testing.PosTagger.main(PosTagger.java:125)
Caused by: java.lang.RuntimeException: Uncompilable source code - type parameter edu.stanford.nlp.ling.TaggedWord is not within its bound
at edu.stanford.nlp.tagger.maxent.MaxentTagger.<clini t>(MaxentTagger.java:189)
... 2 more
Java Result: 1
BUILD SUCCESSFUL (total time: 24 seconds)

How do I remove these errors to run it successfully?
