}

This is the example form Stanford's site and I was trying to read the contents from a file and I am getting the below Exception at the line where the StanfordCoreNLP (props) constructor is called:

Exception in thread "main"

Any help is appreciated. Thank you!

Refer the 9th question in

http://nlp.stanford.edu/software/corenlp-faq.shtml#nosuchmethoderror

It says,

"It is because you also have old versions of one or more Stanford NLP tools on your classpath"

and also have a look on,

https://mailman.stanford.edu/pipermail/java-nlp-user/2013-November/004357.html

which says,

Clearly there is some jar file incompatibility. Do you have any older versions of our tools in your classpath?
