Hi everyone,

I wanted to get started with the StanfordCorenlp library in Java. I added the library with the correct dependencies to the project. After that I wrote a simple program that should display the sentiment of a couple of sentences. I made two classes: Pipeline and SentimentAnalysis

Pipeline class:

SentimentAnalysis class:

When i run this code i get the following error.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I have no idea what is causing this problem.

Probably the models file isn't in your classpath
