I have created a test project in order to learn Jersey. I have created the following classes Book.java (Model), BookDao.java, BookResource.java and so far everything works just fine. My problem is with a JerseyTest i am trying to run (BookResourceTest.java). I am using Jackson for JSON serialization.
When i run the test i get this error: Error reading entity from input stream.
This is the console output:
