Am using Jersey 1.15, JDK 1.6, Tomcat 7, Maven 2.2.1 to create a simple Restful Web Service that should return a JSON String from a POJO that I mapped.

Here's my POJO:



my webservice:




Here's my pom.xml:



My web.xml:



After deploying to tomcat, when I try to invoke the web service like this:



I get the following error:



After scouring the Internet, I tried inserting the following proposed solution that everyone suggested into web.xml:



But it still gives me the same issue! It does return the correct data marshalled to XML if I use APPLICATION_XML, however.

Would really appreciate it if someone could point me in the right direction.

Thank you very much for taking the time to read this.

It is sorta covered in the JavaRanch Style Guide.
