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.
