            @Consumes(MediaType.APPLICATION_JSON)

    // ajax call 
         $.ajax({
                 url: "http://localhost:8080/FirstRestWebService/rest/newentry",
                 type: "post",
                 data: formToJSON(),
                 dataType : "json",
                 success: function(data){
                alert("success");
                  },
               error:function(jqXHR, textStatus, errorThrown) {
                    alert("failure");
                  }   
            }); 

         function formToJSON() {
                return JSON.stringify({
                    "name": $("input#emp_name").val(),
                    ...
                    "username": $('input#username').val(),
                    "password": $('input#password').val()
                    });

回答1:

In your AJAX call you need to set your content type:

contentType: "application/json"

回答2:

You must declare the JSON dependency. Please try to add the following dependency to your pom.xml.

 <dependency>
    <groupId>com.owlike</groupId>
    <artifactId>genson</artifactId>
    <version>0.98</version>
</dependency>
