JAX-RS - JSON without root node

Question

I have a restful web service, and the response is:

{
    \"cities\": [{
        \"id\": \"1\",
        \"name\": \"City 01\",
        \"state\": \"A1\"
    }

I had the same problem with Glassfish v3. I found this behavior depends on the JAX-RS implementation and switching to Codehaus' Jackson JAX-RS implementation solved the problem for me.

If you're using Glassfish as well, then you can solve the problem by adding org.codehaus.jackson.jaxrs to your war as well as to the WEB-INF/web.xml configuration as follows:

  RESTful Services
  com.sun.jersey.spi.container.servlet.ServletContainer
  
    com.sun.jersey.config.property.resourceConfigClass
    com.sun.jersey.api.core.PackagesResourceConfig
  
  
    com.sun.jersey.config.property.packages
    you.service.packages;org.codehaus.jackson.jaxrs

  RESTful Services
  /your/rest/path/*

Alternatively, you might be able to simply intercept the response in the client:

function consumesCity(json) {
   ...
}

Replace

... consumesCity(json) ...

with

function preprocess(json) {
    return json.city;
}

... consumesCity(preprocess(json)) ...
