I am using Apache CXF for making a simple restful application. I have a client class which posts a JSON object to the server and server returns back a JSON after some manipulation. but when i execute the code i get
"org.apache.cxf.interceptor.Fault: .No message body writer has been found for class:
class org.codehaus.jettison.json.JSONObject, ContentType : application/json."
My client code :
public class Client {
public static void main(String[] args) {
try{
URI uri = new URI("http://localhost:8022/RestDemo");
WebClient client = WebClient.create(uri);
String ret = client.path("rest").path("server").path("welcome").accept(MediaType.TEXT_PLAIN).get(String.class);
System.out.println(ret);
JSONObject json = new JSONObject();
json.put("name", "ronaldo");
json = client.path("rest").path("server").path("op").type(MediaType.APPLICATION_JSON).accept(MediaType.APPLICATION_JSON).post(json, JSONObject.class);
System.out.println(json);
System.out.println(json.has("reverse")?json.getString("reverse"):"dont have");
}catch(Exception e){
System.out.println("e"+e.getLocalizedMessage());
e.printStackTrace();
}
}
}
Please help.
I had the same problem and I am using CXF 2.7. The org.apache.cxf.jaxrs.provider.JSONProvider
has been changed to org.apache.cxf.jaxrs.provider.json.JSONProvider
So the jaxrs
provider is:
<jaxrs:providers>
<bean class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
<property name="dropRootElement" value="true" />
<property name="supportUnwrapped" value="true" />
</bean>
</jaxrs:providers>
