How to resolve Uncaught exception thrown by REST service: Unrecognized field "input"

Question

Hi I am writing a rest service where user enters the value in dialogue box and via Ajax it update the Active object table. But I keep getting Uncaught exception thrown by REST service: Unrecognized field "input".

@Consumes({MediaType.APPLICATION_JSON})
@Produces({MediaType.APPLICATION_JSON})
@Path("/message")
public class LeangearsRestResource {


    ActorConfService ActorConfService;

    private final ApplicationProperties applicationProperties;
    public LeangearsRestResource(ApplicationProperties applicationProperties, ActorConfService actorConfService){
        this.applicationProperties = applicationProperties;
        this.actorConfService = actorConfService;
    }
    static final javax.ws.rs.core.CacheControl NO_CACHE = new javax.ws.rs.core.CacheControl();

    @POST
    @Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
    public Response addMessage(ActorBeans actorBeans)
    {

        if(actorConfService.add(actorBeans.getActor(),actorBeans.getRole()))
        {
            return Response.ok(new Result(true)).cacheControl(NO_CACHE).build();
        }
        return Response.ok(new Result(false)).cacheControl(NO_CACHE).build();
    }

ActorBean.java

@XmlAccessorType(XmlAccessType.FIELD)
public class ActorBeans {


/*
    @XmlElement(name = "projectName")
    String productName;*/
    @XmlElement(name = "actor")
    String actor;
    @XmlElement(name = "role")
    String role;

    public ActorBeans() {
    }

    public ActorBeans(String productName, String actor, String role){
        /*this.productName = productName;*/
        this.actor = actor;
        this.role =role;
    }

    /*public void setProductName(String productName) {

        this.productName = productName;
    }

    public String getProductName(){

        return productName;
    }*/


    public String getActor() {
        return actor;
    }

    public void setActor(String actor) {
        this.actor = actor;
    }

    public String getRole() {
        return role;
    }

    public void setRole(String role) {
        this.role = role;
    }
}

message "Unrecognized field "input" (Class com.leanpitch.leangears.jira.webwork.beans.ActorBeans), not marked as ignorable"

Look at what you have here

data = {input:AJS.$("#dialoginput").val()};
data1 = {input:AJS.$("#dialoginput1").val()};

actor_createPostAjaxOptions(data, data1)
[..] 
"data": JSON.stringify(data, data1),

The message is pretty clear. It's saying you have JSON with an "input" field, which the server doesn't know how to process. Look at this

data = {input:AJS.$("#dialoginput").val()};

Whatever AJS.$("#dialoginput").val(), that is the value of the "input" field. So if the value is "value", then the JSON being sent is

{ "input" : "value" }

As far as data1, I don't think that's getting sent. AFAIK, JSON.stringify should only take one Javascript object as a data argument, that is the object it will stringify.

Now look your Java object

public class ActorBeans {

    @XmlElement(name = "actor")
    String actor;
    @XmlElement(name = "role")
    String role;

This means that the JSON expected is in the format

{ "actor" : "value", "role" : "value" }

JSON is pretty near the same syntax as JSON, so that's pretty much how the Javacript object should look. So you might have a Javascript object like

var data = {
    actor: AJS.$("#dialoginput").val(),
    role: AJS.$("#dialoginput1").val()
};

Then you can stringify that data to send.
