gwt-jackson is a JSON parser for GWT. It uses Jackson 2.x annotations to customize the serialization/deserialization process.

Code) Code) Code)
Generator currently fails when it tries to parse Void type.
A stack overflow happens with parameterized classes that use themselves as a parameter, like:
interface IdentifiableEntity<T extends IdentifiableEntity<T>> {}Found in issue #44.
It would be nice if
com.github.nmorel.gwtjackson.client.AbstractObjectMapper
methods
protected JsonSerializer getSerializer()
and
protected JsonDeserializer getDeserializer()
were public. Then a custom serializer/deserializer could delegate object deserialization/serialization.
For example if we're deserializing a typed map (Map<String,Object>) where map key defines value type and the values are POJOs.
Or is there a better way to do it?
When looking for fields to serialize/deserialize, the generator does not ignore the static fields.
Now that we can add custom serializer and deserializer, let's add an extension library for Guava
Can you please update the examples, and offer a new one which shows how to use object inheritance.
Hi, I would like to see the @JsonIgnoreProperties annotation added to the library.
Currently, any rest service which changes any property of a result breaks the call with a message like:
...
Caused by: com.github.nmorel.gwtjackson.client.exception.JsonDeserializationException: Unknown property 'the_new_property_field'
Thanks
Currently, generators are really hard to read and understand.
Writing code at hand and the lack of comments are the main issues.
The generated code is also hard to read because there are no import, I only use qualified class names.
javapoet could be a nice solution.
Hi,
I have an exception during compilation: http://pastebin.com/b6Uf7EBt
I use: java 1.7, gwt 2.6.1 gwt-jackson 0.6.2.
The error is somewhere here:
public static interface ResponseMapper extends ObjectMapper<Response> { }
public static ResponseMapper MAPPER = GWT.create(ResponseMapper.class);
Response is an interface:
*/
@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "@class")
@JsonSubTypes({@JsonSubTypes.Type(value = ErrorResponse.class), @JsonSubTypes.Type(value = MessageResponse.class)})
public interface Response {
}
And has 2 implementations. One of them is MessageResponse:
package org.csgid.ucl.common.shared;
import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import java.io.Serializable;
public class MessageResponse extends Response {
public MessageResponse() {
}
@JsonCreator
public MessageResponse(@JsonProperty("message") String message,
@JsonProperty("data") Serializable data) {
this.message = message;
this.data = data;
}
private String message;
private Serializable data;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Serializable getData() {
return data;
}
public void setData(Serializable data) {
this.data = data;
}
}
I tried everything: changed Response interface into abstract class, put the initialising code into different part of code, moved getters/setters declarations into the interface, moved GWT.crate either into onModuleLoad method or into view implementation constructor.
Please help,
Jacek
GWT version should be uptated to 2.6.1 (currently the last version).
And Jackson from 2.3.2 to 2.4.2
What's the correct way to handle this?
/rest/clients -> returns json of List
/rest/clients/id -> returns json of Client
The main docs say to use
public static interface ClientMapper extends ObjectMapper {}
Should there then also be a
public static interface ClientMapper extends ObjectMapper<List> {} ?
Would this not generate duplicate code?
Hey I am using 0.6.2 and getting these errors on compile: http://pastebin.com/vKJneM4x

Is this possible or even logical? Thanks!
When including your library in my project, here's where the GWT compilation fails:
[INFO] Validating units:

[INFO] [ERROR] Aborting compile due to errors in some input files
I think your <inherits name="com.fasterxml.jackson.annotation.JacksonAnnotation" /> is causing this?
I tried running your example in the README.
First of all, I think you should remove <scope>provided</scope> from
<dependency>
<groupId>com.github.nmorel.gwtjackson</groupId>
<artifactId>gwt-jackson</artifactId>
<version>0.1.0</version>
<scope>provided</scope>
</dependency>
in the README, otherwise users will not be able to resolve the dependency at runtime.
Finally, I tried your example using the Person class. Serialization to a String works just fine. However, when I try to deserialize the string into a Person, I run into a JsonDeserializationException exception:
// ...
Caused by: com.github.nmorel.gwtjackson.client.exception.JsonDeserializationException: Cannot instantiate the type

Here's what the fields of AbstractBeanJsonDeserializer look like when I'm stepping into the public T doDeserialize( JsonReader reader, JsonDeserializationContext ctx ) method:
Any ideas?
Thanks a lot, I really like where this project is going so far.
Getting build errors while the serialization is compiling. Not even sure why its trying to compile this class for serialization tbh:

}Not really sure what's going on here. Any ideas?
I looked at a few source files, and there's no license header.
What's the license? Can I use this lib on a private, for-profit project?
Thanks man!
So I have a situation coming from GWT RPC serialization. GWT allowed you to provide an interface type as a return type and then you return an object that implements that interface. It appears gwt-jackson doesn't offer this kind of deserialization?
I have an interface called ProcessPageData which has 2 implementors:
Unable to deserialize response. An unexpected error occurred.
Cannot instantiate the type nz.co.doltech.ims.shared.core.ProcessPageData`
Depending on the process that is being loaded it returns the appropriate data in the form of the class. This worked fine previously and I would love to know how this could be done with jackson.
Cheers!
(Also, sorry I don't know where else to post questions that I have :D)
Hi @nmorel, congratulations for your excellent project! It is well designed.
I'm working on Turbo GWT HTTP - a project for GWT client/server communication. It's a high level API for managing and performing requests gracefully.
I let the de/serialization job for third-part libraries. By studying the available solutions, I really liked this one.
It would be great if you could help me out on building a integration for auto-serialization in turbogwt-http with gwt-jackson.
The interfaces for de/serialization are Serializer and Deserializer (joined in Serdes).
In turbogwt-http there's a main component, called Requestor, responsible for integrating the others. It's a factory for creating requests and later enhancing them (analogous to the Jackson ObjectMapper for serialization puporses). Custom serdes must be registered in the Requestor in order to be used in the requests.
It would be interesting to design some auto-discovered serdes registration for custom objects.
Are there any difference in the de/serialization process of Set, List and any of these implementations?
I am very interested in using your product. In my project, Jackson is currently being used on the server-side to do serialization/deserialization into json. We'd love to be able to integrate gwt-jackson into our GWT GUI as well.
However, we use mix-in annotations (mostly to @JsonIgnore methods) so that we can keep our POJOs free of serialization-related annotations.
It would be great if gwt-jackson supported mix-in annotations.

I have a DTO which contains a String json property, which obviously contains JSON (ie : {"json":"{\"key\":\"value\"}"}.
When serializing, I end up with an IndexOutOfBoundsException when calling out.append(value, last, i-last) in method JsonWriter.string(String value)
I found another issue.
If using @JsonIdentityInfo, to eliminate serializing the same instances of objects, gwt-jackson doesn't work, if "id" property is a parameter of the @JsonCreator constructor. I get an error:
I prepared a simplified test case (I omitted the obvious imports and other non-important code).
I have a simple TestDto, which has a list of "X" objects.
public class TestDto {
public List<X> list;
}
@JsonIdentityInfo(generator=ObjectIdGenerators.PropertyGenerator.class, property="id")
public class X {
public String id;
public String value;
public X() {
}
@JsonCreator
public X(@JsonProperty("id") String id) {
this.id = id;
}
@JsonProperty
public void setId(String id) {
this.id = id;
}
}The input JSON string that I try to deserialize into TestDto:
{
"list" :
[
{
"id" : "1",
"value" : "abc"
},
{
"id" : "2",
"value" : "test"
},
"1"
]
}However, if I remove "id" property from @JsonCreator, then it works.
The problem is that gwt-jackson generator doesn't include the properties that are parameters of @JsonCreate in the "AbstractBeanJsonDeserializer.initDeserializers" method. But @JsonIdentityInfo needs such a property to be included in the list of deserializers. The "setId" setter in my example is there only to demonstrate that even an explicit setter doesn't force the property's deserializer to be added to the list.
So I guess gwt-jackson should either include all the properties in the list of deserializers (would cause a small overhead, that would be later eliminated by gwt compiler), or at least those that are referenced by @JsonIdentityInfo.
I realized that gwt-jackson has guava as a dependency. Is this required, or optional?
Guava is a library of considerable size, and having the option of what you want to depend is always good.
If I have a Map<> that contains some wildcard parameterized type as a value, like:
Map<String, List<SomeClass<?>>>
then I get warnings like:
Type 'java.lang.Enum' is not supported as map's key
Subtype 'java.util.EnumMap' is not supported. We ignore it.
I know it's just a warning and since my parameter will never be an Enum or EnumMap, I can ignore it. But this warning still puts junk into the log. And this happens for every such Map. So with many Maps, I get many warnings.
Is there any way to disable or hide it?
I identified two places where Map implementations are used:
https://github.com/nmorel/gwt-jackson/blob/master/gwt-jackson/src/main/java/com/github/nmorel/gwtjackson/rebind/BeanJsonSerializerCreator.java#L146
https://github.com/nmorel/gwt-jackson/blob/master/gwt-jackson/src/main/java/com/github/nmorel/gwtjackson/rebind/BeanJsonDeserializerCreator.java#L324
I would like to be able to change these implementations.
Particularly, I would set them to LightMap, which is a lightweight Map implementation from String to Objects.
Is it easy to add support for @JsonInclude ?
Beside, the jsckson version may be upgraded to 2.5.0.
I would like to use gwt-jackson in the client side in my GWT project without Maven. Which jars do I need from which urls exactly?
I tried the following without success:
Add a mechanism to add custom serializer/deserializer.
It could be use to make addon libraries for guava or jdk8 date time api.
Does gwt-jackson support bounded wildcards? I'm having compilation errors, but I was just wondering whether you've actually implemented support for bounded wildcards.
E.g.:
public class MedicationDto {
// ...
private List<? extends Therapy> therapies;
// ...
}
I'm using gwt-jackson 0.4.0.
I just found this Project and think it is awesome to have this.
But i have a small issue. gwt-jackson can't deserialize some of my classes.
I have:
class StuffMap extends HashMap<String, Something> {
// bunch of helper methods but no json fields.
}and
class StuffList extends ArrayList<SomethingElse> {
// bunch of helper methods but no json fields.
}While gwt-jackson works if have ObjectMapper<Map<String, Something>> it does not if i do ObjectMapper<StuffMap>. With original Jackson this works and it would be awesome if it would be possible to use this with gwt-jackson too, to have easier access to those helper methods.
Thanks.
public class MyPojo {
@JsonProperty("@id")
String myIdReference
}
Will result in illegal code generation
private native void set@id(.....
When using Object or unbounded in some serializable class, gwt-jackson will try to process all the classes in the class path, as every class matches Object or . This can lead to many problems.
We already talked about the case of the class, parameterized with itself, like "class A<T extends A>". However, such classes were found to cause stack overflow, so we rewrote such classes to be simple un-parameterized classes.
But, if we have such self-parameterized class which is never meant to be used by gwt-jackson, it's still processed in the above cases, where gwt-jackson is processing all the class candidates. It's just enough that such class is in the class path, and is found and causes stack overflow.
gwt-jackson processes such classes, even if they are intentionally annotated with @JsonIgnoreType.
Is there anything to do in such a case? Like whitelisting or blacklisting the classes, or packages, or something? To process every class on the classpath is just not ok, even if we forget the fact that this can be very slow.
After we added gwtp-dispatch-rest which depends on gwt-jackson our project GWT compilation started failing with these messages:

Probably, this issue is somehow related to issue #3. But that was fixed in 0.2.0. Our project transitively depends on 0.4.0. We tried to fix the problem by upgrading maven dependencies to their latest releases and even snapshots, but it didn`t help.
Is it a bug or error in our configuration?
I could be wrong, but it seems like some kind JSON-related auxiliary classes are generated while GWT compiles our GWT standard RPC services. I am not sure that we actually need it. So any suggested workarounds are highly appreciated!
Attempting to create a deserializer for a type containing a 2D array generates Java classes with fail to compile to GWT.

Here's a (simplified) example of the class that causes the problem:
public class GameMapData
{
private final String[][] tileIds;
public GameMapData(@JsonProperty("tileIds") String[][] tileIds)
{
super();
this.tileIds = tileIds;
}
public String[][] getTileIds()

And here's the offending snippet of generated code:

});
}
I'm currently working on a big GWT project, and more precisely on a proof of concept to use JSON with Jackson on the server side, gwt-jackson on the front size. The RPC services we try to migrate use complex objects. I tried several libraries, gwt-jackson is the only one to purpose solutions for some difficulties (inheritance with generics, complex map keys...).
But I actually have problems with some enums, which have the particularity to implement interfaces. The current serializer/deserializer for enums are ok with plain simple enums, but do not permit the use of interfaces with JsonTypeInfo annotation, and enums implementing them. I don't think that's a heavy feature, but it would be a great one here =)
I tried this use case: http://www.studytrails.com/java/json/java-jackson-Serialization-list.jsp
@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = As.PROPERTY, property = "@class")
@JsonSubTypes({ @Type(value = Lion.class, name = "lion"), @Type(value = Elephant.class, name = "elephant") })
public abstract class Animal {
@JsonProperty("name")
private String name;
public Animal(String name) {
this.name = name;
}
...
}
class Elephant extends Animal {
@JsonCreator
public Elephant(@JsonProperty("name") String name) {
super(name);
}
...
}
class Lion extends Animal {
@JsonCreator
public Lion(@JsonProperty("name") String name) {
super(name);
}
...
}
// In Xtend GWT code:
val lion = new Lion("Simba")
val elephant = new Elephant("Manny")
val List<Animal> animals = #[lion, elephant]
val AnimalListMapper animalListMapper = GWT.create(AnimalListMapper)
val AnimalMapper animalMapper = GWT.create(AnimalMapper)
GWT.log(animalMapper.write(animals.get(0))) // {"name":"Simba"}
GWT.log(animalListMapper.write(animals)) // [{"name":"Simba"},{"name":"Manny"}]
Is there a way to write/read type information along with the objects?
(I'm new to Jackson so probably I just don't use the correct annotations?)
Thanks for your help in advance!
I apologize if this isn't a gwt-jackson issue, I am just running out of options with this. I haven't changed anything that should be causing this issue and can't find a solution. If you have any advice I'd be really grateful to say the least.

For some reason I can load the Incident object now, but I can't send it to the server. This was working earlier, then all of a sudden just stopped working and started throwing this error. Really hard for me to say what change is causing this though because they are all such light changes.
I tried reverting back to 0.6.2 but it still throws this exception.

Is it possible to have one ObjectMapper instance that's capable of mapping many classes, like a regular Jackson ObjectMapper?
All the examples here seem to create one mapper per class (eg PersonMapper extends ObjectMapper {}), whereas a normal Jackson ObjectMapper can take any old class at runtime.
Thanks, and keep up the good work - this library could save me a lot of effort!
com.github.nmorel.gwtjackson.client.exception.JsonSerializationException: java.lang.StringIndexOutOfBoundsException: String index out of range: -17I am getting this error when serializing a somewhat large object. What could be causing this?
sorry it works fine
I am using resty-gwt and it i depends on your project.
I use Map<String,Object> as DTO both in server side and client side.
GWT
@Path("http://localhost:8081")
public interface WhService extends RestService {
@POST
@Path("/{methodUrl}")
public void postRequest(@PathParam("methodUrl") String methodUrl,Map<String,Object> request,MethodCallback<Map<String, Object>> callback);
}if the Object is String, I can convert it into String type.
But,if the Object is List, when i use
(List<String>) whProduct.get("infoUrls") //this one not work,java.lang.ClassCastExceptio
String sku = whProduct.get("sku"); //this one work.Are the any plans to support PTH?

I'm having some difficulties parsing this JSON data :
{
"class":"com.myproject.common.shared.dispatch.GetResult",
"exceptionMessage":null,
"payload":{
"user":{
"class":"com.myproject.common.shared.business.identity.User",
"id":3,
"username":"admin",
"email":"[email protected]",
"password":"Test1234",
"firstName":"Admin",
"lastName":"Admin",
"authority":["ROLE_ADMIN","ROLE_USER"]
},
"customeUI":{
"id":1,
"headerBackgroundColor":"#00699B",
"headerFontColor":"#ffffff",
"headerFontHoverColor":"rgb(190, 190, 190)",
"siderBackgroundColor":"#191919",
"siderSelectedMenuColor":"#ffffff",
"siderHoverMenuColor":"#111",
"siderFontColor":"#ffffff",
"siderSelectFontColor":"#333",
"siderMenuBorderTop":"#212121",
"siderMenuBorderBottom":"#0a0c0e",
"siderMenuHoverBorderLeft":"#111"
}
}
}
Can't deserialize the user property.
The "com.myproject.common.shared.business.identity.User" class is a parent class and have a child class "com.myproject.common.shared.business.identity.BackUser".

This resolves the issues I was having with the ArrayList, I would need a way to specify the collection types I guess. Unless there is a really smart way to do this.
Add some kind of benchmark project to compare the performance of different serialization mechanism (piriti, resty, errai).
Hello!
I don't find a way how to serialize some other object inside the "doSerialize" method of my custom serializer that extends JsonSerializer.
Let's say I have classes A and B, and A contains field of type B. Now I have custom JSON serializers for both classes A and B and inside AJsonSerializer's doSerialize, I want to write the value of field B.
The thing is, I don't want to write B's fields inside the A's serializer, as in the real life the structure is much more complicated and a class like A contains many other objects. So serializer should be able to delegate each object's writing to its own serializer.
Example:
public class AJsonSerializer extends JsonSerializer {
@OverRide
protected void doSerialize(JsonWriter writer, A value, JsonSerializationContext ctx, JsonSerializerParameters params) {
writer.beginObject();
writer.name("b");
// writer.value(value.getB()); <-- here I want to serialize B with its own custom serializer
writer.endObject();
}
}
Hello!
I our project repository we have thousands of classes, and not all were written conforming to the getter/setter patterns. This was not even required or necessary.
However, gwt-jackson by default processes such non-getter methods that start with "get***". As many such methods are not meant to be used outside of their contexts, they generate an error when called by gwt-jackson.
I know about @JsonAutoDetect. But I don't want to write annotations (or use mixin annotations) for 1000 classes!
Is there a way, to globally configure gwt-jackson for all types, to NEVER process getters and setters, and ONLY use fields?
