Spring JsonProcessingExceptin NoClassDefFoundError за останал шаблон

Използвам парсер на jackson и той работи с моя шаблон за почивка, когато поиска получаване, но когато се опитам да направя публикация, ми дава следната грешка:

web.util.NestedServletException: 
Handler processing failed; 
nested exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/JsonProcessingException

Не знам какво се обърка. Опитвам се да изпратя заявка за публикация и нейното тяло трябва да е обект:

@RequestMapping(value = "dogCreated", method = RequestMethod.POST)
@ResponseStatus(HttpStatus.CREATED)
public String createDog(@ModelAttribute Dog dog, BindingResult result, Model model){
RestTemplate rest = new RestTemplate();
//      List< HttpMessageConverter<?> > messageConverters = new ArrayList< HttpMessageConverter<?> >();   
//      // empty list created
//
//      messageConverters.add( new MappingJackson2HttpMessageConverter() );      
//      messageConverters.add( new StringHttpMessageConverter() );

        rest.getMessageConverters().add(new MappingJackson2HttpMessageConverter());/*This is where the error occurs*/
        rest.getMessageConverters().add(new StringHttpMessageConverter());

        ObjectMapper mapper = new ObjectMapper();
        TypeFactory typeFactory = mapper.getTypeFactory();

        String response = rest.postForObject("https://rest-service.herokuapp.com/createDog", dog, String.class);
        System.out.println(response);

Включих и двете зависимости на Jackson в моя pom.xml:

<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-core-asl</artifactId>
    <version>1.9.13</version>
</dependency>
<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>1.9.13</version>
</dependency>

Може ли някой да ми каже къде бъркам? По-конкретно се казва, че грешката възниква на този ред:

rest.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

Всяка помощ ще бъде високо оценена.

Това е пълно проследяване на стека

Можете ли да добавите пълния стек - ще има основна причина за noclassdef - 6ton 18.07.2015

@6ton Добавих пълното проследяване на стека. Не знам дали това е твърде полезно. Ред 42 е редът, който маркирах, който причинява проследяването на стека. - beginnerCoder 18.07.2015

Проблемът, който имате, е, че използвате много стари зависимости, които последната пролет не поддържа:

<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-core-asl</artifactId>
    <version>1.9.13</version>
</dependency>
<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>1.9.13</version>
</dependency>

Тъй като горните библиотеки се промениха малко, трябва да премахнете тези зависимости и да поставите нова:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.5.4</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.5.4</version>
</dependency>

Променете това и вижте резултатите. Ако работи, направете това като отговора.

Благодаря, точно това ми липсваше!! - beginnerCoder; 19.07.2015

подобен проблем, използвам gradle: compile 'com.fasterxml.jackson.core:jackson-core:2.7.3' compile 'com.fasterxml.jackson.core:jackson-databind:2.7.3' - Yang; 20.04.2016
