Я использую struts 2 json plugin для использования автозаполнения. У меня написать действие,struts 2 json плагин вызывает ошибку, не задан тип результата

в struts.xml

<package name="example" extends="json-default"> 

    <result-types> 
     <result-type name="json" class="com.googlecode.jsonplugin.JSONResult"/> 
    </result-types> 

     <action name="searchIndustryaction" class="com.sample.action.GetStartedAction" method="searchIndustry"> 
     <result name="success" type="json"></result> 
     </action> 

    </package>

появляется сообщение об ошибке в ответ, когда я вижу через поджигатель

отметьте его как ответ, если у вас есть решение :) – PSR

это json, результат которого мне нужно указать – jackyesind

+0

в классе действий, который вы сохранили в переменной. Это правильно? – PSR

Вы получаете исключение проверки или тип преобразования, поэтому он ищет "input" результата.

Исправить исключение для проверки подлинности/преобразования типов.

Я пропустил проверку, но я получил ошибку java.lang.NoClassDefFoundError: Не удалось инициализировать класс org.apache.struts2.json.JSONResult – jackyesind

+0

@jackyesind Тогда вы неправильно развертываете плагин JSON или одну из его зависимостей. –

+0

Я включил файл struts2-json-plugin-2.1.8.1.jar в папку lib и добавил jar в путь построения – jackyesind
