は私のコードですstruts.xml

<struts> 
    <constant name="struts.devMode" value="true"></constant> 
    <constant name="struts.custom.i18n.resources" value="resources.myvalidation"></constant> 
<package name="mypackage" namespace="/" extends="struts-default, json-default, action-default"> 
    <result-types> 
       <result-type name="json" class="org.apache.struts2.json.JSONResult" default="true"/> 
       <result-type name="dispatcher" class="org.apache.struts2.dispatcher.ServletDispatcherResult" default="true"/> 
      </result-types> 
<action name="misinfo" class="com.dao.impl.JsonActionDaoImpl"> 
     <result name="success">/WEB-INF/jsp/mis.jsp</result> 
     <result name="input">/WEB-INF/jsp/mis.jsp</result> 
     </action> 
     <action name="jsontable" class="com.dao.impl.JsonActionDaoImpl"> 
     <result name="success">/WEB-INF/jsp/mis.jsp</result> 
     </action> 
</package> 
</struts> 

と私はWEB-INF/libフォルダの下のStruts2の-JSON-プラグイン-2.3.8-sources.jarを含むすべての必要なライブラリを持っています。

Answer 1

ファイル：struts2-json-plugin-2.3.8-sources.jarにはJavaファイルしか含まれていません。実行時には不要です。 struts2-json-plugin-2.3.8.jarのバイナリを含めて、例外はなくなります。
