Liferay中的java.lang.ClassNotFoundException：com.liferay.portal.jsonwebservice.JSONWebServiceServlet？

hai iam新增json Web服務liferay中出現以下錯誤！我已經在web.xml中添加了JSONWebServiceServlet。我必須將任何jar文件添加到類路徑嗎？Liferay中的java.lang.ClassNotFoundException：com.liferay.portal.jsonwebservice.JSONWebServiceServlet？

在web.xml中我已經這樣寫的：

<?xml version="1.0" encoding="UTF-8"?>

我有同樣的問題，當我加在web.xml中相關代碼的JSON Web服務。之後，我得到了同樣的錯誤...如果你找到任何解決方案，然後請張貼它 –
