問題一旦將jsf 1.2遷移到jsf 2.2.12

Question

我正在將項目從jsf 1.2遷移到jsf 2.2.12。 構建成功后，我部署到jboss 7服務器，並收到如下錯誤消息：

您對此有任何想法嗎？

這是我的系統詳細信息：服務器：jboss7當前庫：jsf 1.2，richfaces 3.3.3遷移庫：jsf 2.2.17構建：maven

最好的祝福，

由以下原因導致：java.lang.LinkageError：接口可迭代初始化中的加載程序約束違規：當解析方法“ javax.faces.webapp.UIComponentClassicTagBase.getParent（）Ljavax / servlet / jsp / tagext / Tag;”時 當前類org / richfaces / taglib / ColumnsTag的類加載器（org / jboss / modules / ModuleClassLoader的實例）和接口javax / servlet / jsp /的類加載器（org / jboss / modules / ModuleClassLoader的實例） tagext / Tag對於ervlet / jsp / tagext / Tag類型具有不同的Class對象； 用於簽名

java.lang.LinkageError是帶有多個不同版本庫的類路徑污染的標志。 您最好讓Maven生成WAR文件，然后檢查其/WEB-INF/lib中是否存在不屬於該文件的任何庫（即，目標服務器已經提供的庫，例如Java EE，JSP ，Servlet，JSF等）。 然后相應地修復Maven pom.xml ，以准確標記provided 。

您獲得的特定建議建議使用重復的javax.servlet.jsp.* API。 您將在/WEB-INF/lib很可能有一個jsp-api.jar或另一個涵蓋此內容的JAR（例如javaee.jar ）。 在這種情況下，您需要按provided那樣在pom.xml准確標記該依賴項。 或者，如果它實際上是jsp-api ，則將其完全刪除，並使用具有版本6.0和所provided范圍的單個javaee-api或javaee-web-api依賴項，它已經完全覆蓋了整個Java EE 6（Web配置文件）由JBoss AS 7。
