问题一旦将jsf 1.2迁移到jsf 2.2.12

Question

我正在将项目从jsf 1.2迁移到jsf 2.2.12。 构建成功后，我部署到jboss 7服务器，并收到如下错误消息：

您对此有任何想法吗？

这是我的系统详细信息：服务器：jboss7当前库：jsf 1.2，richfaces 3.3.3迁移库：jsf 2.2.17构建：maven

最好的祝福，

由以下原因导致：java.lang.LinkageError：接口可迭代初始化中的加载程序约束违规：当解析方法“ javax.faces.webapp.UIComponentClassicTagBase.getParent（）Ljavax / servlet / jsp / tagext / Tag;”时 当前类org / richfaces / taglib / ColumnsTag的类加载器（org / jboss / modules / ModuleClassLoader的实例）和接口javax / servlet / jsp /的类加载器（org / jboss / modules / ModuleClassLoader的实例） tagext / Tag对于ervlet / jsp / tagext / Tag类型具有不同的Class对象； 用于签名

java.lang.LinkageError是带有多个不同版本库的类路径污染的标志。 您最好让Maven生成WAR文件，然后检查其/WEB-INF/lib中是否存在不属于该文件的任何库（即，目标服务器已经提供的库，例如Java EE，JSP ，Servlet，JSF等）。 然后相应地修复Maven pom.xml ，以准确标记provided 。

您获得的特定建议建议使用重复的javax.servlet.jsp.* API。 您将在/WEB-INF/lib很可能有一个jsp-api.jar或另一个涵盖此内容的JAR（例如javaee.jar ）。 在这种情况下，您需要按provided那样在pom.xml准确标记该依赖项。 或者，如果它实际上是jsp-api ，则将其完全删除，并使用具有版本6.0和所provided范围的单个javaee-api或javaee-web-api依赖项，它已经完全覆盖了整个Java EE 6（Web配置文件）由JBoss AS 7。
