Java EE / OmniFaces：项目设置 - 使用WildFly的LinkageError

标签： java-ee jboss wildfly omnifaces

尝试将OmniFaces集成到Java EE Web项目中。

实现以下简单侦听器方法时，我收到链接错误。我正在使用WebSphere应用程序服务器。

这里发生了什么？

public void useCreditCardChanged(javax.faces.event.ValueChangeEvent event) {
    Boolean oldVal = (Boolean) event.getOldValue();
    Boolean newVal = (Boolean) event.getNewValue();
    if (oldVal!=null) {
        this.useCreditCard = newVal;
    }
    FacesContext.getCurrentInstance().renderResponse();
}

和日志文件：

引起：java.lang.RuntimeException：java.lang.RuntimeException：java.lang.LinkageError：接口itable初始化中的加载器约束违规：解析方法时“org.omnifaces.taghandler.ValidateUniqueColumn.processValueChange（Ljavax / faces / event / ValueChangeEvent;）V“当前类的类加载器（org / jboss / modules / ModuleClassLoader的实例），org / omnifaces / taghandler / ValidateUniqueColumn，以及类加载器（org / jboss / modules / ModuleClassLoader的实例）接口javax / faces / event / ValueChangeListener 具有不同的类对象（Ljavax / faces / event / ValueChangeEvent;）签名中使用的V

您在webapp的运行时类路径中有多个不同版本的JSF API类。在这个特殊问题中，特别是对于javax.faces.event.ValueChangeEvent类，在webapp的运行时类路径中找到了多个不同的版本。换句话说，webapp的运行时类路径是脏的。很可能你在webapp的/WEB-INF/lib中有不属于那里的JAR，因为appserver本身已经开箱即用，例如Java EE和JSF。

然后你的问题还有另外一件奇怪的事情。您正在谈论IBM WebSphere并且您已标记[websphere]，但堆栈跟踪中列出的appserver特定类清楚地告诉它是JBoss WildFly，这是一个完全不同的服务器，但也许解释了您添加[jboss]标记的原因。同样，这是两个完全不同的服务器。知道你在用什么。

无论如何，请浏览webapp的/WEB-INF/lib并删除已由应用服务器本身提供的库，例如javaee.jar，jsf-api.jar等。
