我试图启动在WAS 8控制台中部署的应用程序。我见过类似这样的问题，但无法理解我必须实施的解决方案。请帮我解决一下这个。我坚持不懈。

答案 0 :(得分：0)
LinkageError通常表示一个类可以看到某个类的两个不同版本，一个直接（通过它自己的类加载器）和一个间接（通过一些其他加载器）。这通常只能通过父母最后一次加载来实现，所以如果您不需要，那么切换类加载模式可能会有所帮助。一般来说，如果你没有特定的理由使用＆＃34; parent last＆＃34;，那么应该避免它，因为它与默认的Java类加载行为混淆并且可能导致像这样的问题。< / p>
根据错误消息，我猜测duplicate-visibility类是javax.xml.namespace.QName类。您是否有理由在应用程序中打包XML API？ WAS有一个在其JDK中打包的Xerces副本，因此除非您对XML提供程序有一些特殊性，否则您实际上不太可能需要这样做。如果您确实需要＆＃34; parent last＆＃34;，删除包含XML API的jar也可能解决问题。
