java.lang.LinkageError: loader constraint violation previously initiated loading for a different type with name "javax/xml/soap/SOAPMessage"
提问by Joecep
I'm new to webservices. I'm trying to call a service but I'm having the below error. Based on my initial google search seems this is a loader issue that can be caused by duplicate jars, but I cannot locate which one causes this. Any help is very much appreciated.
我是网络服务的新手。我正在尝试调用服务，但出现以下错误。根据我最初的谷歌搜索，这似乎是一个加载器问题，可能是由重复的 jars 引起的，但我无法找到是哪个导致了这个问题。很感谢任何形式的帮助。

LinkageError is JBoss is generally caused by your app packaging its own copies of certain libraries that JBoss considers restricted. These are usually things in the java.* and javax.* packages.
LinkageError 是 JBoss 通常是由您的应用程序打包 JBoss 认为受限的某些库的自己的副本引起的。这些通常在 java.* 和 javax.* 包中。
Try adding cxf-rt-frontend-jaxws and cxf-bundle-rs as dependencies and mark some exclusions -> jetty-server, gernomino-servlet.
尝试添加 cxf-rt-frontend-jaxws 和 cxf-bundle-rs 作为依赖项并标记一些排除项 -> jetty-server, gernomino-servlet。
Also check the beans.xml is expected to be under the classpath, instead of WEB-INF.
还要检查 beans.xml 是否应该在 classpath 下，而不是 WEB-INF。
