java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method
提问by pise
I have developed a web service with authentication in java following the link Web Service AtuthenticationThe Same is runing fine if I am using JDK 1.6/JBoss 4.2 but when I deploy it in Jboss 5.1.0 GA I am getting deployment error. I google and found there is some jar conflict between JDK1.6,Jboss and my application. And replaced the JBoss/lib/endorsed jaxws-ri.jar with the latest jaxws-ri-2.2.8.jar. But I am not able to identify which jar is creating conflict now.
我已经开发了一个带有 Java 身份验证的 Web 服务，链接Web 服务认证如果我使用的是 JDK 1.6/JBoss 4.2，则运行正常，但是当我在 Jboss 5.1.0 GA 中部署它时，出现部署错误。我google了一下，发现JDK1.6，Jboss和我的应用程序之间存在一些jar冲突。并将 JBoss/lib/endorsed jaxws-ri.jar 替换为最新的 jaxws-ri-2.2.8.jar。但是我现在无法确定哪个 jar 正在产生冲突。
Below is my code of web.xml, sun-jaxws.xml and exception.

java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "com.sun.xml.ws.util.xml.XMLStreamReaderFilter.getAttributeName(I)Ljavax/xml/namespace/QName;" the class loader (instance of org/jboss/classloader/spi/base/BaseClassLoader) of the current class, com/sun/xml/ws/util/xml/XMLStreamReaderFilter, and the class loader (instance of <bootloader>) for interface javax/xml/stream/XMLStreamReader have different Class objects for the type javax/xml/namespace/QName used in the signature
Thanks Pise
谢谢皮斯

The exception is thrown because in your web application at least exists a jar which contains the javax.xml.namespace.QNameclass and that class conflicts with the same one contained in one of the JBoss's jar.
抛出异常是因为在您的 Web 应用程序中至少存在一个包含javax.xml.namespace.QName该类的 jar，并且该类与 JBoss 的 jar 之一中包含的同一个冲突。
You should remove that (these) jar(s) from your web application when deploying on JBoss.
在 JBoss 上部署时，您应该从 Web 应用程序中删除（这些）jar。
A list of jars which contain the javax.xml.namespace.QNameclass is at http://www.findjar.com/class/javax/xml/namespace/QName.html
包含javax.xml.namespace.QName该类的 jar 列表位于http://www.findjar.com/class/javax/xml/namespace/QName.html
