Java 链接错误 JAX-WS

Question

我在尝试使用 Web 服务时收到此错误。我用谷歌搜索它，发现它发生是因为同一类文件的不同版本可能存在或者发生一些冲突。我尝试在运行 Web 应用程序时提供认可的目录路径，但仍然没有成功。我使用的环境是 JDK 1.6.0.20 和 JBoss 5.0。：

java.lang.LinkageError: loader constraint violation: when resolving method "javax.xml.ws.Service.<init>(Ljava/net/URL;Ljavax/xml/namespace/QName;)V" the class loader (instance of org/jboss/classloader/spi/base/BaseClassLoader) of the current class, com/abc/amservice/AMService, and the class loader (instance of <bootloader>) for resolved class, javax/xml/ws/Service, have different Class objects for the type javax/xml/namespace/QName used in the signature

Answer 1

可以在此问题中找到解决方案。

简而言之：确保您没有部署另一个 javax.xml.namespace.* 包，而是依赖 Java 6 附带的包

Answer 2

有两个选项可以帮助您：

1 - 在运行时更改 Jboss 版本。重新下载Jboss，你的版本就可以破解了，很常见的。因此，根据您的安装在 Eclipse 中设置 Jboss 运行时，如下所示：“C:\jboss-eap-5.1\jboss-as”。

或者

2 - 如果在您的情况下可行，只需删除构建路径中的 lib wsdl4j.jar 即可。
