Java &引用；出现重复的类定义错误"；在jboss中使用jaxb

我在jboss 5.0.1GA容器中使用jaxb，在启动时看到一个奇怪的异常。它只出现一次

从stacktrace中，您可以看到它正在FrameworkUtil类的类初始化期间

FrameworkUtil第119行如下所示：

JAXBContext j = JAXBContext.newInstance(Validate.class, Response.class ....<more classes>);

你退房了吗？ 在jaxb实现的版本2.2.11中似乎已修复

也许您可以尝试替换jaxb JAR文件，它们可能在您服务器的lib中，除非您的webapp在自己的lib文件夹中覆盖它们

<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.2.11</version>
</dependency>

com.sun.xml.bind
jaxb impl
2.2.11

Hi，是的，我看到了这个-它说它在2.2.2中修复了。尽管我们在构建中使用的是JAXB2.2.7，但jboss运行的是2.1.9，所以这可能是原因所在。
