在JBoss AS 7中找不到JAXB com.sun.xml.internal.bind.v2.ContextFactory类 [英] JAXB com.sun.xml.internal.bind.v2.ContextFactory Class Not Found in JBoss AS 7

问题描述

在JBoss中使用JAXB时，我在执行代码时遇到异常：

While using JAXB in JBoss, I am getting below exception while executing the code:

  JAXBContext   jaxbContext   = JAXBContext.newInstance( jaxbElement.getClass().getPackage().getName() );

我得到的例外情况是：

[java.lang.ClassNotFoundException: com.sun.xml.internal.bind.v2.ContextFactory from [Module "deployment.project.ear.subproject-jboss.jar:main" from Service Module Loader]]
    at javax.xml.bind.ContextFinder.newInstance(ContextFinder.java:156) [jboss-jaxb-api_2.2_spec-1.0.4.Final-redhat-3.jar:1.0.4.Final-redhat-3]
    at javax.xml.bind.ContextFinder.newInstance(ContextFinder.java:108) [jboss-jaxb-api_2.2_spec-1.0.4.Final-redhat-3.jar:1.0.4.Final-redhat-3]

看起来JBoss JAXB模块正在加载而不是JDK，这就是异常的原因，但我不是确定如何解决这个错误？

It looks like JBoss JAXB module is loading instead of JDK and this is the reason of exception, however I am not sure how to solve this error?

推荐答案

最后我通过将默认上下文工厂更改为eclipse链接上下文工厂来解决它，但不确定为什么它不适用于默认值。

Finally i solved it by changing default context factory to eclipse link context factory, but not sure why it does not worked with default one.

  JAXBContext jaxbContext = JAXBContextFactory.createContext(  clss.getPackage().getName() , clss.getClass().getClassLoader());

并导入 org.eclipse.persistence.jaxb.JAXBContextFactory class。
