NullPointerException jaxb.Utils.getFieldXJTA（Utils.java:269）(NullPointerException jaxb.Utils.getFieldXJTA(Utils.java:269))

错误：

谷歌搜索导致没有任何帮助解决这个错误。 该代码在IDE中完美工作。 在部署为使用在Jboss上运行的LiveCycle的自定义组件时发生此错误。

相关的问答让我意识到了这一点：

Googling resulted in nothing helpful to resolve this error. The code works perfectly within in the IDE. This error occurs when deployed as a Custom Component withing LiveCycle that is running on Jboss.

最满意答案

我遇到了同样的问题，使用自定义ClassLoader，原因似乎是缺少为类定义的“包”。 我纠正了为加载类定义包的ClassLoader实现，并且都开始为我正常工作。

简而言之，NullPointerException是通过调用f.getDeclaringClass().getPackage().getAnnotation(XmlJavaTypeAdapters.class); 。 在我的情况下， f.getDeclaringClass().getPackage()返回null。

我不知道这是否会帮助其他人，但我在我的特殊情况下工作，我决定分享这个。

我忘了发布源参考：

http://grepcode.com/file/repo1.maven.org/maven2/org.apache.cxf/cxf-rt-databinding-jaxb/3.1.1/org/apache/cxf/jaxb/Utils.java#269

I had the same problem, working with custom ClassLoader and the reason appeared to be the lack of a "Package" defined for classes. I corrected the ClassLoader implementation defining packages for loaded classes and all started to work fine for me.

In a few words, the NullPointerException was generated by the call to f.getDeclaringClass().getPackage().getAnnotation(XmlJavaTypeAdapters.class);. In my case f.getDeclaringClass().getPackage() returned null.

I don't know if this will help someone else, but I got it working in my very special case and I decided to share this.

I forgot to post a source reference:
