Question

我在Websphere Application Server 7上部署了一个EAR。在我的代码中，我尝试将XML文件解组为一个对象。尝试这样做时出现此错误：

据我所知，该类是IBM JDK的一部分，在运行时无法找到。有什么我必须在我耳边修改，或者，我猜，它都是关于配置/修改WAS配置（如果这是一个错误，甚至应用补丁）。

有任何帮助吗？非常感谢。

（抱歉我的英文:)）

Answer 1

此异常表示找到了类com.ibm.xtq.bcel.util.SyntheticRepository，但静态初始化失败。如果日志中没有关于此的消息，那么现在是时候用IBM打开PMR了。内部WebSphere代码中的静态初始化程序在正常使用过程中永远不会失败。

Answer 2

同样，这里有一个APAR： http://www-01.ibm.com/support/docview.wss?uid=swg1IV41639

Problem conclusion
This defect will be fixed in:
6.0.0 SR14
6.0.1 SR6
7.0.0 SR5
.
The fix resolved the AccessControlException. SyntheticRepository
class can be initialized properly, hence NoClassDefFoundError
does not occur.

使用JAXB解组XML时，WebSphereApplication NoClassDefFoundError
