Question

我正在运行一个用java编写的程序，部署在Oracle应用服务器上，运行1.5 JVM。以下是堆栈跟踪：

Exception in thread "main" java.lang.NoSuchMethodError: com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.getNamespaceContext()Lcom/sun/org/apache/xerces/internal/xni/NamespaceContext;

Process exited.

如果我使用jdk 1.6运行完全相同的程序，程序运行完美。这是库引用的特定问题吗？有人看过这个例外吗？

欢呼声。

我敢打赌，您的应用程序或Oracle AppServer附带的Xerces实现与JDK附带的Xerces实现之间存在冲突。

它适用于JDK6中的那个，但与JDK 5中的不兼容。

在使用jdk 1.5但不使用1.6时运行getNamespaceContext（）获取NoSuchMethodError
