您好，我正在尝试从 Ant 运行一个简单的基于 jax-ws soap/wsdl 的 Web 服务。如果我使用纯“java”从命令行运行程序，程序运行良好。 Ant 爆炸了。我在 Windows 7 32 位操作系统上使用 JDK jdk1.6.0.26 32 位。我的 Ant 是 1.7.1。

这是构建文件

最佳答案

org.apache.xerces.jaxp.datatype.DatatypeFactoryImpl 不在您的类路径中。 java 6 jvm 确实包含一个嵌入在 rt.jar 中的 Xerces 实现，但包名称不同 - 它是:com.sun.org.apache.xerces.internal.jaxp.datatype

您可以在代码中更改预期的 DatatypeFactoryImpl 或通过将单独的 Xerces jar 添加到类路径来覆盖 Xerces 实现。要覆盖 jvm 使用的类，您可以将任何版本的 xerces.jar 添加到 JVm 安装/lib/endorsed 目录。
