在 WebSphere AS 8.5 上部署 JAX-WS Web 服务时出错

Question

我正在尝试在安装在 *nix 操作系统上的 WAS 8.5 服务器上部署 JAX-WS Web 服务。 我收到以下错误：

[3/1/13 15:31:19:687 CET] 000003c0 WSServerMetad E   WSWS7055E: The WEB-INF/wsdl/KeyPushTargetService.wsdl Web Services Description Language (WSDL) file specified by annotations in class com.cryptomathic.ckms.KeyPushTargetServiceSoapImpl cannot be loaded correctly due to the following error: java.lang.RuntimeException: WSWS7035E: The http://www.w3.org/2001/XMLSchema.dtd metadata file could not be found.

WAS 是否真的试图下载 DTD frow W3C 服务器但未能做到这一点？ 我无法直接访问服务器机器，所以我无法直接验证它（但我可以问）。 我们在 Windows 系统上的 WAS 7.0 和 WAS 8.5 上成功部署了相同的 JAX-WS Web 服务（我们确信 WAS 在 Windows 服务器上部署时不会尝试从 Internet 下载任何 DTD）。

有什么想法吗？

谢谢， 乔瓦尼

Answer 1

我不知道具体的答案，但我有几个想法可以贡献。

您是否将您在 Windows 上部署的 EAR/WAR 与您在 *nix 安装上部署的 EAR/WAR 进行了比较？我假设它们是相同的，但我要检查该错误的第一件事是确保 WEB-INF/wsdl/KeyPushTargetService.wsdl 存在于您的部署工件中。

如果 WAS 试图下载 XMLSchema 定义，我会觉得很奇怪。这可能表明服务器存在一些配置问题。如果您想对此进行测试，您可以尝试创建另一个基本的 JAX-WS 服务（如 HelloWorld 示例）来部署并查看是否遇到相同的问题。

作为最后的手段，您也可以尝试将 DTD 放入您的 EAR/WAR 中，看看是否可以解决问题。我不会使用这个永久修复，但它可能会让你暂时移动。

让我知道这些是否可行。

检查您的运行时 jar 以获取 xml 解析器 - 看起来您遇到了类路径问题。
