当 SOAP 主体包含 UTF-8 BOM 时出现 JAX-WS 错误

Question

我使用部署在 WebLogic 10.3 上的 JAX-WS (v2.1.3 - Sun JDK 1.6.0_05) 开发了一个 Web 服务，当我使用 Java 客户端或 SoapUI 或其他 Web 服务测试工具时，它工作得很好。我需要使用 2005 Microsoft SQL Server Reporting Services 使用此服务，但出现以下错误

由于异常，无法创建 SOAP 消息：XML 阅读器错误：意外的字符内容

如果我使用 HTTP 代理来嗅探 SSRS 发送到 JAX-WS 的内容，我会看到 EF BB BF 作为帖子正文的开头，而 JAX-WS 不喜欢那样。如果我删除特殊字符并使用 Fiddler 重新提交请求，则 Web 服务调用有效。

为什么 JAX-WS 会因标准的 UTF-8 BOM 而崩溃？有没有解决方法来解决这个问题？任何建议将不胜感激。谢谢

一种解决方法的想法是：在将请求文档传递到 JAX-WS 服务之前，在仅使用 BOM 的 Web 应用程序上添加过滤器。
