XIncludeAwareParserConfiguration 与 XMLParserConfiguration 不兼容

Question

在 AIX 平台上将 Ear 文件部署到 WLS 10.3 时出现此错误。同一只耳朵在 Windows/Linux 平台上运行良好。

您的类路径可能挤满了 Xerces API 的不同版本的 JAR 文件。清理类路径。对于 Web 应用程序，这包括 Webapp/WEB-INF/lib、Appserver/lib 和 /JRE/lib 文件夹。

最常见的原因是您有不同版本的 Xerces JAR 分布在 Webapp/WEB-INF/lib 和 Appserver/lib 上。假设应用程序服务器库中的版本是默认提供的正确版本，请删除 web 应用程序库中的版本。 Web 应用程序的库中不应有任何特定于应用程序服务器的 JAR。
