如何使用 Omnifaces 1.14.1 修复 javax.xml.xpath.XPathFactoryConfigurationException
How to fix javax.xml.xpath.XPathFactoryConfigurationException with Omnifaces 1.14.1
我们有一个 JSF 2.0 Web 应用程序，运行 在 WAS 8.5 上，我们在其中使用 Omnifaces FullAjaxExceptionHandlerFactory。剩下的应用程序中没有使用 Omnifaces 的任何其他内容。 UI 基于 Primefaces 框架。
应用程序正常启动但在某些操作（应用程序中的更改选项卡，按按钮）时出现以下异常：
000000d2 ServletWrappe E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: An exception was thrown by one of the service methods of the servlet [FacesServlet] in application [<anonymized>].

如果我注释掉 pom.xml 中的依赖项和 faces-config.xml 中的工厂。该应用程序运行良好。
这里是faces中的条目-config.xml

是否知道不兼容从何而来？
Is there any idea, from where the incompatibility comes from?
不兼容性来自您项目中的依赖项：
<dependency>
<groupId>net.sf.saxon</groupId>
<artifactId>Saxon-HE</artifactId>
<version>9.5.1-1</version>
</dependency>
Saxon-HE-9.5.1-1.jar 包含一项服务 /META-INF/services/javax.xml.xpath.XPathFactory，其中包含非法包含空格的行：
net.sf.saxon.xpath.XPathFactoryImpl
http\://java.sun.com/jaxp/xpath/dom: net.sf.saxon.xpath.XPathFactoryImpl
http\://saxon.sf.net/jaxp/xpath/om: net.sf.saxon.xpath.XPathFactoryImpl
这在 javax.xml.xpath.ServiceLoader.parseLine 方法中失败：
....
if ((ln.indexOf(' ') >= 0) || (ln.indexOf('\t') >= 0))
fail(service, u, lc, "Illegal configuration-file syntax");
....
尝试将您的 Saxon-HE 版本升级为 9.5.1-1 is rather old (2013) 并且似乎与 Java 8+ 不兼容。
版本 9.5.1-5 是 first version with this bug fixed。
The following bugs are cleared in 9.5.1.5, issued 2014-03-25
