Question

我正在使用Hibernate，Spring和JSF开展Web项目。当我运行项目时，我得到以下异常：

Servlet.service() for servlet Faces Servlet threw exception
java.lang.UnsupportedOperationException
    at javax.faces.application.Application.getResourceHandler(Application.java:286)

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)

这是如何引起的？如何解决？

Answer 1

导致此问题是因为运行时类路径中缺少适用于JSF API的JSF实现。解决方案是将JSF实现JAR文件放在运行时类路径中。

换句话说，您有一个/WEB-INF/lib/jsf-api.jar文件，但不是/WEB-INF/lib/jsf-impl.jar文件，至少不是与JSF API JAR文件相同的版本。您需要确保提供一个，至少是正确的版本。

javax.faces.application.Application.getResourceHandler上的java.lang.UnsupportedOperationException
