我使用过的JARS以下

cxf-core-3.1.6.jar

cxf-rt-frontend-jaxrs-3.1.6.jar

cxf-rt-transports-http-3.1.6.jar

javax.ws.rs-api-2.0.1.jar

 <servlet>
        <servlet-name>CXFServlet</servlet-name>
        <servlet-class>org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet</servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.ibm.services.rest.Echo</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>

谁能帮我解决这个问题。我正在使用CXF 3.16，WAS 8.5，JDK 1.7。 WoodstoxValidationImpl在cxf核心jar中可用，但不要为什么我会收到此错误

您可能想要与CXF users mailing list进行核对，以查看社区之前是否已看到此内容，或打开JIRA issue。简而言之，我看不到WoodstoxValidationImpl类如何无法初始化-它的构造函数包括处理所有Throwable的try / catch块。希望CXF社区能够提供更多帮助。

我建议您升级到WebSphere v9或WebSphere Liberty，然后再深入研究。 WebSphere v8.5随JAX-RS 1.1 API一起提供，并且没有“关闭它们”的方法，因此，能够从应用程序的jar中加载JAX-RS 2.0 API的唯一方法是使用父类-last classloading（或其他此类classhacks）。 WAS v9和Liberty都提供2.0（并且Liberty也提供2.1）API，但是更重要的是，它们都允许您根据需要禁用API。同样，FWIW，WAS v9和Liberty都使用CXF作为底层JAX-RS实现，因此您可以使用更薄的WAR并仍然获得所需的JAX-RS实现。

HTH，安迪
