无法部署 restful 应用程序自由配置文件 8.2

Question

我正在尝试在 liberty profile 8.5.5.2 上部署 RESTful 网络服务。我在服务器中启用了 jaxrs-1.1 功能，我正在使用 Java 1.7。当我启动服务器时，出现以下错误：

[ERROR   ] Uncaught.init.exception.thrown.by.servlet

以下是我的 web.xml 文件中的条目：

<servlet>
        <servlet-name>JAX-RS Servlet</servlet-name>
        <servlet-class>org.apache.wink.server.internal.servlet.RestServlet</servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.example.RestfulResourceLoader</param-value>
        </init-param>
        <init-param>
        <param-name>propertiesLocation</param-name>
        <param-value>mobilehandler.properties</param-value>
     </init-param>
     <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>JAX-RS Servlet</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>

我还需要执行哪些其他配置才能消除此错误？

WebSphere Liberty 支持 JAX-RS 1.1，因此您无需提供 servlet class，只需使用 web.xml 中的以下片段：

<servlet>
    <servlet-name>javax.ws.rs.core.Application</servlet-name>
</servlet>
<servlet-mapping>
    <servlet-name>javax.ws.rs.core.Application</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

另请参阅：

Configuring JAX-RS applications using JAX-RS 1.1 methods

更新

HandlersFactory 来自第三方库，请尝试将以下 classloader（在 server.xml 中）添加到您的应用程序以使库可见。

<webApplication... >
    <classloader apiTypeVisibility="spec,ibm-api,api,third-party">
    </classloader>
</webApplication>
