Java 应用程序引擎上的Jersey设置

我最近将jersey添加到我的app engine项目中，在我的本地机器上一切都很好，但是当我尝试访问部署站点上的页面时，我会出错。我想我可能包含了一个不受支持的类，但我认为我没有使用任何类。我的大部分代码都是本安装指南的精确副本

这是我的密码：

@GET
@Path("/url")
public Response getCallbackUrl() {
  /* this is /_ah/upload and it redirects to its given path */
  String url = blobstoreService.createUploadUrl("/rest/file");
  return Response.ok(new FileUrl(url), MediaType.APPLICATION_JSON).build();
}

web.xml：

<servlet>
    <servlet-name>jersey</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.config.property.packages</param-name>
        <param-value>com.thedailycaption</param-value>
    </init-param>
    <init-param>
           <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
         <param-value>true</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>jersey</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

以下是我得到的错误：

Uncaught exception from servlet

以下是启动时的错误：

您需要添加

<init-param>
    <param-name>com.sun.jersey.config.feature.DisableWADL</param-name>
    <param-value>true</param-value>
</init-param>

到web.xml

这将阻止使用反射的类，这在应用程序引擎上是不允许的

你能发布你的web.xml让我们看到jersey servlet映射吗？你能发布你的web.xml让我们看到jersey servlet映射吗？
