我最近添加澤西到我的應用程序引擎項目，一切工作在我的本地機器很好，但是當我嘗試訪問部署的網站上的頁面時，我收到錯誤。我想我可能會包括一個不受支持的類，但我認爲我沒有使用任何類。我的大部分代碼是從本指南的精確副本設置jQuery upload澤西安裝在應用程序引擎
這裏是我的代碼：
@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();
}
的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>
這裏是我得到的錯誤：
