Question

我使用马文、泽西和杰蒂服务器建立一个网络服务界面

当我在日光上开发和测试软件时,一切都很好。然而,当我试图部署项目并向接口提出请求时,服务器报告说,“找不到MIME媒体类型应用程序/xml”。

我试图在几天内找出问题,发现(由泽西岛提供的)ServiceFinder(由泽西岛提供)可以在Eclipse上找到所有信件BodyWriter, 但不在命令线上。我还检查了所有热量自由已经到位, 并在META- INF 中定义。

任何帮助都是感激不尽的!

JDK: 1.6.0_30 Eclipse: Indigo SR2 Jersey: 1.12 Jetty: 6.1.25

服务源代码 :

ServiceFinder.find(javax.ws.rs.ext.MessageBodyWriter.class, true).toClassArray();

=============== META-INF Created-By: Apache Maven Built-By: Build-Jdk: 1.6.0_30 Class-Path: jersey-servlet-1.12.jar jersey-server-1.12.jar asm-3.1.jar jersey-core-1.12.jar

在命令行( 仅可查看MessageBodyWriter 可用)

============= Start Jetty Server ==== I am using Jetty Web Server, and started the server like this:

Context root = new Context(server, "/", Context.SESSIONS); 
// Add REST handlers and Singleton providers 
ResourceConfig rc = new PackagesResourceConfig("handlerpkg"); 

// Add the Jersey root servlet holder to the root context 
root.addServlet(new ServletHolder(new ServletContainer(rc)), "/*");

server.start();

这个问题的解决方式是,在舱道中明确增加球衣核心-1.12.jar,作为VM论点的一部分。

我当时只有一个图书馆在 - cp 中, 它指向使用 ANIFEST. MF 文件中的类Paths 字段的其他图书馆。有趣的是, 使用这个方法, 服务员可以找到 messageBodyReader, 但不能找到 MessageBodyWriter 。

现在,我有两个图书馆在 -cp, 这是球衣核心-1.12jar 和 lib 包含主班。
