我使用Netbeans 8.1，MySQL Server，Glassfish 4.1，Eclipselink作为JPA-provider，Jersey作为JAX-RS提供程序，并尝试部署以下简单程序：
该项目建立得很好。但是当尝试将ear文件部署到Glassfish 4.1 Application Server时，我在控制台中收到以下错误消息：
GlassFish Server 4.1, deploy, Can not read HTTP response, caught IOException, false
/Users/nicolas/Workspace (Java)/TestProject/nbproject/build-impl.xml:332: The module has not been deployed.
See the server log for details.
在Glassfish日志中，我阅读了以下内容：
Exception while preparing the app : Unable to load the EJB module. DeploymentContext does not contain any EJB. Check the archive to ensure correct packaging for /Users/nicolas/Workspace (Java)/OilImperium/dist/gfdeploy/TestProject/TestProject-war_war. If you use EJB component annotations to define the EJB, and an ejb or web deployment descriptor is also used, please make sure that the deployment descriptor references a Java EE 5 or higher version schema, and that the metadata-complete attribute is not set to true, so the component annotations can be processed as expected java.lang.RuntimeException: Unable to load the EJB module.

此外，战争项目似乎找不到@Entity类：
Class [ ch/baumgardt/model/Well ] not found. Error while loading [ class service.WellFacadeREST ]
......等等：
Class [ ch/baumgardt/model/Player ] not found. Error while loading [ class service.PlayerFacadeREST ]
有人有什么想法我可能做错了吗？
答案 0 :(得分：1)
可能是您的服务器无法访问netbeans。使用.war文件进行测试，看看服务器是否也出错了。

重新启动Glassfish并清理war和WEB_INF / lib文件夹，这是因为它发生了一段时间。 `Please Check out 或者你可以在netbeans的帮助下创建Restful webservices。 然后创建一个java包 右键单击CustomerDB节点，然后选择New＆gt;其他＆gt; Web服务＆gt;来自数据库的RESTful Web服务。将在“数据库表”面板上打开“新建RESTful Web服务”向导。 我希望它的帮助
