我正在尝试开发一个简单的 Java 程序来调用 DFS Web 服务，但我得到了这个运行时错误：
Caused by: com.emc.documentum.fs.rt.impl.servicemodel.ServiceModelException: Service descriptor class not found: "java.lang.ClassNotFoundException: com.emc.documentum.fs.services.core.client.ObjectServiceDescriptor".
at com.emc.documentum.fs.rt.impl.servicemodel.JavaBeanTreeFactory.getDescriptor(JavaBeanTreeFactory.java:218)

我正在使用maven构建一个项目并将其安装到Adobe CQ5 的 OSGi 容器中。我在 Eclipse 中的一个普通 Java 应用程序中尝试了相同的代码，它工作正常。
对我来说奇怪的是，这个类 ObjectServiceDescriptor 位于我通过 maven 依赖项包含的 .jar 库之一中。jar 名称是emc-dfs-services-remote-1.0.jar。如果我打开 maven 生成的 .jar，我可以在那里看到emc-dfs-services-remote-1.0.jar。
项目编译没有任何问题，但在运行时我在这一行得到错误：
IObjectService objectService = serviceFactory.getRemoteService(com.emc.documentum.fs.services.core.client.IObjectService.class, serviceContext, module, host);
我的 pom.xml 在下面。如您所见，我在 Imported-Packages 中将一些包声明为可选。如果我不这样做，我的包可以编译，但无法启动。将这些包声明为可选包会是问题吗？

ContextFactory contextFactory = ContextFactory.getInstance();
serviceContext = contextFactory.newContext();
RepositoryIdentity repositoryIdentity = new RepositoryIdentity();
repositoryIdentity.setRepositoryName(repository);
repositoryIdentity.setUserName(user);
repositoryIdentity.setPassword(pass);
serviceContext.addIdentity(repositoryIdentity);
ServiceFactory serviceFactory = ServiceFactory.getInstance();
//ERROR is thrown here:
objectService = serviceFactory.getRemoteService(IObjectService.class, serviceContext, module, host);
queryService = serviceFactory.getRemoteService(IQueryService.class, serviceContext, module, host);
}
我在这里看到了类似的问题：https ://community.emc.com/thread/82798但那里提供的解决方案对我没有帮助。我试过了
- 将 JRE 版本更改为高于 1.5
- 确保我正在创建一个类型为 com.emc.documentum.fs.services.core.client.IObjectService 的类（而不是 com.emc.documentum.fs.services.core.impl.IObjectService）。
- 尝试使用更完全参数化的 getRemoteService 版本，这将消除调用中的任何歧义。
- 还有很多其他的事情，比如将所有外部 jar 安装在一个单独的包中，然后导入它们。
它看起来像一个 maven 依赖问题，但我无法弄清楚，因为我在我的项目中包含了我在 Eclipse 项目中使用的所有 .jar，所以它应该工作相同，不是吗？
我很感激任何帮助。
编辑：我尝试将导出包更改为：info.hartmann.dfs.api, com.emc.documentum.* 换句话说，我尝试导出所有文档包。上面列出的错误消失了，但我得到了一个新错误：
Caused by: com.emc.documentum.fs.rt.impl.servicemodel.ServiceModelException: Service descriptor file not found: "services-core-service-model.xml".

不幸的是，我什至不知道它是让我更进一步还是落后一步。
