I am trying to develop a simple java program that calls DFS web services and I get this runtime error:
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".

I'm using maven to build a project and to install it into the OSGi container of Adobe CQ5. I tried this same code in a usual Java application in Eclipse and it worked.
The strange thing for me is that this class ObjectServiceDescriptor is in one of the .jar libraries which I include through maven dependencies. The jar name is emc-dfs-services-remote-1.0.jar. If I open my .jar generated by maven, I can see the emc-dfs-services-remote-1.0.jar there.
The project compilation goes without any problems, but during runtime I get the error on this line:
IObjectService objectService = serviceFactory.getRemoteService(com.emc.documentum.fs.services.core.client.IObjectService.class, serviceContext, module, host);
My pom.xml is below. As you see, I declare some of the packages as optional in Imported-Packages. If I don't do this, my bundle can be compiled, but cannot be started. Could declaring these packages as optional be the problem?

My Java code:
public void init() throws Exception {
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);
}
I've seen a similar problem here: https://community.emc.com/thread/82798 but the solution provided there didn't help me. I tried
- Changing JRE version to higher than 1.5
- Making sure make sure that I am creating a class of type com.emc.documentum.fs.services.core.client.IObjectService (and not com.emc.documentum.fs.services.core.impl.IObjectService).
- Trying with the more fully parameterized version of getRemoteService which will remove any ambiguties with the call.
- And lots of other things, like installing all the external jars in a separate bundle and then importing them.
It looks like a maven dependency problem, but I can't figure it out, as I included all the .jars in my project which I used in my Eclipse project, so it should work the same, shouldn't it?
I appreciate any help.
EDIT: I tried changing export-packages to: info.hartmann.dfs.api, com.emc.documentum.* In other words, I tried exporting all the documentum packages. The above listed error dissapeared, but I got a new one:
Caused by: com.emc.documentum.fs.rt.impl.servicemodel.ServiceModelException: Service descriptor file not found: "services-core-service-model.xml".

Unfortunatelly, I don't even know if it moves me one step further or one step behind.
It looks like your user bundle is missing the wiring to
com.emc.documentum.fs.services.core.client.ObjectServiceDescriptor. Just being in the classpath is not enoughConfirm that the
JavaBeanTreeFactorybundle imports the packagecom.emc.documentum.fs.services.core.client
