How to get virtual document with DFS

tvv2000

Hi All.

I have virtual document and trying to get its content with descendants but without success. I experimented with RelationshipProfile, I have tried to set different options. What kind of options should I use for this purpose?

It is an example from my code. I set identities with one value - object identity of virtual document. May be I should pass identities for all documents that are in virtual document - I do not know.... I did not find any example how to handle virtual documents in DFS.

    public DataPackage download(ObjectIdentitySet identities) throws ServiceException {
        OperationOptions options = new OperationOptions();
        ContentProfile contentProfile = options.getContentProfile();
        contentProfile.setFormatFilter(FormatFilter.ANY);
        contentProfile.setPageFilter(PageFilter.ANY);
        options.setContentProfile(contentProfile);
        PropertyProfile propertyProfile = options.getPropertyProfile();
        propertyProfile.setFilterMode(PropertyFilterMode.SPECIFIED_BY_INCLUDE);
        propertyProfile.setIncludeProperties(ResourceObject.PROPERTIES);
        options.getContentTransferProfile().setTransferMode(ContentTransferMode.MTOM);

        RelationshipProfile relationProfile = new RelationshipProfile();
        relationProfile.setResultDataMode(ResultDataMode.OBJECT);
        relationProfile.setDepthFilter(DepthFilter.UNLIMITED);
        options.setRelationshipProfile(relationProfile);

return getFactory().getService(IObjectService.class).get(identities, options);
}

Thanks

Have you tried using the VirtualDocumentService? That's what it's for.

You do not set correctly RelationshipProfile. By default RelationshipNameFilter in RelationshipProfile = NONE, so no relations will be returned even if you set the DephFilter.

To retrieve a VirtualDocument from CS you have to provide the identity of the root and next RelationshipProfile

            RelationshipProfile relProfile = new RelationshipProfile(
                    ResultDataMode.OBJECT,
                    RelationshipNameFilter.SPECIFIED, Relationship.VIRTUAL_DOCUMENT_RELATIONSHIP,
                    TargetRoleFilter.SPECIFIED, Relationship.ROLE_CHILD,

DepthFilter.UNLIMITED, 0); //the integer does not play any role. it is taken into acount only when DepthFilter.SPECIFIED

You can use also VirtualDocumentService.retrieve() (since D6.5) if you do not pass an RelationshipProfile retrieve will set the profile like in the above example by itself.

You could also look at VdmRetrieveProfile if you need more options on retrieving the virtual document.

Hi Burlacu_Dorin

I do not know may be there are some problems on our server but I am getting an error with such usage of RelationshipProfile or may be I do not use ContentProfile correctly.... I am not sure. When I changed ResultDataMode to ResultDataMode.REFERENCE I could receive child document successfully, but with ResultDataMode.OBJECT I get an error

com.emc.documentum.fs.services.core.CoreServiceException: Operation output generation failed: could not retrieve data for identity: 090004d280028583.

Could yo help me with this error?

Thanks,

You probably did not set up correctly the ContentProfile.

You have to use PageFilter.ANY for getting all the content or PageFilter.NONE if you do not want content.

For more info I need the code, but as exception sayed you tried to retrieve a content for page 0 for an object that does not have content.

The code for download I sent before, I set up ContentProfile as

ContentProfile contentProfile = options.getContentProfile();
contentProfile.setFormatFilter(FormatFilter.ANY);
contentProfile.setPageFilter(PageFilter.ANY);
options.setContentProfile(contentProfile);

I think I set content profile properly, also I know that downloaded file has content, I could export virtual document via DAM. I do know whta is wrong. May be there is a problem with DFS version that I am using (6.0_SP1). In any case, thanks for your answer with RelationshipProfile
