Hey Florian, Repository is using 1.1 version (I noticed from the given URL and workbench) ; from the Workbench I can inspect the object, get all extra properties and use the Content URL Link to download it.
So a quick solution is instead of using the GetObject/GetContentstream is using the https:// link with cmis:name/objectid and .Net webclient to download it, or is there another (more neat) way with CMIS client to do this ? I'm not a Java person that's why i chose the DotCmis version :-) regards, Erwin -----Oorspronkelijk bericht----- Van: Florian Müller [mailto:f...@apache.org] Verzonden: zaterdag 6 september 2014 10:10 Aan: dev@chemistry.apache.org CC: Erwin Moll - Nazca-I Onderwerp: Re: I: problem with getting contentstream of object Hi Erwin, Which repository are you connected to and which CMIS binding are you using? You get a "Property 'gu:letterCharacteristic' doesn't exist!" error message if either the repository returns incorrect type definitions or if you try to connect to a CMIS 1.1 endpoint. (DotCMIS does not support CMIS 1.1, yet). Can you download this document with the CMIS Workbench? - Florian > Hello, > > > > Using DotCMIS 0.7 version and trying to download a document using > > IObjectId _oid = > session.CreateObjectId(co["cmis:objectId"].FirstValue.ToString()); > > IDocument cmdoc = session.GetObject(_oid) as > IDocument; > > IContentStream retdoc = cmdoc.GetContentStream(); > > > > > > I get an error on the GetObject (_oid) on resolving the object to an > IDocument I get an CMISRuntimeException: > > > > Property 'gu:letterCharacteristic' doesn't exist! > > > > at DotCMIS.Client.Impl.ObjectFactory.ConvertProperty(IObjectType > objectType, IPropertyData pd) > > at DotCMIS.Client.Impl.ObjectFactory.ConvertProperties(IObjectType > objectType, IProperties properties) > > at DotCMIS.Client.Impl.AbstractCmisObject.Initialize(ISession > session, IObjectType objectType, IObjectData objectData, > IOperationContext context) > > at DotCMIS.Client.Impl.Document..ctor(ISession session, IObjectType > objectType, IObjectData objectData, IOperationContext context) > > at DotCMIS.Client.Impl.ObjectFactory.ConvertObject(IObjectData > objectData, IOperationContext context) > > at DotCMIS.Client.Impl.Session.GetObject(String objectId, > IOperationContext context) > > at DotCMIS.Client.Impl.Session.GetObject(IObjectId objectId, > IOperationContext context) > > at DotCMIS.Client.Impl.Session.GetObject(IObjectId objectId) > > > > > > The object has extended properties (found this out on using the > CMisWorkbech). > > > > I'm only interested in getting the actual stream and not the > properties so I tried to do the same with > session.GetContentStream(_oid); > > > > but then the stream is empty : > > > > [DotCMIS.Data.Impl.ContentStream]: {DotCMIS.Data.Impl.ContentStream} > > FileName: null > > Length: null > > MimeType: "application/pdf" > > Stream: {System.IO.BufferedStream} > > > > How can i resolve this quickly ? > > Thanks in advance, > > Erwin Moll > >
