Problem retrieving document from Documentum repository using .net objectService.Get

Hi,

I'm trying to retrieving a document from a Documentum repository from an externa web app using .net.

I'm using the code snippet below (I've tried it for Base64, MTOM and UCF), but each time when I get to the line

'Dim dataPackage As DataPackage = objectService.[Get](objectIdSet, operationOptions)'

I receive a message similar to this 'Operation output generation failed: could not retrieve data for identity: 0906249e80000e95.'

I am able to retreive related metadata content for the object.

Just wondering if there might be something I'm doing incorrectly?

Many Thanks,

allrose

Public Function getDocument(ByVal docIdentifier As String) As System.IO.FileInfo

            'Setup context and service
            Dim t As New EDRMDAO(_User)
            t.setService()

            Dim ctp As New ContentTransferProfile()
            ctp.TransferMode = ContentTransferMode.MTOM
            serviceContext.SetProfile(ctp)

            Dim contentProfile As New ContentProfile()
            contentProfile.FormatFilter = FormatFilter.ANY
            Dim operationOptions As New OperationOptions()
            operationOptions.ContentProfile = contentProfile
            operationOptions.SetProfile(contentProfile)

Try

                Dim objIdentity As New ObjectIdentity
                objIdentity.Value = "0906249e80000e95" 'docIdentifier
                objIdentity.ValueType = ObjectIdentityType.OBJECT_ID
                objIdentity.valueTypeSpecified = True
                objIdentity.RepositoryName = repository

                Dim objectIdSet As New ObjectIdentitySet()
                Dim objIdList As List(Of ObjectIdentity) = objectIdSet.Identities
                objIdList.Add(objIdentity)

Dim dataPackage As DataPackage = objectService.[Get](objectIdSet, operationOptions)

Dim dataObj As DataObject = dataPackage.DataObjects.Item(0)

Dim resultContent As Content = dataObj.Contents.Item(0)

                If resultContent.CanGetAsFile Then
                    Return resultContent.GetAsFile
                Else
                    Return Nothing
                End If

            Catch e As Exception
                Console.WriteLine(e.Message)
                Console.WriteLine(e.StackTrace)
                Console.WriteLine("Failed with exception " & e.Message)
                Return Nothing
            End Try
End Function

Can you get that document using C# client? I'm not sure whether there is any difference.

Also, can you post here the full stack trace of the exception? you may find it from App server log.

I've not tried this particular example using C#, as the environment we're working in is VB.

However when I run the samples provided in the DotNetSampleRunner solution which are in C# e.g. demoRunner.TestMTOM(), demoRunner.TestUCF() and demoRunner.TestBase64(), I get a similar error.

I've attached the stack trace for my example StackTrace.txt and also for the samples StackTrace_SampleCode.txt.

Please let me know if you require any further information.

Hi,

Can you test with FormatFilter.NONE and observe the result? In other words, try to get object without content to narrow the failed cause.

The log you provided are from client side and it did not tell anything helpful. Could you get the server side log, i.e. from JBoss/WebLogic?

When I change the formatFilter = None I still get the same error message.

I've attached the jboss ServerApps.log file. Is this the file your looking for? I'm not familiar with jboss and logging.

Thanks Again,

Liz,

The error message shows a global registry is not configured. You need to update dfc.properties in your emc-dfs.ear/APP-INF/classes and redeploy it.

Typically, the global registry is docbase[0] in your dfc.properties. To enable a repository as a global registry, please refer to Documentum Content Server Administration Guide.

Hi Allrose,

Are you able to resolved this issue?

I am facing similar problem while using Object Services for content transfer using r_object_id.

I am using DFS 6.5 Sp3 with .net 3.5

As per development guide it said we can pass Content Profile and Content Transfer Profile in Operation Options OR Service context.

I trying to do with operationOptions.

Getting Authorization Failed error only.

I have tested my WSDL for ObjectServices for object properties and it work well.

Hi,

Authorization failure has no relation to ContentTransfer or OperationOptions. You need to check if you have set correct ServiceContext header in your request, as well as configured correct dfc.properties in your server application.

If you still don't get your problem resolved, you can dump your request SOAP message and server error log here.

the log file is %JBOSS_HOME%\server\DctmServer_MethodServer\log\server.log if you're using the default JBOSS shipped with Content Server.

pls attach it here.

Hi Folks,

I am able to download a content using DFS 6.5 sp3 with .net 3.5, (with some conditions)

In DFS there are two ways you can communicate with docbase. 1) With Productivity Layer and 2) With NON Productivity Layer

I have tested my code with both. The authorization failed error I was getting because, incorrect information I was passing through SOAP header message, I resolved that.

But come up with wiered error message while doing content transfer.

I tested my code to transfer content for xml and pdf formats, ranging from 1kb upto 1MB (as of now).

I found that,

with Productivity layer

setting Content transfer mode to either BASE64 or MTOM,

1) I can download up to few kb xml file only (1kb to 5kb) (this transfer done with binaryContent transfer),

2) I can download up to 1MB pdf file (this transfer done with URL transfer)

with NON productivity layer

setting Content transfer mode to either BASE64 or MTOM,

1) I can download from few kb up to 1MB xml file, (need to do some settings for buffers). But works fine.

2) I can download from few kb up to 1MB pdf file (this transfer done with URL transfer) same as above.

Dose anyone know what setting need to do with Productivity layer so I can transfer .XML content (or binaryContent) files more than KB (or say in MBs)?

OR is it .net productivity layer dose not support this?

If anyone done this with other than .net, can also suggest the solution, so I can try with .net

Thanks

Pritam
