DFS file upload from Sharepoint

I have a business requirement to tranfer the files from Sharepoint list to Documentum repository using DFS.

While surfing in the net and after quite a bit of googling, i came across a sample project from emc, which is "emc-dfs-sdk-6.5" .

After downloading this, i found a lot of dot net codes grouped together which forms a sample to tranfers and make certtain file operations across folders, cabinets and also moving them.

However, my business requimentw as to upload the file from Sharepoint list to Documenum. On further investigating the code, i have found a specific function

CreateDemoObjects inside the class SampleContentManager class file.

N.B there is JAVA sample also included in the package followling the same architecture.

So, this is a question to the forum as i am really stuck in the below statement

sampleDataObject.Contents.Add(new FileContent(Path.GetFullPath(contentPath), "msw8"));

As it can be clearly seen that it is using the path of the file which was attached with the solution.

However, for uploading a file from a different repository, how do we go about grabbing the file.

I do not know, if this is the intended forum, DFS forum.

Please direct me to the one, if this is not the intended forum.

Thanks

Not clear about what you want to achive.

DFS supports to upload content with various formats. FileContent is the way to upload a client local file to repository. You can also upload the content with binary or dataHandler. DFS manages to do the content transformation.

what i want to achieve?

I have a sharepoint library which contains documents/files.

I want to upload these files to Documentum repository.

How do i do that?

I am using "emc-dfs-sdk-6.5" to upload the files.

You mentioned "You can also upload the content with binary or dataHandler. DFS manages to do the content transformation." Could you please help me with a sample code.

I have no experience on the sharepoint library so I am not able to give you the direct answer. But you can try to choose following solutions:

1) If the sharepoint library is able to detect the file location in file system, you can upload it with FileContent(path, format), as the sample telled.

2) If the file is small, you can read the file to a byte arrary and upload it with BinaryContent(byte[], format).

3) If the file is large, you can read it using a stream handler and upload it with DataHandlerContent(dataHandler, format).

For large content, MTOM content transfer mode is recommended.

Please refer to DFS dev guide for the content datamodel and scenarios.

The example i have found in "emc-dfs-sdk-6.5" has

FileContent(path, format),

For

DataHandlerContent(dataHandler, format).

BinaryContent(byte[], format)

Do we have any example?

Thanks..so much for the reply

The DFS development guide documentation has some examples around these additional methods.

I have found

private DataHandlerContent getDataHandlerContent (byte[] byteArray, String format)

{

DataSource byteDataSource = new ByteArrayDataSource(byteArray, "gif");

DataHandler dataHandler = new DataHandler(byteDataSource);

DataHandlerContent dataHandlerContent = new DataHandlerContent();

dataHandlerContent.setFormat(format);

dataHandlerContent.setValue(dataHandler);

return dataHandlerContent;

}

private BinaryContent getBinaryContent (byte[] byteArray, String format)

{

BinaryContent binaryContent = new BinaryContent();

binaryContent.setFormat(format);

binaryContent.setValue(byteArray);

return binaryContent;

}

in the DFS guide.

However, i would need the dot net equivalent.

e.g., I dont seem to find the DataHandler class in dot net.

Takea look at the namespace Emc.Documentum.FS.DataModel.Core.Content.

This has all the Content related classes. choose the most appropriate for your needs from there and remember that the documentation states that the .NET DataHandlerContent is for compatibility and should not be used as there are better methods for .NET.

For your case you have a document that if you can get the bytes for, a BinaryContent object would work. If you have the filename then use a FileContent object (but remember that needs UCF so it might be a no go).

For your solution I would say that BinaryContent is the class to use and set the transfer mode to be MTOM and the underlying DFS implementation will delegate to the requisite .NET WCF classes to do the work.

You cvould even create your own Content subclass and use that, but that is probably more work than needed.
