Add a document as a version to another document

Hi,

I want to add a doucment (available on CS. Call it A) as a version to another document (say using Webservices. I understand we use the

fDocMan.addVersion(nodeID, new Metadata(), attach)

How do i set my attach parameter to identify a file on CS ? Any sample code would be appreciated. Is DownloadContent (of A and attaching this as a verson to the option ? I am worried if the file size is huge it may cause memory leaks, performance, time out etc.

Thanks,

Madhu

I doubt if the vended services allow you to add an existing version to another node however at the lliapi Oscript level it is available I seem to have used it so it may be possible to devise your own implementation

If you use content service and the contexts it gives you do you think the stream wouldn't complete?

Hi Appu,

Thanks for the reply. We are using DownloadContent and MemmoryStream for this. We have tried until 50 MB. It was fine. However we suspect the code would fail for heavy files. Below's the code we are using.

*************************************************************************

Stream downloadStream;

using (var contentServiceClient = new ContentServiceClient())

{

downloadStream = contentServiceClient.DownloadContent(ref otAuth, docContextA);

}

using (var memoryStream = new MemoryStream())

{

downloadStream.CopyTo(memoryStream);

contents = memoryStream.ToArray();

}

var attach = new Attachment

{

Contents = contents,

FileName = getDocInfo.Name,

FileSize = contents.Length

};

var metadata = new Metadata

{

AttributeGroups = getDocInfo.Metadata.AttributeGroups

};

docManClient.AddVersion(ref otAuth, docB, metadata, attach);

*************************************************************************

Thanks,

Madhu

Hi Kampe,

How are you?

I'm a Java programmer and the Attach object that you need you can get making this:

Attachment attach = new Attachment();
attach.setFileName("The document's name");
attach.setCreatedDate(Date);
attach.setModifiedDate(Date);
attach.setFileSize(docArrayByte.length);
attach.setContents(docArrayByte);

But first you should to convert your file (for example: A datahandler object) to byte[].

You can use the IOUtils apache lib:

IOUtils.toByteArray(YOUR_DOCUMENT.getInputStream());

I hope that help you.

Bless and regards!
