Question about Content webservice - DownloadContent operation

Hi Scott and others,

I am trying to download a document. The download content SOAP message requires only <urn1:contextID>?</urn1:contextID>. But I am not sure what it is. I assumed that it is different than the node_id of the document because when I used node_id, I got this fault.

<faultcode xmlns:ns0="urn:Core.service.livelink.opentext.com">ns0:Core.CouldNotLoadMethodContext</faultcode>
<faultstring>CacheUtil: Could not load requested cache object: 502736 (V{<'SEGMENTBLOB'>})</faultstring>

Can you please explain what the contextID is?

I am using SoapUI to get the authentication token and to call the content webservice using this token.

Thanks,

Kapil Chaudhari

Hi, Kapil.

The various *Context() methods (e.g. GetVersionContentsContext()) return a context ID that can be passed to the ContentService. Please see Large Documents (MTOM client) in the Client Guide for more information.

Thanks,

Hi Scott,

Thanks for replying. Is there any webservice I can use to get this contextID instead of building a client for it? One of our customers wants to download the documents using webservice call. I thought we can achieve it using the following 3 step process:

1. Call authenticateUser to get the token (Authentication webservice)

2. Using the token, get the contextID for that document (Not sure which webservice returns it)

3. Using the security token and contextID from step2, he can call content webservice to download the document. (Content Webservice)

Thanks,

Hi, Kapil.

I'm not sure what you mean by not building a client... something will have to issue the requests to the web services and handle the responses.

Your three-step process sounds right. For Step 2, you should be able to use DocumentManagement.GetVersionContentsContext() to retreive a context ID that you can pass to ContentService.DownloadContent().

Thanks,

Scott

Hi Scott,

Thanks for the quick answers. I am sorry if I confused you by saying "no client". I am not sure what type of client our customer has. But I have been testing all the webservices using SOAPUI.

I used the GetVersionContentsContext webservice to get the contextID and invoked the downloadContent webserive using it. I was able to get the file in the response. I used SOAPUI to test this.

Now, I will have to check with our customer to see if their webservice client supports file transfers.

Thanks,

Hi Scott,

I have one more question related to Authentication webservice call. When i call the authentication webservice with userid and password, I would like to send an encrypted version of the password for security puposes. How can I achieve this?

Thanks,

Hi, Kapil.

Unfortunately, no. The transport itself must be secured using SSL to obscure the password.

Thanks,
