How to get the Content from Repository

rameshbelli — Tue, 02 Mar 2010 17:06:44 GMT

Hi all, I tried the getContentStream method in the ObjectService and my request is like this<getContentStream xmlns="http://docs.oasis-open.org/ns/cmis/messaging/200908/"> <repositoryId>84ccfe80-b325-4d79-ab4d-080a4bdd045b</repositoryId> <objectId>workspace://SpacesStore/4d

Still getting the null value when I called the GetContentStreamResponse.getContentStream().getStream() method

Hi Rmaesh,

I am able to fetch document properly.

Following is my Axis2 environment.

Alfresco version   - 3.2r2 (community)
Axis2 version       - axis2-1.5.1-bin
Rampart version - rampart-dist-1.5
Java version        - 1.6

I have generated stub classes using Apache ADB binding, I have not tried XmlBeans binding.
I have configured client.axis2.xml for security configuration. So no need to set security header programatically.

I will try using XmlBeans binding stub and see if I get same error on my side or not.
