I believe your code will not work because of the url you are creating is not right.

Please, take a look at this one, which is the right one, generated by Share when you click the Download action:

http://localhost:8081/share/proxy/alfresco/slingshot/node/content/workspace/SpacesStore/60bcd2b9-73fe-4f7a-addc-27c449d4caca/Especifica%c3%a7%c3%a3o_T%c3%a9cnica_OS207.pdf?a=true

One idea is to try to find in Share's source code the part responsible for generating the url.

Which version of alfresco-opencmis-extension are you using ,TransientCmisObject is not used any more. You need to use the latest 1.0 version of alfresco-opencmis-extension

Or you can try to remove

params.put(SessionParameter.OBJECT_FACTORY_CLASS,
"org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");

from my exmple code.

The easiest way is to download the content into a temp folder under real path your webapp .

and redirect your request to that file.
