How to get rendition copy of word document from alfresco repository using CMIS

I created one custom web application. through that i am uploading some document to alfresco repository. i also created one PDF viewer to view document in UI.

Now the problem is, i am only able to view PDF type of document, but i am uploading different type of document in repository.

So i want a rendition copy of all documents which i uploaded in repository. i already have written CMIS code to fetch document and display in viewer.

now i just want rendition copy of document.

can any one help me with this. if possible, please provide sample source code.

Thanks in advance

This blog post discusses Alfresco's interpretation of CMIS renditions and includes Java code that shows how to retrieve them.

To save you a click, the code from that blog post is:

OperationContext context = session.createOperationContext();
context.setRenditionFilterString("cmis:thumbnail");
CmisObject doc = session.getObjectByPath("/Sites/ren/documentLibrary/Spring Surf and OpenCMIS Integration", context);
List<Rendition> renditions = doc.getRenditions();
for (Rendition rendition : renditions)
{
   System.out.println("kind: " + rendition.getKind());
   System.out.println("mimetype: " + rendition.getMimeType());
   System.out.println("width: " + rendition.getWidth());
   System.out.println("height: " + rendition.getHeight());
   System.out.println("stream id: " + rendition.getStreamId());
}

Which dumps:

kind: cmis:thumbnail
mimetype: image/png
width: 100
height: 100
stream id: workspace://SpacesStore/ef7e9a9b-c847-4023-b527-17243c72ade6

You can use that stream ID to fetch the actual rendition object and its content stream.

I hope I have well understood your question :

Lets admit that your alfresco is well configured and that when you go on share, your document (.doc & Cie) is rendered in the viewer.

If your document has this nodeRef :

workspace://SpacesStore/289e60a1-8b77-48da-ac53-4c2f3e81aa97

Then you can have a pdf rendering with this url :

https://localhost:8080/share/proxy/alfresco/api/node/workspace/SpacesStore/289e60a1-8b77-48da-ac53-4c2f3e81aa97/content/thumbnails/pdf?c=force

This way, you always handle pdf in your application.

Be aware that the rendering can take some time and ressource from the server.
