I'm not sure, but I think that it is not possible to get the document url, you should implement your own servlet that returns in the response the byte stream for the download. Probably this problem exists because each product vendor has different servlets to get a content stream.

If you are using the OpenCMIS library, there is no public method dedicated to retrieve the content stream url, but you can use the suggested following method to implement a getDocumentURL using Java Reflections:


public static final String getDocumentURL(final Document document, final Session session) {
    String link = null;
    try {
        Method loadLink = AbstractAtomPubService.class.getDeclaredMethod("loadLink", 
            new Class[] { String.class, String.class, String.class, String.class });
        
        loadLink.setAccessible(true);
        
        link = (String) loadLink.invoke(session.getBinding().getObjectService(), session.getRepositoryInfo().getId(),
            document.getId(), AtomPubParser.LINK_REL_CONTENT, null);
    } catch (Exception e) {
       e.printStackTrace();
    }
    return link;
  }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hope this helps.

hi…
I 've used the above code and it is returning the url…its a great work…but the problem is if we use this url it is asking alfresco login details…
our requirement is to directly download the file with out asking the alfresco credentials…

can any one suggest alternatives…

thanks in advance…

I think you'd better not display document url returned by cmis atom binding to end user.
Instead generate a url for every document,when user clicks your url which send request to your proxy servelt,Then your proxy servlet get the document id and user credentials and use user credentials to download file from repository and send stream to user browser.
