Subject problems with getting binary data out of a repository
Date Tue, 01 Apr 2008 21:26:13 GMT
  I am hoping someone can help me with getting binary data out of a 
jackrabbit repository.  I seem to be having some issues with that in an 
application I am trying to work with.

I can get data into the system with:

                Node root = session.getRootNode();
            Node fileNode = root.addNode(file.getOriginalFilename(), 
            Node resNode = fileNode.addNode("jcr:content", "nt:resource");
            resNode.setProperty("jcr:mimeType", file.getContentType());
            resNode.setProperty("jcr:encoding", "");
            resNode.setProperty("jcr:data", new 
            Calendar lastModified = Calendar.getInstance();
            resNode.setProperty("jcr:lastModified", lastModified);

This seems to work fine for getting files into the system and I can 
reliably get them out with:

            Node mroot = session.getRootNode();
            Node root = mroot.getNode("${nodeName}/jcr:content");
            response.contentType = 
            response.outputStream << 

for any text based files.    However, whenever I try to do this with an 
image or PDF the file end up corrupted.  I assume the last .getString() 
is doing bad things (converting my binary to string). 

- Am I missing a flag I need to set when sending a file up to the system 
that tells it is binary?
- Is jackrabbit doing a base64 serialization/deserialization behinds the 
- Is there same way to get the raw binary from the jcr:data node?

If it makes any difference this is running in a spring environment and I 
am letting spring set things up. 

For text, it's all working fine..  just need it to do the same for binary.
