Deleting content of a file

Dear all,

is there an easy way of deleting the content of a file, without removing
the file itself (clearing it)?

I saw that i can call setContentStream with a new contentstream and that
there is a deleteContentStream but then the file is "broken"

The node's content is missing:
   node: workspace://SpacesStore/28c5a8f1-9589-455c-9afe-262438c61c61
   reader: null

any suggestions?

Okay, I was just wondering, so for Alfresco I came up with this solution
(in case someone else might need it)

        String str ="";
        InputStream bais = new ByteArrayInputStream(str.getBytes());
        ContentStream cs = new ContentStreamImpl(filename,
BigInteger.valueOf(Long.parseLong("0")), "UTF-8", bais);
        doc.deleteContentStream(true);
        doc.setContentStream(cs, true);

 Hi Sebastian,

 From a CMIS point of view deleteContentStream() is what you are looking 
 for.
 Not all repositories support it, though. Some repositories need a 
 content stream with 0 bytes. You should ask the repository vendor.
