Marcel, thanks!
I can now get baxck my MS-Word file!
an optional encoding when supported by the mime type
How can I find out which mime type supports and/or requires which
encoding? Does the JCR-API support me here?
Thanks for help,
Dirk
BTW: Is there a comprehensive demo application I can have a look at
to further endeepen my JCR knowledge ?
docResourceNode.setProperty("jcr:mimeType", docMimeType);
//resourceNode.setProperty("jcr:encoding", ""); //Needed?

Hi All,
I'd like to ask for help telling me how I can extract the content
of file testwordfile.doc and save it in the local file system. I
am already able to save it successfully into my jackrabbit
repository using the addDocFile() method below. Also, I can find
it using the saveDocMethod() also shown below. But how to extract
the content, to determine e.g. the mime type and to set the
encoding needed to save it successfully?
an nt:resource is just a binary stream and may have an optional
encoding when supported by the mime type. e.g. a word document will
not have an encoding, but a plain text file will have one.
to read the document from the repository you simply navigate to the
binary data property and get the value as an input stream:
Node resource = ...
InputStream in = resource.getProperty("jcr:data").getStream();
// now spool the stream to a local file...

Any help appreciated!
