yeah man I tried writing the retrieved stream to a file, it is empty. The
file that I save definitely has content (confirmed by less).
Perhaps you can take a look see (the code isn't complicated); having more
experience than me you could identify obvious problems pretty quickly.
here is the save code
public void saveFile(File file, Session session) throws Exception {
// create the file node - see section 6.7.22.6 of the spec
Node folderNode = session.getRootNode();
Node fileNode = folderNode.addNode(file.getName(), "nt:file");
// create the mandatory child node - jcr:content
Node resNode = fileNode.addNode("jcr:content", "nt:resource");
resNode.setProperty("jcr:mimeType", "");
resNode.setProperty("jcr:encoding", "");
FileInputStream fileInputStream = new FileInputStream(file);
resNode.setProperty("jcr:data", fileInputStream);
Calendar lastModified = Calendar.getInstance();
lastModified.setTimeInMillis(file.lastModified());
resNode.setProperty("jcr:lastModified", lastModified);
session.save();
}
and here is the test code
protected void setUp() throws Exception {
super.setUp();
String testFileName = "/tmp/" + getName() + ".txt";
FileWriter fw = new FileWriter(testFileName);
fw.write("some content");
fw.flush();
testFile = new File(testFileName);
}
public void testSaveFile() throws Exception {
Session session = getSession();
dao.saveFile(testFile, session);
Node root = session.getRootNode();
Node fileNode = root.getNode(testFile.getName());
Node fileDetails = fileNode.getNode("jcr:content");
Property fileProp = fileDetails.getProperty("jcr:data");
InputStream retrievedStream = fileProp.getStream();
FileOutputStream fos = new
FileOutputStream("/tmp/retrievedFile.txt");
byte[] buf = new byte[256];
int read = 0;
while ((read = retrievedStream.read(buf)) > 0) {
fos.write(buf, 0, read);
fos.flush();
}
}
