saving files

Rate this Message:
hey all,
more newb questions here. Want to save a file in the repository. found this on the wiki 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", ""); resNode.setProperty("jcr:data", new FileInputStream(file)); Calendar lastModified = Calendar.getInstance(); lastModified.setTimeInMillis(file.lastModified()); resNode.setProperty("jcr:lastModified", lastModified); Is the file itself being put in the repository (jcr.data) or just the content? Do I even need the resNode? Can I just save the file into the fileNode? Finally, we are going to need to lock the file (which is why we are using jcr). Is it possible to attach info (like who owns the lock) to the locked file? Thanx. This community has been quite helpful. -- --------------------- Michael Harris |

All you can really do is retrieve the InputStream for said file. Which
should be enough, and the nodes hold the rest of the info if you need it obviously (file name, type, etc). Something like: Node resNode = fileNode.getNode("jcr:content"); resNode.getProperty("jcr:data").getStream(); Where fileNode is the jcr:file node type. You wont be able to actually get a File object becuase thats part of JCR, that it extracts that stuff away from you, and you just deal with the contents and info. -Nick On Wed, Jul 23, 2008 at 10:16 AM, Michael Harris <michael.e.harris@...> wrote: > ladies and gentlemen > > its still not obvious to me how to retrieve the saved file.

thanx for the reply. when I do that and inspect the returned stream in the eclipse debugger there is nothing in it. michael.

I know that works as I've used it extensively. I am on a 1.5 build, but it
was working with the 1.4.x build I started with. Have you looked at the stream going in to make sure something is actually being saved? You obviously have the node and property there or otherwise you would be getting a RepositoryException. I would check to make sure you are saving everything you think you are. Also, try just using the stream and ignore the debugger (it might be lying to you, who knows). But it looks like everything is in order.

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(); } } On Wed, Jul 23, 2008 at 10:38 AM, Nick Stuart <nstuart@...> wrote: > I know that works as I've used it extensively.

Well the only thats really different between that and my code is setting
mimeType and encoding to empty. I don't touch the encoding at all, and always set the mimeType to something even if it is just text/plain. Other then that it looks about the same. Try hardcoding at least mimeType to 'text/plain' and remove the encoding bit and see if you get better results. That may be screwing up the retrieval bit, not sure why it would though. -Nick On Wed, Jul 23, 2008 at 10:56 AM, Michael Harris <michael.e.harris@...> wrote: > yeah man I tried writing the retrieved stream to a file, it is empty.
