I have some doubts about retrieving a pdf file from Jackrabbit.

Currently I stored a PDF file in Jackrabbit like this:


File newFile =3D new File("d:\\BIRTRefCard.pdf");

Repository repository =3D null;

Session session =3D null;

try {

repository =3D new TransientRepository();

//jackrabbit's default JAAS LoginModule (SimpleLoginModule) is just a dummy

//implementation which only distinguishes between anonymous/non-anonymous

//login's. any non-anonymous login has full read/write permissions.

session =3D repository.login(new SimpleCredentials("johndoe","password".toC=
harArray()));

Node root =3D session.getRootNode();

Node fileNode =3D root.addNode(newFile.getName(), "nt:file");

//create the mandatory child node - jcr:content

Node resNode =3D fileNode.addNode("jcr:content", "nt:resource");

InputStream in =3D new FileInputStream(newFile);

resNode.setProperty("jcr:mimeType", "application/pdf");

resNode.setProperty("jcr:data", in);

Calendar lastModified =3D Calendar.getInstance();

lastModified.setTimeInMillis(newFile.lastModified());

resNode.setProperty("jcr:lastModified", lastModified);


session.save();

} catch (LoginException e) {

e.printStackTrace();

} catch (RepositoryException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

} finally {

session.logout();

}


But how can I get the pdf file back from the system?


I tried something like the code below but I am not sure if it is the correc=
t way. I want to stream this pdf to the client


Node root =3D session.getRootNode();

Node content =3D root.getNode("BIRTRefCard.pdf/jcr:content");

final InputStream in =3D content.getProperty("jcr:data").getStream();

final String mime =3D content.getProperty("jcr:mimeType").getString();

.....


Pls help.


Thanks in advance
