Hello David,
No luck, I am getting following error when I try your suggestion:
com.marklogic.xcc.exceptions.XQueryException: XDMP-TOOFEWARGS: (err:XPST0017)
fn:document-uri() -- Too few args, expected 1 but got 0 [Session: user=user,
cb=XCCTestDB [ContentSource: user=user, cb=XCCTestDB [provider:
address=localhost/127.0.0.1:8006, pool=1/64]]] [Client: XCC/4.2-7, Server:
XDBC/5.0-1]in /eval, on line 1expr: fn:document-uri() at

com.marklogic.xcc.impl.SessionImpl.submitRequest(SessionImpl.java:268)
Basically I want to be able to get images stored in Marklogic server back on a
JSP page in an <img> tag. So far, I can get the html content upto the JSP page,
however to render image, I want to be able to use the same name used while
storing the image in Marklogic database e.g. image1,2,3 etc as document URI.
I tried following in QConsole which works but there are two problems with it:
for $x in collection("user10")returnfn:document-uri($x)
Problem:1 : It retrieves only the file names so I will have to write one query
to get the content and other query to get the file names, that does not sound
quite right.
Problem:2:Even if problem-1 is not an issue, how do I get it to work from Java
code? Should I copy these lines in a .xqy module/page and invoke it somehow
from JSP?
Is there any better way to get image and it's document-uri in one go from
Marklogic. I stored them as binary instances when creating content. I am using
Marklogic-5.

Try this:
Request request = session.newAdhocQuery("
collection('imageCollection')/document-uri() ");

Subject: [MarkLogic Dev General] Retrieving file name/document URI of binary
content
Dear all,
I am learning ways of doing things in Marklogic server. I have managed to save
a collection to Marklogic server which consists of few .gif images.
The document URI's are the actual file names when I stored them in collection
e.g. image1, image2 etc..The collection is named "imageCollection". I can query
for "imageCollection" and it does return 3 images in result set. Unfortunately,
I am unable to figure
out how to get "file name" or Document URI of these images ?
createOptions = ContentCreateOptions.newBinaryInstance();
createOptions.setCollections(new String[]{"imageCollection"});
createOptions.setFormatBinary();
content =
ContentFactory.newContent(someContent.getAttachmentsFileNames()[i],
someContent.getAttachments()[i], createOptions);
System.out.println("Inserting contents..");
session.insertContent(content);
The call to
Request request = session.newAdhocQuery(" collection(\"imageCollection\")
");
ResultSequence rs = session.submitRequest(request);
while(rs.hasNext()){
System.out.println("Inside contentDao 44444444");
ResultItem item = rs.next();
Following call returns null
System.out.println(item.getDocumentURI());
Please help me understand how to get the file names of the images so that I can
use them to render back on screen.
Thanks
