We store our binary data in MarkLogic but use XQuery only to return a
byte stream of the object. From that point a Java servlet handles
returning the stream to the browser. One advantage of that architecture
is that the servlet context will already know the correct MIME type for
a given file extension, so we don't need to hand-code whether we're
returning image/jpeg or audio/mpeg.
As for your second question, I don't know if it's possible to define a
function inside your JSP but I doubt you would want to. Architecturally
it would be better to store library functions in a centralized place
(either on the filesystem or in the database) where they can be used by
multiple pages.
Hope this is helpful.

Hi,
My first question is regarding display an image from JSP when the
image is stored in Marklogic server.
I have tried 2 things in the JSP as listed below:
*1. (No Result - Red cross mark in place of the image. Server could
not execute the xqy file)*
<image width="400" height="300"
src="get-img-jpeg.xqy?uri={fn:base-uri(doc("c:/100_2754.JPG")))"/>
Here I have tried to call a XQY file with the input of the uri of the
image. The XQY file has the code like the following:
module "http://www.w3.org/2003/05/xpath-functions";
let $uri := xdmp:get-request-field("uri")
return (xdmp:set-response-content-type("image/jpeg"), doc($uri))
It does not show me the image. I want to know
i) How can I call an xqy file from a JSP?
ii) Can I define XQY functions inside a JSP? What will be the
syntax?
*2. (return nothing)*
<xq:execute >
<xq:query>
let $uri := fn:base-uri(doc("100_2754.JPG"))
return (xdmp:set-response-content-type("image/jpeg"), doc($uri))
</xq:query>
</xq:execute>
*/I don't want to store the images in the file system and want to
store them in marklogic. Please tell what shall be the right way to
solve this problem./*
*/ /*
*/Please also let me know if it is possible to define xquery function
in the JSP and call XQY from JSp?/*
*//*
*/Thanks in advance,/*
