[MarkLogic Dev General] Image stored in marklogic server - display it from JSP

[Jason Hunter]

> *1. (No Result - Red cross mark in place of the image. Server could not

> <image width="400" height="300"

> Here I have tried to call a XQY file with the input of the uri of the

>  
> 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))

You wrote a library module (see your module declaration) but are calling 
it like a main module.  If you go to get-img-jpeg.xqy directly (always a 
good step when debugging dynamic images) you'll probably see an error to 
that effect.  Remove the module line to make your code a main module. 
Then you'll probably have success.  If not, try going to the image 
directly and see what other error you might be seeing.

> 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?

JSPs are not designed to return binary streams.  They're for character 
output.
