Hi Mickaël,

You might need to convert the resulting byte sequence to a xs:base64Binary item:

convert:integers-to-base64( Q{java:java.lang.String}get-bytes('xyz') )

If that doesn’t help, feel free to provide us with your full RESTXQ function.

Best, Christian

Hello,

Probably my ignorance, but I struggle to send a byte array (byte[]) from a java module to a restxq response.

Something a bit like this:

    return
    (<rest:response>
        <http:response status="200">
            <http:header name="content-type" value="application/pdf"/>
        </http:response>
    </rest:response>,
    SomeJavaModule:getSomeBytes($module_instance))

I know there is a binary module in BaseX but I tried various things and couldn't get the wanted output. I could probably write the bytes in a file and then use file:read-binary() but it's something I'd like to avoid.

Any clue here ?
