[oXygen-user] Debugging MarkLogic AppServer xquery code

[Lee, David]

Thank you, that would be a very useful feature.
Another useful feature would be to be able to either connect to a
running XQuery from the APP Server,
or to simulate the request arguements.  
For example if I have a xquery running in mark logic app server (not the
XDBC server)

And I call it via a URL from a brower like
	http://marklogic:1234/myquery.xquery?arg=value

Inside that query I can use

	let $arg := xdmp:get-request-field("value")


Your suggestion of xdmp:invoke() I dont think simulates the request
fields passed in from an HTTP invocation of an xquery running in the App
server component of markLogic.

An idea I had is to try to make a very thin wrapper (that hopefully is
easy enough to be bug free :)
that gets the request fields, then turn that into an invoke on a xquery
which expects external parameters instead of request fields.  Then I
might be able to debug that xquery in Oxygen using parameters.

Hello,

You can execute a local XQuery that invokes an XQuery from the MarkLogic

server and the XQuery is executed on the server but debugging does not 
step into the XQuery from the server. For example the following local 
XQuery invokes an XQuery from the server:


xdmp:invoke("/movies.xquery")


We will contact the MarkLogic developers to find if they plan to add 
this feature on the server.


Regards,
Sorin
