Hi Helen, You can use xdmp:modules-root() to give you the root of the App Server. Then you can use fn:concat to make the string that combines the root and the module relative path. Then you have to use that when constructing the string for your eval.

I almost made it work. The only thing I have here is: when I do the eval, I need to call a function in a module. The module file is really the same file that I'm building the xdmp:eval query, but I couldn't make eval know the current path this module is, so I have to specify the full path. For example, I have module file at the path /dev/newsci/helen.xqy , and then you can see I put full path import module namespace oit=""http://www.aip.org/helen.xqy";; at "/dev/newsci/helen.xqy"; in my xdmp:eval, this is going to be a problem because the app server's path on our production server will be different. Does anyone know how I can make the path dynamic? or how to avoid this problem? my code piece is like the following: xquery version "1.0-ml"; module namespace oit = "http://www.aip.org/helen.xqy";; declare function oit:mytest() { let $c1 := "http://py"; let $c2 := "http://mytest"; let $cvi := <cvi> <coden>ABC</coden> <volume>90</volume> <issue>1</issue> </cvi> let $oi-state := "PROD" return ( xdmp:eval('xdmp:document-insert("/aa.xml", <foo/>)') , xdmp:eval('xquery version "1.0-ml"; declare variable $e1 as xs:string external; declare variable $e2 as xs:string external; xdmp:document-set-collections( "/aa.xml", ($e1)) , xdmp:document-get-collections("/aa.xml") , xdmp:document-add-collections( "/aa.xml", ($e2))' , (xs:QName("e1"), $c1, xs:QName("e2"), $c2) ) , xdmp:eval( 'xquery version "1.0-ml"; import module namespace oit=""http://www.aip.org/helen.xqy";; at "/dev/newsci/helen.xqy"; declare variable $cvi as element(cvi) external; declare variable $state as xs:string external; oit:create-online-issue-table($cvi/coden/text(), $cvi/volume/text(), $cvi/issue/text(), $state)' , (xs:QName("cvi"), $cvi, xs:QName("state"), $oi-state) ) ) }; then I call oit:mytest() On Jul 7, 2010, at 2:42 AM, Geert Josten wrote: Hi Helen, It is a subtle typo. It sometimes helps to take the query from inside the eval, and test it all by itself in CQ. If you do so, you see the same 'unexpected token' message as you would get when it is inside the eval, but you get a better focus on which line it concerns. In this case it concerns your external variable declarations. There should be no 'as' before the external keyword.. Kind regards, Geert drs. G.P.H.

I did a test like the following: I add a collection to a document, then try to get it, within the same transaction I cannot see the new collection. That means I have to be in the seperate transaction. declare function local:mytest() { ( xdmp:document-set-collections( "/aa.xml", ("http://py";)) , xdmp:document-get-collections("/aa.xml") , xdmp:document-add-collections( "/aa.xml", ("http://mytest";)) , xdmp:document-get-collections("/aa.xml") ) }; local:mytest() How can I make the last line xdmp:document-get-collections("/aa.xml") as seperate transaction so I can see the change?
