XQuery process:execute how to execute external programm? - xquery

Question

I am running exist-db on windows and would like to execute an external windows program.
This works inside the normal windows shell:
C:\path\to\webGLRtiMaker.exe C:\path\to\ImageFile.rti -q 90
And I would like to execute the same program from my xquery script (I have uploaded all the needed files according to my specified paths to my exist-db):
xquery version '3.1';
import module namespace process="http://exist-db.org/xquery/process" at "java:org.exist.xquery.modules.process.ProcessModule";
declare variable $options := '<options>
<workingDir>/db/apps/test-project/images</workingDir>
<stdin><line>/db/apps/execute-test/images/image1.rti -q 90</line></stdin>
</options>';
(:process:execute($webRtiMaker, <options/>):)
process:execute('/db/apps/execute-test/resources/RTIMaker/webGLRtiMaker.exe', $options)
Even if I only execute the program without parameters (if I execute it inside windows I get the parameters as overview inside the command prompt so I should also receive some kind of output):
process:execute('/db/apps/execute-test/resources/RTIMaker/webGLRtiMaker.exe', <options/>)
But I get the error:
exerr:ERROR An IO error occurred while executing the process /db/apps/execute-test/resources/RTIMaker/webGLRtiMaker.exe: Cannot run program "/db/apps/execute-test/resources/RTIMaker/webGLRtiMaker.exe": CreateProcess error=2, The System cannot find the file ...
I used this as reference: Execute External Process
What am I doing wrong?

Answer 1

I have not tried this recently, but try the following:
import module namespace process="http://exist-db.org/xquery/process" at "java:org.exist.xquery.modules.process.ProcessModule";
let $cmd := 'C:\path\to\webGLRtiMaker.exe C:\path\to\ImageFile.rti -q 90'
return
<results>{process:execute($cmd, <options/>)}</results>
There is an article at the XQuery WikiBook about it.

Unfortunately it is not possible to start an executable that is stored inside the database. The java API requires direct access to a file on the filesystem, and the '/db/....' path is not.
