Java from XQuery

Hi All, It is not clear to me if I can run from XQuery a .jar file (it is a simple linguistic parser). Any idea about that? Thanks. Joseph

To me, it's not clear what you mean with "running a jar file"? Would you like to invoke the class that's specified in the MANIFEST.MF file, or any other class? Christian

Hi Cristian, Yes, I mean the main method of the class specified in the main-class header in MANIFEST, which is executed when you command: java -jar file.jar Thanks! J.

I see. In that case, you should add the JAR file to your classpath and address this class in your XQuery code via our Java binding [1]. If the JAR file cannot be added to the classpath, you will need to start a separate Java process and address via the process module: proc:system("java", "-jar", "...") [2].

Hi Cristian, I have used the proc:execute function for a java command and it works. I use that to invoke a linguistic parser whose output is by default written into a file (XML). I would like to open such a file with doc(), but doc() is processed before the file created with proc:execute is written into the file. What is the best way to force doc() to wait until the file outputted by proc:execute is written? Thanks. J. Ps: is there any significant difference in performance between using java bindings and proc:execute?

I reforward this email, if anyone knows about this problem: I have used the proc:execute function for a java command and it works.

Hi Joseph, This works for me. Where parser.bat is creating out.xml in the folder where the xquery is running. This maybe a case of trying to stop the optimizer, some simpler versions of this did not work
let $uri-process:=file:resolve-path("parser.bat",static-base-uri())
let $uri-output:=file:resolve-path("out.xml",static-base-uri())
let $_:=proc:execute($uri-process)
return doc($uri-output)
/Andy
