Re: [Monetdb-developers] MoneDB/XQuery problem (importing a module, http access)

Hello Clarisse, First of all, thanks for your interest in MonetDB/XQuery. It seems that you are facing this problem: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=1899258&group_id=56967 In short, due to a bug in libxml2-2.6.31, it is not possible to load a module (i.e., get the module file) from a URL which uses a different port nr. than the standard port 80. This bug has been fixed by libxml2 in a version >2.6.31. It seems that in your second point, you did not include the complete parse error message. But I guess your second problem is also caused by the same bug in libxml2. I hope this helps a bit. Kind regards, Jennie On Sep 15, 2008, at 12:58 , Clarisse Kagoyire wrote:

Hello, I am a student in GeoInformatics at ITC(International Institute for Geo-Information Science and Earth Observation) and I have just started using MonetDB/XQuery for my MSc Research project. But I am facing some problems and your help will be really appreciated:

1. Whenever I try to use any of the options available in the Administrative GUI(like adding, deleting documents, list collections,...), I get an error message. Here is an example of the error returned if I try to list collections:

!ERROR: "collections execution failed at the remote side"

!ERROR: HTTP/1.1 404 !ERROR: HTTP Response:

<?xml version="1.0" encoding="utf-8"?> http://www.w3.org/2003/05/soap- envelope">env:Bodyenv:Faultenv:Codeenv:Valueenv:Senderenv:Reasonxquery_module_load: could not load module.

Due to earlier error: parse error: syntax error, unexpected $end on line 1, column 0 parse error: XQuery parsing failed

Note that I can do this (add documents, delete,list...) without any problem using the mclient XQuery.(I think that it's a problem of HTTP access, but I couldn't fix it)

2. Another problem is that I cannot make use of XQuery module, because whenever I import a module i get an error. Here is an example of a simple xquery module from the tutorial that I was tried to import:

-the XQuery module saved in E:\Program Files\CWI\MonetDB4\share \MonetDB\xrpc\export\xrpc-mod.xq

module namespace foo = "xrpc-test-function";

declare function foo:add($v1 as xs:integer, $v2 as xs:integer) as xs:integer

{

$v1 + $v2

};

-on mclient, I typed the following to import the module:

...

import module namespace test = "xrpc-test-function" at "http://127.0.0.1:50001/export/xrpc-mod.xq ";

...

test:add(100, 200)

Which returned also an error: !parse eroor: error parsing module....

I'm looking forward to hearing from you.

Thank you , Clarisse K.
