[Monetdb-developers] MoneDB/XQuery problem (importing a module, http access)
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"?> env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope"env:Body<env:Fault
env:Codeenv:Valueenv:Sender</env:Value></env:Code>env:Reason<env:

xml:lang="en">xquery_module_load: could not load module.
Due to earlier error: parse error: syntax error, unexpected $end on line 1, column 0 parse error: XQuery parsing failed </env:Text></env:Reason></env:Fault></env:Body></env:Envelope>
Note that I can do this (add documents, delete,list...) without any problem using the mclient XQuery.(I think that it's a problem of HTTP access, but I couldn't fix it)
2. Another problem is that I cannot make use of XQuery module, because whenever I import a module i get an error. Here is an example of a simple xquery module from the tutorial that I was tried to import:
-the XQuery module saved in E:\Program Files\CWI\MonetDB4\share\MonetDB\xrpc\export\xrpc-mod.xq
module namespace foo = "xrpc-test-function";
declare function foo:add($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 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.
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...
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
