Hi Mike (cc @ basex-talk), you're right, Firefox seems to have problems rendering the page (Opera and Chrome didn't cause any problem in my ad-hoc test)..

External variables in GUI
by Mike Rothon 24 May '11

24 May '11

Firstly I apologise if this has been asked before, but I cannot work out how to search this mailing list without downloading all the archives first. I am working through the XQuery in 10 minutes tutorial and trying this XQuery: declare variable $firstName as xs:string external; <videos featuring="{$firstName}"> { let $doc := doc('http://www.stylusstudio.com/examples/videos.xml') for $v in $doc//video, $a in $doc//actors/actor where ends-with($a, $firstName) and $v/actorRef = $a/@id order by $v/year return <video year="{$v/year}"> {$v/title} </video> } </videos> It's fine in standalone mode (command line), but I cannot find a way of supplying an external variable in the GUI. Thanks and regards.

Re: [basex-talk] base-uri and put statement

Hi Sebastian, thanks again for your report. There's a problem with the implementation of fn:put as the current solution based on Java FileOutputStream can't handle the kind of URI we discussed earlier [1]. We'll let you know as soon as we fixed this issue.

base-uri and put statement
by Sebastian.Wiemer＠Bertelsmann.de 24 May '11

24 May '11

Hello, In an fn:put(TempNode,URI) I would expect base-uri(Node) as a URI parameter to work. But base-uri(Node) returns on Windows "file:/C:/somepath/somefile.xml", which does not work, because the URI cannot be opened. The URI "/somepath/somefile.xml" works. And file://C/somepath/somefile.xml does also work. Is this a bug? example: let $doc:= doc("bla.xml") put( copy $temp := $doc modify replace value of node $temp/n with lower-case($temp/n) return $temp,base-uri($doc) ) (: this does not work, but should it not? :) best regards, Sebastian

Fwd: Incorrect implementation of XQUF?
by software developer 23 May '11

23 May '11

Hi, All I did was upgrade from 6.5.1 to 6.6.3-SNAPSHOT which I took from BaseX file-server today (a couple of hours ago) and I get: Not expected (Data Access out of bounds [pre:2050100, indexSize:8028, access:8028 > 8027] This is quite similar to the issue I faced when I raised the original query regarding XQUF (this thread). Immediately downgraded to 6.5.1 and the issue got fixed (I did not update the data at all). Thanks.

(Poss.) Bug Report BaseX 6.6.2
by Loyde Yates 22 May '11

22 May '11

Dear BaseX, Don't know if this is important. I'm new to BaseX, but I thought I should relay the entry I received when attempting to download info into BaseX. The six previsous files seem to load okay. I still have to learn more to make that determination. Thanks for making the software available! Loyde Yates Error: Possible bug?

JAXRXPATH property, Basic auth
by Computer Software Developer 21 May '11

21 May '11

1. After upgrading to 6.6.2 from 6.5.1, JAXRX cannot find my xquery files stored on server side even though the property JAXRXPATH is defined and is pointing to the directory containing the xquery files, the directory is mounted. Any pointers on how it should be configured? Below is the ~/.basex file's contents: DBPATH = /home/developer/BaseXData JAXRXPATH = /media/queries/ LANG = English LANGKEYS = false HOST = localhost PORT = 1984 SERVERPORT = 1984 JAXRXPORT = 8984 TIMEOUT = 0 Do I need to specify RESTPATH instead (if I do that, I get RESTPATH not found message upon JAXRX server startup)? 2. I have been trying to provide basic auth using admin:admin@localhost:8984 notation in the URL in Firefox, but Firefox says the web-site does not require authentication and then does not apparently pass the auth header to JAX-RX. Does JAX-RX not return 401 with WWW-Authenticate header so the user can authenticate? Thanks.

Determine remote server version.
by Huib Verwey 20 May '11

20 May '11

Hi all, I'm trying to determine the BaseX version running a remote server. When I connect using the client on my local machine the server does not say which version it is When I use the GUI to connect to the remote server I can't find any info on the version. When I login to the remote machine and go to the server folder I can't find any info on which version it is. When I look at the logs in the .logs folder I can't find any info on the server version (I could not find the startup info that the server generates). I copied the BaseX.jar to a place where I could unpack it and found version "6.6" in the META-INF/maven/org.basex/basex/pom.xml file. Is there a more convenient way of determining the remote version that I missed? And did I actually find the correct version in the pom? Hartelijke groet, Huib Verweij. P.S. In the BaseX GUI the "Logs" tab shows me the logs of the local BaseX even when I connect to a remote BaseX - could be on puprpose, I just found it somewhat counter intuitive.
