Java bindings
by meumapple 06 Mar '17

Hi, I have a java parser (opennlp-tools-1.7.2.jar) whose main class is "opennlp.tools.cmdline.CLI" At the command line I run it with opennlp POSTagger mymodel.bin (opennlp is a bash script running the abovementioned jar file). After that I am asked interactively for the text to parse. Is it possible to invoke the command from XQuery via java bindings? I have put the opennlp jar files in the repo folder and I have tried "import module namespace m = "java.opennlp.tools.cmdline.CLI;" but the I get the "module not found error" Thanks! Joseph

Hi Christoph, it worked for me when putting the rest_errors.xqm in the webapp folder and rewrriting your import in this way: import module namespace err="error" at "rest_errors.xqm"; > curl -v http://localhost:9984/softwareberatung/rev/2017/12 Trying 127.0.0.1... * Connected to localhost (127.0.0.1) port 9984 (#0) > GET /softwareberatung/rev/2017/12 HTTP/1.1 > Host: localhost:9984 > User-Agent: curl/7.47.0 > Accept: */* > < HTTP/1.1 404 Not Found < Set-Cookie: JSESSIONID=6ylp1ounz561183u198394hjs;Path=/ < Expires: Thu, 01 Jan 1970 00:00:00 GMT < Content-Type: text/plain;charset=UTF-8 < Content-Length: 25 < Server: Jetty(8.1.18.v20150929) < * Connection #0 to host localhost left intact Revenue 12 does not exist Working with the repo is something that I never got right but probably I should just carefully re-read the docs at [1].

preserve auth behavior like older basex versions
by Erik Peterson 05 Mar '17

05 Mar '17

For RESTXQ auth its unclear to me what the entry is to preserve older versions of basex auth. Thank! see... http://docs.basex.org/wiki/Web_Application - Authentication was readded to RESTXQ. As a consequence, you need to specify the admin user in your web.xml file if you want to preserve the behavior of older versions of BaseX. - In turn, if users are defined in the web.xml file, no passwords must be specified anymore. - The server-side authentication method, and default users, are now enforced and cannot be overwritten by client.

Hi, i tried to return http-status 404, but my service returns status 400: This is the code in my XQuery: fn:error(xs:QName('error'), 'Invoice ' || $id || ' does not exist', 404) This is what curl prints: * Trying 127.0.0.1... * Connected to localhost (127.0.0.1) port 8984 (#0) > GET /softwareberatung/revenues/2015/15-123 HTTP/1.1 > Host: localhost:8984 > User-Agent: curl/7.47.0 > Accept: */* > < HTTP/1.1 400 Bad Request < Set-Cookie: JSESSIONID=cfedc7x61od51p8o40uxm8dfe;Path=/ < Expires: Thu, 01 Jan 1970 00:00:00 GMT < Content-Type: text/plain;charset=UTF-8 < Content-Length: 97 < Server: Jetty(8.1.18.v20150929) < Stopped at /home/christoph/basex/restxq/Revenue.xqm, 64/19: * Connection #0 to host localhost left intact [error] Invoice 15-123 does not exist Regards Christoph Gaukel

Hi, In a file with a structure like <l> <d> <f>a</f> <f>b</f> <f>c</f> </d> <d> <f>a</f> <f>b</f> <f>c</f> </d> </l> If I type doc($b)//f[1]/following::f the processor gets out of main memory, even though the file is about 2.2MB and the structure is simply the one showed above (many sibling d elements) Any idea why? Thanks Joseph

[DBA] jobs-users/server-sessions
by Fabrice ETANCHAUD 03 Mar '17

03 Mar '17

Dear all @BaseX, Could you please explain the exact meaning of the server sessions table in the dba jobs-users window ? I expected to find a list of (servlet) sessions, but instead one can see all the session variables (and among them the session ids). Is it expected behavior ? In that case what does it mean to 'kill' a session variable ? Thank you for showing session ids in the log ! Best regards, Fabrice Etanchaud Groupe FBO

Re: [basex-talk] basexhttpstop hangs in 8.6.1

Hi Tim, The problem has been fixed with the latest snapshot (thanks to Marco for providing me with more details).

[REST-XQ] cookies and path cookie
by Fabrice ETANCHAUD 02 Mar '17

02 Mar '17

Dear all (again ;)) As BaseX as a Web Application can serve several 'sub' applications, I ran into the following issue : 1- Logged in into the DBA interface 2- Session:close() in another rest-xq end point (in the same browser) 3- I got disconnected from the DBA interface It seems normal behavior because cookie is shared among all basex applications in the same Web Application (path cookie is the same for all sub applications). I cannot figure out how we could easily have private cookies for each 'sub-application' ? Best regards, Fabrice Etanchaud

basexhttpstop hangs in 8.6.1
by Marco Lettere 02 Mar '17

02 Mar '17

Hello all, I just downloaded Basex861.zip for Linux (Ubuntu 16.04 the host). Unizipped and started basexhttp. Everything ok. In another shell I launch basexhttpstop which correctly shuts down the server started before. But basexhttpstop itself does not terminate. This is causing some headache in our scripts that launch and stop several instances. Any clue? Thanks a lot, Marco.

Connection reset by peer: socket write error
by France Baril 01 Mar '17

01 Mar '17

We have about 40 databases in out project, but when trying to save files to one of them, users sometimes get this error. We're saving through webdav, on a network connection. We're on version 8.2.3 and cannot upgrade right now. Any clue would be useful. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com
