Basex: basexhttp Failing to Start with "Server is running or permission was denied"
by Sovello Hildebrand Mgani 22 May '16

22 May '16

Hi! I have downloaded BaseX 8.4.4 and running it on Ubuntu 14.04[.4] I have added basex/bin to $PATH so I can be able to run basex, basexhttp ecc. I can successfully run basex and basexserver. RUnning the HTTP server fails with this message *$ basexhttp* [main] INFO org.eclipse.jetty.server.Server - jetty-8.1.18.v20150929 [main] INFO org.eclipse.jetty.webapp.StandardDescriptorProcessor - NO JSP Support for /, did not find org.apache.jasper.servlet.JspServlet [main] INFO / - Aliases are enabled! Security constraints may be bypassed!!! Server was started (port: 1984). [main] INFO org.eclipse.jetty.server.AbstractConnector - Started SelectChannelConnector@0.0.0.0:8984 HTTP Server was started (port: 8984). Server is running or permission was denied. Server was stopped (port: 1984). and the output when I run *$ basexhttp -d* DEBUG: true BaseX 8.4.4 [HTTP Server] [main] INFO org.eclipse.jetty.server.Server - jetty-8.1.18.v20150929 [main] INFO org.eclipse.jetty.webapp.StandardDescriptorProcessor - NO JSP Support for /, did not find org.apache.jasper.servlet.JspServlet [main] INFO / - Aliases are enabled!

[main] INFO org.eclipse.jetty.server.AbstractConnector - Started SelectChannelConnector@0.0.0.0:8984 HTTP Server was started (port: 8984). java.net.BindException: *Address already in use* at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:387) at java.net.ServerSocket.bind(ServerSocket.java:375) at java.net.ServerSocket.bind(ServerSocket.java:329) at org.basex.BaseXHTTP$StopServer.<init>(BaseXHTTP.java:430) at org.basex.BaseXHTTP.<init>(BaseXHTTP.java:147) at org.basex.BaseXHTTP.main(BaseXHTTP.java:52) Server is running or permission was denied. Server was stopped (port: 1984). Which shows address is already in use. I only have apache2 and have run apache2 and tomcat earlier on the same laptop without issues, and I don't have any service that is listening on that port 8984. (I have tried running BaseX from version 8.0 and get the same errors). Am not sure what is not OK. Can you give me pointers to resolve this?

by Günter Dunz-Wolff 20 May '16

20 May '16

Hi all, for the command file:write($path, distinct-values($list)) I have to check, if $path is existing (for example let $path := ´users/xxx/xxx/etc’. How is it done in XQuery? Thanks for any help. Cheers, Günter

Xquery recursion and db:add() - stack overflow
by Lars Johnsen 18 May '16

18 May '16

The following code generates the error "Stack Overflow: try tail recursion?" The code reads in bibliographic data using OAI-PMH and updates a database for each chunk of data. With OAI-PMH, only part of the data is available for each request, so the server returns a resumption token if there are more data available. The xquery function making the queries is implemented recursively preceded by a database update request (see the last two lines) for each call. Is it db:add() that causes the stack overflow? The recursion cannot be placed further towards the end! declare %updating function local:getResumption($token) { if (empty($token)) then () else let $http-request := http:send-request($http-option, $URL || $token) let $result := if ($http-request instance of node()) then $http-request else <http-err>{$http-request}</http-err> let $resume := $result//oai:resumptionToken/text() return ( db:add($database,element chunk {$result//oai:metadata}, $path) , local:getResumption($resume) ) }; Best, Lars

Faceted search
by Murray, Gregory 18 May '16

18 May '16

Hello, Does BaseX have built-in support for faceted search? I see that there's an easy way to get the facets for the entire database using index:facets(), but is there way to get search results that includes a similar list of facets, based only on those results? Thanks, Greg

question
by Rob Stapper 17 May '16

17 May '16

Hi Chistian, In order to get some path to the element that is being processed I hoped that the following statement [ 1] would return a sequence of positions of each node amongst its siblings. Unfortunately it only returns a bunch of: 1. [ 1] $element/ancestor-or-self::* ! ./fn:position() Should this work? Is there some other ;-) clever way to retrieve a path to a random element that is being processed? TIA for your reply, Rob Stapper

How to restrict access to restxq functions just for the same domain
by Ioan Fericel 13 May '16

13 May '16

Hi, I seemed that this is the behavior if disabling REST Service in web.xml (BaseX.war deploymented on Tomcat), but this does not happen. The surprise is that the functions are accessible from anywhere, if access is not protected by other methods. I'm doing wrong, what should be setting? I use BaseX 8.3. Thanks for any guidance! Ioan

Basex on maven central
by Lance Java 13 May '16

13 May '16

It seems that maven central is not up to date with the latest basex version. I see here that there's only version 7.3.1 whereas on the basex website the latest version is 8.4.4 http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.basex%22 Are there any plans to keep maven central up to date with basex releases?

Recursion error
by Alex R. Loayza 11 May '16

11 May '16

When performing a query on BaseX on a Windows 8 PC, the query runs normally. When doing the same query on a copy of the database in another Windows 8 PC, I get "[bxerr:BASX0005] Stack Overflow: Try tail recursion?" Any ideas as to what could be causing this difference in behavior? Thank you. Alex

dba lags on update
by Marco Lettere 10 May '16

10 May '16

Hi all, I have a single resource in a db. I perform several replace operations on that resource. The dba interface show an increasing number of resources available in the db according to the number of replace operations performed. To get the count of resources back to 1 I need to optimize the database. Anyway, when opening the database the visible content is correct (only the one resource). Seems like the dba interface counts the gone instances of the resource as well ... Regards, Marco.

Re: [basex-talk] Executing xq file from client fails

Problem solved. A database file was corrupted. Re-creating the database solved the problem.
