Make use of external Identity Management for BaseX
by Rob 30 Apr '21

30 Apr '21

Hi, I have a question. Can BaseX make use of an Identity Management application like Keycloak for Users? I can’t find anything about it :) With kind regards, Rob Tjalma

Reloading jars on a running http server.
by Reece Dunn 30 Apr '21

30 Apr '21

Hi all, I'm working on a Java class that I'm importing into an XQuery, so I can do additional processing on the data that isn't easily expressible in XQuery (or XSLT). In order to get BaseX to pick up a modified version of the jar file I'm building, I'm restarting the BaseX http server. This makes it slower to turn around testing the changes. Is there a better way of doing this? Kind regards, Reece

7.9 to 9.4 upgrade
by Bondeson, Carl 28 Apr '21

28 Apr '21

We have been using BaseX for about 10 years. We were stuck at 7.9 because the performance of 8 was too restrictive. We tried 9.4 as a last ditch effort to correct some issues and the performance was just as good as 7.9. You made mention that many tcp/ip issues were resolved. We are using BaseX in a multithreaded client server configuration. I have architected a singleton as the server, allowing synchronized clients access to it. Everything is fine until we are under heavy load. We get the following error. IO exception Software caused connection abort: socket write error in mapperProcess query: declare option output:item-separator ""; distinct-values(for $h in //Concept[@NameSpace='Pilotfish.MergeLevel'] for $d in //Concept[@NameSpace=$h/AssociatedConcept/@NameSpace and .=$h/AssociatedConcept/@Concept] where $h/@Value='ByProductCodeDaily' return $d/@Value) retries: 9 We try 8 times, with a 100 msec wait between each attempt, and then generate an exception on the 9th. We have added tcp/ip registry fixes (MaxUserPort, TcpTimedWaitDelay) to the Windows server as a recommended fix for these types of errors. Do you have any other suggestions? Thanks for a great product!

BaseX and Oxygen scenario
by Zimmel, Daniel 22 Apr '21

22 Apr '21

Hi, am I right in assuming that in order to use the XQJ interface as described here (https://docs.basex.org/wiki/Integrating_oXygen) , you will always need a running local database instance of BaseX? I am not able to use the BaseX.jar standalone in a transformation scenario as I would for example do in a custom ant scenario where I can use BaseX as a standalone transformer (using it as a commandline process). Thanks, Daniel

Using other Java runtimes?
by Peter Villadsen 21 Apr '21

21 Apr '21

Guys, I was wondering what the options are for running BaseX on top of a runtime that is different from the Oracle one? I see Oracle is aggressively monetizing the Java runtime, but I know there are alternatives out there. Have any been tested with BaseX? Best Regards Peter Villadsen Principal Architect Microsoft Business Applications Group

Re: [basex-talk] Using other Java runtimes?

Hello Peter, I’ve been running a system using Amazon’s Corretto 11 from their Docker image with good results. I did also play with using AWS Lambda to run BaseX but I’ve never put anything into production - I had success there with both the openjdk 1.8 and Corretto options.

Java type mismatch when reflecting.
by Andreas Mixich 15 Apr '21

15 Apr '21

Hi I can successfully create an object instance of https://www.stringtemplate.org/api/index.html when using the parameter-less default init: declare namespace ST = 'java:org.stringtemplate.v4.ST'; let $template := "Hello <who>" let $stInstance := ST:new($template) let $call := ST:add($stInstance, "who", "World!") return ST:render($stInstance) Template delimiters can be changed by supplying left and right delimiters (type char) upon init (by default ST4 uses < and > as template delimiters). The signature for this would be: ST(java.lang.String template, char delimiterStartChar, char delimiterStopChar) Documentation is at https://www.stringtemplate.org/api/org/stringtemplate/v4/ST.html#ST-java.la… So I defined the types at invocation, but executing following code I get an error. declare namespace ST = 'java:org.stringtemplate.v4.ST'; let $template := "Hello $who$" let $stInstance := ST:new·java.lang.String·char·char($template,"$","$") let $call := ST:add($stInstance, "who", "World!") return ST:render($stInstance) The error is: [XPTY0004] java.lang.IllegalArgumentException: argument type mismatch. Caused by: org.stringtemplate.v4.ST(String, String, String). The query plan of this unsuccessfull invocation is: <QueryPlan compiled="true" updating="false"> <GFLWOR type="item()*"> <Let type="item()*" name="$stInstance" id="1"> <DynJavaConstr name="org.stringtemplate.v4.ST" type="item()*"> <Str type="xs:string" size="1">Hello $who$</Str> <Str type="xs:string" size="1">$</Str> <Str type="xs:string" size="1">$</Str> </DynJavaConstr> </Let> <List type="item()*"> <ProfVoid name="prof:void" type="empty-sequence()" size="0"> <DynJavaFunc name="org.stringtemplate.v4.ST:add" type="item()*"> <VarRef type="item()*" name="$stInstance" id="1"/> <Str type="xs:string" size="1">who</Str> <Str type="xs:string" size="1">World!</Str> </DynJavaFunc> </ProfVoid> <DynJavaFunc name="org.stringtemplate.v4.ST:render" type="item()*"> <VarRef type="item()*" name="$stInstance" id="1"/> </DynJavaFunc> </List> </GFLWOR> </QueryPlan> I can see no deviation from https://docs.basex.org/wiki/Java_Bindings#Functions_and_Variables in my code. What am I doing wrong? Thanks. -- Goody Bye, Minden jót, Mit freundlichen Grüßen, Andreas Mixich

Re: [basex-talk] Datamining MS Windows eventlogs converted to xml

Another approach may be to use WinLogBeat and get BaseX to query ElasticSearch.

Call for install/setup stories from users
by Bridger Dyson-Smith 14 Apr '21

14 Apr '21

Hi all - Per the recent thread about installing, I was hoping to convince some of you to share your experiences installing and running BaseX. Whether you use Mac OS, Windows, a Linux, or something else: how are you installing and running BaseX? I'm asking as there could be some possible improvements to the wiki that might help new users (or even less-new users!) get up and running. Thanks in advance for your time and trouble! If I can hear about number of approaches, I'm happy to attempt writing up some details for the wiki. Best, Bridger PS Here's mine: Operating systems: I'm typically using BaseX on either a FreeBSD or a Void Linux system (rarely on other Linuxes, and only once or twice on Windows). Install process: my OS' don't have a pre-packaged download for BaseX, so I do something like: 1. cd ~/bin 2. mkdir basex-src basex-data 3. fetch|wget https://files.basex.org/releases/BaseX.zip 4. unzip BaseX.zip 5. rm -rf basex/src basex/data 6. ln -s ~/bin/basex-src ~/bin/basex/src; ln -s ~/bin/basex-data ~/bin/basex/data ... 7. enjoy basex! Upgrade process: something like 1. cd ~/bin 2. fetch|wget https://files.basex.org/releases/BaseX.zip 3. mv basex basex-old 4. unzip BaseX.zip 5. rm -rf basex/src basex/data 6. ln -s ~/bin/basex-src ~/bin/basex/src; ln -s ~/bin/basex-data ~/bin/basex/data ... Usage note: I have a line in my shell RC file (~/.zshrc) that helps my shell/command line know where to find the various basex executables: `export PATH="$PATH:$HOME/bin/basex/bin"`

Datamining MS Windows eventlogs converted to xml
by Joris Lambrecht 13 Apr '21

13 Apr '21

Dear, For the longest time a good tool to datamine ms windows eventlogs escaped me. BaseX appears to offer the toolkit which could permit to do so after an affordable conversion to XML. Now i seek to build a set of queries to extract information from multiple converted eventlog files at once. Are there people on this list who have experience or are open to building experience on this topic ? Br, Joris
