Thanks Marco, I understand. As an aside for others, a GO edge router with BaseX is another option - say https://github.com/thomseddon/traefik-forward-auth. OIDC, ACME and SSL are all built in. BaseX can trust / check the forwarded cookie as part of BaseX permissions checking. https://docs.basex.org/wiki/Permissions Adam On Mon, May 3, 2021 at 6:00 PM <basex-talk-request(a)mailman.uni-konstanz.de> wrote: > Send BaseX-Talk mailing list submissions to > basex-talk(a)mailman.uni-konstanz.de > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.uni-konstanz.de/mailman/listinfo/basex-talk > or, via email, send a message with subject or body 'help' to > basex-talk-request(a)mailman.uni-konstanz.de > > You can reach the person managing the list at > basex-talk-owner(a)mailman.uni-konstanz.de > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of BaseX-Talk digest..." > > > Today's Topics: > > 1.

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

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
