mixupdates first experiments
by Marco Lettere 16 May '14

16 May '14

Hi all, we are rather interested in experimenting with the new facility provided with the latest snapshot mixupdates. I have a question related to the scope of the mixupdates option. For us (using the GUI) neither declaring the option at module level with declare option db:mixupdates 'true'; nor inlining it with a pragma as in declare function local:sample() { (# db:mixupdates 'true' #){ let $d := <a><b></b></a> return (replace node $d/b with <d/>, "Success") } }; prevent the compiler from complaining with: "... all expressions must be updating or return an empty sequence". Instead it works neatly when the option is set in the .basex file. Is setting the option globally for the whole basex instance the only way to enable the compiler for mixed updates? Regards, Marco.

Rest Access from javascript using AngularJs
by Yoann Maingon 15 May '14

15 May '14

Hi, After xmlprague and my presentation at the BaseX user group I was told (and I agree) that it wasn't really smart to use php for what I was building as it had almost no added value as I could directly query basex using the Rest Interface. Does anyone as some example using either angularjs or jquery ? I think I'm struggling with the login. Even just trying with a Rest test tool, I can see that I have error messages in Basex telling me theat access was refused. Yoann Maingon CEO - mydatalinx +33664324966

Sorry, not doing this on purpose. Running test2.xq triggers runtime-error, see attachment: basex errorMessage.txt When using: declare function local:go ( $parentItem ) { ( $parentItem , for-each( $parentItem/child::* , function( $childItem ) { local:go( $childItem) } ) ) } ; All runs fine.

Deploying a BaseX Web application... (beginner question)
by a.bouchet＠no-log.org 09 May '14

09 May '14

Hello, Thanks to the developers for the excellent database software. I love basex having used it on windows desktop for some little database-driven projects, but now, I'd like to deploy it in the context of a web application, if possible. So I read everything I could find about the topic but didn't find a step-by-step guide of how to accomplish it. I'm not familiar with java, but I tried to deploy the downloadable BaseX war application on Appfog services, and also using Openshift with Tomcat 7. On Appfog, the process of installing the war file (which seemed to be straightforward) didn't complete and generated a java console error. (cf http://stackoverflow.com/questions/12283448/deploy-simple-java-web-applicat…) And on OpenShift, the process of uploading the war file succeeded, the console stating that the build was successful, but when going to the URL of the application, the server generates an internal error HTTP status 500... (cf https://www.openshift.com/kb/kb-e1088-how-to-deploy-pre-compiled-java-appli…) From there, I don't know what to do next, but would really like to get a basex web app up and running and interacting with it through the HTTP REST API. Thanks for any help in this regards. Aurelien
