<message nick="Monky" time="12:09:12.735Z">I cannot change the "owner" and/or "group" of a collection in my db with the java interface</message>

<message nick="Monky" time="12:09:50.587Z">The Interface accepts the change but once i close the interface and open it again everything is back to the old state</message>

<message nick="heathc" time="12:10:28.909Z">Sounds like a file hasnt got write permisions</message>

<message nick="_delirium" time="12:11:47.756Z">its not related to files</message>

<message nick="_delirium" time="12:11:55.406Z">hmm thats weird</message>

<message nick="_delirium" time="12:12:06.141Z">have you checked exist.log on the server to see if an error is logged?</message>

<message nick="Monky" time="12:12:44.353Z">im using exist in the "embedded" mode</message>

<message nick="Monky" time="12:13:37.785Z">Maybe I should tell you more clearly what i do:</message>

<message nick="Monky" time="12:13:56.861Z">I have a empty database with no users (except the default admin and guest)</message>

<message nick="Monky" time="12:14:21.475Z">im connecting to the db with the Java interface (start.jar) with admin user.</message>

<message nick="Monky" time="12:14:32.109Z">I create a new collection - its owned by admin ofc</message>

<message nick="Monky" time="12:14:49.152Z">I then select it, change its properties do owner/group: guest</message>

<message nick="_delirium" time="12:15:04.784Z">that all sounds pretty normal</message>

<message nick="_delirium" time="12:15:11.573Z">which version of eXist?</message>

<message nick="Monky" time="12:15:12.835Z">It looks fine in the overview now but when i close the interface</message>

<message nick="Monky" time="12:15:24.17Z">and connect again its owwed by admin again</message>

<message nick="Monky" time="12:15:25.792Z">version 1.1</message>

<message nick="_delirium" time="12:15:41.554Z">hmm, shouldnt be a problem..</message>

<message nick="Monky" time="12:15:44.658Z">1.1.2dev (4311) to be precise</message>

<message nick="_delirium" time="12:15:49.544Z">are you logging eXist stuff somewhere?</message>

<message nick="_delirium" time="12:16:39.803Z">well i guess you must? I think its required by eXist as a dependency</message>

<message nick="Monky" time="12:17:09.713Z">but im not even using my application</message>

<message nick="Monky" time="12:17:26.356Z">my application tells me "guest user has no writing priviliges" which is correct</message>

<message nick="Monky" time="12:17:48.266Z">but i cannot change that with the java interface that ships with exist 1.1</message>

<message nick="_delirium" time="12:18:22.492Z">well i think that you need to configure log4j - probably as simple as copying the log4j.xml from eXist and Initialising log4j at the start of your app (example code on the log4j site) - then you will get an exist.log and that should hopefully tell you an error or exception</message>

<message nick="heathc" time="12:28:28.725Z">im off to bed, thanks for the help :)</message>

<message nick="Monky" time="12:33:05.431Z">in the exist.log there are no errors</message>

<message nick="Monky" time="12:36:22.058Z">when i read the log correctly the start.jar application does connect to the db, read the data but disconnects right away and changes to the table are not written back to the db?!</message>

<message nick="_delirium" time="12:39:06.772Z">Monky, is there anything in exist.log?</message>

<message nick="_delirium" time="12:39:11.609Z">Exceptions's maybe?</message>

<message nick="Monky" time="12:41:00.076Z">i can produce exceptions when i use the shutdown/connect buttons in the java interfave</message>

<message nick="Monky" time="12:41:15.907Z">but there are non when i just do what i described above</message>

<message nick="Monky" time="12:51:28.81Z">hmm. When i let my application create the collections they are initially owned by guest and everything works fine.</message>

<message nick="Monky" time="12:52:01.134Z">I assume the problem lies with the Java GUI thats included in the exist distribution</message>

<message nick="_delirium" time="12:53:18.389Z">can the user running eXist write to the data directory and the .dbx files?</message>
