[jira] Created: (CAY-1314) Migrate Modeler Preferences to Java
Preferences API: migrate org.apache.cayenne.modeler.ModelerPreferences
Migrate Modeler Preferences to Java Preferences API: migrate org.apache.cayenne.modeler.ModelerPreferences
----------------------------------------------------------------------------------------------------------
Key: CAY-1314
URL: https://issues.apache.org/jira/browse/CAY-1314
Project: Cayenne
Issue Type: Task
Components: CayenneModeler GUI
Affects Versions: 3.1
Reporter: Andrus Adamchik
Assignee: Olga Tkacheva
There are multiple problems with the current Cayenne Modeler preferences mechanism (e.g. CAY-466)... The main problem I guess is that HSQLDB does not provide a way for concurrent reliable access to a prefs DB file. There were suggestions to switch to H2, still I am in favor of not rinventing the wheel and just going with java.util.prefs. Among other things that would allow us to share preferences between CM and runtime framework, specifically to easily use the JNDI hack (http://cayenne.apache.org/doc/using-jndi.html) without the need to include the modeler jars in the application..
As a first step I suggest that we convert the old org.apache.cayenne.modeler.ModelerPreferences (that is not even using HSQLDB) to use Preferences API. This will still leave room for rollback of this whole idea and will let us try built-in Java prefs mechanism before we fully commit to it.

Yep, this is one of the consequences of the HSQLDB database access
model we've been using till now.

Re: [jira] Commented: (CAY-1314) Migrate Modeler Preferences to Java
Preferences API: migrate org.apache.cayenne.modeler.ModelerPreferences
Posted by Michael Gentry <mg...@masslight.net>.
I've been experimenting with the Java Preferences feature and it seems
fairly reasonable to use so far. The biggest pain (so far) is
handling to-many types, but I just loop through them adding a .0, .1,
.2, etc to the names of the keys for that.
