I have problems associated with Hibernate/JPA using an Apache Derby embedded database and hope somone might provide some pointers on how I might diagnose what is going on.
I might have multiple problems interferring with each other but my first concern is that changes to the database (adding rows) do not seem to appear when I inspect the database using DbVisualizer tool (DvVisualizer Free 9.0.8). I use that tool because NetBeans IDE Database services cannot be used to inspect Embedded Derby databases (only server databases - not what I want to use).
EDIT: I finally was able to configure the database service in the IDE to allow me to inspect the data within the IDE, so I don't need to use the DbVisualizer tool anymore.
My test is a NetBeans Platform (RPC) application using NetBeans version 7.3.1, Apache Derby verson 10.3.2.1 and Hibernate 4.0.2 Final.
I suspect I need to include in my application a Shutdown command, but I have not been able to make that work. The issue with the Shutdown might be related to how to access that in NetBeans Platform applications. I am using Entity Manager (not Session manager) When I try a shutdown, I always get this exception:
Code:
java.sql.SQLException: No suitable driver found for jdbc:derby:hibernatejpa-db;shutdown=true
I tried adding the full path to the database directory in the shutdown command and to use the URL of just "jdbc:derby:" (omitting the database) which should shutdown the Derby engine (I think) with no change to my symptoms. The application sets the System Property for Derby_Home, so just giving the database name to Derby should work - Right?
After running - exiting my application the database directory has the files: "db.lck" and "dbex.lck". It is my understanding those files should not exist if the database is shutdown correctly - Right? When I was using HSQLDB that was true, but I have not been able to find out if that is also true for Derby.
EDIT: Another problem is that I don't see a traditional LOG file for Derby activities. There is a Log directory with three files in it, but I cannot view the contents (in a text editor, such as GEdit). I expected to see a file named derby.log, but I have instead: "log.ctrl", "log1.dat", and "logmirror.ctrl". Should I have a traditional log file viewable with a text editor/viewer program?
The database is setup in the Installer class of a NetBeans Module named Controller - contents below:
Code:
/*
* MyDBTest Application - Controller Module - Installer class
* Controller Module life-cycle processing
* Simple DB initialization test

BUILD SUCCESSFUL (total time: 53 seconds)
I cannot seem to add screenshots to this post. I took screenshots of DbVisualizer showing the data and also my application window shing the data in the database and they do not agree. I am sure both have the same path to the database - so they should agree.
Does anyone have any ideas on what might be wrong, or what information I can provide to help figure out what is going on?
Thanks for your time,
Jim
