I've created a local Apache Derby
database in Netbeans, but am having problems when I try and autogenerate the POJO files, using the "Hibernate Reverse Engineering Wizard".
My Hibernate configuration (generated by Netbeans from the
database connection, then I added a few bits):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Default Netbeans generated parameters -->
<property name="hibernate.connection.driver_class">org.apache.derby.jdbc.EmbeddedDriver</property>
<property name="hibernate.connection.url">jdbc:derby:C:/CerealDatabase</property>
<property name="hibernate.connection.username">cerealuser</property>
<property name="hibernate.connection.password">cerealpass</property>
<!-- Additional parameters -->
<property name="hibernate.dialect">org.hibernate.dialect.DerbyDialect</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.default_schema">CEREALUSER</property>
</session-factory>
</hibernate-configuration>
When I try and generate the POJOs using this configuration file, I get the message to check my configuration file, and the derby.log gives the errors:
java.sql.SQLException: Failed to start
database 'C:/CerealDatabase', see the next exception for details.
Caused by: java.sql.SQLException: Failed to start
database 'C:/CerealDatabase', see the next exception for details.
Caused by: ERROR XSDB6: Another instance of Derby may have already booted the
database C:\CerealDatabase.
I've closed any other connections to the
database before trying this, and there is no "db.lck" lock file at the time, which indicates there are no connections to the
database as I understand it.
Does anyone have any ideas? Help gratefully received.
