I can't get Hibernate to disconnect from the database once it is connected.
It creates a HSQLDB.lck file and I have to terminate the Tomcat before I can
access it again.
I have tried: (With no luck..)
try {
Configuration cfg = new
Configuration().configure("/hibernate-HSQLDB.cfg.xml");
SessionFactory sessions = cfg.buildSessionFactory();
Long user = new Long(0);
AuditInterceptor aii = new AuditInterceptor(user);
session = sessions.openSession(aii);
sw.start();
list = session.find("from " + table + " in class " +
StringUtils.capitalise(table));

// trying to get HSQLDB lck to release...
if(session != null && session.isOpen()) {
Connection con = session.connection();
Statement st = con.createStatement();
st.execute("SHUTDOWN COMPACT");
con.commit();
st.close();
con.close();
logger.trace("Shut down HSQLDB session!");
session.disconnect();
if(session != null) session.close();
}
hibernate.push(list.toArray(new Object[list.size()]), clazz);
} catch(Exception e) {
throw e;
} finally {
try {
if(session != null && session.isOpen()) {
logger.trace("Closing CSV session!");
session.disconnect();
if(session!=null) session.close();
}
} catch(Exception e) {
logger.trace("Error trying to close session");
throw e;
}
}
but just get:
