I do something similar, but continue to use Spring (it wires nearly everything together, so I must, and it's good to use) and JNDI to get a handle for my datasource. No changes to my code. IIRC, all I had to do was change my spring applicationContext.xml to use "classpath:hibernate.cfg.xml" as the value of "configLocation" (on my org.springframework.orm.hibernate3.LocalSessionFactoryBean), put the same hibernate.cfg.xml file on my classpath when running my j2se code, and provide the JNDI environment and datasource with simple-jndi (from http://www.osjava.org/simple-jndi/) instead of Tomcat. I'd be happy to provide more details if anyone wants; configuring simple-jndi took me a little while.

  I think this would be a good addition, so post if you please. :)
  
  Thanks.

  To get spring working, follow my comments above, and also the j2se app needs something like this to load the spring application context(s):
  
public class MyDataLoader {
protected AbstractApplicationContext ctx;
public static void main(String[] args) {
new MyDataLoader(args).load();
}
public MyDataLoader(String[] appContextFiles) {
super();
ctx = new FileSystemXmlApplicationContext(appContextFiles);
}
...
}

  
  To provide a JNDI environment with simple-jndi all you have to do is put the simple-jndi jar file in the classpath and a jndi configuration dir (e.g. ${user.home}/test-jndi) on the classpath. In ${user.home}/test-jndi create jndi.properties:
  
java.naming.factory.initial=org.osjava.sj.SimpleContextFactory
org.osjava.sj.root=file:///c:/Documents and Settings/myUserID/test-jndi/jndi-entries
org.osjava.sj.delimiter=/
org.osjava.sj.colon.replace=!

  And create ${user.home}/test-jndi/jndi-entries/java!comp/env/jdbc/myDataSourceName.properties
  
type=javax.sql.DataSource
driver=net.sourceforge.jtds.jdbc.Driver
url=jdbc:jtds:sqlserver://host:1433/databaseName;SelectMethod=cursor
user=myUsername
password=myPassword

  
  Don't forget to put other container-provided jars that you may need (e.g. your jdbc driver) on the j2se app's classpath.
