Ok, I've searched high and low and still have not found a solution to this problem. Using both JBoss 2.4.4 and JBoss 3.0RC3 I'm getting a Load failed NullPointException.
I have 4 beans, one of them works like a charm, the other 3 produce this error. Everything is configured properly in jaws.xml and ejb-jar.xml. None of them have null fields, all the fields are mapped to java classes Integer, java.util.Date, String, or java.sql.Timestamp. I'm running this on Windows 2000 with SQL Server 2000.

Please, I need help, this is really holding up the development of our app.

Thanks in advance,
Jason
