Hi all,
I wonder if anyone can help. I'm developing a web-based application on
jboss2.2/castor0.9.3/tomcat3.2/MSSQLServer7.0 based roughly on the "rooms"
example from the jboss site (stateless session beans, using a DAO class,
using castor), and am making pretty good progress. Most of the things I have
tried have worked seemlessly - dependent objects, nested attributes, long
transactions etc. However I'm running in to a problem when I attempt to load
objects that have been populated via direct db access with sql. For example,
if I populate the Orders table with a dozen orders using sql, and then try
to load anyone of the orders via castor I get the following exception.
[CastorJDO] java.lang.IllegalStateException: Transaction
org.exolab.castor.jdo.engine.TransactionContextImpl@5e293a does not hold the
read lock: net.ereed.order

I've tried a couple of things - I've turned off caching for the class
net.ereed.orders.ARRDOrderData and set the access type to db-locked in the
mapping file,in which case I don't get the above exception, but instead
[CastorJDO] org.exolab.castor.jdo.PersistenceException: Object,
net.ereed.orders.ARRDOrderData/1001, isn't loaded in the persistence
storage!

For orders that I create directly via my orderservice (using castor) I have
no problem loading/updating/removing them. I know I am being very dumb
somewhere, but I don't know where.
Any help greatly appreciated.
Thanks, Jon.
