Should work.

this sounds VERY strange, are you sure, that you execute your methods
inside a transaction (i.e. the transaction attributes set to
Required, RequiresNew or Mandatory). If so, could you please
put debug output in the ejbLoad() and ejbStore() and some test methods
of a test bean and verify, that ejbLoad() really is called before
every business method as given in the following diagram:
All methods declared as TX 'Required'!

Setting the <debug> option to true in (standard)jaws.xml will
show the get_state/put_state SQL.
Another thing to note is: without true XA compliant JDBC drivers
there will be no DB locks set when reading data from the DB, thus
another app may change the DB in the time between get_state and
put_state, resulting in synch errors. You might want to set
the <select-for-update> option in jaws.xml or standardjaws.xml
to true, see http://www.jboss.org/documentation/HTML/ch05s03.html.
