Hi,
Is the following a typo?
When packaging these Beans, don't forget to include the files ejb-jar.xml
and jboss.jar in the directory META-INF.
^^^
Also, there is a warning at the bottom of the page:
Note that it can be very difficult to change the number or names of
columns in the table once there is data in it. JBoss gets very confused
by this, as you would expect. When a CMP Bean is re-deployed, JAWS tries
to write into its table all the data it had in its last deployment. If
the table has different columns it probably won't be able to do that.
This means that it is important to get the persistent fields thoroughly
correct before starting to put real data into the application.
After reading the "Customizing JAWS" section, it would seem more appropriate
to suggest using "jaws.xml" and dropping the table by undeploying the EJB
if a data change is necessary. Being correct before you start is nice
but not without its drawbacks, even for the experienced programmer! Or am
I missing something?
