You can also set the persistence types in orion-ejb-jar.xml.
The easy way to do this: deploy, let orion autocreate the tables; then
copy $ORION/application-deployments/[your app]/[your ejb
dir]/orion-ejb-jar.xml to an /orion dir in your EJB dir... hmm, man, that
sounds awful. It's a lot easier to show than it is to explain.
Let's assume your application is /projects/appA, called "appA," and your
EJB is in a directory,
appA/myejb. In that case, you'd copy
/usr/local/orion/application-deployments/appA/myejb/orion-ejb-jar.xml to
/projects/appA/myejb/orion/orion-ejb-jar.xml.
Now modify the copy in appA/myejb/orion/orion-ejb-jar.xml to include the
persistence-type attribute.
Whew! Now you delete the deployment directory and destroy the tables
created for the EJBs (the tables with the default attribute sizes.)
Redeploy; it'll now use the persistence types from the orion-ejb-jar.xml.
