[EJB:011076]Unable to deploy the EJB 'OrderARSLineItemEJB' because the database
table 'orderlineitems' is not accessible. Please ensure that this table exists a
nd is accessible.

This killed me.. I had put an extra ‘ ‘ before the name of my MySQL table orders…

[EJB:011019]While reading META-INF/weblogic-cmp-rdbms-jar.xml, the persistence l
ayer of the Entity EJB failed to deploy. The error was:
Error in descriptor line 50: Error parsing file at line: 50 column: 25. org.xm
l.sax.SAXParseException: The content of element type "weblogic-rdbms-bean" must

automatic-key-generation?,check-exists-on-method?)"..

You get this message if you play with certain field and delete them from
weblogic-cmp-rdbms-jar.xml

The first time I ran the final program it gave these messages. When I ran it again
İt was OK, it may be related to two extra records in the ordrs table which did not have any
Line items???
