To define automatic table creation:
In the weblogic-cmp-rdbms-jar.xml file, set the create-default-dbms-tables element to True to explicitly turn on automatic table creation for all beans in the JAR file. Use the following syntax:
<create-default-dbms-tables>True</create-default-dbms-tables>
Specify the correct database system or database vendor name in the database-type element of weblogic-cmp-rdbms-jar.xml. CREATE TABLE syntax and datatype mapping is provide for the following database-type values: INFORMIX, ORACLE, POINTBASE, SQL_SERVER, and SYBASE. All other DBMS systems use a basic syntax and the datatype conversions shown in the table above.
