Is there any way to generate hibernate mapping files and Java classes from entity in Logical model of oracle data modeler? or is there any tool which work on data model export/DDL to create classes.
I know we can generate classes from eclipse/Netbeans using database table but I am looking for something which can read oracle data modeler file/export instead of database(we have huge number of branches in svn for data model)
You can export the design to the reporting schema. Then you have the whole design in Oracle database tables. On these tables you can let a plsql or java program generate the mapping files and java classes.
The reporting database is not really documented, but it is not hard to find the data. The generating of the mapping files and java classes is not much harder than filling in a template with data of the reporting database.
