You can reverse engineer a PDM from a database that contains Java classes and also reverse the Java classes into an OOM. The Java abstract data types in the PDM are automatically linked to the Java classes in the OOM as follows:
You should reverse engineer the Java classes in the database that are used as data types for the columns and domains in an OOM
Then reverse engineer the database into a PDM
PowerDesigner automatically searches the open OOM for the Java classes that correspond to the JAVA abstract data types in the PDM and makes the corresponding links
The Java classes that are reverse engineered into the PDM are created automatically as abstract data types of type JAVA.
You can access the properties of these Java classes from the property sheets of the corresponding abstract data types in the PDM. For more information, see Linking an abstract data type to a Java class.
