Subject OJB template enhacement?
Date Mon, 15 Dec 2003 20:06:56 GMT
To all,
	While working with OJB, and using Torque as the generator, I
needed a constant to refer to the fields of the mapped classes when
building criteria for the persistence broker query.  I added a small
block of code to the /templates/ojb/model/Object.vm template to populate
public constants for use in my bl layer.  The code I added as well as my
usage is listed below.  I have been a developer for  many years, and
lately I have been more involved in the java community (although I still
like programming in VB.Net :).  I am a CVS newbie, and don't completely
understand all the implications of CVS usage, but I would like to be
involved in the Torque and OJB projects.  If you don't mind I will keep
playing with things, and send ideas or comments as they arise.

Object.vm excerpt:

public class ${table.JavaName} implements Serializable
  // ---- added here
  #foreach ($col in $table.Columns)
    public static final String FIELD_$col.JavaName.toUpperCase() =
  // ----- end of addition

  #foreach ($col in $table.Columns)
    private $col.JavaPrimitive $col.UncapitalisedJavaName;

AuthUtil.java (usage)

broker = PersistenceBrokerFactory.defaultPersistenceBroker();
			Criteria criteria = new Criteria();
			Query query = new
QueryByCriteria(UserAuth.class, criteria);
			// ask the broker to retrieve the user
authentitcation data
			userAuth = (UserAuth)
			if(userAuth != null) {
				user = getUserByUserAuth(userAuth);
