Subject [jira] Commented: (DIRSTUDIO-232) DAO Generator

David Jencks commented on DIRSTUDIO-232:
----------------------------------------

There are also numerous efforts such as jdo, jpa, hibernate, OJB, ...... that attempt to provide
POJOs with rdbms backing.  That may not be a lot harder to implement and perhaps would be
a lot easier to use.

In my triplesec branch I developed something conceptually related to JPA or JDO to provide
POJO like data objects backed by ldap.  Its fairly flexible but currently requires you to
write the classes by hand.  I don't think it would be all that hard to write an enhancer to
modify pojos to be backed by a system like this.

maven project including the code:
https://svn.apache.org/repos/asf/directory/sandbox/djencks/triplesec-jacc2/admin-api2

package:
org.apache.directory.triplesec.admin.persistence

> The Data Access Object (DAO) design pattern offers a method for seperating the access
to data from the underlying data stores. One of the disadvantages of this patter is, that
the implementation requires a lot of code to be written.
> There already exists some code generators which generate java code for accessing data
from RDBMS according to this pattern. For example: http://mdaog.sourceforge.net/.
> It would be quite cool to add such a DAO code generator to Studio for accessing data
from LDAP servers.
