Hi Weijian,
In case you are still interested,
I'll be publishing a new revision
of the DAS LDAP Design Guide in a few days.
This is written as a cook book for how
to write the DAS, so it should be fairly straight
forward to follow.
Also - Apache Tuscany is very supportive
of this approach (We've had many discussions already)
and the project will
likely be moved into Tuscany as soon
as the initial implementation is complete.
I could have a working implementation
right now that reads and writes data graphs,
but there are a few bugs in the ADS
Dynamic Schema capabilities that need to be cleared
first. As soon as that's done I'll commit to
having an implementation that reads and writes SDO DataGraphs
within 10 days.
Note that SDO DataGraphs are really XSD Instances
and SDO was designed to use XML Schema for Typing.
Cheers,
- Ole

Hi Weijian,
As others have already confirmed such a tool does not exist in
totality. There
were some efforts out there with partial support for such functionality.
Spring LDAP (not really but handles some glue code)
Hibernate LDAP (incomplete)
Castor LDAP (some say it is complete but I have not tried it)
BTW it would be nice to start such an effort here. There are several
interesting
approaches one of which was mentioned by Stefan Zoerner regarding he use of
Object and State factories for JNDI. I thought heavily about this a
while back however
there are some issues with using OF and OS namely in the area of
managing references
in an object graph. I think the DAS stuff Ole spoke about has potential
however
the timeline is unknown and we only have one person looking into it at
the moment.
If enough people are interested I think we can find a solid approach
with a visible
timeline to implement such a Object-LDAP (OL) mapping tool.
HTH,
Alex

Hi,
Is there a tool to convert LDAP data to Java bean based on LDAP
schema? What I want is quite like what JAXB does on XML. Given an XML
schema, JAXB is able to generate Java classes that translate schema
compliant XML to Java beans and back. Now I have a LDAP schema, and a
LDAP server where data complies with the scheam. I need to read LDAP
data and conert to Java beans. I can do this manually. But if there is
a tool able to automatically generate the code based on the LDAP
schema, it wiil be great!
Is there such a tool? Any hint? Thanks a lot!
Cheers,
Weijian
