Re: [JBoss-user] LDAP as CMP backend?
I don't know where it is but someone mentioned that there is an sql/jdbc way of accessing ldap. If this really exists, you can wrap that driver in one of the jca-jdbc wrappers (probably the local tx one) and use it like any other datasource with cmp. If you do this I'd appreciate your contributing details of how, especially the datasource configuration (ldap-service.xml or ldap-ds.xml for 3.2/4). If ldap does not support transactions you may need to be careful if you write or update information that your writes always succeed;-) david jencks On 2002.08.26 21:19:41 -0400 Curt Johnson wrote: > Holger Baxmann wrote: > > >AFAIK, matrix2 should provide valueable :) improvements for the > persistence > >manager, including interceptors, detyped invokers on mbean level. so, > then > >you may have serveral impl's for the persistance layer independend from > the > >ejb container 8-). there should then ejbql working with hierarchical > data, a > >parser for i.e. ldap dn syntax presumed. > > > >but, what is your objective? you want to have transactions, security ... > ? > > > I want to store app data in LDAP like users and such.

In the same way that you would use an RDBMS. For instance I can have my users conform to the inetOrgPerson schema in LDAP then have a my entity beans do operations to the LDAP server rather than the database. It's essentially a way to have application potability in the data layer. For instance, one application I'm working on has a list of vendors for our company, we also want a CRM application.

AFAIK, matrix2 should provide valueable :) improvements for the persistence manager, including interceptors, detyped invokers on mbean level. so, then you may have serveral impl's for the persistance layer independend from the ejb container 8-). there should then ejbql working with hierarchical data, a parser for i.e. ldap dn syntax presumed. but, what is your objective? you want to have transactions, security ... ? what is different from using the federated namespace in jndi for this job ? thanks bax but, whats your - Original Message - From: "Curt Johnson" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, August 26, 2002 11:50 PM Subject: [JBoss-user] LDAP as CMP backend? > Hi guys, I was wondering if anyone had used LDAP for the backend for CMP > entity beans. > Does the CMP engine in Jboss support this?

[JBoss-user] LDAP as CMP backend?
Hi guys, I was wondering if anyone had used LDAP for the backend for CMP entity beans. Does the CMP engine in Jboss support this? I'm looking for something like Castor's DAX but for CMP. Is this a planned feature? Should I put in a feature request? Any pointers to information would be greatly appreciated.
