Persisting Java Properties

Question

I am currently using OpenLDAP with a Tomcat JNDI Realm to do authentication and to store Java User objects mapped to an InetOrgPerson objectClass and have been doing so for some time in production.
What I would like to do and have been searching for, is to take the Plethora of *.properties files I have in multiple webapps and extend my properties loader to look in OpenLDAP and build the Properties object from values stored in LDAP instead of from the filesystem. The obvious advantage is that for some properties files, each webapp has the same properties file, like the connect info to the content server. If I change the connect info to the content server I want to change it in ONE place, i.e. LDAP, not each and every separate properties file.
In my search I see examples of using serialization to bind a java object to an entry
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://localhost:389");
env.put(Context.SECURITY_AUTHENTICATION,"simple");
env.put(Context.SECURITY_PRINCIPAL,"cn=Directory Manager"); // specify the username
env.put(Context.SECURITY_CREDENTIALS,"password"); // specify the password
DirContext ctx = new InitialDirContext(env);
Properties properties = new Properties();
�
ctx.bind("cn=coolProps,ou=JavaObjects,o=myserver.com ", properties);
This throws an InvalidAttributeIdentifierException on javaSerializedData on OpenLDAP 2.2.29-db-4.3.29 win32 distribution, running on XP Pro.
Even this will be ok as far as it goes but the problem with this is that I would rather have an objectClass schema entry that gave me LDAP modification of the individual properties, so I can use JXplorer (or any LDAP Browser) to manage the properties, just the same as I can modify the properties in the more concrete classes I have mapped. But I do NOT want to create a new schema for every properties file and map each one individually.
Does someone have a Java Properties objectClass schema and java helper example they can/will share? Or is it something I just didn�t manage to find because I didn�t search for the right words?
NOTE* The OpenLDAP Software forum's moderator said this was "off topic" and the latest Open LDAP does NOT include the JavaObject schema.

However I still would like to get a JavaProperties schema if someone has one and some Java helpers to work with it.
