LDAP: Recommended way to add new objectclass to existing entries?

Can anyone help me with the preferred way to add a new objectclass (with attrributes) to existing entries within a directory (via the javax.naming API)?

I have an application that uses a directory of users. Each user has objectclasses "top", "person", and "inetOrgPerson" with usual attributes.

The application needs to change to add a custom objectclass, say "ourAppClass" (and its attributes), to each existing entry within the directory. I have already successfully defined the schema for the objectclass within the directory.

I cannot find examples showing how to add an objectclass to existing entries. Creating brand new entries with custom objectclassess is straightforward.

When using DirContext.modifyAttributes must I define all the objectclasses again, or is there a way to send only the new objectclass and its attributes only?



Does someone have a good example to follow?

I think I have answered my own question. I think I need to use a ModificationItem to add an attribute to the objectclass.

 
It is sorta covered in the JavaRanch Style Guide.
