Here is an example, I did it with RC3 here are the steps (as far as I could recollect)

- Download apacheds1.0-RC3
- create a custom schema file myschema.schema

- put this file in E:\Program Files\apacheds-1.0-RC3\src\core\src\main\schema folder
- install maven 2
- open command shell and cd to E:\Program Files\apacheds-1.0-RC3\src\core
- run "mvn process-resources" to generate the myschema schema sources
- generated source files will be found in E:\Program Files\apacheds-1.0-RC3\src\core\target\generated-sources\org\apache\directory\server\core\schema\bootstrap
- create a patch dir somewhere
- copy the generated Myschema* files into patch dir
- build the patch myschema.jar by placing apacheds libraries in classath... a simple javac inside ant will work
- this myschema.jar has to be placed in E:\Program Files\apacheds-1.0-RC3\lib\ext folder
- configure the E:\Program Files\apacheds- 1.0-RC3\conf\server.xml
#=============== add this to server.xml =============================

Great, thanks for the info!  BTW, I'm going to be using an embedded server, once this is built, will it include my new schema in the embeddable server?
 
As for the project, it's a commercial product called Q Pasa!  We monitor and manage middleware software (e.g. IBM WebSphere MQ, IBM WebSphere App Server, and tons of other stuff).  We are planning on using ApacheDS to do our default authentication/authorization to begin with (replacing a legacy, home-grown solution), but we're going to be adding in the capability to find other installations of our software so that disparate installations can be integrated (sort of hard to explain the latter use).  I'm sure if this is successful we'll find lots of other uses for it.  I am evaluating ADS because it is 100% pure java and it is embeddable, not to mention that it's the Apache organization ;-)
 
Again, thanks for the help, I'll let you all know how I progress.

Cheers,
Craig

Great !

Don't worry to much about the mailing list, we don't use user@directory.apache.org atm. So this is the right place to post.

Extending the schema is a little bit complicated in this version, but it does not mean it's complicated.

Here are the steps :
1) create your schema using OpenLdap syntax (which is RFC syntax, btw)
2) put it in apacheds/core/src/main/schema, beside the other schemas
3) go into apacheds/core and modify the pom.xml file :
...
        <configuration>
          <schemaSourcesDir>src/main/schema</schemaSourcesDir>
          <schemas>
            <schema>
              <name>apache</name>
              <dependencies>
                <dependency>system</dependency>
              </dependencies>
            </schema>
            <schema>
              <name>apachedns</name>
              <dependencies>
                <dependency>system</dependency>
                <dependency>core</dependency>
              </dependencies>
            </schema>
...
here, you just add your schema, with its dependencies.
4) now, go back to the root project and compile the project :
mvn install
(it will take around 3 minutes)
5) build the binaries :
cd apacheds/server-installers
mvn install

now, you can install the server with the installer that has been generated.

If you are lost, here is a link to a page which explains the build process :
http://docs.safehaus.org/display/APACHEDS/Building

I think there is something sompler, but I don't know it. Anybody on the list ?

However, if you have any pb, just push a mail. We will help you as fast as we can.

btw, which kind of project are you working on, if it's not secret ?

Hi!

I realize this is the developer's list and that it's a bit early for
ApacheDS, but I'm evaluating it for use in our products.  I'm trying to
figure out how to extend the schema (I need to add a new objectClass),
can anyone point me in the right direction?  I'm fine with reading some
code to understand it.

Cheers,
Craig
