adding users to organizational units using java in googleApps

i am looking for a java code sample that explains on how i can add a user to an organizational unit. i added several units and now i would like to move the uses to the appropriate unit. in 开发者_JAVA百科addition it would make life easier, if i also can retrieve all existing units with somthing like getOrganizations()

thanks thomas

Here is a sample client I wrote:

This client provides samples for all possible organization unit management operations including retrieveAllOrganizationUnits and should be used with GData Java library which can be found here: http://code.google.com/p/gdata-java-client/downloads/list
