ISessionMgr.logon not working with cluster name

Hi, we are trying to get our software to work properly in a clustered environment.  We use Business Objects credentials in three places:

1. On the COM SDK that automates Universe Designer to create and modify Universes (Designer.Application.Logon)

2. In the .NET enterprise SDK where we create roles and folders on the server (CrystalDecisions.Enterprise.SessionMgr.Logon)

3. In the Java SDK where we create reports (ISessionMgr.logon)

In the first 2 cases, the SDK's are accepting credentials of the form ("myUsername", "myPassword", "@myClusterName", "secEnterprise").

However, the Java SDK appears to only accept credentials of the form

("myUsername", "myPassword", "myNodeName", "secEnterprise").

where "myNodeName" is one of the nodes on the cluster.

Is there a workaround here?  Do we need to enumerate the cluster members somewhere and arbitrarily choose a node on the cluster to pass to the Java SDK? Or is there a better solution?

Thanks, Eric
