Find an account or SLA that meets the service's requirements. This is a wrapper around getBillingHeader(EndpointReferenceType[], StorableInStateRepository) which first queries the service to find out what it needs.

Parameters:

service - the service to be used

Returns:

the EPR of a suitable management resource, or null if none is required

Throws:

NoSuitableAccountException - if no suitable resource is available

RemoteException - if we tried to contact a local management service for help and it failed in some way

public org.apache.axis.message.addressing.EndpointReferenceType getBillingHeader(org.apache.axis.message.addressing.EndpointReferenceType[] possibleServices,
                                                                                 StorableInStateRepository service)

Find an account or SLA that meets the service's requirements. The service trusts possibleServices. Pick one where we have and account and return the account.

This will contact the a client management service for an EPR if available, or will choose one from the local repository otherwise.

Returns:

the EPR of a suitable management resource, or null if none is required

Throws:

NoSuitableAccountException - if no suitable resource is available

RemoteException - if we tried to contact a local management service for help and it failed in some way
