Methods

o pref_reg_lookup 
 public pref_rep pref_reg_lookup(pref_req req) throws RemoteException
The RMI interface -- very similar to the other pref_reg_lookup call. This one used the serialized objects pref_req and pref_rep and hence has higher overhead.

o pref_reg_lookup 
 public String pref_reg_lookup(String requestStr) throws RemoteException
The RMI server routine called by clients. This implements the front end interface to the clients. This calls the back end to get the preference script and executes the script to get the preferred end point.

o load 
 public String load(String dnStr,
                    String script) throws RemoteException
This RMI call installs a new script for the user name given. There is no authentication done. The input is the unique-id of the user given as a DN string, and the pref-script given as a string as well. The output is a "ok: ", or a "failed: ".

o destroy 
 protected void destroy()
Called by iSpace

Overrides:
destroy in class iSpaceService
o init 
 protected void init(iSpaceServiceConfig config)
Called by iSpace

Overrides:
init in class iSpaceService
