Hi Ian,

the only way to know whether or not the client will connect to the given server is to call createSession. If you call loadOmero with more than one return argument, however, createSession will be called for you:

 properties = java.util.Properties();
 properties.setProperty('omero.host', 'localhost');
 properties.setProperty('omero.user', userName);
 % etc.
 [client, session] = loadOmero(properties);
 % similarly with passing an Ice.Config file.

Cheers,
~Josh
