There are several options.

 * In your ice.config file you can set omero.group to the group id that you want to be logged into. 

 * You can pass omero.group in to loadOmero:

>> p = java.util.Properties();
>> p.setProperty('omero.group','your-group');
>> p.setProperty('omero.host','localhost');
>> p.setProperty('omero.user','root');
>> p.setProperty('omero.pass','SECRET');
>> [c,s] = loadOmero(p);
>> s.getAdminService().getEventContext().groupName
 
ans =
 
default
 
 * You can call session.setSecurityContext after logging in:

>> import omero.model.ExperimenterGroupI
>> s.setSecurityContext(omero.model.ExperimenterGroupI(0, false));
>> s.getAdminService().getEventContext().groupName
 
ans =
 
system

 * Or you can use s.getAdminService().setDefaultGroup(experimenterObj, groupObj);

which will change persistently which group you log-in as if no "omero.group" value is passed, just as if you had made the change in, say, WebAdmin. However, that shouldn't be done overly frequently, so it's probably best done in one of the UIs.

Once you are logged into a group that is collaborative, service methods will begin returning shared data as well as your own, unless the JavaDocs specifically state that it's a method which returns only your own data.
