    InputStream stream ;
    try 
        {
        stream = new java.io.FileInputStream( "/path/to/file" ) ;
        }
    catch (IOException err)
        {
        throw new RuntimeException(err) ;
        }

Sorry, I do a lot of Java at work.  However, you are right that Java's
I/O API is overly cumbersome to work with.  

How about
    s = zapi.dateformatshort(request, date)
?

def dateformat(request, date, length) :
    formatter = request.locale.dates.getFormatter('dateTime',  length)
    tz = zope.interface.common.tzinfo.ITZInfo(request)
    return formatter.format(zope.i18n.switchTimeZones(date, tz)

def dateformatshort(request, date) :
    return dateformat(request, date, 'short')

def dateformatlong(request, date) :
    return dateformat(request, date, 'long')

I agree with this.
