Convert a date format to Java

I have a method to parse from an xml in the form of a string, to a Request object. But in the xml the date comes to me like this:

2009-06-12T00: 00: 00 + 02: 00

Then I do not know what format to give the SimpleDateFormat to be able to convert that to Date. That would go inside the parenthesis in:

SimpleDateFormat formatter = new SimpleDateFormat("");

When I execute the method I get the following error:

Unparseable date: "2009-06-12T00:00:00+02:00"

I write the method below:

public Date convertirFecha(String s) throws ParseException{
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
        Date fecha = formatter.parse(s);

        return fecha;
    }
