obviously i know what causes the exception.
data type is defined as date, my java object is Calendar (which contains a date)
so is there a way to tell birt it shall call .getTime() on my calendar object to gain the date?
some sort of Converter / Dataprovider which converts like:
public static Date toDate(Calendar cal) {
return cal.getTime();
}
as this would resolve the issue...

In the binding expression you should be able to add something like:
importPackage(Packages.java.util);
var mydate = yourcalobject.getTime();
