Hi Anter,

What version of BIRT are you using? If it was january, you'd want the defaults to be 2010-01-01 and 2010-01-31? Is this correct?

Unless something has changed in recent versions of BIRT, I'll recommend the same thing I always do. just create your two date parameters, and use an external parameter page to call your report. There isn't a real easy way to assign default date parameter values without modification. It can be done, but they won't show up in the parameter dialog in the BIRT viewer.

Anter, 
 
This devShare post may help you with that by using a scripted dataSet:

Thanks Michael,
I wrote 2 scripts, first for begin of current month:
_____________________________________________
var today=new Date();
var day=today.getDate();
DateTimeSpan.addDate(today,0,0,-day+1)
_____________________________________________
and second, for the end of current month:

var today=new Date(); var t=today.getMonth(); var day=today.getDate();
var i=31; var j=30; var l=28;
var m=i-day; var n=j-day; var b=l-day;
if ((t==2.0) || (t==4.0) || (t==0.0) || (t==6.0) || (t==7.0) || (t==9.0) || (t==11.0)){
DateTimeSpan.addDate(today,0,0,m)
} else if ((t==3.0) || (t==5.0) || (t==8.0) || (t==10.0)){
DateTimeSpan.addDate(today,0,0,n)
} else { DateTimeSpan.addDate(today,0,0,b) }
______________________________________________

How I can now set the default these parameters, using written scripts?

Anter,

The way that the one in the example was done was by using a combo box type parameter. You could either use the default date, which was the end of the month, or you could select the text entry and enter your own date. If this way is not acceptable, John's suggestion is probably going to be the way to go. In 2.5.1, the default value can be set using javascript syntax. This new feature should allow the setting of the parameter to the last day/first day more easily. However, that would require you to upgrade from 2.2.2, which may not be an option for you.

Thanks Michael, you help me again!
