Getting IllegalArgumentException

[noonmati]

Hi,
I am trying to integrate my reports with my java web application. There are three parameters that i need to pass to the .rpt to generate the report. Now problem here is, everytime try to create the report using crystalreportviewer, i get an IllegalArgumentException. And interestingly, the stack trace does not show where exactly the wrong value is passed.
Here are the parameters passed.

Date : Datetype >> Range >> "yyyy-MM-dd"
ID : Integer >> Discrete >> Multiple
SortOrder : String >> Discrete >> Non-Multiple

CR Version : XI

Please help me out to know where exactly I am wrong.

Thanks,
Rajib
