Cannot cast object 'jxl.read.biff.SheetImpl@f55c22' with class 'jxl.read.biff.SheetImpl' to class 'j

Hi,

I'm trying to update the overall status of my tests to an excel which contains a list of services. I want to write the status against the corresponding service name. I'm comparing the data received from the inputFile with the response received from soapUI.I'm writing the status to ServiceFile. I have used the below code but I'm getting cannot cast error at line 25

Code:

def inputFile = testRunner.testCase.testSuite.getPropertyValue("inputFileName")
def ServiceFile = testRunner.testCase.testSuite.getPropertyValue("Service_File")

Workbook inputWB = Workbook.getWorkbook(new File(inputFile))
Sheet inputSheet = inputWB.getSheet(0)
no_of_rows= inputSheet.getRows().toInteger()

{
jxl.write.Label final_status = new jxl.write.Label(2,i ,overall_status)
sheet_writable.addCell(final_status)
}
}
inputWB.close()
list_file.close()

Error:
