Hi,

tWebServiceInput component is generally used as a Start component. Could you please use tWebService component in your work flow instead to see if it works?

Best regards

Sabrina

first run it debug mode and check all 7 variables

if debug mode will not print variables - add second FixedFlowInput component and print (tLogRow) them manually

I ran in debug mode also,7 variables are displayed at fixedflowoutput.and the webservice component is giving null .

I tried to use advance java option in webservice component and use System.output.ptinln to check if the values are reaching that component thru tflowiterate.it displayed correctly all the 7 variables.but the output from webservice is null.

After changing JRE and JDK settings,the exception turned out to be as output as null.
