hi Tijs thank u very much for the reply i went through the user guide and i could proceed to some extent.

am struck at one point and it would be helpful if you can provide any ideas on the same.
I have successfully submitted the user form and the variable data is stored in act_hi_details table successfully.
am not able to retrieve the history data from the act_hi_details table.
As per user guide the query is
"historyService.createHistoricDetailQuery()
.variableUpdates()
.processInstanceId("123")
.orderByVariableName().asc()
.list()" which returns List<HistoricDetail>, but am not able to extract form data i.e, variable name and value from the history details.

thanks,
kleyo
