I have an interface where the user selects the values and upon clicking the download button the selected values runs in the sql query and the obtained data is written to csv file.--
I am doing an RPC call to send the user selected values from the interface to the server. And on the server side I am storing these values in the http session variable. And I am retrieving these values in the servlet class which has a funtionality to write a data to csv file. Because the values send to the server is a RPC call, my initial session value remains zero ( first download click) and it writes nothing to the csv file though i have selected values from the user. On second click of download button it writes the data of the first selected values. How can expedite the RPC call or how can I make a RPC to synchronize call ? Can someone please suggest a possible to overcome this? Thanks a lot in advance
