I am making a tender management system in which i m preparinig a GUI in java which writes the data in excel and reads the data from excel. I want to connect the excel add-in named solver with my java program so that when i click the respective button solver gets called and my neccessary operation will be performed.

as per my knowledge we can read and write the data in msexcel with the help of JExcel API or Apache POI in java but i want to access the the excel add-ins with the help of button in java. Can anyone tell me how to do it.
