Reading Excel file through the Generic Java Driver

All,

I am wanting to receive an Excel file through the Cloverleaf server and then open that file with the Generic Java Driver.  I’ve created the code that will open an excel file, but what we get on the Cloverleaf side is either a binary encode string or a byte array.  Anyone ever done something like this?  Just need to somehow get the message data into a format that can be opened by the Apache POI XSSFWorkbook class.

Thanks,

Jerry
