How to send data from Excel to mysql using java also normalizing it at java level (no replies)

I have a data sheet in excel with 19 attributes
I am building a web based application using flex as front end
java middleware
and mysql as backend
Now the issue is there would be a browse tab to upload a custom excel sheet
i need to transfer it to mysql
apart from that i need to normalize that table too using java itself
any one can help on how to go about doing this

Thanks in advance
