Database Software

i'm using JAVA shapefile converter (11g R2)

i want correct steps to convert it successfully
i converted some shapefile but sometimes it show exceptions
( as example if shapefile has arabic fieldname )
i want to handle all expected exception
how can i validate shapefile before converting,
and after converting what steps to validate data on the DB ?

i want to make a simple java desktop application that take shapefile and convert it
but first i want to check if shapefile has errors or not before starting converting it to my DB
can anyone help me ?

Thanks in advance
