Classpath for ExcelDriver in AS/400 enviroment

Question

Hello there!
I'm trying to create application which would be capable copy excel file sheet to AS400 DB2 file.
First of all I created this program on Windows enviroment tryed and it works fine.In this program
Im using two drivers Microsoft Excel Driver(without DSN) for reading Excel file and AS/400 jt.400 driver for writing to AS/400 file.
My problem arised when I put the program into AS/400 enviroment and tryed to do same thing(copy Excel file which is in folder directory on AS/400 to AS/400 ordinary file).
I've got message in AS/400 enviroment:"java.sql.SQLException: No suitable driver"
Of course No suitable driver because I did not put Microsoft Excel Driver on AS/400 enviroment
and did not declare the classpath either.
Question is:Where can I get Microsoft Excel Driver so that put it into AS/400 enviroment?
If somebody need have a look into the source code here is it:

Is there a Microsoft Excel driver? If there is, its classname would very definitely not be "sun.jdbc.odbc.JdbcOdbcDriver". This forum has a link to FAQ at the top of the page listing posts, one of the FAQs has a link to a list of many drivers. You might find this driver listed there. Otherwise, don't be surprised if the AS/400 doesn't support ODBC.
