write to excel on NT from unix (odbc/jdbc?)

[catalina mesa-moreno]

Hi!
My problem.
I have a webapplication on a Unix, webserver: websphere.
Now would i like to do some kind of odbc-jdbc to a NT and write to a excelsheet.
The only thing i would like to write to the sheet is a value to make excel understand that I would like to run a macro.
Is this possible?? Can I make an odbc-jdbc to a NT from a UNIX??? if yes How do I do it??
