I have implement Exporting Excel sheets in to Oracle Database Using ExcelDriver in Windows .. but it doesnot work in Linux cuz it doesn't know about ODBC Drivers. can any one help me what should i do to make it work in linux and Windows.. any suggestions
ODBC is probably not going to work on Linux. It's a Microsoft technology, and ofcourse Microsoft has no interest in making it available for any other OS than Windows.
There are, however, several options available to work with Excel spreadsheets from Java. Have a look at JExcelApi or Jakarta POI, for example. Ofcourse those APIs are different from what you already used, so you'll have to rewrite part of your application.
Search for "Java Excel API" with Google for more options.
