How to make a change,
June 21, 2009 at 10:43 PM

Hi.

The code is right for me except one thing. I don't read the file from the server. I create the file using POI-HSSF, so in the first line:
InputStream is = new FileInputStream(file); file is read from the server, but I have created and store for example in FileOutputStream.

is possible to make that change?

Thanks
