Hello List

I have a simple feature in my web-application which exports the data from an 
Oracle Database to an Excel file. I implemented this by:
1. Form the tab separated string and put this in a StringBuffer
2. Set the StringBuffer as a Request attribute
3. In the JSP page, set the content type to application/vnd.ms-excel and write 
the content using out.println()

The problem is that there is 1 number column/field. When the data has leading 
zeros, the Excel drops the leading zeros.

Does the Jakarta POI api solve this problem?

The constraint I have is that I must not create files on the server. I have 
gone through a few examples and found that all are using FileOutputStream, 
which creates a file.
Is there a way I can use the POI api in my application without creating a 
physical file?


Thanks
Ravi
