Re: JFor in a servlet

Hi,
i have developed a servlet for jfor. It works fine. I am using tomcat
server. The problem i am facing is the inputfile ie... fo file , its
neither taking relative path nor any other path. So i have to hardcode the
whole path. Can anyone help me on this. ( I am including the whole code
here..)

The current jfor code base does not include a servlet implementation that 
runs jfor.

If you want to contribute one (which would be nice), we (through the 
jfor-devel mailing list) would be happy to help.
