Pranav:
This is only my opinion but since you are using an automated technology in this
case Eclipse I would not use the ANT build approach. My ANT experience is only
in the world of web development so anything I might say would be of question.
Now, yes I would create a new project in Eclipse and import what you need from
the sample project. I myself just copy to and from the original source into a
pseudo framework. Now as for running such a beast, you will need to determine
the main and what I recommend is that you create a package under src that is
titled main.... Note the lower case "m". With in same create a class Main....
Note the upper case "M". This makes tasks such as running easier because you
merely need to specify main.Main as your entery point. Note once again the
cases of "M" in that example.

Hi Jim,
The project is a desktop application. I am trying to compile an example that
comes with the JfreeChart documentation. The way I am doing this is to just
open the *.java file in eclipse and then build that file. When I hit
alt+r+r, I am asked to select the ANT configuration.
Do I need to create a specific project before I import the *.java file?

Is this a web project? If not, why are you using ANT?

Hi all,
I am trying to compile the source code of a demo that has come with the
JfreeChart component. I have selected the ant build to be the build with
default options. I am getting an error. The stack trace is below. What am I
missing?
