I followed the installation instructions in the manual, but it is not working. Even after successfully compiling (using the command "ant compile") the downloaded jfreechart-1.0.19.zip file on my linux machine, running the jfreechart application (using the command "java -jar jfreechart-1.0.19.jar") gives the following error:
no main manifest attribute, in jfreechart-1.0.19.jar
When I looked in the manifest file, there is no Main-Class attribute, which is required.
The same issue was there when running the original jfreechart-1.0.19.jar file, without rebuilding using ant.
The demo file works fine though.
