Eclipse Java, Reporting with JFreeChart

Hi everyone,

I am creating a simple Business Intelligence Tool in Java using Eclipse. I only need this tool to get some information off a desired database and then create some graphs and tables (reports).

I can connect to an oracle database and get all the information off of it. But now I need to create the reports. I was told to check some packages on this website :
http://java-source.net/open-source/charting-and-reporting

I took a look at some of the possible packages and decided I would give JFreeChart a try. But the problem is I have no idea how to connect it to my Eclipse application.
Do I need to import it? Do I need a plugin?

Can someone give me a step by step walkthrough of what I need to do.

How do I add the Freechart jars to your project's build path?

You might want to look into JasperReports - that will help you actually generating the reports. JFreeChart only handles the charting part of it, but JasperReports will allow you to save them as pdf, excel, html files etc.
Last time I used JasperReports there was a standalone application that came on the side helping you to create reports. Since then, a couple of eclipse plugins popped up for it. Not sure if they cover the charting part though.

JasperReports looks really good, but I would have to use that software.... I want to use mine and just add a package that lets me create graphs/tables.....

Basically something that will allow me to click a button that will get all the relevant data and make a graph/table....


please help.
JFreeChart has a plugin I guess: http://cap.xore.de/cap.php?show=cap.deps

I used this plugin.... and now when I go to "About Eclipse Platfrom" and choose plugins.... it shows that I am using JFreeChart Plugin..... but when I try to use the demo:

eclipse still gives me errors in the imports.... as if I dont have any JFreeChart plugins....
You will probably have to manually set the classpath for the project to include the jfreechar jar file. Right-click on project name, select properties, go to build path, libraries and add the jar file (either using add if the jar file is located inside the project or add external jar if it's somewhere else.
I just tried that using add externel jars, and it gave me an error saying :

Could not write file : blablabla.classpath
weird...I would suggest creating a new Eclipse project from scratch and adding those files to it. Are there any chances you might be using a version control system? Like SourceSafe?
