where can I find the package org.jfree.ui and org.jfree.util ?

Those packages are part of JCommon.

Thanks a lot. Now I can compile the file but when I run it, it comes up with the following error.

Exception in thread "main" java.lang.ExceptionInInitializerError
at org.jfree.chart.ChartFactory.createPieChart(ChartFactory.java:242)
at First.main(First.java:17)
Caused by: java.util.MissingResourceException: Can't find bundle for base name org.jfree.chart.resources.JFreeChartResources, locale en_GB

at org.jfree.chart.JFreeChart.<clinit>(JFreeChart.java:230)
... 2 more

Please help.

now I fixed the bundle problem and I can run First.java successfully. However I got the following error msg when I ran LineChartDemo1:

F:\Works\Others\jfreechart-1.0.3\source>java LineChartDemo1
Exception in thread "main" java.lang.NoClassDefFoundError: LineChartDemo1 (wrong name: demo/LineChartDemo1)

How can I fix it? Thanks

You need to spend some time learning about packages, the classpath, and other Java fundamentals, before you start messing around with third party libraries like JFreeChart.

The "problem" here is that LineChartDemo1 is declared to be in the 'demo' package, so it should appear in a 'demo' subdirectory somewhere on your classpath. But you are running it with 'java LineChartDemo1', so it sounds like you compiled it in the top-level directory (you ought to be running it with 'java -classpath {your classpath here} demo.LineChartDemo1'.

i guess i really need to do some more study then

but anyway, it works now after I removed the line package demo.
