I am using JFreeChart in a Java swing application. I did specify where the libraries are in my builder.xml file:

<zipgroupfileset dir="../lib" includes="jfreechart-0.9.21.jar" />
<zipgroupfileset dir="../lib" includes="jcommon-1.0.8.jar" />

I imported those libraries; Eclipse doesn't show any compilation error. But I am getting this when I run the code:

java.lang.NoSuchMethodError: org.jfree.data.xy.XYSeries.<init>(Ljava/lang/Comparable;)V

Could someone please help me figure out what's going on? Thank you!

Note that JCommon classes have been integrated into JFreeChart version 1.5.

When downloading old releases from here, be sure to use compatible versions: For example, the latest JFreeChart JAR, jfreechart-1.0.19, should be used with the latest JCommon JAR, jcommon-1.0.23. You should see the correct JCommon JAR in the lib folder of whichever JFreeChart you choose.

The current version can be obtained via or built as shown here.
