JFreeChart 1.0.14

[JohnEPearson]

I am new to Java and JFreeChart. I'm trying to get started using JFreeChart 1.0.14 with NetBeans.

I'm trying to create the first application in the documentation (Appendix C): MyAppThatUSesJFreeChart . I can't yet compile and am trying to debug.

I've added the JCommon and JFreeChart libraries. Under the libraries folder it now shows:

JCommon-1.0.18 - /Users/pearson/jcommon-1.0.18
JFreeChart-1.0.14 - jfreechart-1.0.14.jar
JDK 1.6 (Default)

Is this correct? When I added the libraries to NetBeans I was suprised that jfreechart and jcommon didn't have parallel directory structures.
jfreechart-1.0.14.jar is in jfreechart-1.0.14/lib while jcommon-1.0.18.jar is in: jcommon-1.0.18

For whatever reason the fix imports button in NetBeans did not add: import org.jfree.data.general.DefaultPieDataset;

I also had to change the name of the class from MyAppThatUsesJFreeChart to MyAppThatUsesJFreeChar (dropped the final t)
because I was getting a "duplicate class" error if I simply followed the instructions in the documentation: jfreechart-1.0.14 .

Once these two corrections were made the demo code in Appendix C ran. I hope the rest of the documentation is not as buggy.

It would be very usefull to have the JFreeChart version in the MANIFEST.MF file:

Code: Select all

Specification-Vendor: jFree.org
Specification-Title: jFreeChart
Specification-Version: 1.0.14

This can be checked via looking into the JAR's MANIFEST.MF but also with code:

Code: Select all

org.jfree.chart.JFreeChart.getClass().getPackage().getSpecificationVersion()

With this feature, applications using JFreeChart log its version and check against the current JFreeChart version.

Good suggestion. I'll provide this in the next release.
